Hi All,

Processed the data from last night.

M20 in Ha, SII, Ha, OIII (90, 30, 90, 30 minutes), SII and OIII binned 2x2.

There's a rainbow effect off to the RHS of the nebula which was caused by my main mirror fogging from dew. It was exceptionally cold here last night, I didn't notice that I had condensation on the inside of the RCX until this morning when I went to put all the covers back on. Both the back of the corrector and the mirror had condensation, looks like I'll have to run the fans all night.

Cheers
Stuart
