How good is my guiding and imaging scope?

[coenie777]

Could someone with technical know how on guiding please comment on what I hope could be a shot that could answer the following:

- Is my guiding/mount good enough for decent long exposure images of Deepsky objects?

- Is my scope good, very good or average in terms of how it presented the image.

The first shot is a crop of the extreme lower right hand side of the 1200" image I took under heavy light pollution. I tried to minimize it a bit with PS levels but the histogram has three humps for each channel and I did not want to tweak too much. I reduced ISO to 100 to combat the LP.

I also include the uncropped full frame shot without any darks or flats added.

I would appreciate any comments.

Guiding was via Orion Mini 50mm with SSAG under PHD2 and ST4 mode at 1x for RA and DEC. Focal length was only 420mm so that must help a huge lot.
