Description

This is Small Rosette Nebula (Sharpless 170). It is a rarely imaged object, but it looks pretty nice.

It is a fairly small object, so needs 2000mm FL to get a close up of it.

I tried capturing it in SHO palette but was not able to get much of O channel, so I decided to mix H as red and added SII for green and blue while trying to keep colors reasonably natural. On top of it, I added colors into stars from RGB channel.
