Made from 48 x 88 sec frames with 6 dark frames. Pentax K3II Pentax DA*300mm f4 on SkyWatcher GTi tracking mount.

Shot taken with a Skywatcher 80ED refractor telescope mounted on my Nikon D500. The resulting focal length is 1200mm (1800mm eq) due to the 2x Barlow lens added to the setup.

Edited in Photoshop to extract the shades of the minerals on the moon soil (just saturation increased in multiple small steps).

89 x frames totalling 8300 seconds or 2.5 hours, Sky watcher Quattro 250 P and QHY 183MC Pro camera. NGC 55, is a Magellanic type barred spiral galaxy located about 6.5 million light-years away in the constellation Sculptor. Along with its neighbor NGC 300, it is one of the closest galaxies to the Local Group, probably lying between the Milky Way and the Sculptor Group. It has an estimated mass of × 10¹⁰ M☉. Wikipedia

The Horsehead Nebula is a small dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, one of the bottom stars in Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex.

This was our longest total exposure, comprising of approximately 15 hours of Ha. R, G and B frames. Captured with the Sbig ST2000xm attached to the Skywatcher ED80.

This is a planetary nebula in constellation Vulpecula, at about 1227 light-years from Earth.

Planetary nebulae are the remains of "dead" stars and are quite beautiful to image :)

Skywatchers are in for an end-of-year treat. What has become known popularly as the “Christmas Star” is an especially vibrant planetary conjunction easily visible in the evening sky over the next two weeks as the bright planets Jupiter and Saturn come together, culminating on the night of Dec. 21. Here, the Moon, left, Saturn, upper right, and Jupiter, lower right, are seen after sunset with the Washington Monument, Thurs. Dec. 17, 2020, in Washington.

This is an emission nebula IC410, also known as the Tadpole Nebula. There is an open cluster in the center of the nebula, NGC 1893. Stellar winds from these young stars sculpts some of the nebula's gas and dust into two tadpoles near the center of the gas cloud.

Last time I tried to shoot this region, it was last year. It took me almost 5 nights to tame the AZ-GTI. This time was clearly easier! It was a kind of revenge :D

I was supposed to shoot during two nights, but after processing the first night, it was clearly enough. (Even with a 90% Moon)

Star clusters, emission nebulae, reflection nebulae, and dark nebulae all make up this beautiful patch of sky. Most of these objects you can't really see with visual Astronomy. But, when narrowband and broadband long exposures are combined, all their beauty can be enjoyed.

Paying homage to Polaris...our friend in the N. Hemisphere! In the old days, when shooting film, I would use my Canon EF, take out the battery, use the mechanical shutter on Bulb setting, and take a single 3 hr photo, on film, to get the star trails....Now, 25 sec exposures, 300+ stacked together for the same effect. ....but that takes up a lot more room on the hard drive!
