My latest process using data from Grand Mesa Observatory’s system 1 the Takahashi FSQ 130 (available on our subscriptions) using a QHY367C full frame One Shot Color CMOS camera with Chroma Narrowband Filters. I recently processed this same area with narrowband filters in a hubble palette rendering www.flickr.com/photos/terryhancock/48762002422/in/datepos... but this time around I have used the RGB together with H-alpha data
Captured over 6 nights in June and July 2019 for a total acquisition time of 18.75 hours.
