through a bit of clear but hazy sky before going to work this morning....

with a 1800 lines and 1200 lines it was quite good but the contrast is still a bit low...

Also i've just realized but too late that the slit wasnt set properly in the focal plane of the collimator : that's why the h alpha line edges arent well defined and sharp...and so there is a loss of resolution... I'm going to fix that detail later ^^

Again NO Stacking !! so what you see here is what you can actually see when you look through the eyepiece.. There is no enhancement appart a bit of contrast with GIMP software.
