B33 the Horsehead Nebula

I took this using the remote scope at the SLOOH obervatory in the Canary Islands, 17 minute exposure. 11L 10B 8ea R & G

Nice Jeff!

I’m seeing several vertical lines. Any idea what I’m looking at?
Thanks,
James

That's fantastic!

Dead columns often caused by dead pixels, I normally am able to remove them through processing. The company that owns the scope and camera should be doing new darks to get rid of them but since the two observatories are very remote they are only able to do them when they go there (to my understanding). One of the downsides to belonging to a club or community scope you are a little at their schedule. I should have taken longer in the processing phase.
Living in a red/white zone (bortle 7.5-8) I mostly do solar from my backyard using a Lunt LS80 or my Daystar Quark with one of my refractors. Slooh or other subscription equipment (such as ROBOSCOPES.com) lets me image from a dark sky site.
Some people say it is cheating because I didn't buy the scope and camera, rather rented it (in my case a yearly subscription) so it is not my picture, but if I rent a Canon 1DX and take images with it, do they not count and are not my own images?

Interesting. It actually looked almost like scratches on film shots that were caused by something on the felt of the canister or rollers in camera. I knew it wasn’t that, but but sure caught me off guard.

Cheating!?? If someone thinks that is cheating, then I’m inclined to say anything and everything is cheating, unless the image was captured with the person physically present and touching/controlling the mount and scope, etc during whole stack. (Is that a sentence!?)

Keep them coming. Hopefully they will get the fixes for it soon.
Best

Narrowband. I live in Henderson, NV, just a stone's throw from the Las Vegas strip under Bortle 8-9ish skies and I can do 5 to 8 minute subs in Ha, OIII, and SII from my backyard.
It's really quite enjoyable. And using a program like SharpCapPro you can LiveStack these exposures for really amazing detail if you don't want to bother with the processing.
This is 2 hours of 5 minute subs in Ha only from my backyard taken straight from SCP.
