Clamshell Nebula Sh2-119

[carastro]

Haven't done any imaging for a couple of months as not set up for small galaxies and can't do broadband from home (Bortle 8).

Also, I seem to have done all the popular nebulae that I can do from home, so am now doing the less well known, but fainter targets. This is the Clamshell Nebula (to the left of the North America nebula).

I did take some Oiii and Sii but could not find any signal at all in Oiii and Sii was only faint, so didn't show up when combining with Ha, so I processed as HaRGB.

Samyang lens and Atik460EX on HEQ5
Ha 13 x 900 (3h 15m
RGB 11 x 125secs binned x 2 @ 23mins each
Total imaging time 3hours 24mins

Thanks Guys, I decided to have a go at SHO using Olly's method of "Bringing out the faint stuff" (using Photoshop's equalise function) and have managed to get enough to produce an image. Unfortunately though I hadn't got much data with Sii and Oiii as I had given up and decided to go for HaRGB instead.

Ha 13 x 900
Oiii 4 x 450binned
Sii 2 x 450 binned
I know I should have got more Oiii and Sii, but was so disappointed with so little data showing I gave up and went for HaRGB instead.
But today i decided to "have a go" and see what I could do with SHO and the equalize function.

   Wonderful images Carole!

   Thanks for sharing & congrats on the APOD.

A very fine SHO rendition Carole. The equalize function appears to have found a lot of information from such a small data source.

Congratulations on the APOD.

Hello Carole. I love both images, but your extra effort really paid off on the second image. Beautiful color and details in the nebulosity. Thanks for sharing these with us on here Carole, and congratulations on winning the TSS APOD Award today.

Looks like you picked a tough target Carole especially from your location. Nice work bringing out some of the fainter nebulosity. Congratulations on the TSS APOD.

Both exceptionally beautiful images. Congrats on the well deserved APOD!

[carastro]

Thanks for all your nice comments and Gordon for the TSS IOTD.
I feel embarrassed now as I had forgotten I had posted the image in TSS and hadn't looked in again until today because I have another image to post and found all these lovely messages.

Great images Carole. I have not seen 'Equalize' used in such a manner. Nice one. Congrats on the APOD.

[carastro]

If any-one is interested in the Equalize function in Photoshop that I used for bringing out the faint stuff, I made a video tutorial on it.

That is a great video Carole. The process is very well explained. A professional demonstration

It is lovely to hear your voice too :smile:
