M8 is very low in the southern sky from my SF Bay Area location.
Worse, it's buried in heavy light pollution. I've been putting the
4.5nm Custom Scientifc filter through its paces and have found it
to be very effective in mitigating effects of light pollution.
Details:
AP 130 @ F/4.5,SBIG ST-10XE ccd,SBIG STV guider
120 minutes using 10 minute subs, 4.5nm HA filter.
Maxim for acquisition, sigma combining, digital development, bloom removal.
Post processing (levels, curves and touchup) in Photoshop
Background smoothing using Pixinsight
This image is 50% of full size. The original image from which
