Here is a link to a thread where I attempted to image a medium sized galaxy with a RASA8 and a small pixel CMOS camera, and compared the results with a 1050mm FL 6” APO. The RASA came second.
wow, very impressive!

Each to their own, but I wouldn't touch a Hyperstar with a ten foot pole. If you read enough owner accounts, and look at their results, a pattern emerges: a few people get decent results, most don't. I agree absolutely with your earlier point, though, that a RASA should be bought only from a very reputable dealer with good returns policy.
Nothing like enough FL. The RASA is a widefield instrument, pure and simple.

That is a bummer... I was hoping this can image Saturn....
Maybe I should start with a C8 first? I actually ordered a C8 from Amazon when it was on sale a few days ago ( ~$1150). Many people said Rasa is much better, and I do like the fact that Rasa is a F2 - but if it can not image something like saturn maybe I will get start with the C8 first.

Personally I'd err caution and only buy one from a retailer with a good returns policy or from an individual whom can prove it's imaging condition. It's a scope I'd like but I've been put off because of this issue, and I can't mount a larger one which are unaffected as far as I'm aware.
Thanks for reminding. It should be from an authorized dealer with 30 days return policy. I will double check.

Have you actually paid for it?
I'd be a bit cautious at the moment as last year most retailers stopped selling the 8 inch due to a manufacturing quality concern and stock was returned to Celestron I believe. It doesn't affect all scopes but I'd be dubious of any available on the market at the moment, as good as the scope is.
Not yet - Greentoe says order was planced ( offer accepted) - but they have not charged the card yet. Thanks for this important information. It is indeed a bit suspicious, thus I am asking around here. I bought a couple of time from Greentoe before but usualy buyers need to send individual offers. I was a bit surprised to see $1535 price pop up just in the google search.

Thank you very much for the information! I will check out the camera and mount you mentioned. Will definitely looking into the tilt issue as well.
Another naive question: I know Rasa is for deep sky, but can it still produce good images for jupiter-like planets? Maybe not enough focus lengh?

And I am in Arizona so the sky is mostly clear. Thank you very much in advance for your help!

I new to astrophotography but I have been using Nikon for ~20 years with numerous cemaras and leans from 14mm to 600mm. I bought lenses from greentoe before and they seems to be ok. But not sure with something like Rasa 8. I would also need get a mount and a cemera. Would really appreciate it if I can get some advice on these items.

Hello everyone!
New to this forum and need some of your advice.
I just bought a Rasa 8 from greenteo, ~$1500. First question, has anyone bought astroimaging equipment from them before?

Looks C8 is an easier option for me now - kids can directly start looking into it. Thanks again for all the information.
