Hi all
With a bit of moon about I decided to get out the Baader 7nm HA filter and do a deep HA of Eta Carina Neb. I only stopped when the scope ran out of travel and would have required a meridian flip. Seeing was quite good and no wind to buffet the scope. Thankfully the off axis guider had a separate pickoff prisim that doesnt go through the HA filter.
19x10 mins UV/IR and Baader 7nm HA filter. Modded 350D, 10 inch f5.6 newtonian, off axis hand guided.
