Whirlpool Galaxy (M51)
In 2017 I went through a major upgrade of my imaging equipment and moved from a SW NEQ6/SW ED 80 to a SW Esprit 150/10micron GM1000HPS combination. In the course of testing my new mount in unguided mode I took some M51 Lum test shots at 600 and 1800s with the Esprit 150. Rather than waste this data I decided to see if I could use it to try to improve an Ha + LRGB image that I had acquired in 2016 with my NEQ6/ED 80 combination.
Since I've never tried to blend data from two difference telescopes, I decided to take the lower resolution post processed Ha + LRGB image and to treat it as "RGB" data (this image can be seen in my gallery Deep Sky II M51 reprocessed). I then took the higher resolution Lum data that I had acquired with the Esprit 150 and used this as a Luminosity layer within PS (I aligned the Lum and "RGB" data via Registar). After a little processing in Pixinsight and PS I got the above result.
