just a forum where people can give tips and tricks for the redcat 51
and post there pictures ofcource
Well ill start I guess 😅
Here is mine
great setup!
that aa good one too!
you can also post the pictures you have captured with the readcat 51 or any other variant!
@hardy marsh is that a nema 17 your using as a focus motor ?
Nema14 actually lol, but close! I may downgrade to a nema 8 or something though, as I'd like something lighter and there's no need for it to be high torque
Im trying to get an 11 to work but its being a very bad boy, me and generalsyb trying to get my focuser working for an age and its just not having any of it lol
What focuser did you build? Myfocuserpro2?
No we are using moonlite with an esp32 and tmc2209 driver
Wait, moonlite electronic or manual focuser?
Electronic
What's wrong with it? I assumed it would work out of the box well?
Just moonlite ascom and softwere and my own hardware
Ahhhh I see
And syb's code
Yeah I'd look at a proper diy project like the mfp2
I see what you guys are doing though, and it's awesome!
With moonlite i can run a focuser and a rotator from the same ascom drivers and from the same controller board with 2 diffrent drivers
Yeah we having some issues at the moment
I do actually need to redesign my focuser enclosure and find a way to include a nema8 motor in it 🤔
I keep saying to myself i could releave the pain by getting a zwo eaf but i begrudge giving them my money
So atm im manually focusing the redcat, its easy enough to get into focus
Pinged you out of a thread in diy btw
One thing i did find hard with the redcat is trying to find a 12v dew strap short enough
Like wire or the heater portion?
You could technically shorten the wire by cutting and splicing it back
No the heater portion, seems 12v are all really long for dobs not little refractors
Ive seen lots of 5v usb but not many 12v
I mean, mine is perfect length
The shortest svbony i could find is wrapped 3 times round the cat
i mean, you can talk here. it is about some teqnicals things about the redcat which can help someone.
I would always use one, i had 1 night were i had frost on the main lens so i wont image without one at all now
But even 13" is a bit long, that length we can wrap it around the cat and the guide scope
You have 3 inches of overlap, and that's really it. It's not that big of a deal
Why is mine so long then ?
Is it actually 13"?
It may be 13" whole length inc the velcro strap but only 10" heater ?
Mine is like 20" maybe
Nah, mine is 13" for sure, it has an overlap and I like that there's one, cause I can use the heater on a bigger scope next
Also i have just the normal 12v barrel conextor not the rc thingie
I dont have a peg system
Ah gotcha, well you could technically cut it and put a barrel on it?
There's also adapters
But tbh, a pegasus power box is an incredible accessory to have
Pft lol i had a 5v usb dew strap and i accidently put 12v through it, it made a mess after the buring had stopped
I mean, those are 12v straps?
The first one i had was deffo 5v max
A. About Dew-Not Dew Heaters
Proudly made in the USA by AFAB, the Dew-Not Dew Remover is a thick film dew heater manufactured for operation at 12 volts. Sixty-six percent of the surface area is heat emitting - this means more even heat distribution and no localized hot spots or burnouts often associated with resistance wire heaters.
It's on that page I linked
Lol does it look like it fits? 😂
I'm too lazy, I just have a tarp and padding in a box
I took the original foam out and bought some pillow foam sheet, cut out the shape, put it in the cat bag, now i just take the camera off and off the tracker and it goes in nicely.
I like the cat bag i like to use it
Yeah everything is too connected on mine, plus removing the EFW is a pain, so I just keep everything assembled. As a bonus, takes like 5 mins to setup
I did have to change the dovetail as the original is too small
First Light Optics - Suppliers of Astronomy telescopes, binoculars and accessories from Skywatcher, Celestron, Meade, William Optics, Atik, Imaging Source, Starlight Xpress, ADM, Moonlite, Catseye, Hutech and others.
This is what i have now
Yeah I was looking at that one for a bit, but didn't feel the need for extra holes tbh
Most of my cables are all down the middle
Or didnt feel the need to spend nearly £100 on dovetail ?
That too lol
Hello!!!
@slow gull
huh
Takes excellent photos at airports with their redcat 51
I didnt finish but yeah
||the pictures aren't good though lmao||
I think they're fine though
well, thats a good photo, it is really noisy, but still good.
was that of the coment ef2022??
Ye
Here's my best shot with it
Ooh that’s good!
Seems like my forum is running dry
Why u say that ?
Nwm
Captured this with my cat on sunday night whirlpool galaxy
Oh, good to know you can even capture some galaxy’s with the cat
Andromeda with the cat
The 51 only has a FL of 250 so realy far DSOs have to be zoom cropped but widefield its brilliant, mine is paired with a asi533mc pro which is a good combo
I bet if i targeted say m86 i could prob get hundreds of galaxys in 1 picture
You know this weekend i might just do it
Asuming i get clear skys
Man, galaxy clusters might be my favourite to capture man. Just to know that you captured thousands of galaxy’s with wacht more then 200 billion stars and planets!
Yey, my forum reached 100 replies!
Well the whirlpool galaxy i posted has an estimated 100billion stars
Well, I might have exagerated a bit.
No no some have way more
Like the m86 galaxy right?
Not sure, i think our galaxy has an estamated 500billion stars
UGC 2885, HOLY, it has a trillion stars!!!!
Yup there you go
Man, how have we been not visited by some curious aliens? I mean. Ok I get you may be not interested in us, but we are even untested by ants.
I mean intrested
I have a theory that is also supported by Brian Cox
And what is that theory. I would like to know
We as us humans are not that advanced, but our galaxy is one of the oldest in the known universe, we are 13.6 billion years old, and the known universe is 13.7 billion years old so in theory only galaxys older than us would have inteligent life able to visit us or comunicate with us, assuming younger galaxys dont have rapid ageing, so yeah this cuts down the amount of possible galaxys, now people will disagree and have theorys but thats ok thats what we are here to figure out right 🙂
But the kicker is earth is only 4.5billion years old which in the universe terms is not old at all, so although our galaxy is old the earth isnt, but then how long would an inhabitable planet take to produce life, again its all theory, nothing proven, nothing disproven all guesses at the moment
Well, I may sound lunatics but I have a little theory that I thaught of if you want to hear it.
Go for it
Im getting one soon

And "soon" being I'm 14 and I have to wait 1 year for me to get the $$$ for it. I can't get a job nor debit caard. Because my parents wont allow me. But still 1 year goes by in an blink.
Well, how I always think how the time in percentages. Now, 1 year of your life while you are let’s say,5, that’s 20%!!!! Of your whole life, while let’s say when you are 100 years old, you get a year older, and now that was only one percent of your life. So while for the 5 year old, one year took a reaaaalllllly long time, once your even 30 or 25. One year does not seem like much.
Well that’s how I think
So the older you get, the faster life goes!!
Hava a word !!!
you found ALIENS
I found elon playing tic-tac-toe in the sky !!!
hahaha, he seems like so
elon just wanted to play with his aliens friends
wanna go?
I got X you got O
oh my gotttttttt, tic tac toe in SPACE.
Oh no, caphe is going to win. What will lozandogg do
AND lozanddog has has placed a counter attack, what will caphe do now
TUNE IN TOMMOROW MÖRING TO SEE WHAT HAPPEND
Seems like nobody is using this forum to post redcat 51 things😢
seems like so astrobeginner.
idiot
jk, that account is just my phone accoutn
Indeed I can confirm
@bleak girder well that picture was taken on my cat51
well, yes ofcource.
but there is a plot twist coming
now defeat this MOEHAHAHAHAHA
No plot twist that was from saturday night with my redcat51 of pinwheel galaxy that was a 120s sub, i managed 7.5hrs of intergrated moon washout !!!
7,5 hours wow
but this was the plot twist
i was talking about
i addded my own tic tac toe
And yeah hours of starlink satalite interuptions as well
@bleak girder i concede you win the elon tic-tac-toe game
@shut comet when ever i image i normaly start at about 9pm and leave it running till 5am, i leave my rig in the garden and go to bed, callibrations are done in the morning when i wake up
ah, so it is self automated. i still have to do everything manually
@shut comet even manages its meridian flip on its own
I use nina, but just the simple sequencer, i havent set up and advanced stuff.
oh wow. i have a dslr and a mechanical star tracker so there isn't really to automate in my case
I used to use a dslr and star tracker and still be automated, just not for so long still 4-5 hours tho, when you say mechanical star tracker ?
the omegon lx3
it needs to be rewinded every 1 hour
@shut comet like a clock ? I guess thats one way of not worrying about power issues
yes. littaraly haha.
but the main reason is that it was cheap
or else i would have gone for the star adventurer any day
its thousand times better
@shut comet i have a swsa 2i that i was using and yeah its great, now i have a swsa gti and i love it also
thought you were gonna get away with that little move didnt ya
oh no, this game will end in a draw if lozanddog is slim
EYYYYYY LOZANDDOG, your a red dwarf!!!!!
Oh hang on a min, were is the other line, is it at the bottom ?
you just gotta imagine it
Uhm lozandog, it’s your play
Im going for the win
Redcat 51 TicTacToe club
not so fast
The galaxy sent some aliens in
^
🤨
Agahaggaggaga ALIENS HAVE COME
What
hey people
lozandog,
its your move my man
and caphe
what lens would be good with a nikon for wild life photography
since you have got some great images.
@ember fulcrum
what's your budget
about 500 for a lens
tripod i already got
and a dslr
i heard zoomlenses are great, but also that prime lenses are sharper
a used sigma 150-500
prime lenses will technically be better than zoom lenses but both are just for two different purposes, zoom lenses are typically preferred for wild life
because you could zoom in and out depending where the wildlife is.
yea
you would really enjoy the 150-500
what lens mount is your nikon @shut comet
F?
lens mount?
wait, dx?? does that help/
how do you not know what a lens mount is
no
Srry, I mean f mount
Nikon D7000
nikon F 150-500 in perfect working condition for $385
What lens do you currently use?
samyang 135mm f2
Its a great lens made for daytime and portraits
My setup and a bad picture of Orion I took after first getting it (took with no guide scope, no tracking from my deck)
Could be far better when you really maximise your setup. You have a great and capable setup
Thank you, getting my AA+ today, so my whole setup will hopefully get easier and faster to setup. The biggest barrier to using it, was the setup and use...PHD2 etc is very frustrating to deal with, especially when you need a laptop to control the mount + guide, and a tablet to control the camera lol
Ah ok, I hear NINA helps a lot and eases things a lot too
Image I captured last night, processing with Siril, and I am pretty bad at it.
Ggs bois.
💀💀
Here are my shots so far with the redcat, I think I’ve been using it a bit wrong so all of them are a bit out of focus
Sure lol
Hot
Here's a recent picture I got
So sharp 
sheesh
Yeah plane spotting has been awesome since I got mine
some of them have trailing noise. but still good images
Yeah I don’t really have a way to fix that rn
Most of those have like 3 hours of exposure besides rosette
Should I use that same image you guys were playing with before?
yea, or you can make your own image
you are going to have to wait atleast 1 hour before i make my move, this has to be precise.
Please clean your sensor
It doesn’t come off aaaaa
I’ve tried cleaning it like 5 times
Also here’s my rc51 setup
(Please ignore the white 3d printed parts)
I like the wire holder
Thanks
Those ones are custom made, pretty simple design but they don’t work super well
I might re design them and print in black
oh you're a good one,
still cant find the stratagy
WAIT I FOUND IT
HAHAHAHA
ONLY TOOK MT LIKE 19 HOURS OF PLANNING
HAHA
uhm.... where are you?
i mean. i spent 19 hours on planning my moves my man.
Still thinking 
I have made my move
I have stayed up… THE WHOLE NIGHT. Just for my perfect move MOEHAHAHHAHA
Hah, and I stayed up…. The whole DAY to perfect this precise and well planned move to block you
HAHAHAHHAHAHAHHAA, I KNEW MY PLAN THAT I WORKED ON DAY AND NIGHT WORKED!!!!!
Well, lemme draw the situation out
@ember fulcrum
Do you want to change you mind?
no just let him make his move
@drifting scroll RAIDERREEERRRR.come forth if thy dare.
alright, i will give you some time.
Hah! Well you can’t beat the square! (I forfeit)
MOEHAHAHAHAHA,
AND SINCE YOU FORFEIT,
I WIN
GGs btw!
GGs
Omg you guys play that incredably fast !!
Hm, seems like more people should join our club
💀
Yea, you…. Up for a game of tic tac toe?
💀💀
@slow gull
No thanks
How do you guys put on the wo bahtinov mask, everytime I do it i fear for my fokus… and if I take it off the same thing doesn‘t it shift the fokus?
The redcat 51 has a second ring that when you tighten also tightens your focus so that when you move your redcat. The focus stays the same.
Yeah it should work when you twist the lens hood, there should be some words saying “focuser tension” and if you hold the back of the scope while twisting it towards the direction the arrow is pointing, then it should tighten down the focus
yeah, I tested it but the focus shifted, even though I tightened that second ring pretty good…
(I have the v1.5 so maybe its because of that)
@bleak girder i also have the 1.5 and i find the dew shild tension on the focus works quite well, one thing i also do is when in focus check the focus mark, if u do accidently move it you know roughly were it should be, do a test sub to check, i used the focus markings for ages knowing it was the correct focus.
CHEAPCAT FOR LIFE
lol what is this
Wdym it’s the tic-tac-toe club only for redcat users
It’s like a perk you unlock if you get one yk
Definitely William Optics certified
might have to get a redcat
You should, then you can play tic-tac-toe with us
(It’s also a great and versatile scope that is equipped to handle wide field and deep space photography, especially if you have a crop sensor and or a autofocuser)
But the tic-tac-toe is better tbh
yup.
💀
💀
How is this RC related?
I took the original tic tac toe board with a redcat 51 and it had so many satallites in it that it made a tic tac toe board
well, the name now indeed it redcat AND tic tac toe club.
you wanna play tic tac toe?
i'll begin
weather is broken at my location, 6 weeks no clear night
so no🥲
It’s been broken for me, but possibly may clear up Wednesday…
I have a “pre” pic - just need a “post”
Yup I got it
Single sub unstretched
Love my redcat but galaxy season has been rough 
Same
Woahh that detail on m51 is nice
Tks! Yeah that was from a Bortle 4 “dark” site, whereas the m101 was from my Bortle 7 front yard
@drifting scroll got it!
Nice shot!
A surprising amount of detail too, any blurX or anything?
Yup, BlurX and DeepSNR
DeepSNR does a lot better job on galaxies with lots of tiny details, but makes it look a little like it has miliary tuberculosis. I’ll work on this some more later to help it be less mottled, hopefully.
Lol, I would get deepsnr but I can’t afford to get pixinsight atm
I resisted a very long time, and got some pretty good results with Siril. It’s worth it, though. I suggest doing the 45 day free trial, and do the free trial of BlurX simultaneously. DeepSNR is free, but complicated. Only works on CFA drizzled x1 data if using an OSC camera.
yeah
Nice
what
y'all wanna play tic tac toe?
holy
this is the space sheet everybody will play on
YOO
Meet the Cat !!
WOoo shes a beauty......
That is beautiful man, wow
And very expensive XD, but the images seem to be worth it
Yes totally worth it
Clean rig 
Time to wake this thread from its grave
Low left corner
I always worry about the wires maybe causing drag, i managed to get mine down to 2 wires coming off the scope, 1 is the usb to the mount, the 2nd is the 12v, i have plans to even remove the 12v as well, so no cables are from the mount to the floor
Cables have got tidyer since these were taken
Hmmm upper left corner
Hmmm, the next step will be hard for me, I shall think till morning
(Real reason, need to go to sleep)
hi! i’m ordering the redcat 51 tomorrow!!
guys will i still be able to use the same spacers i use with my zs61 for my camera ?
it’s those
They should work as long as they are m42 mount
yeah okay cheers
I made an underbarrel grenade launcher for my redcat 
I really should mount stuff like a normal person
Ive seen guide scopes hung underneath, keeps the CofG low
Good idea!
Fully loaded Redcat !!
bootiful
yeah take the whole red thing off
and flip it to be the other way and screw it on
I was confused when I first used a redcat, too
Really rudimentary precision focuser for the redcat since twisting it normally isn’t all that accurate
I really need to improve on the tolerances tho
what you need is autofocusing, really the redcat is meant for longer integrations and to get good quality you need to adjust focus from to time to time to account for temparature changes, plus autofocus is always more precise that you can ever be manually
Yeah I know I need it, it’s next on my list. I just got autoguiding but currently autofocus is too out of my budget, maybe in a few months
💀
instagram now
no
Nice worm gear
Dayuüm
@drifting scroll dude dont panic about auto focusing yet, i was using my cat well over a year with no autofocus, just get a lens heater band, as long as you can keep the cat lens warm there wont be a noticable change in focus, as said i used a batonov mask to get focus locked down the lens hood so the helical focuser didnt move recorded the focus setting and didnt change it for a year until i did buy a focuser, and you know what even with an auto focuser i still cant see a differance between auto focus and my focus !!!
Ah ok, I don’t have a heater band (because I live in Hawaii, where there is literally no dew) but I’ll look into getting one. It would make sense to keep it at a stable temp throughout the night and is probably part of what’s making my images all messed up. Thanks for the insight!
The idiotic felt that's in the cap is mad annoying
Have the same issue with my z61
yeah it’s so annoying there’s so much
i might rip it off honestly
i did on my zs61
Well it won't hold at all likely
look for one and u dont gotta worry bout the filter since it has a holder
DO NOT TIGHTEN THE THREAD HERE TOO MUCH
you will have to use pliers to unscrew it and youre filter will be stuck
i cant even get the threads on
Serious question for once: How do I get rid of astigmatism on the redcat? (pinched optics) @inner oracle
No idea, sorry. I don’t think g you should get much distortion overall, unless you get to the outer edges of the image circle
RedCat 51 on AM5
hot as heck

Red cat looks like my solar scope
Do your stars look like this too? Cause they seem to look like a pentagon to me…
Aussie dollars
ohhh
found out that the star shape is actually caused by the sensor.
Is there also a redcat61 thread?
Made an ultra slim mount for my guidescope, hopefully I can test it out tonight. I still need to print a focuser that’s lower down tho
I need to spray paint it too
yk that white thing around the focuser , is that needed ?
For my focuser machinist to work yes, but a stock redcat doesn’t meet it, it just helps because I find it inaccurate to twist the focuser back and fourth
ahh ok , i got mine form FirstLightOptics so idk
this is what my setup might look like in 2025
Same except an AM3 and 2026
First ever image with my redcat 51, just a test image only 5mins of data with the almost full moon out
nice , if you haven’t already i advise purchasing a UV/IR cut filter
It looks like he already has one from the looks of the stars, or he's using a DSLR which already has a UV/IR cut.
I also got 1 sub of Horsehead lol
really? stars look good but they have no colour
narrowband lol
ahhhh
okay i see
kinda forgot that narrowband causes that , literally got everything to image narrowband but clear nights have been rare
my bad.
nebula looks very good tho
Hey, so I recently just got the redcat 51 for Christmas I was wondering how do I mount the guide scope that comes with it to the telescope itself? Without getting a $70 piece of metal
You don’t

That is unless you have a 3d printer or access to one
So something like this would not work?
Yeah that would work just fine
Do you know the thread sizes on this area of the scope?
Sorry I kinda mislead you lol I just found it funny WO didn’t include the mount
M3 and M4
Are they supposed to?
No I don’t believe so
Ah
So which ones are M4 and M3
M3 Are the smaller ones M4 are the larger ones
You probably just need the M3 tho
Or just the M4
No need for both
OK, so basically, I would just look up this mounting bracket with the correct screws?
Well that mounting bracket claims to be universal, so it should work with the redcat but there’s no way to be sure unless you just buy it and test it out
OK cool
I just really did not want to spend $70 on a piece of aluminum
Maybe in the future but right now I’m trying to save money
WO moment
Idk why they overprice their parts so much I made an extension rod for my mount for like $2 out of aluminum with a near mirror finish that’s $30 on their website
With a desktop lathe too
Dang
I just find it so stupid why they have some pretty good deals on glass but when it comes to metal they just overprice it by over 3x of what the stock probably costed then
Because their stuff is pretty much, the only stuff that will fit with their stuff
If that makes any sense
Dimension wise, will this fit
I would be placing my screws on the center vertical cut out
I’m just not sure if 20 mm is enough gap
Hmmm
So you would be putting it in that cross area and the head of an m3 bolt is about 5mm
I think that should work then
Wait can you flip the picture so it’s top down?
Yeah that’ll work
That gap in the middle seems to be enough to catch the head of an M3 screw while letting the threads through
Since it does not come with M3/M4 screws, do you by any chance know which ones I need
Wait lemme check mine rq
That’s an M3 thumb screw
Yay finally after two hours. I’m getting somewhere with this.
So I’m gonna have to buy the screws third-party I know I’m asking a lot of questions, but do you know what length I need?
Normally they come in a pack of assorted screws, but I’d say about 10mm should do it
OK yeah I can check and see what it comes with but if not, I should be looking for a M3 10 mm screw correct?
Yes but I highly recommend you get an assorted pack bc I’m not entirely sure if 10mm will be enough
OK bet
They normally are just like 10 bucks or less
This looks perfect size
Because the screw, I tried did not go in super deep
It probably went in half
Do you live in civilization
Yes?
Yeah, this is true but I’m currently just trying to find what I need
TBH I may already have some
@drifting scroll OK I went ahead and bought it. Hopefully we are right.
highly recommend to get the WO guidescope saddle
agreed
Yeah, but I’m kind of broke
And I found a $20 solution
hope it works out!
I don’t really see why it wouldn’t
I will eventually get the saddle in the future. It’s just right now I’m trying to budget.
buy once cry once
Don’t spend $70 on a piece of metal don’t cry ever
It feels like 30 or 40 maybe but it’s way too overpriced. In my opinion.
Yeah, but this will do just as good
But I do plan on eventually getting it i’m just trying to get everything generally set up and in testing
Very nice! You’re lucky you found them at the hardware store
Macro redcat goes hard
this is amazing!
These are so pretty WHAT
Literally looks like it came from an animation, I love these
really cool work
thank you guys 
first light on rosette with the RedCat51 , 75 mins guided b7 L enhance
re process
Hey I need some help I would like to do lunar and solar photography with the red cat 51 but I need more FL do they make Barlows for it?
26 3 minute subs on flaming star , you know the scope , uranus c pro , L enhance , guiding and sky watcher star adventurer GTI
No, they don't make barlows for it 
That is not the purpose of the scope
Figured
You don't need them to do solar or lunar
It's sharp to do decent pics, even with the low fl
Yeah, I need to try it then
currently at 22h on this project, probably gonna wrap it up soon but it's stupid noisy and I have no clue why
also that's a super rough process and it was shot with my XSI
i think you answered your own question 
Why tho? I’ve gotten clean shots with my XSI before and even the thoroughly processed image still has lots of noise
This some faint dust
would the rc51 be suitable to image the 100% eclipse coming up on april 8th
I would think so if you had a good solar filter
Captured with the red at
Hey guys, what's the best RC51? There is like 7 versions of it
they're all the same, except the newer version you can't use for visual
Why not?
You need the erecting prism which is “coming soon”
Like a diagonal?
all my images so far with my redcat 51
My recent stuff all shot with a Redcat 51 and Ares C Pro
Runjing chicken is HaRGB rest is pure broadband
Dead forum 
yea the host gor bannend
he dind't even have redcat lol
tbh this server is slowly dying too
Oof
Not really
it is alot less active then 2 years ago
