В первый раз я использовал новый блок питания с мощностью 18 Ач.
The first time I used the new power supply with a capacity of 18 Ah.

Nice !

Good job with that power supply ! I was wondering what was that white ring on the lens, then you mentioned it's for heating the front end of the lens to avoid condensing , nicely done, does it work ?

Hi Michael,
I have not tried the heating collar yet, I`m still waiting for a clear sky.

Best regards, Ondrej
