Oct 2nd, 2020 – Mars and Moon Conjunction

Moonrise!

A beautiful evening for the Moon and Mars conjunction on October 2, 2020.  Condition were so good that I was able to capture the moon rising behind a tree.   Usually the muck is so thick at that altitude that I would not be able to get a good image, but this night it was extremely transparent.

The moonrise shot was a single frame.  I had to do a composite for the still image of the Moon and Mars together.   10 frames were stacked in AutoStakkert of just the moon and 2 Mars frames were combined for the disk of Mars.

The MP4 video file is the first time I have tried including one in a astrophoto post.  It is small enough in size to download in a reasonable amount of time.  Video editing software I used was rudimentary and I really couldn’t get the background color corrected very well.   I’ll have to find something that can do that job for future projects like this.

The Butterfly Nebula

For a night with a full moon, this came out pretty good.  Good transparency helped.  Minimal processing with only color balance and saturation/hue adjustment tricks were used.

M16 – The Eagle Nebula

I shot this while waiting for the Moon and Mars to get higher in the sky on Friday, Oct 2nd, 2020.   After shooting some moonrise shots, I turned the scope to this and got 40 minutes of sub-images before it went behind a tree.

It was also the first time I imaged using a generator for power and a battery backup unit to keep the scope running if I ran out of gas and had to refill the tank.  I got a great deal on the generator that I could not pass up.   It will work better in the field with my current imaging setup than the battery system I had before.

Trifid Nebula, M20 in 16 Minutes

Trifid Nebula, M20 on Aug 21, 2020. 65×15 sec, Gain 30, Offset 218, Optolong L-eNhance filter, QHY183c at -10C, Televue TV-85 at F/5.6.

Here’s a very short run I did on the Trifid Nebula.  An extra short quickie with only minimal processing.  I was interrupted by a couple of young gents who saw me imaging in the front parking lot and wanted to see what I was up to.   They also wanted to see Jupiter, so I obliged.  By the time I got back to the Trifid, it was already about to go behind a tree.  Oh, well…

I am hoping to get this object with about an hour of exposure at least, if not more.  To that end, I added what I had taken before with my SN8 and Canon XT camera to see how it might look.  The additional data was 54 minutes of 3 min ISO 800 subs.  It is about a half-n-half blend:

Combined data from SN8 scope and Televue TV-85 scopes, about 70 minutes total.

M8, The Lagoon Nebula on Aug 21, 2020

M8, the Lagoon Nebula on Aug 21, 2020. 240×15 sec, Gain 30, Offset 218 QHY183c at -10C, Optolong L-eNhance filter, Televue TV-85 at F/5.6.

I had been wanting to get some data on this one for quite some time.  Finally, a clear night with no big commitments the next work day came along on Thursday evening, Aug 20, 2020 and I got my chance.

I setup my rig in the front parking lot of the place where I stay at instead of the usual back alleyway.  It was the only place to get a clear view without trees and street light glare interfering.

I used the Optolong L-eNhance filter, which works really well for this object.   I did an hour’s worth of exposure, which was enough to tamp down the noise enough for a decent final image.  It could use more and I might add to it later if I get the chance.
