Henry Curry built the Grade II-listed Pump Room for the 7th Duke of Devonshire in 1894 due to overcrowding at the previous well in the Natural Baths. It was last used to “take the waters” in the 1970s.
The Pump Room now houses the Buxton visitor centre.
M13 Great Globular Cluster in Hercules
Had a few cloudless hours to grab an easy target. It is the first DSO I have imaged since November. Either my sky conditions have really deteriorated since November or there were some high thin clouds. Either way it was good to give the gear a run.
I tried something different and shot 200 Luminance filter subframes only 5 seconds each. I combined this with some RGB I shot in 2013 from my QHY23M and AT65. The large number of subframes really seemed to produce a much cleaner image. In a few months when it is clear again I will give 100+ subs a try again

This incredibly detailed image of the interacting triplet M81, M82, and NGC 3077 was created from more than 216 hours of exposure across three continents — Europe, USA, and Oceania. We combined 4019 subframes and 12993 minutes of exposure to reveal faint details previously masked by lower amounts of data. The high exposure time also allowed us to sharpen fine features, giving the image more contrast and revealing more fine structures.
On the top of the image lies NGC 3077, a small starburst dwarf galaxy with a starforming core. Below lies M81, a grand design spiral about 12 million light years away. To the right is M82, a starburst galaxy with a huge superwind triggered by interaction with M81 and NGC 3077. All around the image is the galactic cirrus, dust lit by the glow of the milky way. I highly recommend looking at the image with HI emission overlaid, which displays what of the background is neutral gas from the interactions and what is dust from the milky way.

NGC 6910 is an open star cluster set amidst clouds of gas and dust near the bright star Sadr in the constellation Cygnus.
Subframes for this image were accumulated over 4 different nights, some under dark skies near Goldendale, WA and others from within Seattle city limits. RGB data for the stars was combined with narrowband data for the gas and dust, with Ha assigned to R. In an effort to maintain a "natural" appearance, only modest amounts of SII and OIII data were added to the G and B channels, respectively.

A quote by Jung about exploring the Psyche.. I think it applied here too, at least it was in my head getting this view. Another trip to the river , its a long drive to this place and trying to time my original idea hasn't worked out in about just over a month.
Eight feet up a vertical rock wall to stand on a two foot square ledge with another sixty foot drop to the rocks and river below with a pack and heavy tripod. Thankfully the rocks have ledges that stick out and I could grab onto the trestle uprights to hold on once I got up there so this was from inside the trestle bridge, interestingly it was the last shot I took before I went to climb back down and leave.
Will I go back for the original shot... I don't know for now, maybe this is why I kept going back and just didn't know it. We'll see.

Thanks for checking out my work...Appreciate all of you.

This is a significant image in that it is the longest exposure I've ever taken. 583 60-second subframes, which is about 9 hours and 43 minutes. That doesn't include the few frames that were flawed by satellites trails or tracking issues. This was taken over two nights.
Here is comet in color , I found set of three RGB subframes 60 sec each and stack and processing in PI .Taken on Jan 20 , 2020 with SBIG ST-8300 CCD camera through TS 130 mm APO refractor working @ F/7 and Deep Sky Astronomik filters.
This stack of 18 images contains nearly the entirety of the constellations Andromeda, Cassiopeia, and Perseus. Numerous outstanding objects are within its bounds. From left to right (roughly east to west), they include:
The Pleiades (M45, lower left corner)
The California Nebula (NGC 1499, above the Pleiades)
The Double Cluster in Perseus (NGC 869 and NGC 884, near top center)
The Heart and Soul Nebulae (IC 1805 and IC 1848, above the Double Cluster)
M34 (open star cluster, bottom center)
The Triangulum Galaxy (M33, along the bottom border, right of M34)
The Andromeda Galaxy (M31 and satellite galaxy M110, bright elongated object in lower right area of image)
Subframes were taken with an astrophotography modified Nikon D5100 at ISO 4000 and focal length of 18mm. Stacking and processing in PixInsight, with a few final touches in Photoshop.
The solution for the image from astrometry.net places the center at
RA 2h 3m
DEC +50° 20'
Andromeda-Galaxy (M31) over pine trees near my observatory. The circle next to my name represents the apparent diameter of full moon relative to the same conditions. I used the 8 last subframes (of a large series) to an integration (8 x 80 sec, ISO 4000) and one single frame (1 x 80 sec, ISO 400) for a atmospheric composite. Sony A7s (CentralDS), Canon 200/F1.8 @1.8, L-pro filter, EQ8 mount, Tenerife, Canary Islands, 1180 m altitude.
Located in the constellation Triangulum. Takne through NP127is 5 inch refractor at f/4.2. Collected with a Canon 7D MKII. approximately 4 hours total exposure of 7 minute ISO 1600 subframes. Taken at Grandview Campground.
This image shows two groups of galaxies. You might recognize Stephan's Quintet, the galaxies near the lower left corner, as the conversing angels in the movie “It’s a Wonderful Life”. 😀 The Deer Lick Group of galaxies, with NGC 7331 as its largest member, is near the upper right corner.

IC 443 also known as the Jellyfish Nebula is a supernova remnant (SNR) in the constellation of Gemini. Its distance is approximately 5,000 light years from Earth and a diameter of 70 light years. This image has been processed in the style of the Hubble pallete using two narrow band 3nm filters of Ha and Oiii. This helps to separate the two gasses from each other.

I imaged the Flaming Star Nebula using two different smartscopes with dramatically different results. There were also differences in post-processing that influence the differences. The two smartscopes' cost was nearly identical. No one scope is better than the other, but each has a distinct look. See below for comparison.
IC 405 also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31,
Seestar S50. This is a composite of 567 ten-second exposures (subframes). Taken January 26, 2025.
this is actually a reprocessing of the image I took earlier in the year, now that I have a slightly better understanding of how to process astro images, another challenge is that instead of a stack of one hour of data this is simply a single 2 minute subframe stretched, very happy with how it came out
Everybody's favorite. The tug of war between two galaxies.

Is it feasible to take an image of the Virgo Cluster with a DSLR and a relatively tiny telescope? With access to some dark skies, I decided to find out. This is a stack of 48 images taken with an Askar FMA135 (30 mm aperture) on an astrophotography modified Nikon D5100. Subframes were calibrated with darks and flats in PixInsight, and the initial stacking and processing was done there. Exposures were at ISO 6400 and generally around 60 s. The alignment I got with the move shoot move Nomad would have allowed for longer exposures. This introduced some color noise that took some effort in Photoshop to remove.
I have close up images of many of these galaxies taken with my own Celestron Edge HD 925 and with the C14 at Cerritos College. Take a look at M58, M59 and M60, M84 and M86, M87 and Markarian's Chain, M88 and M91, M89 and M90, M98 and M99, and M100. At the beginning of 2024, there was a supernova visible in NGC 4216. I was able to follow its progress with a few more photos from February 3rd and February 12th of that year. I've also shot NGC 4567 and 4568 when there was a supernova in one of those galaxies.
But yeah -- here's all of those galaxies -- plus more -- all in one shot.
For this rendition of the 2-panel mosiac, I ran all of the subframes through the same PixInsight WBPP run so that they would all be at the same local normalization, I applied ChannelCombination to the RGB masters for each panel separately before merging the panels, and I produced separate star and nebula images before applying nonlinear stretches. The stars image was stretched delicately while the nebula image was stretched very agressively. I like the stars that resulted from this treatment.
