Messier 63 - LRGB

I still have a few things to crack like the differential flexure and misting up of the camera that trashed most of the subs I took in a 3hr session. As a result, I don't have much colour in the galaxy itself.

All things considered this is not a bad image. Its probably the last galaxy I'll shoot for this half of the year. We won't be having astronomical darkness for a couple of months now.

Messier 63: The Sunflower galaxy
Messier 63: The sunflower galaxy. Just over 1 hour of LRGB subs. Imaged with ASI1600mm Pro with the Lacerta coma corrector. 250mm Orion Optics newt on the CEM70G. Captured with NINA and Processed in Pixinsight.

Messier 51 and first light for my Orion Optics 250mm rebuild.

This LRGB image is the result of 3 hrs of imaging with many lost subs due to cloud and some RA imbalance issues. Probably only 1.5hrs with most of those softened by clouds. This results in a noisy and more washed out image than I would have liked. Still, compared to my first attempts, 14 yrs ago, it's not bad.

Imaged with the ASI1600MM-Pro, ZWO filters, Lacerta Komakorr Coma Corrector. modified Orion Optics 250mm Next on the CEM70G.

This was first-light for my refurbished scope the Orion Optics 250mm newt. I had the mirrors re-silvered last summer, I flocked the tube and replaced the focuser for a Skywatcher low-profile Crayford. I've just finished making a brace for the rings - to stop ring wobble - which it does very well.

The Lacerta Komakorr Coma Corrector is a big improvement over Skywatcher 0.9 CC. Sharpness has improved across the image, its very noticeable. Continue reading "Messier 51 and first light for my Orion Optics 250mm rebuild."
