This was one of the first DSO that I captured after I started astrophotography back in 2020 with a Canon 6Da and a Nikon 300mm lens. Since then, I have come back to the California Nebula a couple of times. Very impressive DSO! This is my latest approach from november 2023.
NGC 1499 is a huge hydrogen emission region that lies in the constellation of Perseus, some 1.000 lightyears away from my backyard. I appreciate that. Why? It is a perfect distance, because this way it fits the FL (350mm) of my TS Apo 71 Q in combination with the ASI 2600 MM Pro. :-)
I tried different ways to develop the footage, and this picture I like best. Nice color and nice details. I might gather more data, but first of all it should stop snowing. And then again - there are so many exiting targets - maybe I will wait until next year.
You can find more details on my Astrobin account. https://www.astrobin.com/61cevs/
Barnard 150, also known as LDN 1082 or Seahorse Nebula, is a dark molecular cloud of dust in Cepeus constellation. (Wikipedia) I wanted to capture this one including the nearby Fireworks Galaxy and the Open Cluster NGC 6939. Though they are all in the same frame, the distance to earth is way different. The Seahorse is only about 1200 lightyears away, while the Fireworks Galaxy measures about 21 MILLION lightyears. If you want to witness a supernova: NGC 6946 might be a good target, since ten supernovae have been registrated there during the last 100 years.
I might add more frames when weather clears up to improve star color and faint nebulosity. This is what I like about widefield framing: It may not show a lot of detail, but you get a great bunch of different objects in a nice starfield. And, by the way, the TS APO71Q is a really nice scope for astrophotography.350mm FL, easy to handle, great optics and usable with full frame DSLRs.
Below the main picture you find the annotated frame (left) and a diffferently developped version.
Here we have the Wolf-Rayet bubble in Cygnus. Very impressive ring-like emission nebula, „blown by the intense radiation and fast wind from the star“ (Wikipedia). This star is a Wolf-Rayet star, located in the constellation of Cygnus and called WR-134. „Due to a temperature over 63,000 K it is 400,000 times as luminous as the sun“ (Wikipedia). You can easily find it, it is the brightest white star more or less in the middle of the blue nebula. Total exposure time is around ten hours. I posted more details and a high res picture of this peculiar DSO on Astrobin.
down & left: This one has been developed to the Hubble palette, also in PixInsight, but with the ForaxxUtility, thanks to Paulyman Astro and TheColdestNights.com.
down & right: The OIII Channel only. Very impressive, I like!
I like the Tadpoles, and I like the music of Neil Young… Nearly missed his 78th birthday on November, 12th. Happy birthday! Keep on rocking like a hurricane, old man!
The two pictures below show different versions of the same footage.
The left one is much more colorful, due to the dynamic combination of Ha, SII and OIII using the ForaxxPaletteUtility in PixInsight, created by Paulyman Astro. Thanks for that - and thanks to The Coldest Nights, where this way of developing the Hubble Palette hast been explained first - as far as I know. https://thecoldestnights.com/2020/06/pixinsight-dynamic-narrowband-combinations-with-pixelmath/
The black & white one is the Ha-channel only. I love that one because the two "little" tadpoles can be seen so good...
The Flaming Star Nebula. Imaged this one nearly two years ago with my former ASI 294MM Pro. Re-edited it with PixInsight, which I did not use back then. IC 405 is a huge emission & reflection nebula in Auriga some 1.500 lightyears from earth. I really like the way it looks and the fantastic red colors from Ha and SII. Plan for this winter is taking a wide field image of the Flaming Star Nebula and the nearby Tadpoles. For details please check my Astrobin account. https://astrob.in/lnl1zu/0/
Nebulae, star cluster, galaxies: They all look impressive, and I really love to capture them with appropriate focal lengths to show details and color. Wide field astrophotography, to me, has it`s own attraction; and I like those wide field pictures a lot.
The picture above shows my first attempt in producing a wide filed mosaic. I chose the Sadr region (constellation swan) not only because it shows dust, color, stars and nebulae (e.g. the Crescent Nebula) but also because it was pretty high in the night sky and good to capture from my place. I wanted to keep things easy in the beginning. :-) Used my very first scope, the TSApo 71 Q & Nikon Z6a. It is a three-frame-pano, put together in PixInsight and finished in Photoshop. Total exposure time: 75 minutes. (3x25frames à 60s)
Loud and hot - and @night no clouds: I took some MilkyWayShots @ The Raut Oak Underground Music Fest. This one was shot with the Nikon Z6a and the 14-30mm f/4 S-line lens, taken @ 14mm. 12 x 10s. I love the red Hydrogen-areas, though it was kind of hard to separate the tree from the sky… Do you like it? And please do not say: NO!!! :-) Enjoy day & night…
This is one fascinating deep sky object! It was the first I was imaging when I got a mono camera and narrowband filters. Looks so cool in the Hubble palette…I re-visited IC 1396 now with my Esprit 100ED, and because of clouds only managed to get hold of Ha and OIII- photons…but… I am working on it. It is an area, where new stars are being born. My recent picture is in HOO, developped in PI, with the Oxygen blue rescued, thanks to Cuiv, the lazy Geek (thanks again!) - I like. Tonight clouds are kind of disappearing, so I might gather enough SII-photons for the Hubble palette. What I did. The result are a few different Hubble palette pictures. Which one do you like best? To me, te picture below on the right looks very nice...
