Re: Mars 15/08/09 [Re: rolandlinda3]       #3284098 - 08/20/09 02:39 PM Attachment (63 downloads) Edit   Reply   Quote Quick Reply   Kris, I am sorry that I have not responded to your excellent observation of Mars sooner but I wanted to be able to identify the albedo features for you. Your were able to view a good amount of detail over Mars. Thank you for sharing it with us all. As Michael points out, your observation reminds us of the observation made by the French-Italian astronomer and mathematician Giacomo Filippo Maraldi (1665-1729) in 1719. This observation points out the permanence of the major Martian albedo features over time with intermittent changes in certain regions of the planet over time. I look forward to your future observations of Mars.

That is good news on your new scope. ON THE BINOVIEWERS: If you bought them new from Denkmeier, he is really nice about returns. Some people have a real issue with merging images, so you are not the first. I have a reduced problem with binoviewers but it is not bad enough to warrant drastic action. So, you might check about returning them. But if they do not work, by all means opt for something else and sell them. They retain good value because they really are a good product. The best to you....

I didn't understand why till a little while ago when I had my eyes checked. It turns out that one of my eyes is 7 degrees off from the other, therefore I can't easily merge images. It doesn't affect everyday life but it can be a problem with binoculars and binoviewers. Best, Post Extras:       Kris.

(in the bv high power modus) i'm guessing it should be a little easier to look through two ep's with larger eye lenses simultaneously than 2 ortho-peepholes? on the other hand, it hink the exit pupil will be the same if i use the same powers, so it won't do nothing to help? i'm willing to give this a shot, and if that doesn't work, i will sell it, i'll ask but i don't think returning will be easy since it would have to be shipped over again. i can always try to sell it here in belgium and europe though. thanks for the info!
