Smile Siebert Barlow finally arrives...

Well after 79 days of waiting it finally arrives my Siebert 1.25" 3x Barlow. These images were taken at about 10am on the 26th of July, 2006

OKay #1 is of an approximate naked eye view looking SE from my backyard. I have magnified a small portion of it to show what I am taking a pic of used 3mp mode on Fuji finepix S-7000.

#2 is of the object through my TAL-1 4.3" f7 scope. Taken with a Phillips Toucam 840K, 10 second AVI, reprocessed in registax and colour corrected, aligned horizontal and colour corrected in Paint Shop Pro.

#3 is tha same view as above, processed the same too, but I have added the Siebert 3x Barlow. What a difference . and excellent resolution with no CA visible.

The magnification of the Barlow I worked out to be 3.0506329113924050632911392405063 times, Give or take a few decimal places.

Ooops forgot to add that the images through the telescope have not been resized with software, they are as-is off the toucam which was 640x480 resolution. Only editing was straigtening of the powerlines to make them the same. Which resulted in a cropped image. So what I saw on the laptop is the same as what you see here. Image looks a little blurry because the thing was moving about in the wind and heat refraction was affecting it.
