Managed to do my first (semi) successful drift-alignment for 20 years on Saturday night (following instructions posted on IIS) so I tried a couple of shots through the NG ED102 using a Pentax K-5.
Special thanks to Brad (zardos123) for lending me his field-flattener to test with:
First one is a single 40 second sub of Omega Centauri at ISO 2200. There's still some tracking error (the shots were unguided) but not too bad when the picture is reduced in size.
Second one is of course The lagoon - 3 x 40 second subs at ISO 2200 stacked in DSS. I'm still struggling with colour balance a little in PS.
