Sometimes I just want immediate pics

Sometimes I like to do live imaging just to get immediate results.

This is from a 2 hr session last night, just after the moon set. Done on my ASI224MC (which I has just got the amp-glow circuitry upgrade at ZWO).

These all done on f5.9 80mm refractor with focal reduction (~ x0.6 with a meade f3.3). Used a UV/IR filter. All images at high gain (250), 15 sec subs. Total exposure of 1min (the two clusters), or 4-5min. No guiding.

1 = 47 Tuc, Cat's Paw Neb, IC4628, Dumbbel Neb
2 = Helix Neb, Lagoon, M7, NGC346
3 = M24, NGC4945, NGC5128, Trifid Neb
4 = Omega Centauri, Sculptor Galx, Skull Neb, Swan Neb

Images captured and stacked in sharpcap then automatically opened and contrast/colour adjusted in astrotoaster. I ran this on a PC stick attached to the scope which was remotely controlled via wifi from a laptop indoors.

I've crammed the pics together, but haven't done any post-processing.

Edit-have made images larger at the expense of extra compression
