Arp 275/NGC 2881 is a pair of colliding galaxies in Hydra nearly a quarter billion light-years from earth. Arp had no category for colliding galaxies. Though...

Sometimes an image turns out very differently than you expect. This certainly is one of those. I never suspected the galaxy was ringed by galactic cirrus. ...

I originally did this image in 2008. Recently I was asked if I had a version showing more glare from the bright star just south of the galaxies. I...

Back on May 14, 2017, amateur astronomer and super nova hunter Patrick Wiggins discovered a brightening SN in Arp 29/NGC 6946. It eventually became known as...

Arp 290 is classed by Arp as Group Character: Wind Effects. This is the first of this odd class I've imaged though two more are awaiting processing. It...

Arp 292, IC 575: What is it like to be run over by a hoard of geostationary satellites? This one is in the geostationary satellite belt as seen from my...

Arp 3, MCG-01-57-016, is a low surface brightness spiral, which is also where Arp put it in his catalog. It's located in Aquarius a bit southeast of the "Water...

Arp 300 is in his class "Group galaxies: Double galaxies. They are UGC 5028 and UGC 5029, right to left. But UGC 5028 is itself a double galaxy MRK 111...

Arp 321, Hickson 40, is a tight group of 5 galaxies, 3 of which are certainly interacting. Most catalogs list them as a through e but can't agree as to...

Arp 53/NGC 3290 is located in Hydra about 490 million light-years distant according to its red shift. Arp put it in his category for spirals with high...

Arp 63/NGC 2924 is a multiple galaxy in northwestern Leo about 320 million light-years from us. Arp puts it in his category for spiral galaxies with small,...

I've never been happy with my 2008 image of Arp 78. I tried this August on a night of good seeing to get better luminance data. Unfortunately the weather...

This is a reprocess of an image taken back in 2009. My processing toolkit was limited as was my ability to use what tools I had. So it was time to redo it...

Arp 92 falls under Arp's class: Spiral galaxies with companions on arms: elliptical galaxy companions. If by "companion" Arp includes unrelated line of...

Arp 98 is a pair of interacting galaxies. Arp classed them under "Spiral galaxy with companion on arms: Elliptical galaxy companions." The spiral is LEDA...

Through a Celestron SP-C102 (4" f/9.8 achromat) with a Nikon D40x. Celestron IR/UV blocking filter. Bud -- The night is just the shadow of the Earth.

Normally I don't take main belt asteroids, only near earth ones as they pass by but I made an exception here. I doubt many have heard of Nagin Cox, but you...

Asteroid (3122) Florence came closer to the earth on September 1, 2017 than any asteroid its size or larger has since we've been keeping records of such...
