meeting of minds

Posted By Alan Friedman
Hi -

To warm myself from the first snows here I went back to a solar observation from Sept. 11, 2005. I found this small prominence with its powerful upper junction very interesting at the time - an irresistable force meeting an imoveable object?

Yours to interpret and enjoy!

Alan

Sun day

Posted By Alan Friedman
What a rare November treat in Buffalo - three sessions with my telescope in 24 hours -
Saturn in the morning, the sun for lunch and an evening look at mars.

By some odd stroke of luck the sun transited right in the middle of the
electrical wires in my backyard - unobstructed and quite steady in the eyepiece given
the low elevation.

Here is a quick look at active region 822 through my 5" refractor and 90mm H-Alpha filter.

the Big picture

Posted By Alan Friedman
Hi friends -

Here is more of the sun from Sunday. The sub frames in this mosaic were processed in Astro IIDC on my Mac using automated frame selection and stacking - assembly of the mosaic in Adobe Photoshop CS2.

Imaged with my 5" refractor with 90mm filter at f11 - DMK 21BF04 B&W webcam.

The sun was 25 degrees above the horizon at the time.

best,
Alan

saturn round two

Posted By Alan Friedman
A second session with saturn was much like the first. I did use an unfiltered image for luminance this time which gave much nicer signal to work with though fine detail remains hidden in the poor seeing.

10" mak/cass (f45 - 800 unfiltered frames for luminance, f32 for color) with RGB filters and DMK 21BF04 B&W webcam.

best,
Alan

Re: A farewell to Mars (?) and a lunar crater

Hi Robert -

Both images are beautiful. Hopefully you will catch some early evening steadiness - just as nice a time to capture the planets as the pre-dawn calm.

best wishes -

Plato project

Posted By Alan Friedman
I have been saving a nice pile of video taken in during the August lunation of Plato and the surrounding regions to keep me busy during our long Buffalo winter. A recent foot of snow encouraged me to get started - this is the first of the batch.

The project of assembling a large mosaic should take me a long time. The seeing was mostly fair but good at times. I wound up processing this more than I would have liked.

Captured with the 10" mak and DMK21BF04 webcam - 256 frames selected from 900.

dark side of the moon

Posted By Alan Friedman
Hi all -

I just had to share this odd piece of serendipity. I was reading a review over coffee this morning of a new book about the making of Pink Floyd's historic pop album when a beam of sunlight (already a rare item in December in Buffalo) hit a piece of decorative glass in our kitchen window and cast this prismatic display on the newspaper. It is quit a rarity to capture the moon and sun in the same exposure - much less the dark side of the moon! Fortunately my camera was close at hand.

happy sunday -

gassendi in daylight

Posted By Alan Friedman
I came across this image in a collection that I had never processed. It was taken 5 minutes after sunrise on July 31st with my 10" mak at f32. As I worked on it I found I liked the softness brought by the bright sky. Although the resolution is nothing special, the pre dawn calm in the air made this the steadiest image taken that session.

best wishes -

Alpine Valley

Posted By Alan Friedman
Clear tonight but temperatures down close to 0 degrees F and I am too much of a wimp to go outside and do something new sad so I am posting another frame from my mosaic in progress. Captured in fair to good conditions on August 25.

This was a first test of a very nice new feature in a beta version of Astro IIDC (for the handful of Mac users out there) which supports automated multi-region stacking. It will save many hours on this project.

A/P 10"mak at f32, DMK21BF04 webcam with Baader IR pass filter.
