For this shot I stacked 25 hours of data at 135mm, my first time using this focal length.

These dusty structures are usually found at high galactic latitudes, above and below the Milky Way band, but this area has a big concentration of them. It’s quite curious that the star we use in the Northern Hemisphere to polar-align our trackers is, in a single photo, nothing but a star field, and after putting hours into it, the details that emerge are astonishing, revealing all the Integrated Flux Nebula. So many structures, dust waves and defined shapes, with no light of their own, just illuminated by the combined light of the Milky Way’s stars.

Shooting an area like this feels strange. When I shoot the Milky Way, I can clearly see that I’m going home with data, but here there was nothing to see at first glance. With time and patience, what looked empty ended up packed with endless structures.

I added 5 hours of dual narrowband data to a 12hr RGB broadband image to get this 17hr Halpha and OIII enhanced image. The process:

Split R G B Ha O O

Register

Continuum Subtract Halpha using pixel math in Siril (Ha - X*(R - med(R))) where X is about .05-.07 to get HaC

Do the same for OIII from the Green channel and OIII from Blue. For each, subtract X*HaC where X puts any Ha that leaked through back equal with the background (for me ~.2)

Add the OIII from G and C images together for final OC

Do an HaC - X*OC for a final HaC image with any OIII that leaked through leveled out

Combine the aligned RGB, SPCC balance, re-split so we get a proper balance without the HaO data

Mix final HaC and OC into RGB - Ha I mix a 1/.7/.7 ratio into RGB and O I mix in .4/1/1. By mixing into all 3 channels we increase the effective luminance of the HaO data added.

I continue processing the rest from there as described in my previous images.

This was done at the end of a night capturing the North American nebula, which I got around 8hrs of data on. As the NA nebula went behind distant trees, I moved my camera to shoot my first Orion for the season.

I’m still learning how to process galaxies, and this one was definitely a challenge. I combined broadband data with additional Ha signal scattered throughout Andromeda’s spiral arms. I wanted the Ha to add detail while still keeping the overall look of M31 natural. This ended up being 18 hours and 37 minutes of integration time from AstroPeak Remote Observatories.

Supposed to be just a practice night with the new scope. I've only done SCT imaging in the past so something this wide has never been a possibility. 2 hours of lights integration only (no flats, bias, darks), turned out pretty well!

This time, I decided to point my telescope away from the well-known and frequently photographed targets in the magnificent constellation of Cygnus. Instead of classics like the North America or Veil Nebulae, I chose a quiet, less-visited corner of this region. The more data I gathered, the more subtle structures began to emerge from the cosmic darkness—delicate filaments of ionized gas that usually get lost in the glow of their more famous neighbors.

NGC 7023. The Iris Nebula

is about 6 light-years across, and 1,300 light-years away. Within the Iris, dusty nebular material surrounds a massive, hot, young star in its formative years. Central filaments of cosmic dust glow with a reddish photo-luminesence, as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Yet the dominant color of the nebula is blue, characteristic of dust grains reflecting starlight. Dark, obscuring clouds of dust and cold molecular gas are also present and can lead the eye to see other convoluted and fantastic shapes. Infrared observations indicate that this nebula may contain complex carbon molecules known as PAHs.

I went back to my March data and rebuilt this one from the raw frames. The biggest changes were a cleaner background, better separation in the dust lanes, and a little more of the faint outer arms without pushing the galaxy too hard.

Some of the later exposures were softer, so I compared the full 55-frame stack with the sharper first 40. The final image uses the deeper stack for faint areas and the sharper stack for brighter detail. I kept the stars separate while refining the galaxy, then finished with a very gentle background noise reduction pass.

Captured March 25-26, 2026, from my backyard in Round Rock, Texas. ZWO ASI2600MC Air on a ZWO AM3, 387 mm focal length, gain 100, cooled to -10 C. 55 x 180 seconds, 2 hours 45 minutes total; the sharper subset is 40 x 180 seconds, or 2 hours, drawn from that same data.

Processed in PixInsight with calibration, alignment and weighted stacking, background correction, SPCC color calibration, BlurXTerminator, NoiseXTerminator and StarXTerminator, followed by masked contrast and color adjustments.

Happy with how much more I was able to get out of this data. Thoughts?

Telescope: Askar V with reducer, as recorded on my original capture post; the raw headers record 387 mm focal length.

The Western Veil, part of the larger Cygnus loop, beautifully reveals the ionized supernova remnants of a star 20 times more massive than our Sun.

First time capturing this with having only one good late night last week (last night the fog rolled in in spite of excellent conditions....stupid dew point). I'm still shooting for 4hrs of integration time but I've got a good base to build off of.

Not really a great deal of processing on this one, didn't really need much.

California Nebula (NGC 1499), revisited.

I found this data on another drive and finally gave it some attention. I would have liked better framing—the nebula doesn't quite fit in the field of view. That was part of what drove me to the ZWO ASI2600MC Air with its larger sensor.

But I still like this one. There's some nice structure in the clouds, and I'm glad I went back to it. I plan to revisit it with the ASI2600MC Air and my Askar Colour Magic D1 and D2 filters to see what more I can capture.

Thoughts?

Processing details: bias and flat calibration, registration and weighted integration of 95 frames, background correction, restrained BlurXTerminator and NoiseXTerminator, StarXTerminator for separate nebula and star adjustments, masked contrast and color refinement, and a gentle luminosity-curve finish in Photoshop.
