NGC 4244 Edge-On Galaxy in Canes Venatici

NGC 4244 on Jan 17, 2021. 61 x 180 sec, QHY183c at -20C, Gain 11 (Unity,) Offset 100, Baader UHC-S filter, Televue TV-85 at F/5.6.

3hrs of exposure for this nice edge-on galaxy.  It got cloudy towards the end of the run and there was a serious guiding error on the full 61×180 sec stack.  But, I managed to salvage the stack by copying the background and galaxy and pasting that in as a lightened blend on top of a 47×180 sec saved stack for the stars that did not have a guiding error.   Lucky I saved it before it got ruined.

Here is a closer crop with a saturation boost:

Black Eye Galaxy M64

Another Black Eye galaxy shot to add to my collection.  Not quite the guiding I was getting earlier in the evening, but it is not too bad, either.  Minimal processing done to this one.

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.

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:
