NGC-3628 Edge on Spiral Galaxy with Asteroid 3906 Chao
NGC-3628 Edge On Spiral Galaxy with 15.5 magnitude Asteroid 3906 Chao passing by on 02-20-2021 @ 08:46 U.T. to 10:15 U.T.
65 minutes total integration time.
NGC-3628, also known as the Hamburger Galaxy is an unbarred spiral galaxy about 35 million light-years away in the constellation Leo. Part of the Leo Triplet with M65 & M66.
It was discovered by William Herschel in 1784.
The Galaxy is way off in the background, but the Asteroid is much closer actually in our Solar system’s main Asteroid belt between Mars & Jupiter.
The seeing was terrible and very strong moonlight combined with the high haze barely showed anything in the 300 sec subs, but since I had just cleaned off 3 weeks of Snow & Ice from the top of my domes…I had to try to capture something. I was surprised that it even came out OK considering the terrible conditions. I managed to capture the interloper 3906 Chao (asteroid) as it left it’s little trail with a gap due to
some clouds that floated in during the shot. I placed the red arrow to show you the asteroid’s trail.

The First Quarter Moon 02-19-2021
The First Quarter Moon on 02-19-2021, Last Friday night it cleared long enough for me to get a shot off, It has been snowing and cloudy for the last 3 weeks…Saturday night cleared also, but seeing was terrible, atmospheric boiling with lots of haze,…so i am sending last Friday night’s First Quarter Moon since sky transparency was much better on Friday evening.
Captured with a C6 Newtonian Telescope & a QHY183M cooled Cmos Camera,
A single 60ms exposure, captured from my backyard in Dayton, Ohio.

M93 Open Star Cluster
Messier 93 or M93, also known as NGC 2447, is an open star cluster in the southern constellation Puppis.
It was discovered by Charles Messier then added to his catalogue of comet-like objects in 1781.
Caroline Herschel, the younger sister of William Herschel, independently discovered it in 1783,
thinking it had not yet been catalogued by Messier. M93 shines at Magnitude 6.2 is about 3,380 light years away,
and the cluster spans 20 light years across.
It is a brighter star cluster & easily visible in binoculars or a small telescope.
An Interesting find…
While doing some research on M93, my Jaw dropped when I read that
54 variable stars have been found in M93, including one slowly pulsating B-type star, one rotating ellipsoidal variable,
seven Delta Scuti variables, six Gamma Doradus variables, and one hybrid δ Sct/γ Dor pulsator.
Four spectroscopic binary systems within include a yellow straggler component.
Captured with an Explore Scientific 102mm Triplet APO Refractor Telescope, Bisque ME Robotic tracking Mount,
QHY183C Cooled Color Cmos Camera, and a 30 minute exposure on 01-10-2021 from my observatories at JBSPO in Yellow Springs, Ohio.

Jones-Emberson 1, or PK164+31.1, The Headphone Nebula
The Headphones was a tough faint one, a dying star blowing off its outer atmosphere!!!!
Jones-Emberson 1, or PK164+31.1,
also known as the Headphone Nebula, is a 14th magnitude planetary nebula in the constellation Lynx
at a distance of 1600 light years.
It is a larger planetary nebula with a very low surface brightness, making it tougher to see or capture.
In my long exposure you can easily see that the 16.8-magnitude central star is a very blue white dwarf, also visible are many other faint tiny background galaxies, including two faint ones behind the central opening in the planetary nebula.
This was a tough faint one for the little 4inch and 6 inch scopes!!!!…but after 8 hours and 15 minutes of exposure integration over 4 nights, I got a decent shot of it.
I captured 5 hours 15 minutes(63 x 300sec subs) of QHY183C Cooled (OSC) RGB Camera Data with
the 102mm Refractor Scope and combined it with 3 hours(36 x 300sec subs) of H-Alpha data with the 6 inch Newt. Scope, QHY183Mono Camera as the Luminance Channel. Stacked in DSS and aligned the data from separate scopes/nights in Maxim DL,
and then final in Pixinsight & Adobe CS 2021.
Some Historical stuff…
Discovered in 1939 by Rebecca Jones and Richard M. Emberson, its “PK” designation comes from the names of Czechoslovakian astronomers Luboš Perek and Luboš Kohoutek, who in 1967 created an extensive catalog of all of the planetary nebulae known in the Milky Way as of 1964. The numbers indicate the position of the object on the sky. “PK 164+31.1” basically represents the planetary nebula that when using the galactic coordinate system has a galactic longitude of 164 degrees, a galactic latitude of +31 degrees, and is the first such object in the Perek-Kohoutek catalog to occupy that particular one square degree area of sky.

The Waning Crescent Moon with Earthshine on 01-10-2021
The Waning Crescent Moon with Earthshine on 01-10-2021 at 07:02 am EST. After pulling an all night deep space imaging run, i was about to close my dome up, when I seen this beautiful crescent with Earthshine rising above the tree line that morning, with thin clouds passing over it, so I had to take a quick shot before closing up that morning. Explore Scientific 102mm F7 (750mm) Triplet APO refractor & QHY183C Cooled color Cmos Camera, a single 2 second exposure to show the Earthshine.
