Oct 2nd, 2020 – Mars and Moon Conjunction

The Moon and Mars on Oct 2, 2020. TV-85 at F/5.6, QHY183c at -15C, L-eNhance Filter.

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.

Imaging Session Aug 8th, 2020

Witch’s Broom Nebula. 1.75 hours in 30 sec sub-images, gain 42, offset 150, QHY183c at -15C, UHC-S filter, Televue TV-85 at F/5.6.
The Moon on Aug 8, 2020. 7 frames stacked with SharpCap 3.2 LiveStack, UHC-S filter, QHY183c at -15C, Televue TV-85 at F/5.6.
Pacman Nebula – 188×15 sec, Gain 30, Offset 150, QHY183c at -10C, UHC-S filter, Televue TV-85 at F/5.6.

The night of August 7th/8th, 2020 was relatively clear, but hot and slightly muggy.  Average transparency at first and below average towards the end of the night.  I wanted to get out to my dark sky site, but at the last minute decided to stay in the big city, being that the conditions were not ideal.

I observed quite a few things and did quickies on them and some of the images are not really worth being posted.  Here is one below of the Ring Nebula, which was.  I was actually after the little galaxy next to the ring,  IC 1296, which my Canon cameras never showed despite shooting the ring with them from much darker locations.   It is nearly 15th magnitude and even dimmer in blue light, where it predominantly radiates

Ring Nebula and IC 1296. 372×15 sec, QHY183c, Gain 30, Offset 50, -10C cooling, UHC-S filter, Televue TV85 at F/5.6.

Below is a rendition from previous sessions data and this nights efforts.

Ring Nebula and IC 1296. 34×30, 4×15 sec, Gain 42, Offset 100, 372×15 sec, Gain 30, offset 50, QHY183c -10C to -15C,, UHC-S filter, Televue TV85 at F/5.6.

Finally, with the Witch’s Broom Nebula data from this night and 2 other nights, I combined the data to make this updated rendition of the W. Veil/Witch’s Broom Nebula.   Check it out:
