Re: Looping prominence 14th April
Thanks folks, I am really impressed by the amount of detail it's possible to get with the Lunt 60, this was imaged at ~0.71"/pixel. I'm now thinking about a "Marty mod" for it (https://solarchatforum.com/viewtopic.php?t=34331) and I can see a Lunt 100 would make an ideal retirement g...

Wow. F/100. So it turns out you can double up telecentrics. What was the final focal ratio?
