Ha solar scan 220923

Post by Alun_H »

Break in the clouds yesterday afternoon allowed me to attempt another Ha solar scan with the Lhires III with 15um slit and 2400l/mm grating,this time with the Evostar 72ED closed to 40mm f/10 and neutral density filter using x8 speed rate to force the scan.

Absolutely wonderful, well done :bow :bow

I would raise the gamma a bit as the contrast is very low and I think you are losing some black details.
