NGC 300 - longest integration yet attempted

Around 3 1/2 hours' worth in total, taken from two nights (Mon & Wed just past).

Mon was 14 x 4-min exposures at ISO 400; Wed was 49 x 3-min exposures at ISO 800.

On Monday my alignment was pretty terrible so the guiding was struggling. On both nights the collimation was off.

Flats, darks and bias used, however there were some corners cut; I used older master darks with the right ISO but shorter exposure times (my intervalometer died last night). The flats may *possibly* be from another, different brand 8" f/5 Newt, not 100% sure.

I'm reasonably happy with it; it's pretty noisy, but I'm not expecting much from my little D3300 considering what I paid for it.

My main complaint is that I don't really know what I'm doing with DSS. Once the TIF is created I'm reasonable at editing it, but I'm sure there are better ways to stack than just leaving everything at default settings. This is the first time I've tried combining different ISOs & exposures.

I also don't know how to tweak it in Photoshop. I know my way around Photoshop for portraits but this is a VERY different game and I don't really know what tricks to use.

Any tips very welcome! Thanks for viewing.
