Faststar/Hyperstar: Is it worth it at this price?

6 posts in this topic

I was looking at the Hyperstar/Faststar mod for my 9.25 SCT.

I nearly fell out of my tree when I saw the price at around £1100!!!!

That is more than the cost of the OTA by a long way. Just wondering:

 

1. Is it worth it

2. How Celestron justify the eye water and nether region cringing price?

Don't know if you can justify the price but I think the big problem with it is fiddling around with filters and focusing, bit of a gimmick IMHO.

A Tak Epsilon may be slightly less trouble if you wanted a "fast" imaging scope.

You may want to search Astrobin or other image sites for examples of the results. I know the huge increase in field of view is appealing. That much light gathering over a wide area...

1) Can be if you like the faff

 

2) Can you make your own?

 

No other option really if you want to operate your SCT at F2.  A .33 focal reducer will get you close with a CCD.    :icon_biggrin:

1. No

2. Because they can / lack of production scale to bring costs down

Focusing at such short FL will be extremely tricky and you will rapidly get frustrated. Rest assured.  Olly will be on soon to tell you the same I am sure.

It is a tick in a box to say the scope is "DSO AP ready".  I am not slagging off the C925, I have one myself and it is a superb scope.  It is not a scope for deep Sky AP though.  It is a planetary AP scope.

For the £1100 you spend on that you could get a HEQ5/ED80 + DSLR and do AP properly.

Just my 2 penneth

Imaging at f/2 does sound very appealing, but if it sounds too good to be true, it usually is.

F/2 requires very tight mechanical tolerances, zero component slop and a very rigid telescope structure. Having owned a Celestron SCT myself I

think this will always be very tricky...
