Two colorful clusters

Gregg Ruppel
 

Hi all:

Here are two very colorful (as in gold and blue) open clusters:

NGC 1662 in Orion

RGB, 1.75 hours total exposure from Dark Sky New Mexico

NGC1746 in Taurus
http://www.greggsastronomy.com/IMAGES/ngc1746-RGB.jpg

RGB, 3 hours total exposue from DSNM

Comet A1 Leonard 12/5

Gregg Ruppel
 

Hi all:

Leonard continues to brighten and grow his tail; I'll need a bigger FOV soon:

LRGB, 30 minutes total exposure from Dark Sky New Mexico.

NGC 2371 + 2 (PK 189+19 1, PN G189.1+19.8 and others) is a planetary nebula located approximately 5068 light-years away in Gemini. At magnitude 13, it shows up as two objects visually – the reason for the two NGC numbers. This one is about three degrees from Castor.

 

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 10:8:8x300s – 50:40:40 minutes each – binned 2x2

 

370 minutes total exposure – 6 hours 10 minutes

 

Imaged November 13th, 14th, 15th, 29th and 30th, 2021 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

UGC 2275

Gregg Ruppel
 

Hi all:

UGC 2275 is a delicate face on spiral, about 6 arcminutes in diameter, magnitude 13.4.  I couldn't find much about it online.  IC 1085 is the small face on spiral in the lower right quadrant:

Hi Dean:
I used my ASA 10N astrograph and STL11000M CCD to acquire the data. I imaged the background a couple of days before the comet arrived, 5 minute exposures in LRGB.  I used a combination of 1 minute exposures and 30 second exposures for the comet, again LRGB total about 50 minutes.  All images were calibrated and stacked in MaximDL; the comet images were stacked on the comet nucleus, median combined which eliminated most of the star trails.  The comet image was then layered over the starry background in Photoshop using the Lighten blending mode and masks.

Clear skies,

Gregg

It's between 6 and 7 right now, easy in binos.  It should continue to brighten between now and Dec. 12 so it may reach 4th magnitude.  It will be low in the morning and evening sky around the 12th.  Here's the magnitude graph from aerith.net

Clear skies,

Hi all:

Comet c2021 A1 Leonard is bearing down on the globular cluster M3 in Canes Venatici.  It will be slightly closer tomorrow morning (12/3) after passing almost directly over the globular.

Great catch Brian.  I was able to capture A1 and M3 in the same frame (full frame CCD).  Posted.

I got this shot three hours ago from building 7.  Five 5-min shots were taken, then the roof automatically closed due to 80+% humidity.  It’s rare to have such high humidity out there in the desert.  But I was able to get a good shot, stacking those five frames.

IC 348 (also known as IC 1985) is a rarely imaged open star cluster surrounded by a reflection nebula. The reason this object is not imaged is due to the very bright star glare washing most of the detail away. I spent five hours slowly expanding this image to fight of the glare and reveal the wonderful image you see here. The light from the roughly 400 stars in the cluster is scattered by  clouds of dust in the star-forming region, producing the reflection  nebula.
