Cheers Paul.
Yes I can see this NB stuff being addictive.
The little SV70 has bad CA so is useless for OSC, so NB it is for the foreseeable future.
I'm hoping to add more Ha data to this, and then have a go with the OIII.

Cheers Marc, and Happy Birthday

Yes the field flattener needs to be tweaked. There is also some tilt in the focuser. The original Stellarvue focuser was not usable due to heavy damage by the previous owner.
I machined up an adaptor to mount a Moonlite but adjusting tilt is tedious as it can't be done in-situ (it must be removed, adjusted, replaced, tested, removed again)
Focus could be better, the Moonlite doesn't have a 10x knob. I also need to finish adding the stepper motor so I can check focus between subs without touching the rig and throwing PHD into spasms.
