Description

First light with my 2nd hand tak fs-60 and a borg 0.7 super reducer. Tried 1 hour long exposures for the first time with my atik 383L+... Not sure if it's crazy or cool. This image is made of just three of them with an Ha filter.
Also thx to those who subscribed to my youtube channel... now over 150 and rising.
