Description

The Cave Nebula (Sh2-155) in narrowband.

Due to continuing fog here, I decided to bin the images 2x2 and go for shorter subs. It took 12 nights over late august and early september to get enough to make this image.

Image is 40 Ha subs, 21 Oiii subs and 19 Sii subs; Ha subs are 5 minutes, binned 2x2 ... Oiii and Sii are 10 minute subs binned 2x2.

I drizzled the subs and used the Ha as a Lum for this version (Rev A)

Rev A = My preferred green palette

Rev B = My blue-green palette

Rev C = closer to a traditional SHO Hubble palette (but let's face it, I am a little goofi)
