Hey friends!I need your help.What do you think about the Sharpstar 76EDPH telescope paired with the ZWO ASI 533MC cooled color camera?I have an EQM-35 mount, a SV165 30mm guide scope, and an ASIAIR Pro.I'm a little bit low on budget
doubts about telescope and cooled camera for dso
Sounds like you have most of what you need, go for it. The mount is near it's limit but it should work.
Someone told me that telescope is better
But i not find any video or information about it:
TS-Optics CF-APO 70 mm
Also he told me that the Sharpstar 76ed have a shapness problems and aberrations problems..

I have no idea, both should be capable scopes. I would think that sensor size would have a lot to do with it. The bigger the chip the greater the demands on performance.
So you'll spend $799 (current sale price Agena) on the scope and another $200 on a field flattener. I only saw a .8 reducer, but I guess there is a 1X flattener for the scope. So at that, you are in $1000 for the scope. Now this is just my logic, but I would go for a Redcat51 III WIFD at less money and you're not dealing with backfocus. The RedCat51 is a fast scope at f/4.7 and your FOV is going to be larger than with the Sharpstar, even with it reduced by .8. The Sharpstar will be around f/4.4 when reduced. The RedCat is a perfect weight for your mount and it's only $898. The hardware and finish is top notch. The RedCat also comes with a camera tilt adjuster that can be adjusted without pulling the camera off like the ZWO CT adjuster. With the money you save, you can throw in a filter drawer. The RedCat has a spot for filters, but you have to disassemble the train if you want to change it. That's a no go for me, so I added a 5 position 2" filter wheel with various Optolong multi-narrowband filters.

*** Thank you for your advice i didnt knew that there is a telescope that no need the reducer.
I will add the redcat telescope to my list and do some research about it btw the problem is the redcat is only 250mm focal len.. .. thank you man!

All of the Petzval design scopes are flat by their 4 lens design. I do so enjoy buying telescope gear, and researching to arrive at pulling the trigger is half the fun. Good luck!
EDIT: I don't know if you are familiar with Telescopius. com but you can plug in your scope , camera and reducer info and get a good idea about what field of view you will have with any given combinations of scope/camera/reducer.

All the necessary was answered above, in your situation/budget I would 100% take the redcat too.
Just an advice on your research you will have a narrow FOV due to your sensor anyway.
so just remember this equation and it's even more valid with small pixels:
Troubles= Focal²
enjoy the process of choosing your scope that's as enjoyable as using it haha

*** Thank you very much i am appreciate your help!
Everything* in my gallery was shot with a 533mc pro and the red cat 51. It's a really great setup and there's lots of targets you can capture with this scope and camera setup. If $1000ish is your budget, you can get a filter drawer and a filter too if you want or need one. The Antlia Tri-Band has been great for me with moderately light polluted skies. It's simple to use and the wide field is very forgiving. You'll enjoy that setup for a long time!

The longer (bigger) scope will demand a bigger mount due to tracking accuracy and play-load limits. The image quality from this tiny telescope exceeds my expectations in many ways. I own 2 very expensive Takahashi scopes, but more than often I've found myself enjoying the RecCat51 more than the Taks.
The RedCat is a perfect weight for your mount and it's only $898.
I hope I'm not breaking any rules by sharing this on here, but there are actually a few discount codes available for the William Optics Redcats that can bring their price down even lower: for example, the code ASTRONOMICAL should give $100 off all of the Redcat line scopes if you purchase directly from the WO website. This could potentially bring down the cost of the Redcat III to $798, saving you around 10%.
Hope this info is helpful - also, just a disclaimer, I am not advertising for William Optics here, I just randomly came across some of these codes when I was looking to buy a telescope from them a while back, and while I didn't end up using them, I thought might useful for other people looking to save some money.

I agree.
If you absolutely need more focal length, there are the more expensive Redcat 61 and Redcat 71 models at 300mm and 350mm respectively.
Well Written Concise
I'm going to have to agree with everyone on the Redcat51 and it design… the fact that you won't need to deal with a flattener is a plus in weight and scope cost… My first scope was the WO Z73.. this was just before the Redcat 51 came out.. I now own both, and if I had a choice between the two at the time, I would have given up the longer focal length for the simplicty of the Redcat51… I'm actually thinking of trying to sell the Z73 and replacing it with the Redcat71

Hey friends!I need your help.What do you think about the Sharpstar 76EDPH telescope paired with the ZWO ASI 533MC cooled color camera?I have an EQM-35 mount, a SV165 30mm guide scope, and an ASIAIR Pro.I'm a little bit low on budget
I have a sky watcher 72ed and svbony version of your camera.
Only been doing this for 7 months, but my gear is far more capable than I am, still.

The evolux range suffer of some chromatic aberation unfortunately, and it's a bit of a gamble to get a good copy.
Some people in our club got some based on youtube reviews and the blue correction is horrendous.
Great scope to start with but you will reach limitation in the future

72ed is part of the even less premium evostar range. Apart from that I agree with everything you said.
Hopefully using narrowband will counter it's issues a bit.
Cooling Temperature
Hello, I have an ZWO ASI 533MC, what temperature do you use generally to cool the camera ? thanks William
