My best Saturn to date

Posted By Alan Friedman
That's really very nice - the sharp definition would suggest the seeing was quite good that night.

thanks for posting,
Alan

Fishing with light tackle - Jupiter w/ a Questar

Posted By Alan Friedman
Hi Paul -

These are wonderful shots. Are they captured at different EFLs or is it the same image resized? I own a Questar also but have not used it for many years. I've saved it in anticipation of years when it will be about as much as I can carry around.

Look forward to seeing more of your images on this forum.

clear skies (and good seeing back home) -

Hi Joe

I?ve been looking at camera options for about two years now.

Don't wait any longer!! The B&W DMK21... would have cost 65 cents a day over the last two years. smile

So reading as much as I could I see that Toucams are used by many folks. I?ve read up on the mods for them with respect to long exposure and changing the CCD chip to the Sony ICX098BL black and white chip. I then looked at the DMK offering that some are using and see the camera also uses the ICX098BL chip. Comments from Alan Friedman would be especially appreciated on this post.
First, I want a cheap camera using this chip. I want to play with the guts and intend on breaking a few of them with cooling. I?m not adverse to buying the Toucam and changing the chip, but the chips themselves appear hard to find off the shelf.
So with this said, anyone have any experience with this item>

I own four cameras - the venerable ToUcam, a Unibrain based B&W board that I assembled into a camera using an altoids box, a Unibrain industrial color camera and the DMK 21BF04. I have not used any of the others since first light with the DMK - it is optimized for noise suppression better than the others and produces a much cleaner image when gain is applied. The Unibrain uses the same chip, I believe, but suffers from an internal noise pattern that is a big problem at low signal levels - I don't believe that this camera has been improved to deal with this shortcoming. The ToUcam is a great value and if you are a tinkerer perhaps that would be a good way to go. It won't take long to recognize the benefits of a monochrome camera and selective imaging with color filters as opposed to white light.

Just curious

Posted By Alan Friedman
Hi Bob -

You won't be disappointed. It's beautifully made, easy to clean and (as with anything I've purchased from Astro-Physics) worth what it costs and then some. As far as I know there is only one 2-1.25" adapter - I believe it adds .25" in optical length.

Jupiter, April 13

Posted By Alan Friedman
Excellent work, Anthony!

What is the elevation of Jupiter at the meridian from you location? With the various obstructions at 24 degrees from my backyard I have about 15 minutes to grab a picture... smile

Excellent shot Richard. This is a favorite area of mine too. I spent some time imaging the moon Sunday night. I wished the seeing had been better but it was a beautiful warm night to be out anyway.

best wishes -
