As I Tue, 09 Feb 2010 00:51:09 GMT Neil Fleming http://tech.groups.yahoo.com/group/astro_narrowband/message/6420 http://tech.groups.yahoo.com/group/astro_narrowband/message/6420 Since I shoot with a refractor for the most part, my data is somewhat undersampled.  In this situation, I do NOT like to bin at all.  Like in LRGB Mon, 08 Feb 2010 18:47:59 GMT Cesar Cantu Quiroga http://tech.groups.yahoo.com/group/astro_narrowband/message/6419 http://tech.groups.yahoo.com/group/astro_narrowband/message/6419 Hello Jen, J-P: Thank you very much to see and to comment.

Binnin is a very usefull feature with NB imaging! You can have much higher S/N with a cost of some resolution.

It would be helpful to post the details of your set-up at the same time.

They are only 2,30 hours, with subs of 600 seconds. 4 in Ha, 6 in O3 and 7 in S2.

This is a very good start, you really should take more lights for this. Total exposure time is way too short.
