is a piggyback chemical image using Kodak 400, in a Pentax MX SLR with
a 50mm lens set at f3.5,
for 20 minutes and guided on a Losmandy CG-14. I detented gamma about 20%, and increased brightness
& contrast about 5%. Temperature about 35% taken at 11pm, no to slight breeze. Transparency7/10, seeing 8/10.
The Barnard Loop, Horsehead Nebula and Christmas Tree Nebula are well displayed. A short span of
high thin cirrus clouds for about 5 minutes, provided the haze filter to accentuate the brighter stars in this shot.
doing a little experiement here, I just got a G.E. X5 15 meg. camera
and I want to see what is the best
astronomical image it can take on it's own power (optically,which is 15x). Below are shots of the center of
Orion's Belt & Sword. M42 does show up in the medium-field and it's ability to take a sharp image is quite
good, but there are problems. Oct. 17, 2010
This shot was taken in the morning@02:39:49, f/ 4.5, ISO 200, Focal length: 21.8 (4.4x), at the Prospect Ponds,
Ft. Collins. This is the best 30 sec. shot yet. After setting up in Shutter Priority, E.V. +2, AutoFocus-Multi On, the
camera was attached to a rock-solid Losmandy CG-11 star-tracking mount & tripod for stability. The image has
been 'pushed' to the max. by Thumbs+, in contrast. lightness, saturation, gamma, and one 'sharpen much less'
algorithm, but orginal on colors, tint and hue. No Photoshop! 30% res.
Noticable, in this original sized image is the comatic abberation of the lens system. The chip is quite homogenous & clean (dark background,
good color definition, sensitivity) but the camera needs a longer time exposure (30 sec.) and constant focus@infinity. I cannot find out what
chip is in the camera, hence none of the characteristics. Qmax
'Live view' would be magical, wireless connection to i-pad or laptop, wow, but not at this price ($135 -$175- Oct. 2010). I like the chip !!
But that's not to say, the size & weigh is remarkable, very light, but feels SOLID. Nice handling, good on batteries (not the best),
