NGC3628 LRGB

Posted By Ron Wodaski

This was taken with the ST-10XME on the C14/Paramount ME in New Mexico. Luminance is nine 15-minute exposures; color is two sets of 6:10:12 minute RGB combined with weighting of 1:1.1:1.2.

M16

Posted By Ron Wodaski

This is a single 15-minute exposure of M16. I used my Debloomer to clean up blooms; there were quite a few because of the long exposure.

The seeing wasn't great, a little worse than average at the New Mexico Skies site. But we fixed a problem with voltage in the camera power supply (ST-10XME, the loaner I've been using this week for testing) - it was set a bit too high, resulting in slightly higher noise levels. With the voltage set correctly, this image is low enough in noise that I could apply a little sharpening to make up somewhat for the seeing conditions.

15-minute exposure, C14/ST-10XME on Paramount ME. Guided with the ST-10's internal guide chip using an aggressiveness setting of 2. Binned 2x2.

NGC3628 LRGB

Posted By Ron Wodaski

This was the first test of the corrected voltage setting tonight. I added color that I took the night before (with the noisier voltage setting). This is three luminance images of 15 minutes each (binned 2x2 with the ST-10XME on the C14). I normally like to get at least twice as much luminance, but this turned out OK in that I could do a little sharpening on it. Seeing was a little rough, however.

Color was binned 3x3, and is two sets of 6:10:12 RGB.

M100 LRGB with ST-10XME

Posted By Ron Wodaski

This is another of the first light images after the voltage correction on the ST-10XME power supply. Four 15-minute images in poor seeing, with Lucy-Richardson deconvolution to spruce it up a bit. Color added from a color series taken with the ST-1001E camera a few months ago.

C14, ST-10XME binned 2x2, and Paramount ME. Guided exposures.

NGC5364

Posted By Ron Wodaski

The seeing was especially bad at the time I took this image, but it's such a nice-looking galaxy I thought I would post it anyway. I'm sure there will be some interest in capturing this galaxy in wider-field shots; it has fascinating structure and would make a great color target.

Four 15-minute images with the ST-10XME on C14/Paramount ME.

M104 LRGB

Posted By Ron Wodaski

More first-light shadedowns of the new camera. I got a chance to test an ST-10XME last week, and I was very satisfied with the results, so I went ahead and ordered one for myself. As luck would have it, I ordered a camera with a class 1 chip (standard is class 2), and I guess not many people do that upgrade because I was able to get the camera right away. In early tests, the camera is very low noise (about 15% less read noise than the loaner I tested with) and is providing excellent images.

This M104 image is a median combine of three 20-minute guided images. Color is from an earlier ST-1001E image at lower resolution. ST-10XME on C14, Paramount ME at New Mexico Skies (my remote scope).

Antennae LRGB

Posted By Ron Wodaski

I posted an image of the Antennae a while back, but I took a new set of data with the loaner ST-10XME camera a few nights ago. THe resolution of this version is a little better than the resolution with the earlier image, taken with the less-sensitive ST-10XE (no microlenses).

ST-10XME on C14, Paramount ME. Four 15-minute luminance images; I reused color from the earlier image. Lucy-Richardson deconvolution to sharpen up details.

NGC 5660

Posted By Ron Wodaski

Here's a cute little galaxy that I stumbled on tonight. It has nice structure. I'll need to collect some color data later this week if the weather holds up.

Six 20-minute L images median combined. C14, ST-10XME, Paramount ME. I used unsharp masking to bring out details; for some reason, this image didn't improve much with deconvolution.

NGC3718

Posted By Ron Wodaski

The winds were pretty heavy tonight (15mph+ gusts), but I managed 5 20-minute exposures of NGC3718 anyway. The stars were badly trailed from the wind (about 4-5 pixels worth), so I had to perform surgery to trim them. This do doubt reduced the level of detail on NGC3718, but I'm still pleased to get an image of this one at all.

C14, ST-10XME, Paramount ME

For comparison, here is a link to the image of this galaxy (and some neighbors) taken with the ST-1001E camera:

A very dim planetary nebula: Abell 43

Posted By Ron Wodaski

This is a very dim planetary in Ophiucus. This is an average of two 20-minute images, and you can just barely make out some of the details in this faint object. I couldn't see a trace of it when positioning the telescope; I had to rely on coordinates. It's off center to allow me to use a bright guide star.

How dim is it? It's six magnitudes dimmer than M57 (mag 9 versus mag 15).

ST-10XME, C14, Paramount ME at New Mexico Skies.
