Default M104 Another one

I took this last year. Good seeing this low in the sky is very rare for my location. So I took this even though it was not well positioned. In fact for most of the data collection time the bottom of the objective was shadowed either by the walls of the observatory or a nearby tree I can't trim due to the shoreline ordinance. Also the scope didn't have time to fully cool down. The result of all this is a very odd shape to the faint outer halo about bright stars. Normally that wouldn't show but I dug deep to get the extensive spherical halo about this galaxy that is rarely imaged. As you can see it is really far larger than most photos show.

One data set was used for this image but processed two ways. I processed it first for the galaxy as you normally see it to show the disk and large central bulge. Then I processed it again to show the extensive outer halo. The two versions were then combined to show both in one image.

This is a cropped version of the full image. The full image can be seen at:

Nice processing of the image data. The focal length used was just right for this subject.

This galaxy gets a lot of attention, like a few others, because it can yield such interesting photos.

Rick,

Very nice image. The dust lane is very clear and the bright areas don't overwhelm the image. Wow.

Another stunning piece of work. How you managed that much detail at your latitude is beyond me. The detail in the rim is reminicent of that famous Spitzer image yet you have kept that beautiful glow in the central bulge. Stunning!

Kind regards
Matt

You mean the rim of the galaxy? Many spirals when seen edge on show a strong dust lane dividing them into two halves. This is one of them. Some that have recently been in collisions show really strong dust lanes like Centaurs A that was posted here recently. M104 may fall into that category as well. Otherwise it is hard to explain the huge halo of stars about it.
