Finally, after over a week of cloudy nights (and just before the new moon), it has been clear every night. Unfortunately, I wasted a lot of that time trying to image a very faint (as in impossibly faint) nebula. I thought that with the nebula booster filter I could do it, but I think I have met my match. I could spend more time on it, but there is no guarantee the results will be any better. What I need is a faster (focal ratio) scope, that’s not likely to happen.
Here it is, Sh2-224, also known as the Rice Hat Nebula. It is a supernova remnant, very faint, in the constellation Auriga. The first night I tried it I found that I had not centered it due to the fact that I cannot see it in my images. I tried to get it centered by looking at star patterns in Stellarium. After that I spent 4 nights shooting this and this is all I can pull out of the stacked images. There are some fine images of this nebula on the internet, typical exposure times are around 40 hours or more, which is more than I’m willing to do. This one was much easier, the Shrimp Nebula, Sh2-188, a dim planetary nebula in Cassiopeia, about 8,000 light years away. I’ve never done this one before and am happy with how it came out. It is small and with the 500 f4 had to be cropped quite a bit but the image held up well. Here’s one I haven’t tried for a couple of years, the Great Andromeda Galaxy. I think the colors came out well for a change. Another old favorite, M45, the Pleiades or Seven Sisters. It is fun to get good results instead of the tedious collecting of data from faint nebula that may not even produce anything. Another bright and easy nebula, the California Nebula. I used the nebula booster filter for this one. And now some birds, here is a Loggerhead Shrike taking a bath. I’ve never photographed one doing this before. The Red-breasted Sapsucker is still here. I find it interesting that it is drilling holes vertically instead of horizontal, like most sapsuckers seem to. Maybe the vertical holes eventually fill in to look horizontal. That seems to be happening at the bottom of the image. An Inca Dove at Bud Walker Park.
