Not a bad a repo Trevor the background is darker and less green, M1 though looks a little harsh to my eyes on my little laptop screen. Thanks for the reply Dr Paul and Marc not sure what natural is any more when using nb filters I just used average on the Ha and O111 to create the third channel which I think I used as the green channel. Michael the 18" is playing up again in the tracking I had to throw away 60% of the subs with egg stars, although the tube is going to weight watchers or the tip. Actually I am building a aluminium truss design hoping to save about 15 kg? it will also sport a larger secondary mirror allowing better use of a oag and give the guide scope the flick. Thanks also Tony and Lester and David yes looking forward to spsp, Ian and Enrique said they are coming.
