M8 Lagoon Nebula

[Decimus (Richard)]

As Sept 18 was the first clear Saturday night we had down in Tassie in ages, I used my ZWO ASI071 for only the second time since I purchased it in 2019 )or was it 2018?/) Anyway cooled it to -19 and took just 20 lights at 10 seconds and 10 darks. There are two versions - the blue version and a redder version. William Optics GT 102, Vixen SXD 2 mount and Sky X Pro for image capture. Quick processing in PS 2020.

Will post both, just for the sake of comparison. Also imaged Eta Carinae and M16 (which I will post separately.

Cheers,
Richard

Same tech details as for the redder version below.

Looking nice Richard
Thought you'd have gone and shot it with the big telescope

Good to see a big deep field which we don’t often get around the lagoon. I do prefer the purple version.

Thanks, Colin. I am such a newbie at all of this. The APM might get an airing at our astrocamp in November (at Font Hill, not far from Oatlands in Tassie. Excellent dark skies, when they happen).

By the way, I discovered only this week that I had not turned on the dew heater in the ASI071MC - confusing instructions from ZWO, so I wrote to them (they implied 0=On and 1=OFF when switching on and off through the software (SKY X in my case). The reverse is true, of course! No wonder I had the dew problems months ago when I tried to image Eta Carinae.

Ah well, live and learn...
Cheers,
Richard

Thanks, Ray.

On a cropped sensor CMOS like the one in the ASI071MC, the slightly larger Lagoon image works well. If I had used my Nikon D850 on the scope it would have been too small.
