hey rick,
I tried the star n Her in Hercules, with the TMB 6mm I get an image cross between the 2 I've posted. I think I will have an attempt at collimation tomorrow.
the secondary vanes are pretty much centered on what I'm looking at when defocused a fair bit.
conditions have been clear but it has been windy lately so maybe it could be atmospheric turbulance. Saturn still wavers between crisp and blurryish with the Cassini division just visable .. but its nothing to write home about.
thanks for everyone's help. Doug, I don't think I'm going to repaint the secondary vanes, if anything I'll practice on my old scope first .. but I'm always scared to pull things apart.
thanks again
matt
ps. like earlier the fiery lines protude like \\l// off the star and the rings around it when defocused.
pps. I uploaded a pic of the butterfly cluster, I took with my phone afocally just earlier tonight (at 83x)... its not the best, with vibration and movement taken into account, the stars appear ok?(minus the movement when I pressed the shutter)
