Copernicus




July 25, 2015

I tried my new ZWO ASI L&P imaging camera last night despite breezy conditions and rather poor seeing. This Registax stacked and processed sequence of the 60 best images (out of 500) was taken in B&W mode though a deep red filter with the C-14 at f/7. This software is just amazing and FREE. The red filter was used because all leading L&P imagers maintain bad seeing is not as evident at longer wavelengths. I compared sequences taken with and without the filter and the latter seem a little better. The splatter of really small craters near Copernicus are less than a mile in diameter. I look forward to a night of really good seeing and no breezes!

Seeing tonight was pretty good so I took advantage of the opportunity to do something I have wanted to do for awhile and that is make a direct comparison of a full format image to an HD Movie Stacked image.

The first image, a stack of four prime focus frames, was taken with a Canon 60Da on my 10" f/6.3 SCT. The second image was shot shortly after the first but with the camera set to its HD Movie mode. Image scale was slightly modified to match them. The first image due to its greater pixel count will hold up to enlargement better than the HD image but overall, at this scale, I think image quality is comparable.

North America Nebula



July 21, 2015

Here my latest hybrid image with Bill Burke's gorgeous 1980s vintage AP-150 mm f/8 apochromatic refractor and my trusty TMB-130 f/7. This mosaic was created using 6 x 5 minute stacked exposures shot with the Canon 6D and IDAS LPS-V4 at ISO 3200-6400. The image was stacked Registar and processed in PS-CS6.

An older but goodie - and too good to be left in a dusty old hard drive.

Shot this morning with the D90 at prime focus on the Orion 120 mm. For once I thought I would get up early to view the last quarter.

Last night was interesting as you can see in the photo selection. I wish I could also have photographed the 2 owls that were perched on our roof before they flew off.
