Problems revisited

Well, I am out checking the DOB for astigmatism and other aberations again and am pleased to note that it has none of the problems it used to have.
I am using a 12mm Nagler and a Big Barlow (310X)to check out Mars and despite poor viewing with a lot of air turbulence above the image is not bad at all. Some details and the cap are easily seen.
I will be trying the 4.7mm & 6.7mm UWA with the Barlow to see just how far I can push the power before the image falls apart.
The weather has not permited me to check it out much since I remounted the diag mirror. But it certainly seems the astigmatism was all in the diags being mounted with apoxy!
I will let everyone know how the evening has gone later.
I want the mirror to achieve equalibrium before I make a real report.
The 2 fans are really working well though and the upper fan is sure taking care of the hot currents from the mirror.

Well, all seems to be right with the optics now. I had a chance to check it out pretty well and found no problems.
The best magnification with good detail qas 310X. The best magnification with a little detail was 950X, but the view was deffinately soft at that mag. 555X showed some details on Mars with some degrading of the image.
I had a lot of clouds drifting through and a bit of upper level cirrus that was interfering. Also a bit of upper level air turbulence was evident in the star tests.
Over all I think with the conditions as they were the scope perfromed up to specs.
I appreciate all the help everyone has given with advice on my problems. There were a few bugs along the way, but the diag mirror mounting was the worst of the lot.
The Swayze mirror now gives views that meet with the expectations surrounding the name.
The fans are deffinately the was to go. I would advise anyone to give them a try.
the Lasermax Colimator has been a great help in finding the optical path.
Just hope that the weather gives a few good nights this month. At least a few before the year is over!
Dark skies to all,
Floyd
