@Uranium235 - You seem to be the SME on this. I've been using the 130PDS for imaging with a Canon 100D for a while a want to move to mono/narrowband imaging so I can actually get out more than once a decade. Considering my budget of around £1000, what would you propose? I've considered a few cameras in this range (the Hypercam 183M Pro Tec, ZWO 183MM pro and the QHY 174M) that all use the Sony IMX178 sensor but fear the pixel size might not be a good match for the optics. I see you've had some incredible results with the Atik 314L +, which although out of my price range Im wondering might be worth saving the extra dollar for. Is there anything in between the aforementioned cameras that warrant a look?
