Description

I've had a few decent-ish nights recently, so, between 23 and 30 August, I was able to get 18 hours of narrowband on the Bubble nebula. (I'd got the idea for this target from Steve Richards.) I was fortunate enough to get 6 hours on each channel from my home observatory in Notts, UK. I wonder if it might be better to get 'a lot' more, especially of the SII and maybe the OIII.

Details:

Skywatcher Esprit 120

QSI 690 with Astrodon 3nm filters

Mesu 200

Ha: 18x1200"

OIII: 18x1200"

SII: 18x1200"

For a total of 18 hours
