Still waiting on my Omen laptop so I can learn stacking and processing ( suppose to have it next week )
Snapped some single frame images of the Lagoon and Swan nebulas between breaks in the clouds down at my holiday pad on the south coast
Bintel GSO 6” f6 reflector on a HEQ5 Pro Mount with a stock Canon 600D
Unguided
1 minute 20 sec exposures at ISO 3200
Tried ISO1600 to reduce some noise but not enough image detail to show nebulosity ( if I was guiding I could have possibly run 3 or 5 minute exposures to expose more detail )
Polar aligned sub arc minute using Synscan PA routine ( took me 8 iterations to get there 1hour later )
Lost a fair bit of detail and sharpness through emailing files and reducing small enough to post
Those single frames are looking really good. If you're able to maintain round stars for 1min 20sec without guiding that's excellent, definitely must be on the money with your polar alignment.
I also own a stock 600D and have found it to be a good camera over the years, particularly in winter. In summer the noise can be a bit of an issue, but dithering really helps with that.
I used to perform iterative alignments, however, now I just use the SharpCap polar align feature with my finderscope and find it generally takes only 10mins or so. It used to take me 1hr as well when I was doing the iterative method.
I look forward to seeing more of your stacked photos in the near future.
Picking up my Orion 50mm guidescope and ZWO 120MM camera tomorrow morning at Bintel
Laptop should be landing next week so I’m going to busy down loading and learning all the Astro software programs (Ascom, EQMOD, Stellarium, Stellarium scope, Backyard EOS, PHD2, DSS, Autostakkert, Startools and various drivers etc... )
