Celestron Nextsar 102GT (F10)

Post by dazcaz »

I see that Costco are selling the Celestron 102GT (1000mm F10 version) for 155 quid.

Anyone tried one of these?

The reason I ask is that I'm becoming a "ask Darren he'll know what telescope to buy" sort of person.
Neighbours and friends come and ask me what to buy for not a lot of money.
I point them to websites and they come back which options and can't make decisions.
Is the above 'scope one that I should recommend for a beginner?

I have a 4" Celestron C4-R refractor on a manual (CG-4) mount and I love it, and others who have looked through it are very impressed.
Will the above 'scope be equally impressive?

I like the fact that it's an easy (so they say on the box) set up GOTO.
It's a 4" and the lump of glass on the front looks decent enough.
It doesn't look as "professional" as my C4-R but that might just be me being slightly biased :)

Before I go adding this to my list of recommended 'scopes, I thought that I would ask you guys.

Opinions welcomed.

Can't give any personal experiences with this 'scope, but look here for info:

Second one is US based but it's the same 'scope.

Thanks,
I had read these but they don't really go into how decent the scope is.
the one review that does go into a bit of detail is typed by someone who doesn't have a return key and is very hard to read :)
I think he gives a good review.
I'd rather someone on here who can type give a report. :)

I'm tempted to get one just for the goto mount. It's no great, but if it would hold my Skymax 127 Mak then it might be worth it.
My mak lives in the motorhome as a "grab N go" a goto mount would make this even better.

I will add it to my "try one of these" list. For the money, it's better than a cheaper rubbish scope... At least it should be :)

I think the main concern voiced about the f10 OTA is that it might be a bit too long for the mounting to carry comfortably - wobbles while focusing etc. I've got a 102mm f5 OTA (Helios) on EQ1 and I'm happy with the optical quality for what I paid. The f10 should be better wrt chromatic aberration.


As you say, it's probably a good way the get the mounting to use with other OTAs. Not sure if this would mean using different dovetail bars for other OTAs?
