It is always interesting to reshoot a previously imaged target to review where one's processing is.

I hope my current level shows a bit more of a natural look whilst still pulling out as much detail as I currently can.

Guess you will decide that though ;)

This image was rendered from the same data set that was used for the North America nebula image that was uploaded on 2025-07-09. The difference was that I used synthL in the July image, but I did not use synthL in this image. After studying synthL in situations like the present narrowband image where a dedicated luinance filter is not available, I came to the conclusion that synthL does nothing boost image quality in the same way that luminance does when using a luminance filter as part of an LRGB filter set, and processing the luminance master image in a manner that emphasizes sharpness, contrast, and noise reduction. The only way to get a similiar boost in image quality is to accumulate more integration time through the three filters in the SHO or RGB filter set.

Here is a link to the YouTube video that convinced me that synthL does not boost image quality.

IC443 is a Galactic supernova remnant (SNR) in the constellation Gemini. On the plan of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth.

IC 443 may be the remains of a supernova that occurred 3,000 - 30,000 years ago. The same supernova event likely created the neutron star CXOU J061705.3+222127, the collapsed remnant of the stellar core. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.

Despite 92% moonlight, I was able to capture Comet Lemmon relatively easy although it was somewhat washed out.

I used a Fujifilm X-T5, Nikkor 180mm f/2.8 lens @ f/5, iso 3200, exp 28x20s. Stars and comet are fixed by overlaying stars and comet separately in PixInsight. Field of view is ~7.5x5 degrees. Brightest star lower left is Psi Ursae Majoris (Psi UMa, ψ Ursae Majoris, ψ UMa) @ 3.01 magnitude. Comet's tail is at least 3.5 degrees in this image. The star 1.4 degrees above the comet is Omega Uma at 4.6 magnitude.

LDN1235 nebula is a reflection nebula in the constellation Cepheus. It is so thick with interstellar dust that it blocks most of the light from the stars behind it.

It is also known as the Shark Nebula, because of its resemblance to a shark, with a distinct nose, dorsal fin and tail fin.

This cropped image of Comet Leonard near M3 was taken (3 Dec) with a Fujifilm X-T3, Nikkor 180mm f/2.8 @ f/5.6, iso 3200, exp 80x60s. Post-processed in PixInsight and Photoshop. Taken between 3:12AM and 4:46AM under very thin broken clouds and some wind.

Of note: Attempts taking 120 second exposures proved useless due to the comet's relative rapid motion. In the coming days, I'll be forced to take ~30s exposures with higher iso.

NGC 281 a.k.a. Pacman Nebula

…………………………..

Discovered nearly 130 years ago by E.E. Barnard, an American astronomer, NGC 281 is an emission nebula that spans nearly 100 light-years and is located about 9,500 light-years from Earth in the constellation Cassiopeia.

NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character.

Although it is an emission nebula, the Pacman Nebula is bright enough to be seen with a medium-sized telescope, preferably from low-light locations.
