Further on M27

Maybe this is not a very good object to practise Ha imaging? I’m not sure what the main consistentency is of this object…. the outer halo does not show very well, and also all blue parts are not visible. I guess this is a work in progress.

Anyhow this is a test object just to get my SGP and automated focusser / filter wheel working. That doesn’t go vbery smooth. I lost a few hours last evening under a clear sky, tampering with the PegasusAstro focuscube, trying to get it working with SGP’s autofocus. In short: it’s not working yet! The picture below is M27 with 178 minutes of H-Alfa.
