Evoguide 50ED with Uranus C and SWSA 2i. Will this be a solid setup?

#

#

It sure is usable, but is it worth it?

sharp sinew
#

yes

modest temple
#

I mean, guidescope ap?

I mean, sure go for it

#

I ve heard that the 62ed isn't that great @sharp sinew

#

It has chromatic aberration

sharp sinew
#

Its an APO bro

#

Those are made to not have these

clear swan
#

I know, i wanted to buy the same but when I asked here they said that the glass elements aren't good and you get chromatic aberration

#

It's true

@fathom marsh has an identical setup

errant hatch
#

yes it will

#

sorry wrong fin lmfao, @fathom marsh

#

i used a swsa 2i + evoguide 50ed with a dlsr, worked great

Alright.

I wouldnt even get the 50ed for guiding

#

its more of a imaging scope

#

idk why skywatcher advertises it for guiding

lucid moat
#

if you have the extra cash you might want to think about guiding

elder meteor
#

you'll also need the starizona field flattener

I like em hexagonal

I would go for a triplet instead of the evoguide. https://telescopescanada.ca/products/askar-fma180-pro-sextuplet-180mm-astrograph-lens-fma180pro

Askar FMA180 Pro Sextuplet 180mm Astrograph Lens - FMA180PRO

To provide customers with more options, Askar has launched the new FMA180 pro. FMA180pro adopts a sextuplet air-spaced APO design with three lenses in front and three in the rear, two of which are ED glass,providing excellent correction of chromatic aberration, which lays the foundation for high-quality astrophotograph

wish it told you what the glass was

#

if its better than ED glass why dont they say it as a flex lol

#

ED glass is still decent

Perhaps. Stars are rather bloated from images I’ve seen

#

get Roki

sharp sinew
gleaming sorrel
#

B3 and Roki? Beast.

wanton forge
#

True

#

If you don't have a full frame sensor

gleaming sorrel
#

My Roki corrected to a full frame perfectly fine. And I know QQQs corrects to FF.

sick ridge
#

Sure its fast, but you have to realize your copy is a lottery copy.. no one else will have one as good as yours

#

It's tough to recommend something you have to return several times to get a decent one, when you can get a scope with QC that works as intended

errant hatch
sick ridge
#

just because he has a good one doesnt mean others will be able to get good ones

errant hatch
#

Is there a limit for how many you can return?

sick ridge
#

just buy a reliable telescope

sick ridge
#

if you return 10 damn rokis they're gonna run out of stock and whoever you return it by will get suspicious eventually

errant hatch
#

Well, if you understand you will need to return it a couple of times and are happy with that then I would say it should be fine. Or just buy used

sick ridge
#

I once again say to just buy a reliable telescope

#

People will fight me for this statement but its not wrong

#

Stop telling beginners to buy rokis

ember adder
sick ridge
#

Or at least, not acceptable for F2, which is the only reason you'd buy a Roki

#

If you're going to stop down the Roki to f/4 to get decent stars(which most HAVE to do), you may as well buy an Askar 135. An actual telescope, intended for astrophotography

#

If you manage to get a roki that performs well at f/2, then its going to be better than anything in the price range tbf. My point is that.. a copy that good is so rare the odds of getting one are too low to even bother. literally a lottery lens

ember adder
sick ridge
#

congratulations then

#

a roki that good is really rare

#

I only know of 2 rokis that can perform well at F/2. LMC's and yours then

ember adder
#

Fair enough I guess I can only gauge my experience.

sick ridge
#

thats fair

#

again, if you get a roki that good its amazing

#

I don't speak from my personal experience, only the experience of others I know

#

took a friend of mine 3 returns to get a roki that performed acceptable at f/2.8

#

one of my friends got a roki that didnt even perform well at f/4, and wasnt able to return it. not the shops fault though

#

one I know got a roki that was good at f/4, returned it and got another f/4 one, sent it to a shop and got it to work at f/2.8

#

plenty more cases that I couldn't name off the top of my head

#

average roki performs well with a flat field at f/4, and most good copies can only do f/2.8

#

f/2 is very rare

#

I could never recommend a lottery lens like this to a beginner.

#

if you're going to recommend a roki, at the very least make the person aware of the trouble they may have to go through to get one that works good

#

Bad copies are in fact rare

#

The only person I know with a bad copy is Caphe, and some other guy I forgot about. Caphe was talking non stop about how bad it was, when realistically he was salty he couldn’t return it.

#

Have you ever used a Roki? No? Therefore opinion invalid.

sick ridge
gleaming sorrel
#

I don’t have a personal opinion on them.

sick ridge
#

Even if I did own a Roki it doesnt matter as my data comes from other people, my opinion alone wouldn't be enough to state how many Rokis are good

gleaming sorrel
#

Every time someone buys a Roki I’ll look at their test subs, look at the corners and make a note of it.

sick ridge
#

Understood

sick ridge
gleaming sorrel
#

It’s came out to about 80% good, 20% very good and 10% bad.

#

That’s after looking at 30 odd lenses

sick ridge
#

F/2?

gleaming sorrel
#

Yea.

sick ridge
#

Interesting, the only copy ive personally seen that was good at f/2 is yours

gleaming sorrel
#

Most are very usable at f/2. The majority are good at 2.8.

gleaming sorrel
#

My copy is actually semi average. It’s not 10/10

sick ridge
#

saved it anywhere id guess?

gleaming sorrel
#

Che shoots at f2 I believe. So does indiannah. And QQQ.

sick ridge
#

Doesnt Che have a sigma 1.8

gleaming sorrel
#

The others I’ll have to dig very deep for

gleaming sorrel
sick ridge
#

Didnt know

#

that ones pretty good

gleaming sorrel
#

You’re probably thinking of his 40 1.4 art

sick ridge
#

well I apologize for the misunderstanding, didnt know you actually had sources

#

I have less data, like only 10 rokis

#

not organized

#

from what i was going off, most were good at f/4, some at f2.8, and rarely at f2

ember adder
#

There is a whole roki owners forum full of people with great experience and one with a really bad experience as @gleaming sorrel says. Based on mine I wouldn't hesitate to recommend to a beginner with the caveat to buy from somewhere where returns aren't an issue

gleaming sorrel
#

Jk

#

I am extremely happy with my Roki. It’s the single best thing I’ve ever bought that improved my images.

#

It’s almost equal to tracking lol. Having come from an F8 camera lens. You could definitely do better untracked with the Roki.

sick ridge
#

I guess I do get caught up in the Roki hate. I've only ever heard of bad Rokis

#

Good Rokis arent talked about

And I mean, 5 min sub.
