The Cave Nebula HaRGB on dual Esprits

[gorann 3,039]

Friday and Saturday night were supposed to be clear, and the obsy roof was off and I was out getting everything ready - but in vain. Then on Sunday night, which had no great forecast (and I had to get up early on Monday), it was suddenly totally clear. The guiding suggested a modest seeing (RMS around 1"/pix) and  SQM was 21.0, which is ok but far from the best I get here. I used my dual rig on the the Mesu 200 with ASI1600 for Ha on the Esprit 100 (3.5 nm Baader Ha, 46 x 10 min, gain 139, offset 50, -20°C) and ASI071 for RGB on the Esprit 150 (85 x 5 min, gain 200, offset 30, -15°C). Ha mainly added to the red channel using lighten in PS and a bit Ha added as lum. Stacked in PI and the rest in PS. Totally 14.75 hours.

Thanks a lot Steve! Fortunately most of it was done while I was asleep, except the processing.....

What? You can't do the processing in your sleep?

Thanks! Sleep stacking is a good idea, especially with the high number of subs produced by CMOS cameras.

I had a go at adding more dust to the image using the interesting PS method Olly @ollypenrice recently posted. I think I like it.

I am indeed, in collaboration with @Tomatobro a dual Esprit 150 rig will be put together in the not too distant future.
