050916 Mercury transit

Submitted by jimwcoleman

After getting shots of the rare Venus transit back in 2012, I was looking forward to getting some shots of the May 9 Mercury transit, as well. In 2012, it was difficult due to the typical Pacific Northwest cloud cover. That was true today, as well, but I was patient and I managed to get the shots. Another thing that made it difficult was the fact that I was shooting through the trees. What you see in the photos here are not clouds, they are fir needles and branches, making focus extremely difficult.

Preparations for the May 9 Mercury transit

Submitted by jimwcoleman

Tomorrow morning, May 9, Mercury will transit the face of the sun. Living near Seattle, the weather forecast is not promising, but I did just catch a break in the clouds and got my solar equipment dialed in. Sunspots are sparse right now. This is how the sun looked today at 10:20 p.m. UTC over Port Orchard, Washington. Tomorrow, I hope to photograph the Mercury transit. At least I'm prepared.

Shadows on Jupiter

Submitted by jimwcoleman

Last night on Jupiter, there was a double transit, meaning that two of Jupiter's moons cast shadows on the planet. Those are always fun to photograph and as this was my first double transit, I took great care to set up the equipment just right so that I could capture the event. In this photo collage, you can see the moons (Io and Callisto) as they move across the Jovian surface. :)

M104 - Sombrero Galaxy

Submitted by jimwcoleman

Someday I hope to get a real camera ... I feel I am wasting my time with this Orion G3 Starshoot, but it's the only DSO-capable camera I have right now, so I'm stuck with it. Anyway, this is a shot of the Sombrero Galaxy (Messier 104). This is 19 2-minute subs through an 8" Meade LX200R, guided by an Orion ST80 and PHD, stacked in Maxim DL. I seriously get bummed after freezing my butt off and fighting the crappy Orion software for hours only to get an image like this. But it's something.

M64 - The Black Eye Galaxy

Submitted by jimwcoleman

Viewing was horrible in the Seattle area tonight ... the moon was bright and the skies were very hazy - so much so that there was a ring around the moon most of the night. But I was out working on the equipment and managed to eek out a photo ... this is Messier 64, the Black Eye Galaxy, and a favorite target of mine.

04/09/2016 - The boring side of Jupiter

Submitted by jimwcoleman

Here is an image of what is sometimes affectionately called "The Boring side of Jupiter."

As the planet rotates, many of its distinctive feature markings (such as the Great Red Spot) are sometimes turned away from Earth, so all we see is what you see here. Still beautiful, but lacking some of those iconic features we expect to see when viewing a picture of Jupiter.

NGC 2903 - a galaxy in Leo

Submitted by jimwcoleman

Here is NGC 2903, a magnitude 9.7 galaxy roughly 20 million miles away in the Constellation Leo the Lion.

To get this photo, I coupled an Orion Starshoot G3 CCD cam to the prime focus of an 8" LX200, guided by a piggy-backed Orion ST-80 and PHD. Over time, I'm seeing some error in declination, so I limited my exposures to 60 seconds, exposed 50 and stacked only 12. As the image is not as sharp as I would like I would suspect collimation, but the scope was collimated only hours before this photo was taken. Therefore, I suspect tracking/guiding.

Jupiter in better seeing - 04/01/2016

Submitted by jimwcoleman

Here is tonight's effort with Jupiter. This time, I used the same equipment as last night (8" Meade LX200R and a Celestron Skyris 132M) but this time, I added in a Meade 2x Telextender for higher magnification.

Seeing was a bit better than last night, but the image was still quite jumpy. This is 65 percent of 1800 frames, stacked by Registax 6. FireCapture was used to capture the .avi.
