Early this month my long awaited ASI2600MM arrived, and the sky duly cleared for that evening and the next (And not since) so it was a mad frenzy to get it set up and out for first light.
The target chosen was SH2-34, which is near M8 and is relatively strong in HA, has some Oiii and I don't know about Sii as my Sii filter only arrived last week (Fedex managed to take three weeks to deliver it within Australia, two of which were a little holiday in Ballarat, where it remained until I started making phone calls) I had made a start on this image with some HA data shot with the previous camera (The ASI2600MC) but decided to abandon that. All data in this image is from the 2600MM. This is 32 X 120 second R-G-B subs, 19 X Oiii 1200 second subs and 18 X 1200 second HA, all at zero gain and 50 offset with the camera cooled to -10. Integration of the various filters in Astro Pixel Processor and RGB combination and addition of the HA-Oiii in Photoshop, calibration by master flats from 25 flats each from the various filters and a master bias created from 100 bias frames. I am pretty happy with this for a first light and for my first proper mono image.

I have posted this before, but this Astrobin link is an animated gif comparison of the HA data shot with the mono camera versus the data shot with the OSC and debayered with the HA algorithm in Astro pixel processor. Moreal of the story is if you can afford it, don't calculate something you can measure, or in AP terms, don't interpolate what you can natively capture.
