Until recently I could not even fit IC 405 on my CCD (or CMOS) chip, but with the TS 60mm ED plus 0.79 reducer I can even get IC 410 (and parts of IC 417) in...

NGC 6852 is a blue planetary nebula in east-central Aquila. I found distance estimates ranging from 5,100 light-years to 13,800 light-years. The most recent...

Edit: Unfortunately I can't edit the title on the main page. It should read NGC 7731, NGC 7732 and IC 1504. Why I imaged this field is a mystery. It's...

"The Fath is a small cluster of galaxies, near the center of the larger cluster Abell 262. Located in Andromeda, it is at a distance of about 210 million...

IC 226 and IC 227 are the largest members of the MCXC J0228.1+2811 galaxy cluster. The cluster is located in the southeast corner of Triangulum and is just...

Berkeley 103 is an obscure, little studied, open cluster in Cassiopeia. WEBDA and the one paper I found on it agree that it is about 6850 light-years distant...

I'm now up to the top end of the M list cleaning out the hard drive. I was shocked to find this unprocessed set of M92 frames from last summer. How I...

I wanted to get a fast scope with a focal length around 1 meter, so I bought a Skywatcher Maksutov-Newton with 190/1000 last November. There has not been a...

NGC 7407 is a somewhat unsymmetrical spiral galaxy with a huge faint looping arm to the south unlike any to the north. It is part of a group of galaxies about...

PGC 9247 is a SAB(rs)bc spiral galaxy about 210 million light-years distant in the southeast corner of Andromeda. While its core region is relatively bright...

I've been monitoring the nebula around PV Cephi (Gyulbudaghian's Nebula) since 2011. Each year changes are seen but nothing nearly as dramatic as when my...

Berkeley 54 is a very old star cluster, as open star clusters go, with an age of about 4 billion years. Most clusters of this age have long since been torn...

NGC 7193 is considered by some to be an asterism, others such as SIMBAD say it is an open cluster. But the only paper on it that I found says it is an OCR. ...

Arp 309 is made up of two interacting galaxies, NGC 942 (lower) and NGC 943 (upper). The pair is located in Cetus about 200 million light-years distant. ...

NGC 7311 and 7312 are two spiral galaxies seen against the distant galaxy cluster, Abell 2454. The field is "above" the neck of Pegasus the horse that flies...

ABELL 2593-S is the southern part of the ABELL 2593 cluster. The northern part is out of my image, to the north, obviously. It is located in Pegasus just...

the Custom Scientific 3nm FWHM filters were confirmed tonight to split the very close emission lines of the doublet at 658.4 nm and the Halpha line at 656.4...

I wanted to image Planetary Nebula M 2-52 with my 10" Meade ACF, but noticed that I would get M 2-51 with half the focal length. It is only 13 arcseconds large...

Attachments failed to attach even though they were seen in the preview. I'm trying again. Berkeley 82 is a small open cluster in northeastern Aquila. It...
