First Saturn Image

Posted By Mike Watts

Here's the first Saturn image I have posted. This was taken Feb 5, 2005 with a CGE1400 and ToUcam. All comments are appreciated.

Thanks,
Michael

Saturn: second image from first batch

Posted By Mike Watts

Turns out I did take some shots with the IR cut filter. Just not at f22.

This shot was at f11. Color seems better than the previous effort, evidently because of the IR filter. I've fiddled with it a bit and don't know how to get any more out of it. Any suggestions?

Thanks,
Michael

Re: My First!

Posted By Mike Watts

Great image Michael. And it shames the images I've taken with my Nikon D70. Such as this one.

There is grainy-ness as it fades to black around the terminator. I would think the D70 is capable of pics as good as the Coolpic, but this grainy look is characteristic of the images I've taken with the D70. I don't understand it or what to do about it. Does anyone know what to do?

Thanks,
Michael Watts

Image of Almach

Posted By Mike Watts

Here's an image of Almach I took on January 26, 2005 at prime focus on my C14 with a Nikon D70 DSLR. This image has been cropped and resized. But if anyone is interested, I will make some measurements on the original and try to figure out the separation.

Terrific image, Eric! Did you resample to enlarge it?

More pier questions

Posted By Mike Watts

I have a third floor observatory that is very subject to vibration. There is no way to run a pier to ground. So I'm looking for ways to improve the situation a bit. I'm thinking of laying a large stone slab on top of a layer of rubber. I will attach the pier to the slab and the combo should filter out the higher frequency vibrations. If this stops or seriously attenuates frequencies higher than my exposure time, it would seem that this would help. Planetary videos using 1/25 or faster should improve, right?

Has anyone tried anything like this? Advice?

Thanks,
Michael Watts

Jupiter from the patio

Posted By Mike Watts

I recently moved my CGE1400 from it's perch on a second story porch down to the concrete patio. The view of the sky is much more restricted because of all the trees, but I think it paid off in better images.

This was taken May 26 at f11 with a ToUcam, 1862 frames of 2051 quickly processed with Registax, Images Plus, and PSP.

If it ever quits raining, I'll try again with increased image scale. Seeing was pretty good that night, so I still think I should get more detail out of the C14. I collimated the scope the next night without noticable improvement. I've ordered an SCT cooler. Any comments or suggestions?

Thanks,
Michael

My first DSO image - Eagle

Posted By Mike Watts

Here's my first attempt at imaging a dso. C14 at f5.5, ST2000XMC single shot color, six 15 minute exposures, taken from NM skies.

Comments and suggestions appreciated!

NGC4565

Posted By Mike Watts

I imaged 8 objects recently from the dark New Mexico skies, and this is probably my favorite of the bunch. I used a C14 at f5.5 with an ST2000XCM.

M51

Posted By Mike Watts

I took this with a C14, ST2000XCM, Optec compensating focuser, and Optec .5 reducer yielding about f5.5. It is a stack of eight 15 minute exposures. I applied cool pixel and hot pixel filters, and then averaged and color converted using CCDOPS. For this first image, I did some processing with Photoshop: curves to bring out the dimmer details and levels correct the black point.
