| Big richfield refractor | 10 Nov 2004 03:32 GMT | 40 |
A friend and I have been pushing around the idea of a large richfield refractor. We have been looking but have yet to find a 8+ inch richfield refractor. For cost reasons we are not interested in an APO. Does anybody know of a company that sells big acromats?

| Moon & Jupiter | 09 Nov 2004 22:47 GMT | 5 |
One and a half hours after local sunrise and it is interesting to see Jupiter just 1 degree from the moon's southeast limb using hand-held 10x50B. Less than four hours to go to occultation. I have personally seen Venus, Saturn, and Mars do this routine over the years a couple of ...
