In this widefield image of the constellation of Cepheus is a lot to be seen. The familiar targets like the Lobster Claw Nebula and the famous Bubble Nebula, Sharpless 157 and NGC 7635.

But there are also a few surprises to be found, lower right for example is NGC 7538.

And top right is the open cluster Messier 52.

The data was captured during 2 nights a few months ago.

Abereiddy Tower and the ISS
by Mathew Browne, via Flickr / PhotoHound

The International Space Station shining a path through the twilight above the Pembrokeshire coast. This photo was captured through a window of the Grade II listed Abereiddy Tower (which sits on the headland above the Blue Lagoon), while the setting moon gently illuminated the foreground.

I'm a fastidious planner when it comes to my photos, particularly my astro images - these things don't just happen by accident. You've got to look at the weather, calculate the times and angles of the Space Station's passes to see if they are favourable, and finally you have to find a favourable location to shoot it from.

I'd had this shot in mind for a few years, but it wasn't a location I'd want to tackle alone - it is a challenging scramble to reach with camera gear in tow, but thankfully I had a friend with me as a spotter.

A galactic porpoise - NGC 2936

A galactic porpoise - NGC 2936 by William Ostling, on Flickr

All data was taken by Hubble's Wide Field Camera 3 (WFC3)

The Porpoise Galaxy (NGC 2936) is an irregular galaxy located in the constellation Hydra. It lies at a distance of 352 million light years from the Sun and has an apparent magnitude of 12.85.

Located in the region of the sky between the bright Regulus in Leo and Alphard in Hydra, NGC 2936 is currently in the process of interacting with the elliptical galaxy NGC 2937. As a result of the interaction, the galaxy’s shape has been severely distorted into one that resembles a porpoise or a penguin.

Sombrero Galaxy
www.mattdieterich.com
Copyright: Matt Dieterich The Sombrero Galaxy is home to an estimated 100 billion stars. So many stars are in this galaxy that it literally causes dust surrounding the galaxy to reflect light. Amazing to think this bright galaxy is still 29 million light-years away from Earth. Captured from the dark skies at ObsTech in Chile with a PlaneWave Instruments CDK600 and QHY 600 camera. 2.5 hours Luminance and 30min RGB using 3-min subs. Automation via Voyager.

كوكبة الدجاجة by Mohmmad Alobaidi, on Flickr

The little nebula, the Fly, on the left is NGC 1931 and the Large Spider on the right is NGC 417. Both at a distance of about 10.000 light years away in the constellation Auriga. These emission nebula are rich in Hydrogen gas, that’s why they show up so well through an narrowband filter filter.

I have images this part of the sky a little over a year ago too, but this time the nebulae came out much more defined. I’m amazed at the faint spidery filaments which seem to encroach upon the little nebula, it truly deserves its name.

The Cygnus Wall

Part of a larger emission nebula (NGC7000), The Cygnus Wall is a cosmic ridge that spans about 20 light-years. At a distance of ~1500 light-years, this is one of the most concentrated star formation regions in the sky. Most of the ridge is lit by bright young stars, but also partly hidden by the dark dust created by them. The high contrast due to this phenomenon is what makes this an interesting target to image.

GLOBULAR CLUSTER - MESSIER M22 (NGC 6656)

At the age of 38, in 1665 the German amateur astronomer Johann Abraham Ihle, one night observing Saturn, observed cloud-like spots near Saturn, which was approximately 1° and 40’ away. This was the first globular cluster reported in history.
It is a very bright cluster, located in the constellation of Sagittarius, with an approximate magnitude of 5.1 being the third brightest cluster in the sky, second only to Omega Centauri and 47 Tucanae.

In 1986, the IRAS satellite discovered a feature, quite unusual among clusters, the presence of a planetary nebula, only four known globular clusters contain planetary nebulae, the other three being Messier 15, NGC 6441 and Palomar 6.

Two black holes were discovered in M22 and confirmed by the Chandra X-ray telescope in 2012, designated M22-VLA1 and M22-VLA2, but are believed to have others.

Saturn 2021 Opposition, actually almost one day after. The image was taken on Tuesday 08/04 at 04:59am UTC from my backyard in San Miguel, Buenos Aires, Argentina and was the result of stacking and integrating 10 videos of 90 seconds each. The Seeliger effect is pretty impressive both at the eyepiece and in the image, the bands are also nicely seen. The equipment used was a 14" dobson:

A year in the Sun
Started this Analemma project August 5, 2020 and the last image for the year cycle was taken on July 28, 2021
The landscape photo with the Neutral Density filter removed and over exposed Sun was taken on December 6, 2020, day of the years earliest sunset, from Libby Hill Park Richmond Virginia as a 4 panel panorama and aligned with the sun images all with camera pointing 245°SW.
This photo contains 49 images spaced out by 5 to 10 days with a filter for the sun exposures, plus the panorama bringing the total to 50 images.
All images were shot from the same exact location at 4 and 5 pm eastern due to daylight savings using an Atomic Clock app.

Galaxies in Lacerta. KG Observatory, Julian CA.

It's not often that we think of galaxies in the small constellation of Lacerta because it lies in the Milky Way region between Cygnus and Cassiopeia. There is however a section of the constellation that lies outside the Milky Way’s boundaries and approaches the border of Pegasus and it is here that we find the galaxies.

This galaxy group is known as USGC U813. The group comprises of 8 galaxies including NGC 7265, NGC 7264, UGC 12013 and UGC 12007.

NGC 7265 itself is an E/S0 galaxy with an active core. NED currently leans towards giving NGC 7265 a classification of S0 (lenticular). This type of galaxy is normally only found in galaxy clusters so it must be possible that the NGC 7265 group is or has been associated with a much larger group. The distance to the group is approximately 240 million light years. The whole group appears to be associated with the Perseus super cluster of galaxies.

NGC 7265 itself was discovered by Edouard Stephan in 1876 using a 31” sliver on glass reflector whilst NGC 7264 was found by Marth using Lassell’s 48” speculum metal reflector from Malta in 1863. NGC 7263 does not appear to be part of the same group of galaxies. Steve Gottleib in his NGC notes has observed all of the NGC galaxies in this region but they are described as faint and he was observing from high clear California skies. NGC 7264 looks like a smaller version of the classic edge on NGC 4565 in Coma from the images.
