Description

Captured this with the Rasa11 and 6200MM. 2h O3 and 2h Ha, both 60s exposures.

interestingly, some of the pictures out there show a lot more O3 in the Lobster Claws, but looking at the actual data it's both heavy in Ha and O3. So this is more true to form.

Had troubles with my O3 Flat, messed something up there so ended up with bad vignette in O3. Cropped a bit.

Stars over the Rasa F/2.2 field were decent, the same Crop also got rid of the worst stars in top-right.

I like the widefield of this. Lots of interesting things to look at. At 60MP the details are everywhere.

Might want to get SII but not soon
