I’ve been working on the Pacman nebula over the past few days but I thought I’d make a start on the California the other night. I’m Just amazed the difference this mono camera is having for my narrowband images.

Look forward to adding some more subs and potentially OII and SII

16 x 5min HA




M106 and companions

M106 from the 22nd and 23rd March. I havent been able to get any HA images of 106 yet but im pleased so far with the LRGB data. I did have an issue with what appears to be CA (chromatic aberration) although this is likely my fault as im new to combining RGB images. Ian King is currently looking at the scope for evaluation. 100×1.5min luminance 20×1.5min RGB



First HALRGB M101

Decided to add in some HA i had collected on M101 bringing out some lovely red star forming regions. Its a bit of a learning curve with this like everything in astronomy as i had to mask the master HA considerably before adding it to the red channel. By masking so heavily i inevitably discarded most of the HA data i had collected which is a disappointment but thats something ill know for future galaxy images.
