The Sunflower Galaxy – M63
A quickie Sunflower Galaxy. Needs more exposure, obviously. I killed some time waiting for M64 to get into position shooting this.
M64 Black Eye Galaxy
This object was the main goal of the night. Not quite the 3 hrs I wanted to give it, but almost. I took a nap while this was brewing, and ended it since the mount needed a meridian flip to keep going. Instead of doing that, I decided to get M13 instead.
Here’s a detail crop view with a little more color saturation to go along with the above:
M13 Globular Cluster – QHY183c
Last object of my imaging session for the night of Feb 1st/2nd, 2020 was the globular cluster, M13. Twilight was just starting when I stopped at 100 sub-images. Not too bad for a quickie.
Comet C/2017 T2 PANSTARRS
crop.
Here is an image of a comet that is big and bright enough to make some interesting images, especially when it passes near objects like the Double Cluster. I missed the closest approach of these two due to weather and other factors, but at least I got the parting shot of them together.
M78 Reflection Nebula in Orion
This one was difficult to bring out the nebula since the UHC-S filter blocks some of the blue that this object predominantly shines in. But, it captures enough of the OIII, Hydrogen Alpha and Beta light to produce an image even from the heavily light-polluted location that I’ve been imaging from.
The Rosette Nebula
I was surprised how well this came out with only about an hour of data. I was after galaxies this night and I only took this to kill time. Even the 33 minutes worth I posted initially looked half-decent. I will have to devote a session to this one and possibly use the L-eNhance filter instead of the UHC-S.
Edge-On Galaxy NGC 4565
3 hours of exposure for this object. I used SharpCap 3.2 LiveStacking and a Baader UHC-S filter to cut through the light pollution in a Bortle 8 Red Zone metro area.
TheWhirlpool Galaxy – M51
M51 on Jan 25, 2020. 280 x 30 sec, Gain 42, Offset 15, -20C, UHC-S filter, QHY183c, TV-85 at F/5.6.
Leo Trio with Baader UHC-S
Finally, the weather cleared after several weeks of clouds. This is typical for December down here in Cajun Country. With the clear conditions, I got a chance to try out a new UHC-S filter I purchased from Baader Planetarium. It replaces the cheap generic UHC filter I got from Amazon. Still shooting from the big city these days in Bortle 8 Red zone is a good test of these filters to see how much LP gets in and how well galaxies and nebulae show up.
I found out the L-eNhance filter doesn’t do much for galaxies unless they have lots of H-alpha regions. An hour worth of subs I took at the beginning of the month of the Leo Trio barely had anything worth keeping, so I only blended about 25% of it in to this image. The 450×30 sec Live Stack with dithering turned on I acquired in SharpCap 3.2 and the UHC-S filter was good enough to stand on its own.
Minimal post processing was done for this one, which is always nice after staying up all night imaging. lol 🙂
Before I shot the Leo Trio, I did a “blue test” on the Pleiades. I have 16 minutes worth of data and it shows how well this filter does with broad band and non-h-alpha objects. Check it out:
