Hyperstar with gso 8 inch

[xelasnave]

I have been looking into hyperstar imaging I suppose prompted somewhat by Davids new scope purchase as up to now I really had not considered the system.

I would love an 11 inch but its probably just a little too big for me to manage because I simply am not as strong as I once was.

My question is what do you all think about using a gso 8 inch with a hyperstar instaled ( not the f5 ).

If its viable I would get a cooled colour camera for it rather than use a dslr which probably wont work for 8 inch.

I have had a quick look on the net but have not found anyone using such but I expect someone has done it.

Any guidence will be greatly appreciated.

I have been planning to get a skywatcher 100 mm but before I get one feel investigating the hyperstar may see me change my mind.

The speed and large app. appeal and I enjoy rather wide fields of view which seems to be what hyperstar could deliver..

I understand focus is a problem but it always has been for me so maybe I will be able to manage any frustration in that area.

I am thinking it should be a satisfying set up.
Any views on using a gso 8 inch?

Hyperstars (Fastar) are only for Celestron SCT and older Meade models.

Not going to work Alex - you'd need to design a corrector lens specific to the scope. Remember, the Celestrons and Meades that use it are SCT's so have a corrector plate up front.

You could do it, but NOT with a stock unit.

Thank you OIC and thank you Lewis....

So that takes me forward as I was not aware it was limited to celestron or meade.

Thank you very much ...still I can handle celestron or meade...my first scope was a mead and my second a celestron...I just thought GSO had superior optics
So a celestron 8 inch or a meade?
Any negatives on the idea?

It is more the telescope designs that stop you from being able to use it with a GSO. The hyperstar is designed for the ~F/2.2 primary mirror within a SCT. A GSO, whether F/4, F/5 or F/6 has an entirely different field curvature that the hyperstar will not be able to correct for.

Thank you Colin.
Please what is your view on getting say the celestron and hyperstar fastar ...

I’d say that there are a lot of happy customers with it
They do have their difficulties from what I’ve read but I’ve never used one.

Hi Alex, there is a lot of info about hyperstar setups on cloudy nights. Using hyperstar for EAA (near real time) and “proper” imaging.

I have been tempted by it or ages....but for eaa.

Ps I really enjoy reading the threads you start! Your candidness about your progress is refreshing and keeps things very real and in perpspective for me.

Thank you for your reply Colin.
Thank you for your input Hemi and your kind words.

Alex, the newer Hyperstar are exclusively Celestron. There exists Hyperstar for OLDER Meades, but not for the newer models.

If you are going the route, then you have two varieties of Celestron. Classic or HD Edge. They are different, so you have to match the optics to the Hyperstar.

I read somewhere that Meade was not interested in talking to Starizona re: the new Meade design, so Hyperstars are no longer manufactured for them.

If you are going toward imaging only at f/2+, then getting a RASA would be a good choice... someone on these forums recently got one!

OIC!

Hi Alex

I been researching similar setups. From what I have found out instead of a RC 8, I would get a Celestron C9.25 SCT for which you could then get the correct Hyperstar adapter. If that scope is too big then the EdgeHD 8 would be an option, but you would need to get the appropriate conversion kit to be able to use Hyperstar.
