Should i buy an svbony sv503 80ed for Astrophotography on a low budget?

[fast badge]

What’s the budget, what mount and camera do you own

[shy narwhal]

Planning on buying a star Adventurer gti, with an zwo asi585mc color camera, budget ~€2.000

[trail haven]

The 80mm is too large then

[shy narwhal]

Because of the weight, or the tracking capabilities of the star Adventurer gti?

[flint bloom]

Svbony has a 70 mm quadruplet that is similar to the Askar 71F.

[shy narwhal]

So the 80mm is to heavy then?

[trail haven]

Imo too much focal length, other than the weight

I wouldn't personally go over 60mm in diameter

[shy narwhal]

Yea but the focal length is just what i was searching for. I already have a seestar s30, and wanted something that has more aputure, and more focal length, because the wide stuff (Andromeda, pleiades, North America Nebula...) are things I can already do with my seestar

[trail haven]

Gotta change the mount then, sagti + medium-long focal and 585 isn't a great combination

[shy narwhal]

Because of mount wobble, or the weight of the whole telescope rig on the sagti, or is the tracking just not superior enough on the sagti

[trail haven]

The mount itself isn't amazing on its own, adding a heavy-ish scope won't help and using a sensor with small pixels will require more accurate guiding

[shy narwhal]

And if i go for the svbony sv503 70ed, with an asi585mc color (or the air version with built in autoguiding) and a guiding system. Would that be perfect or still to heavy/zoomed in?

[trail haven]

Still both too heavy and zoomed in

Imo at least

What would your pixel scale be with the 70mm?

[eager fjord]

What about a second hand Redcat 51

[shy narwhal]

The pixelscale for the svbony 70ed, and asi585mc color is right around 1.42 arcsec/pixel

[shy narwhal]

Redcat 51 is an option, but i want to capture small things, sinds i can already do widefield photography with my Seestar s30

[flint bloom]

Your mount will be the limiting factor for deeper images.

[shy narwhal]

What do you mean by that? (Too much backlash, limiting weight capabilities)

[flint bloom]

Overall, as you go up in focal length you'll need a mount with higher payload capacity, better tracking, etc. You're better off investing in a higher capacity mount first before a longer focal length OTA

[shy narwhal]

So 420mm with asi585mc color is too zoomed in then?

[trail haven]

Rather than too zoomed in, it's too much for the sagti

[hollow shadow]

I use an Askar 65PHQ + 585 on a GTi, but it’s really pushing the limits of the mount

I have my guide settings mostly figured out by now and it works well enough for me but you gotta know what you’re doing

Every mount is different too, even between the same kinds of mounts have very slight differences. Yours won’t perform the exact same as anyone else’s, at least that’s unlikely

As in what works for your guiding won’t be the exact same as someone else

But anyways yes getting a better mount with more payload is important to do before longer focal length

[humble pumice]

I had around the same budget and just bought my rig if your interested

[shy narwhal]

Yeah of course! Show me what you got!

[shy narwhal]

And how heavy is your rig?

[hollow shadow]

Comes out to about 7.5lbs

Main scope, 585, guide scope and cam

I don’t have any sort of mini pc on there it’s just those

[humble pumice]

I got a SW 130PDS, EQ5 mount + OnStep goto Kit, Baader MPCC coma corrector and a Touptek [idk how to spell it] 585 cooled color cam

[humble pumice]

Pretty much exactly 1.8k

[shy narwhal]

Oh no way that 80mm scope is going to be in the weight limit of the skywatcher star Adventurer gti

[shy narwhal]

And is the GOTO kit precise?

[humble pumice]

Havent recieved it yet but alot of people on the server use it so i assume it is

[shy narwhal]

And was yours secondhand?

The mount?

[shy narwhal]

Your setup sounds really cool, but I'm not really into Newtonians, the smallest size I can get from a good brand is 8 inches, and that's just too big for me. I plan on traveling with my setup, so a newton is probably not going to be it

[humble pumice]

Nope, bought everything new

[humble pumice]

Hm, got ya. But the EQ5 and OnStep is definately a good shout. Also refrain from ZWO where possible

[shy narwhal]

Alright, il do a bit of research on that eq 5 mount. Thanks! Which brand was your eq5? Skywatcher?

[humble pumice]

yep, Skywatcher EQ5

[shy narwhal]

Alright, the skywatcher gti also has a pack where you can get a telescope with te gti, i believe it's a skywatcher 60mm with a focal length of 400mm. Would that be an option?

[humble pumice]

depends what you wanna do with it and what telescope

[shy narwhal]

The telescope is an skywatcher evolux 60/400

Wanna do deep sky imaging with high focal length, but since thats not really an option with the skywatcher star Adventurer gti i will probably do wider field, or look into that eq 5 mount

[humble pumice]

i got told that the Evolux series isnt amazing

[hollow shadow]

I still think a shorter focal length less than 400mm would be a better choice if you go with the gti

So if you get a gti then go with a redcat or sqa55

But if you go with a larger mount like that eq5 then by all means go long

[humble pumice]

(EQ5 + Onstep is robably cheaper than the GTI btw)

[shy narwhal]

And if i go for the eq5, can i probably put an 102mm refractor, or is that to large for this mount?

[shy narwhal]

For me it's about the same price

[humble pumice]

How heavy is it?

[shy narwhal]

The ota with tube rings is about 5.7 kilos or 12-13 pounds

But wit asiair mini and camera and accesoires it wil probably be right around 6 kilos

If the weight is fine, the 102ed is even better than the 80ed. Pop on my canon 200d apsc sensor and you have a relatively wide field

Pop on the main imaging sensor (asi585) and you got a nice zoomed in shot

[ripe creek]

I have a redcat 51 and I can take maximum 3m subexposures guided with excellent PA and a pixel scale of about 4" pp

So I completely agree with you

My mount is the weak point of my whole setup

[shy narwhal]

Yes, but I was not planning on doing 3 minute subs, with an 62mm scope, i was planning on max 60,90sec

[ripe creek]

60mm will be fine

80mm getting problematic

I also opened mine up and realised that the worm gear inside is plastic

So imo the star adventurer GTI shouldn't be overloaded for imaging

I would imagine that the higher load you put on the more it will wear out

I'm doing imaging rn I'll show you pics of my guide graph

My rig combined is like 2.7kg

Pushing 3 I think with some new accessories i put on

Alot of periodic error as well

Maybe it's just my copy

I've seen people really overload their gti's with like 6 inch newts and stuff

So maybe they just got lucky with good copies

Imo something in 250-350mm fl will be good match

Preferably in the lower end

Of that range

Another wierd moment of periodic error

Have a look at the skywatcher eqal55i

Just looked rn and there's no stock anywhere

[trail haven]

For nebulae that's the kind of exposure time you want to do

[shy narwhal]

What? 3 mins or 60-90sec?

Looking at that graph, there are some hefty spikes

So does anyone know any EQ mount that can support at least 5-8kg (sagti can't cope this load) that is pretty cheap (like I don't wanna spend all of my 2000/2500€ budget on an am3)

[trail haven]

3m

Or more, my minimum is 5m

[trail haven]

Ragdoll 17

The base model is 1300$ rn

Or my umi17

[shy narwhal]

Hahaha

And a skywatcher eq5 pro synscan goto

In use with an asiair mini?

[shy narwhal]

Hahah what do you like so much about the ragdoll 17 opposed to lets say like an am5

[ripe creek]

big update guys

Changed the settings on phd2 Dec guiding algorithms to hysteresis and now I'm getting sub arcsecond

[humble pumice]

more expensive and less easy to use than OnStep

[ripe creek]

No big jump so far

So maybe the problem was me and not the mount

[shy narwhal]

Is an onstep upgrade hard to install?

And which one do you recommend?

[humble pumice]

from the tutorials ive watched its easy

[ripe creek]

Depends what kind of mount ur putting it on

If you are planning on upgrading a non goto mount by adding smth like NEMA 17 motors and onstep

Then there are kits but I still wouldn't recommend it unless you have worked with building your own electronic systems before

[humble pumice]

Nahhh, OnStep is legit like 5 screws

[ripe creek]

What Abt stepper drivers

Huge pain in the bum getting the right drivers

And calibration for the motors

Idk I have no experience I can't be talking

With onstel specifically

[trail haven]

Price mostly, better support, FRAM

[humble pumice]

its plug and Play

[trail haven]

You don't really have to build anything tho

[ripe creek]

I've had a huge building a mount obsession for a long time

[humble pumice]

legit download ASCOM and use it with NINA

[ripe creek]

You r bringing me closer to it

[humble pumice]

https://www.terransindustry.com/collections/allproduct/products/skywatcher-eq5?variant=42553929826497
This is what i got myself

[ripe creek]

Also for buying any eq goto mount, aren't the juwei 14 mounts litrelly like the cheapest on the market

[ripe creek]

This is super cheap as well

[humble pumice]

exactly, payed like 600 for this + and EQ5

[shy narwhal]

So is the onstep upgrade kit (like the terran) easy to install like just pop in a few screws and you're done, or do you need to pry open the whole mount?

And does it work with asiair mini?

[humble pumice]

nope, legit just a few screws and thats it

[humble pumice]

no clue but why use an ASIAir anyways?

[shy narwhal]

So I can control everything from my phone, and process it later on my computer

Also

When I'm on vacation I don't feel like bringing my laptop so il store all my subs on an drive or an sd card and process it later when I'm back home

[humble pumice]

OnStep has a phone control

But idk if it works with ASI

[humble pumice]

Good news

[shy narwhal]

Niceeeee

And if you pop in an onstep kit, do you need to calibrate it or something like that?

Or does it just work out of the box

[humble pumice]

just works from what ive seen. if you wait a week or 2 i can give you a first hand review

[shy narwhal]

Thanks, I'll be happy to hear from you

[trail haven]

there are plenty of users with that onstep kit here, it's pretty much plug and play

my mount works on the same platform

[shy narwhal]

Nice to know

[ripe creek]

Imo getting an eq5 or similar and then upgrading it will give you much better raw performance than a swsa gti

[tulip girder]

Why not a cheap harmonic mount? There are some that are not much more expensive than the sa gti.

Juwei 17 for example

[trail haven]

I don't like them because there's 0 support after purchase, but they're as valid as the others otherwise

maybe a bit less QC and less accurate strain wave gears but still fine

their juwei 14 is interesting, 800€ for am3 like payload

[shy narwhal]

Yes but with mounts like am3 you get good customer support, and you can look things up online, bc so much people have a mount like an am3, but for those Chinese mounts you dont get those things

[trail haven]

zwo customer support isn't that good, it's full of stories of people getting defective AM3/5 mounts who had to go through hell and back to get a replacement or that just got told to eat shit

it's kinda why I suggest mostly proxisky mounts, they're always there to help and have already replaced several stolen stuff or mounts at no cost for the buyer

[shy narwhal]

Oh thats a shame on zwo. I thought their customer service was always top notch

[ripe creek]

They're very apple like in their customer service

ZWO is basically the apple of astro

[glad meadow]

Get a sv555 54mm 😉

Got a 585 aswell

[lament wren]

Yo our rigs are practically the same

[shy narwhal]

Why should i get an sv555? Or did you mean "got a sv555 54mm"?

[glad meadow]

The Problem is with ur Sensor

You Can only Shoot small stuff with the Scope you want

[shy narwhal]

Yeah that's kinda the plan

[glad meadow]

What Mount you got

You Need one with a very small error then

[shy narwhal]

Was planning on buying the star Adventurer gti or a skywatcher eq5 with onstep kit

[heavy sable]

If youre on a budget I wouldn't get ZWO in the first place

[shy narwhal]

Are there any other cameras that work with asiair then?

[glad meadow]

If he can spend 2k he can get a proxisky ragdoll

[heavy sable]

Why do you want asiair?

[glad meadow]

Get stellavita

😉

[shy narwhal]

So I can control everything from phone

[glad meadow]

StellaVita Not asiair

[heavy sable]

ToupTek Stellavita or you just get a minipc + cygnus app

[shy narwhal]

Why stellavita

[glad meadow]

Asiair only works with zwo stuff

StellaVita with almost every

[heavy sable]

literally just an asiair but compatible with basically everything

• you actually get proper customer service

[shy narwhal]

But does stellavita have a good reputation

[glad meadow]

Got StellaVita Myself

[glad meadow]

It’s new

Ofc not

But it works

…

[shy narwhal]

Hahah alright

Wil look into that rhen

Then

[heavy sable]

if you are worried about the bad start it had

[glad meadow]

Im using it for a year almost

[heavy sable]

its no longer that bad

still a few issues but way better than the asiair in terms of budgetting

you could also just do minipc + nina

with the cygnus app

[shy narwhal]

Nah I want a plug and play system

[glad meadow]

Then stellavita

[shy narwhal]

I have basically two left hands

[glad meadow]

Nina is not plug n play

Thats just the mobile app

You still need a pc with everything on and configured right

Unlike on the sv

[heavy sable]

honestly it depends on what you want, if you really want plug and play then do SV

tbh in some areas the price of a 585MC pro is the price of the ToupTek ATR585M Kit (with everythin u need for mono)

[glad meadow]

I wouldnt get mono at first

But i guess he knows how to stack and edit

[shy narwhal]

About that

No

I dont know how to stack

I'm a beginner

[glad meadow]

Get a 585 from touptek

The color version

[shy narwhal]

I have a seestar now

[glad meadow]

Get the sv555

[shy narwhal]

Why sv555

[glad meadow]

For a mount

[heavy sable]

the Uranus-C is better imo

[glad meadow]

Star adventurer gti

[heavy sable]

What kind of advice is that

the GTI is absolute ass

EQ5 + Onstep all the way

[glad meadow]

If he wants to spend that much money on a mount sure

[shy narwhal]

Yeah but it's kinda bulky isn'it

[glad meadow]

….

[heavy sable]

The thing iwth the GTI is

[glad meadow]

Never had a eq6r or heq5 right?

Thats bulky

[heavy sable]

it has a terrible payload and for 700 bucks its INSANELY bad

[glad meadow]

Used 400€

[shy narwhal]

Alright

[heavy sable]

Evenfor 400 you barely think you didnt get ripped off

[shy narwhal]

Eq5 is about same price here in the Netherlands

[heavy sable]

If you want a non-bulky one go with the Juwei 14

Its a harmonic mount with the payload of an HEQ5

[shy narwhal]

But is it solid

[glad meadow]

Yes

[heavy sable]

yes

last i checked it costs 800 here in germany

[glad meadow]

And doesnt weigh 17 kilos like the heq5

[shy narwhal]

Alright but i dont wanna spend money on a thing from China that does t work (i know everything comes from China but you get the point)

[heavy sable]

tbh the HEQ5 aint that heavy. i carry it in and out of the house completely assembled with counterweights every time

[heavy sable]

I can assure you juwei mounts are very functional and VERY good.

[glad meadow]

Try to be mobile with the heq5

I live near b2 and in a b4

Thats why i bought the ragdoll 17 pro with their carbon tripod

[shy narwhal]

So touptek camera, stellavita, and telescope

[heavy sable]

https://www.youtube.com/watch?v=Az3xagKDpMk

Id recommend the Uranus-C Pro as a camera

[shy narwhal]

Why

[glad meadow]

https://www.touptekastro.com/en-eu/products/stellavita?_pos=1&_sid=8d88e5f7a&_ss=r

[glad meadow]

But the ac version right

[heavy sable]

Player-One Astronomy has goated customer service, the firmware is (argueably) better and the casing is INSANELY well made

[heavy sable]

The TEC cooled one yes

https://svbony.eu/produkt/sv555-f9395a-apochromatisches-teleobjektiv-teleskop-54mm-f-4-5-ed-mit-eaf-montageset

[shy narwhal]

Oooh looks fancy🤑

[heavy sable]

costs 500 usd

[glad meadow]

And a guider aswell

Or you wanna do oag?

Like me if you scroll up

[heavy sable]

id recommend an OAG if you are all for compact

[heavy sable]

P1 cams look insanely good

all of them are so sexy its insane

[shy narwhal]

I'm sorry guys but what's oag

[heavy sable]

Off-Axis Guider

[glad meadow]

Off axis guiding

Look at my blue camera on the back

[heavy sable]

Its a ring you attach in the optical train with a prism which directs spare light (that misses your main camera sensor) into a guide camera

[glad meadow]

Normaly u use a guide scope for ur guider, but with a oag it uses ur main scope

With this you got a bigger aperature and more focal lenght

[shy narwhal]

Yeyeyeye now I know

[glad meadow]

I would use oag till like 1200mm

[shy narwhal]

I had heard of it

[heavy sable]

OAGs are to be used beyond 1200mm

[shy narwhal]

Looks compact

[heavy sable]

Oh it is

[glad meadow]

Do that with 2000mm and find a star …

[heavy sable]

Use a high sensitivity sensor which is fairly large

like the Xena-M

[glad meadow]

I use the uh

Gpm462m

From touptek

[heavy sable]

its a tiny sensor so yeah i get what you mean but

a guidescope at such long focal lengths isnt going to do you justice

[glad meadow]

Better then using this small sensor at 2000mm

[heavy sable]

thats the issue lmaoo

[heavy sable]

Its very worth it if you want a compact and simple setuop

[shy narwhal]

Yeah but I want everything to kinda fit into a backpack (tripod can't fit ofc)

[heavy sable]

An OAG is the best option then

[shy narwhal]

Ok but isn't eq5 to big than?

[heavy sable]

Oh so you dont want the Juwei 14?

[shy narwhal]

Ye but no but ye cause eq5 has a reputation for being good

[heavy sable]

The EQ5 certainly wont fit in a backpack but neither will anything due to the tripod

[shy narwhal]

Tripod ain't gonna fit in a backpack ofc

[heavy sable]

Juwei 14 also does

Anyhow, the EQ5 is pretty heavy but not that heavy, you could indeed get a carrying case/bag for it though

[shy narwhal]

Only time when I go anywhere is when I go on vacation, but in the back of the car also need to be space for luggage

So I want something good

Eq5

[glad meadow]

Juewei

[shy narwhal]

But also compact

Juwei

[glad meadow]

Or proxisky ragdoll 17

A am5 for 1300€

[shy narwhal]

Yeah but i have an limited bidget

Like 2500-2700 euro

[heavy sable]

You can do plenty withhh that lol

[glad meadow]

For everything?

[shy narwhal]

Yeah

[heavy sable]

a bit over the top dont you think

[shy narwhal]

But less is always better

[heavy sable]

20kg payload for a compact setup

[glad meadow]

Are u dutch?

[shy narwhal]

Haha

[heavy sable]

Understandable

[shy narwhal]

Yeah how you know

[glad meadow]

Bc u said that

Dutch prices

[shy narwhal]

Oh

Haha

[glad meadow]

So i can make a german list for you

Bc prices will be the same

[shy narwhal]

Yeah

Nice

Das ist gut

[glad meadow]

Very

[shy narwhal]

(i dont know German that well)

[heavy sable]

german supremacy

anyhow

[glad meadow]

Wraaaah

[heavy sable]

So given you want a refrac i am assuming you want to do widefield?

or is it just for the sake of being compact

[shy narwhal]

Compact but nice enough to see details from m51 and small galaxys (like 500-600 mm fl

[glad meadow]

A 585 with sv555 is good then

[shy narwhal]

What is fl on sv55

[heavy sable]

255mm focal length?

[shy narwhal]

5

Hahaha

[glad meadow]

With a 585 foc

Fov

[shy narwhal]

I meant 500mm fl + 585

[glad meadow]

Also he wants to be mobile

[heavy sable]

not enough for small galaxies or m51

[shy narwhal]

Oh

Chatgpt ain't right then

[heavy sable]

oh god

do NOT ever listen to chatgpt for astro advice

PLEASE do not

[shy narwhal]

Okidoki

[shy narwhal]

That's why I came here

[heavy sable]

You will have better detail with your seestar

[shy narwhal]

Hmmmm seestar s30 is pretty wide

[heavy sable]

You could do an F/4 6'' Newton

[shy narwhal]

Yeah but I'm not into newts. There heavy, not compact

Needs collimation

[heavy sable]

Well you have to pick unfortunately.

either get someone extremely expensive for that focal range or a reflector

[heavy sable]

an F/4 6'' weighs 5.5kg for reference

[shy narwhal]

And if I start widefield with star Adventurer gti for example with 60 mm refractor

And if i get the hang of it

[heavy sable]

oh for the love of god do not get a GTI

[shy narwhal]

Then upgrade to something bigger

[glad meadow]

Let me make u a list

For 2700€

[heavy sable]

you can get anything but a GTI, its CRIMINAL

[shy narwhal]

Why does everyone hates these

[shy narwhal]

Alright thanks

[glad meadow]

Newton is best for imaging

[heavy sable]

F/4 is fast, compact and it has the most power for the price

[heavy sable]

hate?

[glad meadow]

Got f3.45 on my newton

[heavy sable]

[shy narwhal]

Mmmm everyone doesn't like these

[heavy sable]

#1405674934734422016 message

[glad meadow]

Quattro 150p modded with cnc spider and mirror ring

[shy narwhal]

But I really don't want a newt

[heavy sable]

You will have to settle for a reflector for galatic imaging or well, a REALLY expensive refractor

[shy narwhal]

And if I do widefield

[heavy sable]

refracs are made for widefield

[shy narwhal]

300-400 fl

[heavy sable]

reflectors get expensive as shit when it comes to widefield

[shy narwhal]

And pair it with a tiny sensor

[heavy sable]

also gets hella expensive toward that range

[heavy sable]

tbh focal length isnt what is going to limit you for detail on galaxies

its the lack of aperture

[shy narwhal]

Svbony is cheap, refractors from skywatcher are cheap

[heavy sable]

For a reason

though i guess the evostar 71ed isnt that shabby

Yeah afaik the 71ed will be your best shot

[shy narwhal]

But is star Adventurer gti THAT bad?

Bc I've never held a eq6 r pro in my hand for example

So gti seemed like a good product

[glad meadow]

Eq6 is massive

…

[shy narwhal]

I know but it was just an example

@hollow shadow is also in this server and has a gti and a 65mm refractor

[heavy sable]

If it cost like 300 bucks yeah it would be fine

But 700 bucks for a piece of shit which can barely hold a mini refractor? Yeah no

[heavy sable]

EQ6r is for heavy stuff

[shy narwhal]

Yeah but it's portable

[heavy sable]

Mainly the most expensive of refractors an large reflectors

[shy narwhal]

Yeah I know but it was a comparison

Gti didn't seem bad

[heavy sable]

@coarse spoke explain your experience with it to him lol

[heavy sable]

The GTI ain’t something I’d ever recommend to anyone in any case

[shy narwhal]

But is gti that bad, cause I've seen some amazing pictures, and if you use guiding it shouldn't be bad?

Or

Does it

[heavy sable]

The GTI is certainly useable

But it’s such a hassle and for the price it’s just… bad.

[tired plinth]

a

[shy narwhal]

I come from a seestar, I don't know mounts that well

[shy narwhal]

Agreed

Very nice

[heavy sable]

Do some research on the Juwei 14, if you don’t trust it that’s fine but do not get the gti new

[tired plinth]

Well I’m from a seestar s50 and got a big ahh 10” goto dobson

juwei 14 and 17 are amazingly good

[shy narwhal]

Would you say it's better than gti?

[tired plinth]

for sure

[shy narwhal]

?

What about guiding

[tired plinth]

gti’s do the job but now you get better for the same price

[tired plinth]

svbony 50mm and a touptek cam

[heavy sable]

People can get amazing stuff with it yes

[tired plinth]

but it isnt worth it

[heavy sable]

But you have to ask yourself, can you?

[shy narwhal]

No

I surely cant

I don't even know how to stack

[heavy sable]

Can you replicate the pain and modifications the people made to it

[glad meadow]

Im stuck at 3k

[heavy sable]

Can you replicate the equipment used to make it functional

Astro its ur own thing now if you wanna switch

But i can say the sv555 is good

@cobalt marsh

You know it better then we do

[heavy sable]

Haha redcats are good too but if it doesn’t fit in the budget it just doesn’t fit

[shy narwhal]

But is juwei 14 easy to use cause I have like two left hands if you know what I mean

[glad meadow]

Yes

[shy narwhal]

I am not a diyer

[glad meadow]

Same as eq5 xd

[heavy sable]

You forgot something

[glad meadow]

What

Psu

[heavy sable]

Player One prices are in USD

[glad meadow]

Almost the same as euro

[heavy sable]

Convert them to Euro and you loose a couple hubdred

[glad meadow]

Almost 1:1

But tax

[heavy sable]

Nope

[glad meadow]

Import tax

[heavy sable]

I bought from them it’s included

[glad meadow]

Thats why it will be around 3000

[heavy sable]

The import tax is included

[glad meadow]

Ah

[heavy sable]

In the price

[tired plinth]

perfect setup

[glad meadow]

But this is a mix of euro and dollars

I alleays calc usd 1:1 to euro because of taxes in germany

[heavy sable]

All the player one stuff is 720 Euro

[glad meadow]

But @cobalt marsh can help you better then we do

[shy narwhal]

And what are the pros with a cooled camera?

[heavy sable]

So take off another 120 bucks

[heavy sable]

Basically 0 thermal noise

[cobalt marsh]

The Svbony SV555 is not only good, but almost a competitor for the price. It's a full-fledged APO, meaning it's color-accurate and corrected up to full frame, and all for a price that you might get duplicates from the competition. There are countless comparisons; for example, it performs better than the significantly more expensive Redcat.

[heavy sable]

And you don’t have to reshoot calibration frames every night

[glad meadow]

And u dont need to redo darks

[heavy sable]

Yeah

[shy narwhal]

Oooh fancy

Sounds nice

[glad meadow]

@shy narwhal here u go, andreas is here and he can def help u

[heavy sable]

If you’re lazy a TEC camera is way better.

[shy narwhal]

Why

What's tec

[heavy sable]

Thermoelectric Cooler

[shy narwhal]

Sounds expensive

[glad meadow]

Can cool ur camera down to like -30 degrees

[heavy sable]

It’s a 170 buck upcharge last I checked

[shy narwhal]

Why would you ever want that

[glad meadow]

Less noise

[heavy sable]

Thermal Noise

The warmer your sensor the more noise you get

[cobalt marsh]

Alternatively, I would recommend an IMX533 camera instead of the IMX585. The SVBONY SV605C, for example, costs exactly the same but has a better sensor.

[heavy sable]

But beyond -15 it’s redundant

[heavy sable]

the 533 being better than the 585 is the most controversial topic OAT lmao

[cobalt marsh]

Thermal noise. This is stronger the warmer the sensor is. At or below 0°C, it is virtually completely gone.

[heavy sable]

The SV605C is not compatible with the Stellavita

Only one single camera from svbony is for some reason

[cobalt marsh]

What's controversial about it? Larger sensor, more full-wave, depending on the camera, more bit depth. So, on paper alone, the 533 is better. But I have both, and I speak firsthand. Does Kodak say that the 585 is bad, especially at shorter focal lengths? Still, I'd prefer the 533, especially if the price is the same.

[cobalt marsh]

but it is... and yes tested.

[heavy sable]

It depends on your use for it

I personally enjoy the high sensitivity and its versatility in planets and DSO

[heavy sable]

ToupTek doesn’t state it is so I based it off that

[glad meadow]

He knows what he is saying

[heavy sable]

The SV605C also has less fullwell than the P1 models

[cobalt marsh]

I don't dispute that at all. The 585 is a jack of all trades. It can do everything, just nothing perfectly. And if it's exclusively deep sky, I would prefer the 533 (this is my personal opinion based on my experience).

[heavy sable]

And you must note that the price is just a little less than the P1 models in EUR (if you consider 80 bucks a "little")

[heavy sable]

Understandable

[coarse spoke]

Take it from me, don't buy it

[heavy sable]

This is missing filters as well btw lol

The SV220 is very nice

[coarse spoke]

It has planetary gearing with unfixable periodic error due to part of the gear being flat

[cobalt marsh]

I said some models. Many IMX585s only have 12-bit and 38k full-wave...

[coarse spoke]

It can carry only a small load efficiently and it's overpriced

I don't even think I'd buy it for 350€ and I own one

[heavy sable]

Thats why the same sensor doesnt mean the same product

Id personally go with the Ares-C if a 533 sensor is wanted since 80 bucks is worth it for the extra full well, the accessories it comes with and the general P1 customer service and look

But ultimately its up to AstroCas

[shy narwhal]

But there's nothing wrong If I go for an 585 sensor? I personally don't like a square sensor

[coarse spoke]

I love my 585

[heavy sable]

The 585 and 533 are both INSANELY good sensors

[coarse spoke]

It's just a small sensor, but if it doesn't bother you it's a great choice

[heavy sable]

You cant go wrong with either

[cobalt marsh]

Well, I went by price; he had an IMX585 listed for around €500. So my alternative should also be in that price range...

[shy narwhal]

Alright, so juwei 14, 585 sensor, something like an evostar 71

[heavy sable]

The list he put didnt account for the USD to EUR conversion

[coarse spoke]

I say avoid the evostars, they're not really good fracs iirc

[heavy sable]

Given that shipping and import tax is included, the Uranus-C Pro costs 430 euro

[coarse spoke]

A juwei 14 can handle a decent payload, you could get a 6 inch imaging newt for less than a Evo 71

[cobalt marsh]

Of course not, absolutely good camera, I just wanted to list alternatives

[heavy sable]

ive heard theyre pretty good for the price

[shy narwhal]

So what refractor in the 70-80mm range do you recommend on a budget?

[coarse spoke]

How much are they again?

[heavy sable]

Like 400 or something

but wait #1405477195379511297 message

[cobalt marsh]

These are dublets, right?

[coarse spoke]

Could get a 6 inch for that

[heavy sable]

He doesnt want a newt

[coarse spoke]

Yes

How come

Portability?

[heavy sable]

Portability and collimation

[coarse spoke]

Collimation is pretty straight forward but I get the portability part

[heavy sable]

here are some things fenice shot with the evostar https://telescopius.com/profile/daniele_p?order=is_featured&page=1

[cobalt marsh]

The SVBony SV550 80mm APO would also be an inexpensive but very good alternative. A full-fledged triplet APO, including a flattener and rotator, is available for only €570. Price-wise, it's unrivaled.

small example for a combination

[heavy sable]

840 - Juwei 14 (Aliexpress / Ebay)
684 - Uranus-C Pro + OAG + Filter Drawer Mini + OAG Mini + UV/IR Cut filter
300 - StellaVita (ToupTek Astro)
570 - SV555
137 - Ceres 462M
40 - Juwei 14 to EQ5 Tripod Adapter
180 - EQ5 Tripod
40 - CW Bar and Weight
82 - SV220 Duo-Narrowband Filter

2833€
@shy narwhal

Everythhing you need

This is a GOATED setup

[cobalt marsh]

As an alternative to the 555, you could also go for the 550, since they're currently priced at about the same price. It depends on what you want. Otherwise, a great combination 👍🏼

[shy narwhal]

Thanks yall

[cobalt marsh]

although, then I would add the Gemini EAF, 50-60€ at AliExpress, and you have direct autofocus

[heavy sable]

Oh right I forgot

[cobalt marsh]

If you want to round it off, you could add the automatic flat panel from Gemini. It costs €135, but there are discounts for those over 18, so I think you'd get another €25 off.
of course only if you want

Like this

[heavy sable]

Rather than a flatpanel i believe the powerbox is a better pick so its compacter

[cobalt marsh]

or both 😉😅

[heavy sable]

https://tenor.com/view/danny-devito-its-always-sunny-applaud-happy-cry-clapping-gif-18958303

[coarse spoke]

Lovely compact rig

[coarse spoke]

What flats panel are you using? I don't recall Gemini making one that small and I've been looking for one small enough for my frac 👀

[cobalt marsh]

yes really compact, light, and a great quality

[coarse spoke]

Is it a gemini though ? If so, what size

[cobalt marsh]

This is the Gemini 100mm flat panel. It fits perfectly on the SV555.

[coarse spoke]

Very beautiful, I might get one for my askar

[cobalt marsh]

but on the e.g. sv550 80mm

[cobalt marsh]

here is the same on it

[coarse spoke]

It'll be oversized for my FMA180 Pro, but what can I do 😂

[cobalt marsh]

I know, I still have the 150 mm version, because I thought the 100mm is too small for the 550... but it just fit

that's how it was before 😂🙈

In the end, of course, it's always better to be too big than too small. The main thing is that the flats are good. But too big (which was the case with me before) is also annoying, as you can constantly get stuck on the panel.

[coarse spoke]

Mine will probably look simlar to that 😂 Just at a smaller scale

[cobalt marsh]

How many mm is the outer diameter of the dew cap? I also underestimated it with the 555, thinking it would be smaller.

[glad meadow]

Gonna Order myself the Same one 😉

[cobalt marsh]

is really great for the price.

Now I just need one more for the 150pds...

[coarse spoke]

58mm, so even the 100mm one will be big lol

[cobalt marsh]

😅 OK, thats small 😅

I just see the dew cap is not really thicker than the telescope itself

[coarse spoke]

yeah, 40mm of aperture and a 58mm dew shield

[cobalt marsh]

for comparison, sv555 54mm aperture, 94mm dew cap

[shy narwhal]

What do you guys recommend for refractor for the juwei 14? Is a 80mm finally the good size?

[heavy sable]

the sv555 is probably the best for the price, the aperture will only help if you have good optics for it

[shy narwhal]

Yeah but if I have an juwei 14 I could go higher in fl since my tracking will be better right?

[heavy sable]

Yes surely, but I would believe its smarter to upgrade FL later

[shy narwhal]

Bc its easier right?

[heavy sable]

The setup you have is basically upgradeable in every category, its smarter to go with the most optimal option and see if you even end up needing more FL

[shy narwhal]

Right
