Demon Posted March 11 Share Posted March 11 Hi All, I have been working on getting this up and running for a long time now as some of you know. The LB16 (50kg in total including SW80ED etc...) is on a large EQ fork mount that was tracking at 1.5arcsec total. All the electronics are my own and goto is now working fantastically using plate solving to get on target. Nina is talking to Stellarium and PHD2 and it worked last night for the first time reliably for a few hours. I managed to get a second hand but otherwise mint QHY9C camera (-10C, 20 gain, 120 offset), no coma corrector. And this is 20x120s lights, biases and darks. I need to add my own diy electronic focuser as focus could have been better, add a truss light shroud as theres definitely leakage, add secondary dew heater and blacken the sides and back, and get better at collimation (thought I was but nope) and it has previously tracked better (but I changed some settings and made it worse). Plus it has shown spider diffraction spikes previously but got none on this - so guessing its quite a bit off. I also need to block the neighbours chimneys and get a lot better at processing. So while its not a patch on others thought I'd stick it on (just really starting to image with this crazy rig) I am so pleased just to get it working and finally image on target. Also I'm amazed as I think it shows some dust lanes and even a very feint hint of the tiny galaxy at the bottom left just below to the two small stars. Plenty to do to improve and would greatly appreciate your critique (good and bad) thanks very much. 5 Quote Link to comment Share on other sites More sharing options...
