Demon Posted March 17, 2022 Share Posted March 17, 2022 (edited) Hi All, This may be slightly disappointing as I've just received them and I am waiting for a clear night - so sorry no images yet. I've bought a ZWO ASI178MM from FLO and Astromania 9x1.25" manual filter wheel with LRGB and Ha filters over Amazon. I cant afford a bigger sensor or higher quality filters or motorised wheel so will see how it goes. It will initially be used with a SW 80ED doublet that I got second hand. I'm just motorising the manual filter wheel with a cheap stepper motor and GT2 belt which looks like it should be pretty easy as the belt fits in without any mod and already got an Ascom Arduino driver working for it and tested with APT already and a stepper ready. Also likely going to fit a peltier and fan to back of camera. Its pushing the pixel scale but am going to try lucky imaging with shorter exposures to hopefully get the quality up with selective stacking. I'm really looking forward to trying a more sensitive system and having access to Ha etc. as my previous was an unmodified Canon D50. I'll hopefully update this before the end of this year with more relating to the actual cameras performance (likely starting with M81 & M82) - heres hoping for some nice clear night. p.s. I was going to try it with my light bucket but I've had no end of collimating and atmospheric issues, so taking the easier option for now and staying wider field - especially with the small sensor - usually used for planetary or solar but seen great results, even overcoming the amp glow - yes will also try some longer exposures also but really sick of the atmosphere and want to eventually go big for small targets with lots of shorter exposures. p.s. I got my mount tracking better recently by simply tightening up the clutches, but also got plate solving working beautifully so I can now easily get on any target with APT linked to Stellarium - which is so fantastic and has given me the biggest boost I've been needing - especially for those better straight up targets. Best wishes & clear skies, Nick Edited March 17, 2022 by Demon 2 Quote Link to comment Share on other sites More sharing options...
