Thank you all very much for your responses. Sounds like its pretty even between the two but the 163/1600 has a larger user base and the larger FOV, the 183 will theoretically provide greater resolution, and the reported issues with both models are real but manageable
163- FOV for my system will be 2.11x 1.6
183-FOV will be 1.59 X 1.06
This compares with my current CCD FOV of 2.45x 1.63 - as per astrometry.net.- so both will be a smaller FOV than I am used to...
Hmmm.
Thanks again - wonderful to get first hand feedback
