Just a quick one , I have over the years used , Film and glass and both I liked but last year I grabbed a Lunt Hershell solar wedge and I can tell you these are very good performers , showing more detail at high powers than both full aperture types .
I am more than impressed , yes these are expensive , need polarising filters attached to the eyepieces and can only be used in a refractor ( but that's no problem here now is it ? ).

You got my interest peaked Brian. The Lunt 2" is only $288 and the Baader Polarization filter $54. That's not bad at all. I'm guessing you have never imaged through it? Now the Baader version is $719 and that is expensive for white light. I wonder what the difference in performance is between the Lunt and Baader?

Mike , there are a few members down here on IIS that have the Lunt like mine and a few with the Baadar wedge and from what I can gather there is nothing between them , personally I see the main difference is the Baader has a built in finder . But $400 plus for a finder id over the top . Here is a sunspot group taken a month or so ago , hi tech as usual Windows phone hand held against a TV Radian with my :unt and 127mm f8 Istar achromat .

I had a European custom made 1.25" Herschel wedge, it performed really well. I loved the natural colour of the Sun compared to viewing through an orange or yellow or Mylar'd filtered image. I was able to see some granulosity, that always amazed me. We did a local small outreach near the historical SS Klondike steam ship site a while ago and quite a few people looked through my herschel wedge and FS60 Tak to see the partial Sun eclipse. If I would buy a Herschel wedge today, I would also choose a Lunt 2", merely because of the pricetag. However, I would have to change the Tak fs60 for another scope because there would not be enough backfocus for a 2" Herschel wedge.

Forget the little TAK! Put it on the 150 Istar.
I wish I knew somebody locally that had a 2" Lunt wedge. I would really like to use one before I buy. As far as the difference between the Baader and the Lunt, others agree that visually and photographically there is no difference. In fact, some prefer the Lunt because apparently it's easier to go from a 1.25" to a 2.00" eyepiece as the Baader requires a hex key. Also, the Baader apparently requires significantly more in focus because of the "click lock" accessory.

My 150 mm Istar refractor's tube is short enough to accept binoviewers. I am pretty sure that a 2" Herschel wedge will come to focus too and I would really enjoy showing the Sun spots and granulosity to my family and friends. But first comes the large refractor building project:) Anybody knows if there is an aperture limit for the use of Herschel wedge? I am just thinking about the heat it may generate in a large refractor could melt or crack some part of the Herschel wedge housing or filter?

The LS2HW (2.0") preforms best on refractors with 6” or less front aperture. The LS1.25HW (1.25") performs best on refractors with 4” or less front aperture. As long as you can reach focus for imaging with a standard star diagonal on your night time telescope, you will be able to reach focus when imaging with Lunt Solar White Light Wedges.
From the Lunt web site.

My Lunt wedge has grills at the back and sides to dissipate the heat , it gets quite warm , not hot , so it must be doing its job and I have viewed for hours with my 127mm no problems .
I am yet to try bino viewing thru the Istar/Lunt combo but I will report back when I do , it would be great I would think with the supplied WO 20mm WA's giving a nice 50x .

My good friend just took delivery of a Lunt Wedge. So I will finally get to see how this unit performs. I hope to image through it so I'll report back here how it turns out.
Update: We are doing a "solar event" for the public on October the 4th. So I will setup an Istar scope and the new Lunt solar wedge and attempt to image through it with my monochrome ZWO (ASI120MM).

LMAO~! How quick corporate employees change their mind about solar....... Hey mike, did you even open the skybender yet?
