Crab from raw Hb S2 10f4 00 85 BiColor Image.jpg

Crab  in Bi colour Hb Sii  

(10"f4 with Atik 414ex)

( H beta  ?? x 1min and Sii 85x 1min)

I like the colour combo here.    Looks like one of those electric space storms that the USS Enterprise tends to fall into.

Near to morning this one, tracking was better than my last attempt, but I cant find a record of how many HB subs I took....  doh!!

Thanks nice Sean. I’ve never imaged in H-beta before nor seen it. 

Due to a couple of 'accidental' second hand purchases, I have a mixture of filters in my EFW2, which is slightly irksome. 

LRGB Hb Sii are Baader, Ha and O3 are Astronomik !!  ... and yes they are are not parfocal. Hence my enthusiasm for Bi-colour shots.
