2 Pallas, the 3rd largest asteroid in the solar system, is now in the constellation Delphinus. It will be in opposition and at its brightest on 8/10. Currently, it is at magnitude 9.4. The brightest star in each image is Saulocin.

A collage of images showing the asteroid 2 Pallas over 3 nights. It is currently in the constellation Delphinus and will be in opposition and at its brightest on Aug 10. Pallas is the 3rd largest asteroid in the solars system after 1 Ceres and 4 Vesta.

Seyfert’s Sextet, found between Hercules and Serpens, consists of 5 galaxies and a long tail of stars of one of them. NGC 6027d is not gravitationally related and is actually 955 million LY away! The other 5 are only 190 million LY away. Such old photons!

#dwarf3 #astronomy #astrophotography

Seyfert’s Sextet is a group of galaxies near Serpens. One of them is almost a billion light-years away!
The image is taken with a dwarf 3 telescope. The total integration time is 15.5 mins, using 30 second sub-exposures.

Enlarged and cropped image of the sextet with NGC 6027d encircled. It is almost magnitude 16 and nearly 1 billion light-years away!

Asterisms named after Fr. Lucian Kemble:

Kemble 1: Kemble’s Cascade (in Camelopardalis)

Kemble 2: Little Queen or Mini- Cassiopeia (in Draco)

Kemble 3: Kemble’s Kite ( between Cassiopeia and Camelopardalis)

#astronomy #astrophotography #asterism #seestarS50 #dwarf3

Kemble’s Cascade (Kemble 1) imaged with a Dwarf 3 scope. It is a chain of stars going from the northeast to the southwest and ends at the open cluster NGC 1502.

Kemble 2 or Mini-Cassiopeia imaged with a Seestar S50 scope.

Kemble’s Kite imaged with the Dwarf 3 scope.

A night sky of wonder and beauty:
a New Moon, a War God hounded by Bees (Mars and the Beehive Cluster), a Thousands Suns next to a seeming Obsidian Void (M9 and Barnard 64)

The Beehive Cluster (M44) in the constellation Cancer next to Mars. Image taken with Dwarf 3 in Mosaic mode.

The Globular Cluster M9 at the center and a Dark Nebula Barnard 64 to the right. The molecular clouds are so dense that the patch of sky looks empty.

In the Great Hercules Cluster (M13), three relatively dark lanes nearly 120 degrees apart seemingly form a propeller. This was first reported by Bindon Stoney in 1850. Globular clusters may look the same but each has its own special traits.

#astronomy #astrophotography #dwarf3

This is the globular cluster M13 taken with the Dwarf 3 scope. A total of 165 30sec exposures were taken and stacked.

We zoom in on the cluster and decrease the exposure to bring out the “propeller” in the core.

The propeller is indicated by the 3 red lines.

I do the same. I search for the nearest known object, image in the same area and look for my target by comparing with an image with the target identified.
