Observing Log for Mike Durkin


12/23/2019 about 6:30PM-11:00PM
Locust Valley, NY
Transparency: 7/10, Seeing 3/5
Temperature: 30-40 degrees
Equipment: Canon Rebel T3i and 200mm lens

I originally tried to use the AstroTrac, but it looks like the Duracell battery is finally at it's end. Even though it should be fully charged, the meter says 0% capacity. I need to figure out a way to dispose of and get a replacement.
So instead I switched to the Star Adventurer. I took some images of the Heart Nebula, comet C/2017 T2 (PANSTARRS) and the area around the star Atik to see if I can pick up some nebulocity.
I have to remember though that when using the Star Adventurer like this, the camera is 90 degrees from what I would normally expect.
Also should note that even though I could not visially see clouds, some of the images definitely showed a think layer of clouds.

Heart Nebula
Location: Locust Valley, NY
Camera: Hutech modified Canon T3i
Lens: EF200mm f/2.8L II USM at f/3.2
ISO: 800
Exposure: about 418x15 seconds (104.5 minutes)
Mount: Sky-Watcher Star Adventurer
Calibrated with dark frames and flat frames
Processed in MaximDL and Photoshop with Astronomy Tools

There were also some gradients in this image that I had trouble with.

Comet C/2017 T2(PANSTARRS)
Location: Locust Valley, NY
Camera: Hutech modified Canon T3i

ISO: 1600
Exposure: 113x13 seconds (24.48 minutes)

There seemed to be some extra color gradients that were a bit of an issue.

Just a quick visual measurement of α Ori.


12/21/2019 7:30-9:00PM
Locust Valley, NY
Transparency: 6-9/10, Seeing ?/5
Temperature: 25-35 degrees
Equipment: Stellarvue 70mm

After readong about comet C/2017 T2 (PANSTARRS), I decided to tryto find it. I was able to find the right field of view according to Sky Safari, but I was not able to see any coma. Along the way I did pass over star cluster NGC 1528, but could only see a few stars in the cluster, mostly with averted vision.
After that it got too cloudy for me to try to observe any variable stars.
