M13
M13. 90x300s or 12.5 hours total exposure to get those fainter stars at the periphery. Taken in 2022, using a Celestron 9.25 SCT, QHY268C and an Optolong L-Pro filter. by Dean Ashton

M33 by Dean Ashton
M33 with Ha and RGB combined. Specifically 11hr20m (68x600s) of RGB and 4h20m (26x600s) of Ha combined. As you see, combining the Ha makes a big difference to the image. M33 is very active in star formation. THe Ha is also providing greater resolution of some of the larger nebula in M33 with structure in NGC604 becoming clear.
NGC 3031 – M81
Taken over three night during 2021 and 2022. Celestron 9.25 EHD @ f/7 74×600 sec subs using a QHY268C camera through an Optolong L-pro Filter. By Dean Aston
