Solar imaging
Not so many years ago, having experienced the splendid solar views through several scopes at NEAF, I resisted
the draw no longer and came back with one of
Jim Kendrick's Baader filters. Alas, I had gotten one that was just a
few mm too small, but Jim and company promptly sent the correct size (Thanks for the great service guys!). My
first images were taken quite literally moments after the UPS delivery truck drove off, and the results were very

I was also awestruck with the Coronado Ha setup that Barlow Bob provided outside, and felt the "gotta' get me one
of those" pangs, though the higher cost than white-light filters gave me pause to reconsider. I didn't hesitate too
long though, as imaging friends kept taunting me with the splendid H-a shots they were gathering. Soon, I called
the friendly people at Coronado and my own H-a setup was on order.

My solar observing/imaging equipment consists of the full-aperture Kendrick/Baader white light filter which is used
on an 8" f5.9 Mak-Newt, a Baader Herschel wedge used with an AP160 and AP Traveler, a "double-stacked"
Coronado 90/90/30 setup for the Astro-Physics Traveler, and a pair of PSTs (Ha and CaK). My earliest Ha images
were taken with a 90/30 (single stack) Tak FS128 setup and Nikon CoolPix digital camera mounted to the
eyepiece via a
TeleVue direct coupler. The camera I am currently using is an SBIG11K. For visual observations, I
use the specialized H-a optimized eyepieces and barlow developed by Coronado (Cemax), which preserve a high
level of contrast in both white-light and H-alpha and a
DenkMeier II setup w/power switch & matched pair of Denk
21 EPs.

Both the Kendick/Baader white-light and Coronado H-a systems are a joy to use, and complement each other very
well. Though I am quite the neophyte in this genre, the patience and guidance of others has been a great help.
Herewith are a few examples of the images gleaned from each setup...  I hope you enjoy viewing them as much as
I enjoyed taking them!

Digital SLR images!
To view the sun in H-a is to have a front row seat to the very dynamics that power the distant stars that
fill our night sky... volleys and plumes of super-heated plasma catapulting outwards to be recaptured or
forever escaping, in a dance that has spanned countless millenia as the nuclear furnace burns on.
Venus transit update: I captured 95 Venus transit images, but the
material is still being processed. For a sneak preview, click on the following

Our viewing site in Roxbury CT,  the spectacular "naked-eye"
sunrise with Venus' transit already begun, one of 95 images with a
rush-processing job... also includes an actual sized inset cropped from the
RAW frame, and a video clip assembled from some unprocessed
in WMV format or MPEG format. The low angle of elevation (22
degrees max by contact IV) coupled with wispy cloud activity resulted in
less than pristine conditions, but being able to see it at all was quite a thrill!
