This scope good for EAA ?

[barkingsteve]

As usual, i am getting  speed fever. This scope seems like it would be ideal for EAA and would nicely fit on my evolution mount. Could this be my dream scope ?

Any thoughts or observations appreciated, was thinking about the hyperstar but this is 4kg less than the 925 which is great for better stability.

Should do well as you at only using a small sensor.’stability and collimation could be issues. Will really brighten up the nebulae!

Well my F/3.3 Takahashi Epsilon (130mm) sucked up enough light to show the Cygnus nebulae very clearly from central London this evening - superfast scopes work well with a 3nm ha filter and night vision equipment. So the Sharpstar looks very interesting for EAA. Must be a tricky telescope to produce. They have a good reputation as a manufacturer of apo refractors, but haven’t seen more specialist imaging scopes like this before.

Found a review of it on cn forums. seems solid enough

thanks for the feedback guys. I am leaning towards a 'yes' when funds allow  and the colour scheme  will fit nicely with my 294mc pro, just need to respray the rings on the evo mount red now hehe.

Edit: looks like they do an 8" F/3.2  version, would be a tight fit on an evo mount though 😕

Good luck - and do report back if you get one Steve. I believe Sharpstar is a relatively small and specialist operation, unlike more mainstream Chinese suppliers. So maybe more interesting products to come.

After following the cn thread about this scope, seems like there are a few problems with it. While i would love a scope like this i am not really a tinkerer and for that price i should not have to be spraying nuts black and replacing screws with nylon tipped ones 😕   My original plan was to upgrade from a 130 pds  f/5  to a 150mm f/4, only a slight improvement but improvement never the less. Alternatively i could go carbon fibre and possibly squeeze an 8" f/4 on my evo mount but not sure the extra 2" aperture would be that much of an improvement for an extra £500.
