Yeah the C11 was never going to be a wide field scope
The beauty of your 533 (or pretty much any modern camera really) is that you can experiment with EAA using software such as SharpCap. To some extent, it gets around the problem of guiding such a long focal length scope… I mean, it doesn’t really, but with such a combo you’d probably only need to take 15-30 second exposures, which will likely reduce the number of frames you throw away because of tracking/guiding errors.
Agree on the weather. It’s shocking again this week…
