Last night I set everything up ready and expecting a full nights imaging. Unfortunately the weather gods intervened and in the end limited my testing to just 30mins of which I managed to gather 12mins of good data...! The weather conditions were horrible, intermittent clouds with the thin wispy stuff in between etc... Normally I wouldn't have set everything up but it was promising to be clear??? In the end it ever happend. So here is the first successful test at F10 with the new Mewlon (with corrector baffle assembly) I still have some minor guiding issues but I'm very pleased with the results above; the stars are greatly improved with no sign of coma at all. The coma was never that bad but it was noticeable at the corners even on the ST10 chip. I would say that these stars are as perfect as they can be, give the weather conditions. I now have a telescope that I can guide at 2500mm fl, 3000mm fl was impossible!!! Or too frustrating? It can image the smaller DSO with no coma and hence has become most versatile. (Not just a specialised planetary scope). The next test will be M1 the crab at F7 with the new reducer fitted, most probably after I return from my net business trip.
