You would get increased resolution, which would be of value for h-alpha but probably not much for sunspots. -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Patrick Wiggins Sent: Saturday, April 03, 2010 3:21 PM To: utah astronomy utah astronomy listserve Subject: [Utah-astronomy] Bino question With the weather being so (relatively) nice today I was able to do my first Sun viewing in a while. Not much on offer in the way of sunspots but several prominences all around the limb including one huge one blasting off the northern limb. I have a pair of 10x50 which I recently equipped with solar filters from Orion. Crisp views. I like the yellow color and they showed last week's sunspots very nicely. So now I'm thinking about similar filters for my 11x80. But would there be any advantage to 11x80 white light views of the Sun over 10x50. More light gathering to be sure but, heck, we're talking the Sun here. No shortage of light even in 10x50. And I can't imagine I'd get that much more with 11 power vs 10 power. But binocular minds far superior to mine live on this list. Hence my question. Should I go with 11x80 solar filters?
