Next Attempts at DSO's UpdatedI have been imaging using my SkyWatcher Startravel 102mm refractor on a Go-To Synscan alt-az mount and Canon 600D DSLR since just before Christmas 2015. Having since read, "Astrophotography on the Go" by Joseph Ashley I have been inspired to use longer exposures, typically 30 seconds at ISO 1600 and to take more images per object (up to 200 light frames) weather permitting. I use Deep Sky Stacker to collate frames and subsequently process the master image using StarTools. I hope this album of images shows improvement upon my earlier attempts.
Since April 2017 I have been using a SkyWatcher Star Adventurer (SA) mount on an old Celestron heavy duty tripod to image DSO's with my Canon DSLR. At Christmas 2017 I received a modified Canon 700D DSLR and an Astronomik clip-in Ha 12nm filter to complement my UHC filter. I am continually impressed by the accuracy of the little SA mount.
In January of 2018 I began using my old CG-5 Go-To mount to take images and later swapped the original Celestron polar scope for an modern SkyWatcher type which has made polar alignment faster and more accurate.
First Imaging Attempt UpdatedJust before Christmas 2015 I began taking photographs of DSO's using my SkyWatcher Startravel 102mm refractor, alt-az mount and Canon 600D DSLR.
To date all images except the Rosette Nebula have been taken using ten second exposure lengths and at ISO 1600.
Image processing uses Deep Sky Stacker and StarTools software.
Just before Christmas 2015 I started taking multiple short exposures of DSO's using my SkyWatcher Startravel 102 refractor, alt-az mount and unmodified Canon 600D DSLR camera. I use Deep Sky Stacker and StarTools software to process images.
