M13

[The Admiral]

This is essentially first light with my new light-weight gear, including the newly delivered ZWO AM5 harmonic mount. It took me a while setting up, as all of the equipment was unfamiliar to me. It was also my first experience with a cooled astro camera, rather than a DSLR.

This was the set-up.

• ZWO AM5
• ASKAR FRA400 f/5.6, at native FL.
• ASI533MC camera
• Astronomik L2 UV/IR filter
• William Optics 50mm/200mm Uniguide
• ASI120MM guide camera
• ASIAIR Plus

60x60s lights, with flats, flat-darks, and darks. Processed in APP, final polish in Lightroom. Slightly cropped. Taken on 09 July 2022.

 

 

IC4617 is a Seyfert 2 galaxy, but I haven't managed to find out what its distance is.

Beautiful! I love that you can see that tiny IC4617 galaxy, the resolution and detail is brilliant.

The redshift is 0.03649 (10) according to SIMBAD. Pop over to https://www.astro.ucla.edu/~wright/CosmoCalc.html and find out that it is around 155 megaparsecs or about 500 million light years.
