Re: [Utah-astronomy] White light solar viewing with a Herschel wedge
Hey Chuck, I have a 2" Lunt wedge. The wedge comes with in intrinsic ND inside the body (downstream from the partially silvered mirror) and a second ND is attached to the reducer. I purchased mine used. Mine came with two ND filters for the reducer. One for visual and one for photography. The photo ND lets more light through. I've used yellow, green and baader contrast filters in conjunction with the wedge. Each seems to add contrast and aid in sunspot viewing. The Utah Orchid Society has an orchid show the Saturday of our first Winchester outing, so I won't be able to make it. I'll be at the following sun parties though. I'll bring all my toys and we can compare. Bruce Hugo
Turns out there isn't a sun party this Saturday at Winchester, so you're not going to miss anything! See you next month Bruce. On Mon, Mar 16, 2015 at 12:11 PM, Bruce Hugo via Utah-Astronomy < utah-astronomy@mailman.xmission.com> wrote:

Here is a short, but very informative thread on Cloudy Nights, that describes the effects of the Baader solar continuum filter: http://www.cloudynights.com/topic/493918-what-is-the-baader-continuum-filter... This may be my next piece of solar equipment.
Actually Chuck. I was talking about the Sun Party on April 4th. The Utah Orchid Society has our big spring orchid show at Red Butte Gardens that weekend and being President this year... I'm kinda locked into being there the whole weekend. Enjoy the sun without me!
