AR12282 Ha - 16th february
I was messing around today trying to reduce the image scale down from the Quark, at 4.3x native focal length it is just too much, certainly for me in my conditions, so I tried increasing the distance of my 0.5x reducer from the chip to to decrease the magnification factor. As the 3 black and white images show form today it kinda worked, but I had a focal shift of left to right across the image, i'm hoping i've dealt with this and hoping that tuesday gives me some more clear skies to test my ideas further, but, first results are promising. Taken with the ED80 DS quark, DMK31 and focal reduce to give an effective focal length of approximately 1300mm.
