Mars and Saturn via 80mm refractor

Posted By Joe Bruessow

Great images with an 80mm refractor. It is nice to see Saturn images popping up again too!

Mars photo color question

Posted By Joe Bruessow

I actually found I need the gain up just a little bit.. say 15 to 25% to get good color balance. Have others found the same to be true?

Mars from Michigan 9-07-03

Did a little more work on the image... is it better or worse?

Saturn from Michigan

Posted By Joe Bruessow

Thanks for the compliments Guys! I am happy with the image but have some even slightly better images on the hard drive of my laptop yet.

I took the images with a ToUCam pro through my C14 at prime focus. I shot the 60 second AVI at 5 fps (300 total frames) and stacked the images in Registax with the frame quality setting at 85%. I took the resulting image and did some mild unsharp masking, level and curve adjustments in Photoshop. Hope this helps

Aurora photos from Rochester, NY

Posted By Joe Bruessow

They appear to converge overhead for the same reason that train tracks appear to converge as you look farther away... an "optical illusion" if you will. This is also observed with rays of sunlight that appear to radiate from a point as they pass through different openings in clouds (especially when the sun is low in the sky). The rays are all parallel to one another and headed in your direction... but as you look further "up" the rays in the direction of the sun... they also appear to converge. Hope this helps.

how is this possible?

I thought the same thing when I saw it...

Some advice on an astro-makeover

Posted By Joe Bruessow

Personally, I think there is nothing much easier to set up than an LX200 alt-az SCT... and the accurate goto's and tracking are hard to beat. If your optics are good I think the other options mentioned are not going to gain much for you... especially when you lose the comfort of tracking/ goto.

Indeed, there are better optical choices but I really don't think an 8" scope is overkill. Unless you are just growing bored with your set-up and want to try something different I'd keep what you have... and if the itch is still there get together with someone in your area/ astro club who would be willing to share the views through their small apo or dob from your location.

Orion 80mm ED

Posted By Joe Bruessow

I posted this image a while back but if you didn't see... here it is again. My first color image... ST8 through the 80ED, Total exposure about 2 hours (LRGB). Hey, it's a start. I want more exposure, but skies have been terrible in Michigan... a warm December kept the Great Lakes from freezing... constant lake effect clouds... YUK!

M66 from Kitt Peak

Posted By Joe Bruessow

Holy Cow! The best M66 I have ever seen! Absolutely outstanding! The seeing was incredible indeed... and the processing was excellent as well.

SBIG for C-11/Hyperstar and FSQ wide field?

Posted By Joe Bruessow

The ST10XE... would work. You could use it binned in the SCT, and unbinned for widefield work using a refractor. Actually even the ST7, ST8, ST2000 would work okay.

The problem is with SCT scopes... using faststar or f/3.3 focal reducers. There will not be enough back focus with the focal reducer for color imaging, and the faststar assemble isn't intended for such large obstructions...

The hyperstar from Starizona however is the exception for the C14... if you have a c14 you may be fine.

Finally, SCT's with the 0.63x focal reducer seem to be fine and have no problems.

Hope this helps.
