Stellarvue AP50 ED APO or AT65EDQ?
Posted 08 October 2012 - 05:36 PM
If doing widefield imaging with a CCD camera with small chip size like Atik 428 EX, would you prefer the Stellarvue AP50 ED APO or AT65EDQ and why?
Both acopes are exactly the same price, so price is not an issue.
Thanks for your help

EDIT: unless they've changed it, the stock focuser on the AT65EDQ is great. With a retrofit stepper you're set.

That's a very good reason.
One question: what is a retrofit stepper?

I have a microtouch focuser with a feathertouch for my C6 SCT. I just didn't know the term.
The small APO would be a secondary scope to the C6 SCT. I've considered hyperstar but I know I'll do narrow band imaging in the futureand don't want to deal with changing filters manually.
One of the main options would be the 428 mono and would like to have a scope that allows the bigger objects to fit in the small sensor.

Any focal reducer for the SV50?
I don't think so because it already has 330 mm of FL. I'm not sure if it needs a flattener.

I am in the same boat of deciding between these two.
Instead of using a CCD, I am going to start with DSLR and this is going to be my first AP setup (with iEQ30).
I read somewhere (cannot find it anymore) about the focuser issue on AT65EDQ. Do you guys have moreinformation about this ? Is the 10mm aperture difference going to make any difference ? Thanks.
