2022年2月25日 · In this article we'll focus on the use of some of the preprocessing tools available in PixInsight 1.8.9, as well as on the generation of a picture showing the pure hydrogen light emission. The dataset comprises images acquired with H-alpha and red filters.

2020年10月10日 · In this video I show to use NINA to imaging The Andromeda Galaxy in LRGB and HA. I also show you how to review your sub and stack them in Pixinsight, as well as a really cool technique of adding...

2016年8月24日 · M31 with Ha - posted in Experienced Deep Sky Imaging: I added 6 hours of Ha to my M31. This was the first light for the Nexdome. My system is now permanently set up in fairly darker site. I cant wait for the new moon. Pictures of the observatory can be seen here. CC is much appreciated.

2021年11月23日 · "Messier 31 is also known as NGC 224 and the Andromeda Galaxy, or as the Andromeda Nebula before we knew what galaxies were. It can be seen by the naked eye in the constellation Andromeda (how appropriate!) and is our closest galactic neighbor located 2.5 Million light-years away.

While the H-alpha image of the galaxy shows its classical appearance with a bright bulge at the center, below we can see the effect of subtracting the continuum light to isolate the pure H-alpha emission line: H-alpha image. Continuum-subtracted, H-alpha image.

2023年8月19日 · Check this reboot of adding ha to M31 LRGB data!

I plan to go deep on the Ha in M31 in higher resolution and cleaner and cross it over to the Milky Way this fall, but will present this as is for now. By the way, with all this new gear, it's been a pleasure to interact with the makers of many new products such as the Rainbow Astro RST-135 and the Pegaus Astro UPB...

In the end I used two passes of Noel Carboni's "Local Contrast Enhancement" PhotoShop action for the core and just a single pass for the rest of M31, blending the two together using a feathered selection. My aim for this image was to try and show as much as possible without the end result looking too processed.

The Andromeda galaxy, slightly different from the usual processing, using Ha and RGB (OSC) data. I reworked a photo taken in 2022 and added some new data from this year. Instead of the usual processin...

2021年9月22日 · For this session, I wanted to shoot the show piece object most observer look at this time of year, M31 - Andromeda Galaxy in the constellation Andromeda. This is a very common object imaged by beginners and experienced imagers.
