View Full Version : Transit magnification

What magnifications would be necessary (not the same as 'suitable') to view the Transit?

I got:

6 x 21
8 x 21
10 x 50
76mm reflector, various powers 30 to 100
105mm reflector, various powers 18 to 110

and all suitably filtered with correct and approved materials.

If I don't have to lug a scope up to the 8th floor lounge to peer thru the window at the horizon, I won't...the filtered 10x50's on the monopod would be so much easier.

Comments? Suggestions? Ads for hominy grits?

Up to you. Personally, I think a projected 10x would be fairly nice, but that's just me. The bigger the better, however.

Of course, for me to enjoy a 10x projection, I'd need to live somewhere other than the west coast... :(

I'm probably gonna be the only one there, so I won't go the projection route...

Still, are a pair of properly filtered 10x50's enough to see Venus scuttling its way across Sol?

Well, I've done sunspot watching with everything from 8x21 to 12x60s, and they show even smallish spots in fantastic detail, and Venus should be quite a bit bigger than those.

Personally, if the transit where visible up here, I'd be rushing my impending purchase of that 105 I have my eye on rather than waiting until fall (no sense having a telescope when the sky's only truly dark 3-4 hours a night...). Bigger is better, afterall.

If you can see spots, you can definitely see the Venus transit. I just wish I could see it. Where I live, I might actually catch a tiny chunk out of the side of the sun. If I'm lucky. I'm right at the point of the end of the egress.

My 25X100 binoc's are a pretty good FOV in my opinion though 10X would be good too.

With my telescope I prefer about 100X. It gets ya updare but things don't get wobbly.

Hope this is helpful. :) :)
