Processing an ultra deep 393h collaboration of M81/M82

Image: Gigapan link here: https://www.gigapan.com/gigapans/232382 I highly recommend zooming in on all of the smaller background galaxies! Image with HII This image has all HII data from the VLA added in blue-green, which highlights the extent of gravitational interactions. Gigapan link here: https://www.gigapan.com/gigapans/232383 You can view all the details and interesting features of the image here: https://www.astrobin.com/tb0sou/ Processing The processing steps here are a result of an iterative processes where I determined the best methods for this dataset. I processed the entire dataset a total of 12 […]

NGC 6888: The Crescent Nebula

This is another image from telescope live: the Crescent Nebula. It was a tough dataset to stack, as there were a bunch of dead pixel lines from the CCD. However, once the dataset was stacked, it was quite fun to process. The Oiii data was extremally strong, and it was really interesting to see the extent of the wispiness around the nebula. I’ve been experimenting with a new “natural” pallete made from SHO emissions, and I think it turned out pretty accurate! NGC 6888, also known as […]

Peering deep into the the core of M42

This is yet another image from telescope live. Although the total exposure time was a little over 45 minutes, the fact that Orion is so bright meant that the snr was still quite high. I’ve been iterating through versions of this image to figure out the best method of HDRing the core, and I feel like I’ve been settling on a pretty solid method using MMT. The detail in the core that I managed to pull out is really interesting to look at, so I highly recommend […]

Stars and Globules in the Running Chicken Nebula

Here’s an SHO image from telescope live. This dataset had a pretty interesting quirk, which was that some of the given astronometric solutions from telescope live were formatted incorrectly, which broke WBPP and forced me to do some shady coding. Anyway, I’ve been working on a new method of SHO processing using MMT and GHS to even the midtones of each channel, which give the final image a lot more color. It also helps that this region has such a big diversity of gas emission. To some, […]

The Glowing Hand of God (CG-4)

This is yet another telescope live image. The H-Alpha data really made this image come to life – it was actually a bit disappointing seeing how little dim dust the RGB image contained when comparing to other images. Regardless, seeing the depths of the hydrogen gas was really stunning. I’ve also been working on a new processing technique where I separate broadband and narrowband gas, which allows to to better control both levels. I think it works quite well! Can a gas cloud eat a galaxy? It’s […]

Dust and starbirth in Perseus: NGC 1333 and IC 348

This is another image from telescope live – a widefield of the Perseus region, including IC 328 and NGC 1333. It was a pretty tough dataset to work with, as there were a ton of gradients that were hard to get rid of. I decided to try SPCC in pixinsight on this dataset, and it seems to work pretty well. I couldn’t notice a really significant different between PCC and SPCC, but SPCC seems to work faster for me. IC 348 is a star-forming region in the […]

Reflection and emission in SH2-311: The skull and crossbones nebula

Yet another image from telescope live. This was a super fun dataset to work with – even though the total integration time was only 6h 40min, the data was very clean and easy to play with. I decided to experiment with a way to separate broadband reflection and H-alpha emission using continuum subtraction only from LRGB data. Even though this method isn’t very “scientific,” it does an extremely good job of letting me enhance different parts of the nebulae. I haven’t seen many LRGB images of this […]

The Eagle and Omega Nebula in the Hubble Palette

This is another image using Telescope Live data – this was imaged using a super fast and wide telescope from Australia The H-alpha data was extremely high quality, and overall editing this was really fun. I’ve been trying out some new techniques to increase contrast and depth in wide nebulosity fields. and I think it worked out really well in this image. Also, after several iterations of color edits, I’ve discovered a pretty nice way to create an SHO image without using colormasks or other destructive processes […]

Sh2-223, Sh2-224, Sh2-225, Sh2-227 widefield

Sh2-224 is a supernova remnant visible in the constellation of Auriga. It is situated 3.5 ° to SSE of the bright star Capella, the dominant star of the constellation. It is formed by two soft nebulous filaments, the most conspicuous of which is that of the northwest and extends for 20 ‘x 30’ towards the center of the source of radio waves, which has dimensions of 70 ‘x 75’. The object has an unusual shape, with a shell structure with a radius of about 25 parsec, and […]

NGC 2170: The Angel Nebula

Is this a painting or a photograph? In this classic celestial still life composed with a cosmic brush, dusty nebula NGC 2170, also known as the Angel Nebula, shines near the image center. Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a red emission region, many dark absorption nebulae, and a backdrop of colorful stars. Like the common household items that still life painters often choose for their subjects, the clouds of gas, dust, and hot stars featured here […]
