Thank you for the invite nonetheless  |
I take your point, but there are some excellent focal extenders on the market that get you there and don't require anything like a $50k budget. Most larger SCT's, while optically a little slow ( not a biggie with linear response CCD's, just expose for longer) are also a great workhorse. I used a C11 for many years.. the key to success is a rigid and accurate mount IMHO....but that's a topic for another conversation.
