I initially set out to capture IC 1805 and IC 1795 as a traditionally framed "Heart," but when reviewing the data I was struck by the strength of the Oiii and the notion of Melotte 15 as a cosmic bolt of lightning -- launching a fish swimming in this ocean of doubly ionized oxygen into space.

I kept this image in mind as I processed this data I captured over 10 nights this January, and I feel the starless version does a better job bringing this story to life. Perhaps planetary nebula WeBo 1 (to the left and slightly down from the center of the frame) looks a bit out of place in the starless version, but I think it belongs in the scene!

The image comprises 27.75 hours of integration (roughly equal parts of H-alpha and Sii, with a bit more of Oiii), and was taken from my backyard in Santa Monica, CA under Bortle 7 skies.

Processing was done entirely in PixInsight in the Hubble palette, and the gear used was as follows:

Camera: ZWO ASI6200MM-pro
Scope: William Optics Fluorostar 132mm Refractor
Mount: Astro-Physics Mach2GTO
Filters: Chroma 3nm Ha/Sii/Oiii 50mm
Guide Camera: ZWO ASI174MM-mini
Accessories: ZWO OAG-L, Pegasus Powerbox Advance

C/2022 E3 (ZTF) Comet visiting Auriga

It hid under the clouds for a long time, and when it cleared up, she hid in the moonlight, finally managed to catch this one hour of the dark, cloudless sky - and is - in the beautiful company of hydrogen beauties from Auriga.

The frame was taken with Samyang 135m/2 lens and modded Nikon D610.

Andromeda Galaxy M31 and its small galaxy neighbor M110 is a favorite and often photographed target in the night sky. In the constellation of Andromeda, named for the princess who was the wife of Perseus in Greek mythology, it’s certainly the perceptually largest galaxy visible from our vantage point on Earth. M31 is approx. 152,000 light years across and 2.4 million lightyears away from Earth. It’s just visible with the naked eye as a fuzzy disc with a diverted gaze and clear night in dark skies. I had two nights of clear skies recently while awaiting comet c/2022 e3 (ZTF) to rise high enough to shoot. It’s pretty late in the season to shoot Andromeda in my neck of the woods but I had time to kill and I hadn’t photographed it for a couple of years. This photo represents a total of about 7.5 hrs of integration. I took these photos on Jan. 29th and 30th. I used a Williams Optics Redcat51 paired with a ZWO 294MM. It’s an LRGB photo processed in Pixinsight.

The Two Comets

On a cold night, documenting the conjunction between the weak comet C/2022 E3 (ZTF) and Mars. Thanks to a perspective effect with the dark dust of our galaxy, Mars also seems to have a dust tail like a comet. In the frame also the Pleiades. A beautiful memory of the passage of this curious comet, renamed the Neanderthal comet.

"THE GREEN "NEANDERTHAL" COMET"
- Deep Sky 750mm LRGB
- Constellation Auriga



I was lucky when this current celestial highlight migrated south and met Mars, it was a nice cold clear night from February 08th to 09th, 2023. Encouraged by the many beautiful shots I have seen of it meanwhile, I have it made it my task to photograph him for more than 2 hours, with a mono and LRGB filter set - knowing full well that he is a speed junkie, and rushes through the solar system like Flash ^^
After a month-long break, I didn't even know if the equipment was still working properly - there were of course problems with NINA, who didn't want to change the filters in a rotating manner - so I came to the compromise solution that I recorded the individual color channels in one set one after the other - not rotating as recommended. But, as it turns out, I seem to have put enough effort into the editing, and you hardly notice it ^^

The magnificent Rho Ophiuchi Cloud is large nebula located in the southwestern corner of the constellation Ophiuchus which surrounds the triple star Rho Ophiuchi. The intriguing and yet spectacular colors emanating from this dense region let us understand quite easily how intense processes are going on there.

I hope you will like it.

Clear skies,
Aygen

Monoceros Neighbourhood by Andre Vilhena, no Flickr

Monoceros constellation is famous for its hydrogen rich emission nebulae, such as the Rosette and Cone Nebula, but it also features some beautiful dark and emission nebulae. The field of view in this photo shows an area where all these types of nebulae can be seen, from the hydrogen emission (here in red), emission nebulae like IC 2168, NGC 2245 and NGC 2246 (the blue areas) and also some scattered dark nebulae.

Despite being in my list for some time, this photo was a last minute decision, while I was waiting for comet C_2022 E3 (ZTF). The same happened to Ha frames, taken with almost Full Moon - I wasn’t expecting much of it but it ended up being enough to enrich the photo.

Comet C/2022 E3 ZTF rising behind Yosemite Falls

Click to view full size image

I carried my astronomy/photography gear down a treacherous icy/snowy path to the banks of the Merced river in the Yosemite Valley with an incidental and thankfully brief bear meet and greet on the walk down to take images for this picture of Comet C/2022 E3 ZTF as it rose behind the magnificent Yosemite Falls. Visually, I could barely make out the comet; it was a nondistinct fuzzy smudge. The camera with a single exposure also struggled. (https://flic.kr/p/2ogD9aZ)
For this picture, I used a stack of 15 two-minute exposures (tracked on the stars) to create a comet image. With stacking, I was able to bring out the faint details in the comet tail. The comet image was then blended into an exposure of the foreground. Yosemite Falls was lit by the 35% waxing crescent moon and looked freaking amazing in the moonlight. I did not change the size or scale of the comet, and if our eyes could see exponentially better than they can in the dark, this is technically what I would have "seen" instead of that fuzzy green smudge
I hope you enjoy it!

SH2 308 "Dolphin Head Nebula" by Harley Grady, on Flickr

SH2-308, commonly known as the "Dolphin Head Nebula" is a HII region located in the constellation Canis Major. It is approximately 4300light years away. he massive star that created the bubble, a Wolf-Rayet star, is the bright one near the center of the nebula. Wolf-Rayet stars have over 20 times the mass of the Sun and are thought to be in a brief, pre-supernova phase of massive star evolution. Fast winds from this Wolf-Rayet star create the bubble-shaped nebula as they sweep up slower moving material from an earlier phase of evolution.


This image was captured with a ASI 2600MC Pro OSC camera and a TS-Optics 90mm CF APO f.6 Refractor (543mm focal length). I used a optolong L-eXtreme filter to capture the narrowband data.
