Another reasonable weekend for imaging was had by members of the MAS. I gathered a few more images with the new 40D on the Sky-90. I'm rapidly becoming fond of its particular FOV. This one is of Eta Carinae, the perennial fave.
Doug - I'm finding it hard to decide whether to modify the 40D or not. I like colour, but no more than I like nebulous luminance. Hmm... maybe a second camera (5D or something) should be procured to satisfy the unmodded self, and the 40D should go off to the chop shop for an op.
Yep - the old star/nebulosity balance question. I personally prefer more whispy stuff to dotty, but I think that in this widefield context this ratio is OK too. Thanks for the comment!
Humayun - thanks also. Yes, The Sky-90 is coming along fine I think. I've yet to do some serious star testing and final collimation, but that's become secondary to simply getting out there and using it. I'm delighted to be able to use an f/4.5 scope of any kind, and in this regard I consider the Sky-90 to be my poor man's FSQ-85 for the moment. An FSQ-106 will be on my agenda for later this year, but until then at least I can go out and have some fun again.
I have to say that unmodded it's still a corker. Combined with the f/4.5 optics it rips!
