Selling the Sky-watcher r.a. motor drive for eq2/cg3 mount.
I was using it on my Celestron Astromaster 130eq. I was able to do some astrophotography with it, 15-20 seconds exposure time.
Price £27 plus postage
Payment method: PayPal, family and friends method or commercial and buyer will pay fee 3% extra
Hi, there will be plenty written on this but I’d be grateful if anyone could point me in the direction of a well written beginners guide. I am awaiting delivery of a 10 inch Dobs (250p classic) and although will be primarily for visual use I’m interested to see what would be possible astrophotography wise (planetary) using my Celestron Skyris 132C cam. I assume something along the lines of the drift method - I’m not expecting miracles given the set up here but any advice or tips on this would be appreciated to help get started.
Recently I acquired the eq3 mount and now I'm looking for Skywatcher Dual Axis or enhanced dual axis Motor Drive for this Mount .
I'm considering the 250PDS. The main use is visual, and the second is EAA (I currently use a zwo183mm).
What I'm hesitant about is the primary focus. since It's mostly for visual, I'm wondering on how much back focus it has compared to the standard Skywatcher 10" dobsonians? with the standard dobsonias with the same optics and focuser you already need an extension tube for most eyepieces...
Also, there's probably a "bigger" obstruction (bigger shadow on primary)?
