The California Nebula from a Bortle Red Zone

The California Nebula – 1×300 sec @ ISO 200, Canon XS (modified,) 72mm Lumicon Deep Sky filter, IDAS-LPS drop-in filter, Canon 200mm F/2.8.

Here is a one exposure image taken in the middle of a Bortle Red Zone with 2 light pollution filters in place to help with all the LP.   I managed to get quite a bit of nebulosity with 5 minute sub-images at F/2.8 and ISO 200 on my older, modified Canon XS camera.

What helped was the sky conditions, which were very transparent and clear.   I am glad I did not waste one of the few great nights of the year.

The above image is just a tease, btw.   I have a number of these subs just waiting to get calibrated, stacked and processed.   I will probably just tack the finished product onto this thread when I am done.

Edit:  Done!

There you go.   Tacked on as promised.  lol    I accumulated almost 2 hours worth of data and considering the location, it did not come out too bad.

Comet Imaging – C/2017 O1 ( ASASSN )

Comet Asassn on Oct 18, 2017. 60×180 sec @ ISO 200, IDAS-LPS, Lumicon Deep Sky, Canon XS (modified,) Canon 200mm F/2.8 lens.

I tried for Comet Asassn and even with 60 subs, I did not get much.   The Canon 200mm F/2.8 lens was just too small of an image scale to do it justice.  Bortle Red Zone conditions did not help.  Plus, the parking lot lights from the nearby theater were still on for most of the imaging session.   When they go off at 2:30 am, I can see about a mag to a mag and a half dimmer stars in the sky.   I can do 5 minutes exposure instead of just 3 with them off and it makes a difference in the final outcome.
