This is the other Messier Object I imaged this evening.

I got 5 good frames of M13 in before my camera’s battery died (I actually had 2 bad frames, first of the night – they weren’t horrible, just a little bit of movement). It was actually starting to get a bit chilly outside, so I was fine with going in. Overall a nice night with a lot of success with my new equipment.

Since the viewing was so nice, I decided to stay up and get some images of M13. I had some guiding issues, so I had to throw out more than half my subs, but the end image, looks all right to me.

In addition to the Sculptor galaxy, I also took some images of M13 – the Great Globular Cluster in Hercules. It’s one of my favorite targets visually and with the DSI-II camera. This one shows it in context and inclues a small spiral galaxy in the upper right that’s visible if you zoom in to the large version. Overall a really nice night.

Well, I did some work on my Peltier cooler for my camera and it worked pretty well with one caveat. I added a switch for the fan so I could turn it on and off as desired and I added a rheostat to the cooler so I could set the cooling level. Unfortunately, I don’t think the rheostat I was using is capable of handling the amperage I’m putting through it. It’s okay if I have it at 0 or 100%, but anywhere in between it heats up a lot to the point where I smell something burning. That said, it worked perfectly up until then – I was able to set it at 40% and it maintained the temperature above the dew point, but just barely. What I wound up doing is just setting it to 100% and turning the whole thing on and off to keep the temperature at the right level. I’ll look for a more capable rheostat later this week, if indeed that’s the problem. Any suggestions from electrical folks out there would be appreciated. I’m pretty new at this wiring thing.
Anyway, it’s a nice night and so I took a long picture of the Greate Globular Cluster in Hercules and now I’m imaging some other stuff. Unfortunately, I probably will not stay up long enough to image Jupiter which is too bad because it seems that there is a dark scar found by a regular cloudynights poster that seems to be an impact of some sort. Unfortunately, I’d need to stay up until like 3 or 4 am to image it.

I also got this shot of M13 last night which I thought did a pretty good job of resolving the individual stars.

Here’s last night’s images of M13 added to a bunch I’ve taken in the past for a total of 51 minutes of exposures.

Here’s the Great Hercules Cluster taken with the DSLR. There’s a larger field of view in which you can see a small galaxy in the bottom left that isn’t visible in the image taken through the DSI cameras. But this image doesn’t have as much detail as the DSI images. I plan on taking some longer exposures of this soon hopefully on a less humid night.

I was just about ready to park the scope and put everything away for the night when I noticed that M13 was out. I hadn’t imaged it since the fall (before I got my current scope and camera) and I just couldn’t resist – it’s 12:46am now and I’m just now starting to put stuff away. I’m very happy with this image, though…

Here is tonight’s updated time-lapse image of Comet 17P/Holmes. The comet continues to grow larger and move across the sky. Soon I won’t be able to do the time lapse every day because they will start to overlap one another.
The image below is a 1005 second image of the comet taken this evening.
There’s been a lot of discussion lately online about what happened for the comet to brighten that much. No one seems to have a firm idea so I might as well put in my two cents. I think it was attacked by aliens.
And I thought it might be a good idea to post something other than just comet photos, here’s an image of M13 that I took this evening:
