Lovely shots Arne! That 60mm etalon is a winner, keep it and never sell it, or, if you do only sell it to me :D :D :D

Thank you very much, Mark!

Replacing the rusted ITF with a new one from Beloptik did wonders for this setup. I've been trying to use the front filter as a double stack for my SolarMax 60 II as well, but are struggling to get good uniformity. I recon there's a learning curve. Anyway, I'm very pleased with the results I'm getting with this SS setup. I'm not thinking of parting with this setup, but If I do I'll notify you if.

Btw. I have ordered a focuser-upgrade for this scope, which I'm really looking forward to receiving as focusing with the stock helical focuser is a pain in the .....

Best regards,
Arne
