Messier 3 in LRGB

This was the first night I have used NiNA, with fully automated focusing and meridian flip. The scope also auto-parked and the camera shut down at the end of the session. This software is so good, I was more than happy to make a contribution to encourage its further development.

The image is one of the most detailed I have achieved, mostly down to the sub-arcsecond auto-guiding but the new coma corrector added some needed sharpening of the stars which is quite important when pixel peeping the core of a globular cluster.

Imaging details:
3.5hrs (30m L, 60 each RGB) total.
ASI1600mm Pro, ZWO filter set, Lacerta CC, Bresser 150/750 on a CEM70G.

Messier 97 in SHO + L first narrow band attempt and using the "Hubble Palette"

Messier 97: The Owl Nebula


Imaged on the first of two clear nights in April and is my first complete SHO image using the ASI1600MM Pro. Imaged with Bresser 150mm@f4.8 using a Skywatcher 0.9 CC. Mounted on my CEM70G.

Conditions were very good and the CEM70G tracked wonderfully well with sub 0.5" in RA and 0.61" overall. Which is exactly where you need it for this scope.

Sadly the Bresser lost its collimation by the time the L-subs were taken, this resulted in the stars not being round.

Final image:
Gain139,offest50 @-15C. S 10x300s, H 16x300s, O 16x300s, L 12x120s approx.

Processed in Pixinsight with a final tweak in Paintshop Pro.
