This is an imaging list for myself to follow. The reason it does not include all objects may be due to my surrounding garden views or that some distant objects are just too small for my telescopes.

M52

I have imaged M27 before using RGB filters, but this time I decided to use narrowband filters. I used Hydrogen Alpha (Ha) and Oxygen III (OIII).

This image was taken on a Meade 127mm triplet telescope with an Atik 314L+ CCD camera. The exposures were 3 minutes long each, about 10 of Ha and 10 of OIII were stacked and aligned.

I then mapped Ha to Red, and the OIII to both Green and Blue.
