Re: New Spectroheliograph construction (based on 102mm refractor)

Thanks Rick! These are beautiful images, nice to compare your CaH and my CaK from the same day. You should try stopping the scope down to say 70mm when you are imaging in CaH.

Re: April 13 2024. Visual Ha.

Thanks for the report JAmes, glad you got a viewing in and glad the sun is nice and busy again. I managed to get the quickest of full disks yesterday, and typically in the early evening when we had prior engagements it cleared up. Still, as I type this the subtle colours of dawn are starting to show...

Went out on an 'over nighter' on a test run last week with my pals after doing a few hours maintenance - new alternator, some new rubber hoses. It was fun! You'll have a lot of fun with your kayak!

Re: Can you stack two tele-centric barlows?

I would have thoght a telecentric is designed to work by accepting a converging light cone to output a telecentric beam. So. if it received a telecentric beam on the input side then this is not the same. I don't know what it would output in this circumstance.

Try it.
