Equipment Details:

Used a Meade Coranado PST Hydrogen Alpha scope and a ZWO ASI224MC planetary camera, manually guided the mount using alt and az knobs manually... no electronic tracking or guiding.

Post-processing Details:

Used Autostakkert to process the ser file captured by Sharp Cap Pro, Best 10% of 2000 frames. Processed to get an inverted image and other details using IMPPG, then used Gimp to adjust the color balance of the image. This process in a work in progress as I am still in the development stages of learning Sharp cap.

Image Details:

Sunspot 3092 and 3093 and a rather large filament are visible in this capture.
