Description

Sep 16th, 2020 – Hercules Globular Cluster (M13)

This one got a nice story, I’ve always wanted to capture this object with my Hyperstar, I did try to capture it back in 2018 but I was not impressed mainly because it was too small for 540mm FL of the Hyperstar and also I only did 15sec subs because I thought it is a bright object and also the Moon was almost full. Anyways later on I discovered that M13 is way much bigger all I need is a longer exposure and higher FL to get sharper stars

At 2020 GLSG, I had the opportunity to capture M13, so I got 30subs 3min each with ASI1600MC-cool and EdgeHD 9.25” with 0.7x reducer which is 1635mm FL at F/7 and boy I was very impressed

I also included a second image which is exactly the same field of view but a comparison between 2020 GLSG and 2018 shot, huge difference and I hope you like it.
