I’m working my way through the Caldwell Objects in widefield and this is my latest. I was going to do some more, but my filter fogged over.

I spent a bit of time imaging several different things tonight. While the Moon shot came out great. This was probably the best of the rest of the shots. This edge-on galaxy, known as NGC891 is also known as Caldwell 23, which means I’m at least 4 or 5 along toward completing the Caldwell list.

The Rosette Nebula has always been something I’ve wanted to image and tonight was my first effort. Unfortunately, I not only had a serious problem with the autoguiding, but my camera’s battery ran out after only 3 images. I decided to stack them anyway and the result is shown above. Not bad considering, I think…

This was my first attempt at the North American Nebula, also known as C20 or NGC7000. If you look at the image sideways, it sort of looks like the gulf of mexico – actually other images by other people show the shape more completely (plus this is just a part of it – it’s a big nebula!). This was also the first time I tried using a red filtered image added to the full color images. I stacked a bit more than an hour’s worth of RGB from my D50 and then did 36 minutes having added a Red filter on top of the Orion Skyglow Imaging Filter I use. (I recently got a bunch of 48mm filters off of eBay cheaply, this was one of them) After stacking the red images, I added it as a screen over the regular image and it really made the image pop – it’s a bit like a cheapo Hydrogen Alpha filter, combining the two filters. Anyway, I’m pretty happy with how it turned out – the only problem being that the red images didn’t align very well with the RGB image (thus the sort of letterbox formatting).

Tonight was as nice as last night, but again, quite cold. I decided to do some more wide-field imaging with my Nikon D50 using the 2″ Orion SkyGlow Imaging Filter that I got a while back. I think it does a good job of lowering the overall sky noise that I’ve seen, particularly with this camera. I love wide field shots because they show context and this one is no exception to that. The Sculptor Galaxy fills my DSI-II camera almost completely and is neat to image with that, but it’s also neat to see the context of this galaxy.

Tonight I continued to add to the total imaging time on C65 – The Sculptor Galaxy. This is really a neat target to image, particularly now that I’ve got autoguiding working well. Unfortunately, tonight was a bit windy, which meant that I could only do 1 minute sub-images. I’m hoping to have a bit less wind in the next couple of days so that I can get some really long exposures.

Here’s the Sculptor Galaxy image I was working on this evening – over an hour of image data on this wonderful object found in the constellation Sculptor. It’s really one of my favorite targets for my camera. Through the eyepiece, it’s easily visible as a cigar-shaped smudge, but I can’t make out much, if any, detail.
I’m now working on an image of Merope one of the stars of the Pleiades which has a wonderful nebula around it. I’ll post that next.

The Bubble Nebula is a faint target that I was able to capture now that I’m using autoguiding. By using PHD Guiding (Push Here Dummy Guiding) I’m now able to take exposure 2 minutes long (or longer in some cases). This allowed me to get a ton more detail than I was ever able to before. I didn’t even have very good alignment this evening, but the autoguider takes care of that! I’m getting one more target and then I’ll be calling it an evening. Overall, a very exciting evening.

I stayed up WAY too late, but as I was about to pack things up, having spent a lot of time figuring out some technical stuff with my scope, I thought I’d take a look at an object near where I’d been looking and I pointed the scope to C65, a Caldwell Object, called the Sculptor Galaxy. I had never seen this through my scope or camera before. Through the scope, I could make out a cigar shaped blur, but with the camera, WOW! I couldn’t resist and started imaging it. An hour later i finally put everything away, but I was so anxious to see the results that I stayed up to do some quick processing. I’m going to reprocess it when I get the chance, using only the very best frames, which I think will improve it even more, but I’m really excited about this object. I’m planning on returning to it to take a lot more images. It’s a really interesting galaxy where the dust and spiral arms have much more definition than most of the galaxies I’ve imaged. Anyway, very exciting!
