Description

> VERSION H : I thought this one was detailed enough to profit from a nice crop. I also pushed a bit more the sharpness, brightness and color correction... That's it until Ha next week !

TECH SPEC :

> 3x 450 sec in O-III ;

> 12x 80 sec in broadband, all @ 3200iso

F Version (6th of may) the above + :

> 18x 75 sec & 8x 90 sec.

Unfortunately, I changed the angle of my framing so that you'll notice a grainier left bottom corner, with no increase of resolution on the galaxy NGC 4217.

Field of view down to at least mag. 17.90
