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.
The winter has not been great so far with heavy clouds and rain for most of January. February 10th 2021 was predicted to be clear and it was all night with temperatures dropping to -5C. My mount played up and the hub refused to work but I eventually managed to get 2hrs of decent images of the crab.

My Roll-off/roll-on observatory survived very well during the recent Storm Christoph.
The design is water tight thank goodness.

This is the result of 2hrs of images. It really needs several nights to improve the signal to noise and better conditions but I am pleased with it. Its surprising what can be done with a small scope (Bresser 150mm F5, Skywatcher coma corrector and 550D @ISO800 on HEQ5)
Trying to find the perfect spot driving around for 1/2 an hour only to find this great location just around the corner from my house. Thanks to the owner of the farm for permission to access his field.
