Astrotrac or CG-5
Posted 29 January 2013 - 05:23 PM
I have a quick question .I am just starting out in AP and I have a chance to get one of these mounts...
Which one do think I should I get???
I can't decide... A CG-5 is a great stable platform but not very travel friendly...
An Astrotrac is just way cool... but twice as expensive..

Other travel systems include the Vixen Polarie (the lightest) and the new iOptron SmartEq Pro (GEM).

As other posters have said, though, its all a mater of what you want to do with it. I find my CG-5 is good for planetary and lunar photography, and limited deep-sky. If I don't have any wind at all and a really good alignment, I can usually get a 30 second exposure without much problem. Anything more than that and my stars tend to be more egg-shaped (or worse!). I've had no luck with guiding on this mount (though I know some have). All-in-all, I can't recommend a CG-5 for deep-sky AP. (I'm sure I'll get some replies to the contrary).
I do think my CG-5 is great for visual work with up to an 8" scope. My GoTo's are spot-on once properly aligned (and balanced) and it tracks nicely for visual work. Its also not too big to easily transport in a car.
If you're really interested in deep sky work, I'd recommend upping your budget and getting into the CGEM/Atlas-EQ range. That's where I'm going soon.
Anyway, just my $0.02. Your mileage may vary.

Go to a few star parties and see what people are really using before making any decisions. You will find both CG5 and Astrotraks out there----but neither will be the mount of choice for those who are really into the imaging thing.

If you end up going to a GEM, the CG5 is easy to outgrow. The AstroTrac can also be a second travel mount or dedicated wide-field mount. So even if you eventually go to a large setup, you may find the AstroTrac handy. Remember, you can't have enough gear...
