#1

Post by frant »


Been a while, it has been a shocking year for imaging.
This is a repro of some data from February, been working on some processing here and there whilst putting together a new widefield rig, perhaps that's why the weather has been so bad :)

Sometimes you just have to say that that's a shockingly good image in one year of shocking conditions!
If I could have shot such an (only) image in a year I would be well pleased.
