Well boys thats exactly what I am doing, having a little fun. Everytime a thread comes up about the GSO RC's three things always occur.

1. The focuser: just change the bloody thing and be done with it.
2. reflections: Show me a system totally free of reflections on any object and I will bite myself on the bum. This has been largely fixed (not totally as it is not possible) in the new GSO tube.
3. What about newts? What about the price to properly mount a newt to get good images let alone fitting the thing in a car.

Seems to me people are all too keen to trash these scopes (and it's a good one) with no real reason. I could just as easily say AP scopes are crap because they don't come in dayglow orange and golly I would have to paint it myself .

And Mick I am not saying it can't be done just that it is not really practical when there are other easier options available.

Thank everyone for the feedback and as I have now purchased the GSO 10" RC I think this thread is now redundant.

Frank,

congratulations on your purchase of this fine scope. Please let me know if you have any questions relating when you start imaging with the scope.

Trevor, thanks for the kind words.

Paul,

Thanks for the offer of help and I will certainly take it up as needed,

Collimation will be the first issue and I will need a clear night for that to happen. It actually looks pretty easy from what I have read on the web. (famous last words).

Frank

With you there totally Mark (dont know why you cranky about it though ). A big long newt on a dodgy mount (of the same same apature) looses any price advantage it has over the RC , "guiding is paramount" (sorry, I didnt mean an obscure reference). Small newt, fine, but a 10" newt?, nah, a 10" GSO RC with a better focuser and some fiddling, even at a higher price would beat it hands down *for long exposure imaging* just on guiding alone (from what pics I see and hear).

The trashing of GSO RCs comes from expectations of the magical "RC" tag and comparisons with other RCs, which are all vastly more expensive, and ignoring the stupid price. OK the problems are unfortunate, but relatively irrelavent given the result possible.

I bet you do Fred and I don't even own one of these scopes!

Congrat's Frank I am sure you will love the scope to death. They are not difficult to collimate and have nice sharp views and are very well finished if TrevorW's scope is anything to go by. With a good moonlite or feather touch attached you can't go wrong.

I just read on Cloudy Nights forums that Astrotech are releasing a 10" version with Carbon Fiber tube and a 3" Feathertouch at NEAF this year... It will be available through Astronomics and Optcorp.

If that doesnt silence the nay sayers I dont know what will..

Ps. Estimated price tag (From the owner of Astro-Tech) is $3900USD with CF tube and 3" FT.

What was that saying again? You get what you pay for??

Hi All,

As there seemed to be some interest in the Newt vs RC comparison, I got a sub from Bratislav and one of mine taken a few days apart. I started a new thread. Remember this is for those of us that are genuinely interested in these things, NOT a pissing contest.

Collimation

Hi Frank Sorry for the delay in replying.

I did a Google search and found this document on the Astronomics web site regarding the AstroTech 8"RC and figured it also applied to the 10" RC.

I just used it as a guide and it ended up being a fairly simple process.
Here is the link.

Also congratulations on your fine purchase. to the club.

Cheers,
Luke

Luke,

Thanks for the heads up on collimation.

I'll give it a go when the nights clear. This has been another 4 day weekend and not a star to be seen.

Of course it is back to work tomorrow and there is not a cloud in the sky today.

Roll on the new weekend and clear skies.

Frank

I'm still working on it, but this is how I do it...

Simple on axis collimation is easy, removal of the tilt is difficult but doable.
Good luck.

Trevor,

Don't worry, I will not be doing that. Hopefully I won't have to touch the ones on the secondary!

Why? Initially, yes I would agree - it's quite complex.
Down the track, you might have to if you want to remove tilt and get the scope working at its best.
