Summary
Brian Colville (300mm Schmidt-Cassegrain, Pixcel 237 CCD Camera)
I have attached a first attempt at the images which I took last night. I have 2 sets of LRGB, plus a methane image, but have not had time to process. I will sent them out tomorrow if all goes well. I found that these presented some interesting features ( dark spots in NEB near the following limb) and did not want to delay sending them.
