Good morning all,
these are my shots of M82 and M81 galaxys taken over a month with an Astro-Physics 180mm refractor and KAF 16803 camera. Location north-east of Italy. 15 hours in LRGB eeach.
For the H-alfa I took dedicated images with an astrodon Ha 3nm filter. Especially for M82, this meant 90 hours to be able to have good and deep details in the Hydrogen filaments. Hope you will like.

SNAKE NEBULA, THE BLACK SNAKE IN THE SPACE

BEST DETAILS AND QUALITY
https://www.astrobin.com/full/p9gruu/B/?nc=user

Dark nebulae are a show apart, some visible with the naked eye in places with low light pollution, these regions are a type of interstellar cloud so dense that it obscures the starlight in the background.
Dark clouds appear like this due to micrometric dust particles, coated with carbon monoxide and frozen nitrogen, which effectively blocks the passage of light at visible wavelengths.
THESE DUST MOLECULAR CLOUDS PROBABLY CONTAIN SUFFICIENT RAW MATERIALS TO FORM HUNDREDS OF THOUSANDS OF STARS

Capturing large panorama shots like this one are a lot of fun to showcase just how stunning the night sky is from our National Parks. I set out to capture the highest resolution panorama ever captured from Craters of the Moon National Monument in Idaho and I think I achieved that feat with this 77 panel image. The original image was so large it contained over 1 billion individual pixels. If you ever get the chance to explore Southern Idaho I highly recommend the trip. (Modified Nikon Z6 10 second exposures ISO 10,000 at F1.4).

The Grus Quartet (Galaxy) (NGC 7552, 7582, 7590, 7599)

Located in the Grus Constellation, are all 4 spiral galaxies.
Further up we have NGC 7552, the smallest of the three below is ngc 7590, with its mate next to ngc 7599. The most central and most studied of them is NGC 7582.
NGC 7582 is a type 2 Seyfert galaxy, such a classification is due to the fact that the galaxy has an extremely bright supermassive central black hole very similar to a quasar (most energetic objects in the universe). The black hole of NGC7582 is about 10 million times the mass of our sun.

Heckathorn-Fesen-Gull 1 (HFG1, PK136+05) is a very old (~100,000 year old) and extremely faint planetary nebula in the constellation Cassiopeia. It was discovered in deep OIII images by Heckathorn, Fesen, and Gull in 1982 using the emission line survey of Parker et al (1979). The central star is a binary variable pair V664 Cas (13.7 magnitude). HFG1 is the first well observed PN, which reveals a cometary-like structure. As HFG1 moves through the interstellar medium and V664 ejects material, a bluish bow shock is formed and a red long trail of emissions is left in its wake.

Good morning,
I would like to show how astrophotography has changed in the last 10-15 year, achieving results that were impossible even to think 15 years ago.
This is a my shot of the galaxy M82 (NGC3034). As you know M82 is an active galaxy about 12 millions of light years away form us. Previously identified as an irregular galaxy, the near-IR observations done in 2005 found two symmetric spiral arms.

The image was obtained with 30 hours of LRGB exposure plus 100 hours in Hydrogen alpha 3 nanometers to identify better the regions with hydrogen filaments. A careful deconvolution process also on the H-alpha channel permitted to achieve deep fine details.

I wanted to compare my image with the image of the same M82 galaxy but taken by the Hubble Telescope. Of course the HST resolution is much, much higher but considering my telescope is a 180mm from the ground (250 meters above sea level in north of Italy), the result is very good and clearly shows how the new devices and image-processing can now obtain results previously impossible for an amateur astronomer.
