Solar pics with Three Cameras, one 11" filter and one Refracrtor

16 January 2013

It was a bright and cloudless morning and upon returning home, I was anxious to do some solar imaging - but this time with the 11" Orion full aperture solar filter,
( astronomer.proboards.com/index.cgi?action=gotopost&board=Equipment&thread=3586&post=15649 ) - attached to the 90mm refractor.

Insanity you might say, but I was satisfied with the results. Experimenting with the way oversized filter, it was just too cold and windy to set-up the C11 for some really close-up shots - so I used painters tape to temporarily stick the filter on to the dew shield of my trusty 90mm finder scope. Seemed secure enough, and had three cameras to use this day - The Canon Powershot S3, the Samsung 14mp pocket camera and the Polaroid 8mp pocket cameras. (Those little pocket cameras aren't too shabby really.)

I also utilized the almost forgotten Zhumell 8mm/24mm Zoom 1.25" eyepiece -

...and it worked very well.

This Orion glass filter is superior to the Seymour film filter by a great deal. I could observe great detail, filiments and faculae easily...and even some granulation. Artifacts not evident in the Seymour. Observing at different powers with the Zoom eyepiece, I was surprised on what this little 90mm was delivering. Hooking up the Samsung camera, I was getting decent shots of the solar surface...

I like this post production filter shot...

I find that the Tungsten setting on the cameras sharpen detail better, cutting out the longer red spectrum a bit...

I thinks....that I will get me a 90mm glass solar filter....
