Lunar processing help(?)

Posted By Bob Schnitzer

James,

Overexposed crater rims, expecially near the terminator are difficult to "process" out. Usually the reflected light from the lunar surface around the overexposed area is much dimmer than 20 degrees away from the terminator due to the low sun angle and will fade to black if you try to expose for the crater rims. Most the the cameras in use now just don't have the dynamic range capability. (Paulo: wishlist item?)

My guess would be to keep your contrast as low as possible during capture. Also, an IR block filter might help if you aren't using one already. Your pics look excellent to me.


Cheers,

Bob

What Do Amateurs Do For a Living?

Commercial Electrical cost consulting has paid the bills for almost 28 years but when I was a kid, Gyro Gearloose provided the model for how I really wanted to live my life. Unfortunately, "inventing" was never listed as a serious career path in any college handbooks. In my spare time I invent add-ons and gizmos for my scope and observatory.

Johannes,

A most excellent image!
May I inquire if your Cassegrain is classical or D-K?

Thanks,
Bob

Superb detail! Just curious, what % of 2400 frames did you keep?

Mars July 27

Paul,

Fantastic image. I could be wrong, but I think I detect some localized dust activity near the meridian. I'm going to give Mars a try tomorrow morning if the haze to my East isn't too bad.

SkYnyx monochrome vs color

Posted By Bob Schnitzer

Jim,

I'm also looking to upgrade to the SkYnyx line, though I'm looking to replace my ToUcam. I spoke with a salesman about mono-vs-color in the SkYnyx 2-1 model and was told that even though the published sensor specs are identical, the color version results in a lower resolution image due to the fact that the color is generated by combining an array of pixels. Paolo Lazzarotti echoed this in an email response to me some weeks ago. I would probably be happy with the 2-1 color model because it would be such a large improvement on the ToUcam. Filter wheel imaging seems almost like a step backward after enjoying the immediate feedback and ease of use of the ToUcam.

There are plenty of SkYnyx users out there so I'm sure we'll get some good feedback.

Wes,

What a superb image! The oblique view and crisp detail combine to give that "in-orbit" feel. Absolutley inspiring.

Wes,

Until you posted this image, it has been my habit as long as I can remember to use my own astrophotos for my Windows desktop on my workplace computer.

Best Science Fiction Movie?

Posted By Bob Schnitzer

Late to this thread..

2 0 0 1 : A S P A C E O D Y S S E Y

I saw it at a Cinerama screen (my college roomate and I sat in the first row to get the full effect). I was in a daze for hours - it fealt as if I had actually gone to the Moon and Jupiter and returned to tell the tale. Had they not been totally engaged in a particularily aggressive hand of 5 card stud, I'm sure my other two roommates would have thought I had suffered amnesia or something. One minute I'm hurtling through space/time and the next I'm hearing: "FULL HOUSE MOTHER-----R!, READ'EM AND WEEP!" That really brought me back down to Earth fast.
