Comet C/2025 K1 ATLAS in Ophiuchus - Aug. 16, 2025
Comet C/2025 K1 Atlas cruzing through northern Ophiuchus.
This image is 21 minutes of exposure time using my C-8 at f/7.
Atlas is a small comet moving very fast to the south and west
making short exposures necessary to avoid streaking.
To make this image, I stacked 24 comet images without stars and then
took the last 5 images and removed the comet to get stars only.
The two image sets were combined and cropped to 14' x 21'.
North is up.

Comet 3I/ATLAS in Ophiuchus - July 16, 2025
The monochrome image above is interstellar comet 3I/ATLAS.
It is the small labeled dot at the center.
The stars are streaked because 16 subframe photos of 1 minute each were aligned on the comet's changing position.
The comet is still outside the orbit of Mars heading for its closest approach to the sun this winter.
3I/ATLAS was discovered around July 1 and I wanted to try and image it as soon as possible.
At the time I photographed it, the COBS (Comet Observation database) was showing the comet's magnitude around 17.3 or so
- very faint for an extended object.
I tried 30 seconds, 60 seconds, and finally 120 seconds exposures.
I ended up using the 60s subs but the comet was not visible on the screen at the time of capture.
Only after calibration and using plate solving, did I get a hint of a smudge just above the background noise.
Nothing I could do to the photo in Pixinsight gave a result that was publishable,
so I turned to ASTAP.
After using ephemeris alignment and stacking was I able to produce the image above.
At the time this image was captured, the comet was still in a fairly star dense part of the Milky Way.
The image has been cropped down to about 4 by 6 arc-minutes from the original of 41 x 31 arc-minutes.

TNO Haumea in Bootes - June 17 and 20, 2025
This animated GIF shows the very faint TNO (Trans Neptunian Object) Haumea
moving among the stars of southern Bootes
about 7 degrees SE of Arcturus on June 17, 2025 and June 20, 2025.
A white tic mark has been added to aid in finding the object
which at the time was only magnitude 17.3!
Haumea was moving 2 arc seconds per hour giving a total of 2.4 arc minutes of movement
over the three day time span shown.
For reference, the field of view of the photo is 19.5 arc minutes wide,
or 2/3 the diameter of the full moon.
Haumea was 49.4 AUs from Earth, taking light 6 hours and 51 minutes to reach from it to the Earth.
Capturing these images was very challenging.
Haumea was at the limit of my 4" scope and camera combination from the suburbs in summertime.
Haumea is the third largest TNO behind Pluto and Eris.
Haumea also has two small moons orbiting it.

M95 M96 M105 in Leo - Mar. 22, 2025
Bright Leo galaxies M95 M96 M105 plus others.
This photo was for the RAC second quarter image challenge to photograph a field of galaxies
with at least 3 galaxies in the same FOV.
Most of the data shot in this photo (70 minutes) was on Mar. 22, 2020.
22.5 minutes was shot back on May 9, 2020.

Jones-Emberson 1 in Lynx - Feb. 2, 2019 and Apr. 24, 2025
This is the faint planetary nebula Jones-Emberson 1.
It is also known as the headphones nebula.
The image is shown with south at the top to show the face wearing headphones look.
The image is unguided since I managed to break the guide camera adaptor as the guide scope
slid off the main scope at the start of the session.
This image was reprocessed in April 2025 using the 2019 data and produced a much better result.

Comet 29P/Schwassmann-Wachmann - Feb. 28, 2025
Comet 29P/Schwassmann-Wachmann 1 in Leo, not far from Regulus.
So far this year, not to much has been happening for relatively bright comets.
However, this one is special to me.
It was my 90th comet of my astronomy career either seen by eye or photographed.
This guy was faint at around mag. 11.5.
It was almost invisible on the individual sub-frames.

The Andromeda Galaxy - Dec. 30, 2024
The Andromeda Galaxy M31 with the RedCat 61 f/4.9 300mm.
This is my first try on this object with the RedCat and I like the wide FOV.
It took a while to post this one due to dust motes on the camera's optical
window after a desiccant change. The uneven background was difficult to deal with.

A dusty M45 in Taurus - Dec. 3, 2024
The Pleiades (M45) with lots of associated blue-white and brown nebulosity.
I'm still having fun seeing what the RedCat 61 will do with wide field objects.
I put M45 to the upper left side of the frame to give extra room for the dark nebulosity
to the right and below.
The stars and nebula were processed independently to stretch the nebula without blowing
out the stars.
There were plenty of neighborhood lights on brightening the sky.
M45 was approaching the meridian at the end of the imaging run.

North American and Pelican Nebulae in Cygnus - Oct. 24, 2024
The North American and Pelican Nebulae in northern Cygnus.
We have had a very long run of clear skies here in North Carolina,
so even though C/2023 A3 has been getting all the attention lately, I decided it was time
to try a little regular deep sky photography with the RedCat 61.
As is usually the case for me, I shot a set of exposures broadband for natural star color then
a set of exposures narrow band for the nebulae.
The last time I tried for this pair was with a DSLR and 135mm lens
at the Staunton River Star Party almost exactly 10 years ago.

Comet C/2023 A3 Tsuchinshan-ATLAS - Oct. 20, 2024
Comet C/2023 A3 was finally visible without moonlight for the first time
since it moved into the western sky.
I finally got to use the RedCat 61 on a tracking mount so I could stack
some individual frames.
At this focal length, the whole tail will not fit onto the frame which is
3.6 degrees top to bottom.
The comet is quite a bit fainter than a week ago but the anti-tail is still showing nicely.

Comet C/2023 A3 Tsuchinshan-ATLAS - Oct. 14, 2024
Comet C/2023 A3 looked much better tonight from my light polluted area.
I was at the Crabtree Lake Dam which was busy with other comet chasers and the usual hikers
and bikers.
A cold front came though today clearing out the high clouds and haze.
Even with better conditions, I could not see A3 naked eye,
but was able to find it in binoculars so I could point my camera.
A careful look at the photo will show a hint of the anti-tail that has formed as well
as globular cluster M5 embedded in the tail near the top.

Aurora over Cary - Oct. 10, 2024
Tonight we had red/pink aurora over Cary NC.
This photo came from round two around 10:45pm. The first round happened around 7:30pm.
I took this standing in the street in front of my house pointing the camera NNE.
Visually the aurora was much less impressive as the photo shows.
It was mostly a pink glow to the north-east.
