My HUGE Astrophotography Telescope

Full Post: https://astrobackyard.com/explore-sci... The Telescope: https://bit.ly/3CaQToR In this video, I'll use the biggest astrophotography telescope I've EVER had to shoot the glorious M13 star cluster from my backyard. The Explore Scientific ED140 CF APO is an incredible instrument for deep sky astrophotography. This triplet apochromatic refractor has a focal length of 910mm and an f-ratio of 6.5. The final image of the Great Hercules Cluster uses 2 Hours and 9 minutes (129 frames) worth of total integrated exposure time. A special thanks to Greg at Explore Scientific for setting this up. I was not paid to endorse this product! And yes, I have to give it back:) The Equipment Used in this Video: Explore Scientific CF ED140 F/6.5 APO: https://bit.ly/3CaQToR iOptron CEM60 Equatorial Mount ZWO ASI294MC-Pro Astronomy Camera: https://bit.ly/3qqZWzj Baader Moon and Skyglow Filter: https://amzn.to/2s9txML 50mm Starfield Guide Scope + Camera Package Music by Aljosha Konstanty:   / aljoshakonstanty   Affiliate Links: Some of the links in my video descriptions are affiliate links, which means at no extra cost to you, I will make a small commission if you click them and make a qualifying purchase.
