Andromeda Galaxy System

Having not had a lot of telescope time during the summer months, I find myself reprocessing data collected in the past. This is a reprocessing of the Andromeda Galaxy region including insets of the two brightest satellite galaxies, M110 and M32. This is from data collected from 2015-2016. The wide-field view was collected using a Canon 6D and 400mm lens, the inset images were captured with my Meade 12” LX90 telescope.

Messier 109 – A Barred Spiral Galaxy in Ursa Major

Messier 109 is a barred spiral galaxy located in the constellation Ursa Major, it is about 84 million light-years away it has a magnitude of 10.6.

Tech Specs: This image is composed of 50 x 60 second images at ISO 3,200 with 5 x 60 second darks and 5 x 1/4000 second bias frames using a using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount (ASI290MC and Canon 400mm lens for guiding).  Imaging was done on March 23, 2017 from Weatherly, Pennsylvania.

This 20-minute wide-field view was taken on March 22, 2017 using a Canon 6D, Canon EF 400mm f/5.6L USM, and an iOtron ZEQ25GT mount. 120×10 at ISO800 and f/5.6.

The Cigar Galaxy and Bode’s Galaxy in Ursa Major

Here is a combined view of the Cigar Galaxy (M82) and Bode’s Galaxy (M81) taken during imaging session in February 2017.

Tech Specs: Bode’s Galaxy (on the right) composed of 53 x 60 second images, Cigar Galaxy (on the left) composed of 28 x 60 second exposures. All at ISO 3,200 with 5 x 60 second darks and 5 x 1/4000 second bias frames (captured using BackyardEOS software) using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Guided using an ASI290MC mounted on a Canon 400mm f/5.6 lens using PHD2 software. Imaging was done on February 20 and 26, 2017 from Weatherly, Pennsylvania. Manually aligned.

Messier 81 – Bode’s Galaxy in Ursa Major

Here is a 53-minute exposure of the large spiral galaxy known as Messier 81 (M81 or Bode’s Galaxy). It is referred to as Bode’s Galaxy as it was first discovered by Johann Elert Bode in 1774 and later picked up by Messier and added to his catalog. The magnitude is listed at a bright 6.9 and the distance is about 11,800,000 light-years.

I was particularly happy with capturing some of the dust clouds on the inner spiral arms during this imaging session, hoping to add more data on a later date.

Tech Specs: This image is composed of 53 x 60 second images at ISO 3,200 with 5 x 60 second darks and 5 x 1/4000 second bias frames (captured using BackyardEOS software) using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Guided using an ASI290MC mounted on a Canon 400mm f/5.6 lens using PHD2 software. Imaging was done on February 26, 2017 from Weatherly, Pennsylvania.

The Sculptor Galaxy (NGC 253) in the Constellation Sculptor

Here is an image I took on the evening of December 27, 2016 of this large, but faint galaxy called the Sculptor Galaxy (also known as NGC 253, Silver Coin or Silver Dollar Galaxy). This was my first time imaging this galaxy and I couldn’t believe how large it was, nearly filling the camera view (I’ve been imaging planetary nebula, so left the focal reducer off). With the high winds and clouds rolling in, this is what I ended up with.

Tech Specs: This image is composed of 68 x 15 second images at ISO 5,000 with 5 x 15 second darks and 5 x 1/4000 second bias frames using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Imaging was done on December 27, 2016 from Weatherly, Pennsylvania.
