Tyler - It shows you picked up the written blurb from APOD, but I would disagree - so slightly. Those arms are not loose. The pinwheel galaxy you posted earlier has loose arms. These arms are not fairly tight, certainly not loose . It would also be nice if you posted the magnitude of the galaxy. So the rest of us can get an idea if, with our own scopes, we can even glimpse the darn thing. Nevertheless, your pictures are very sweet. I wonder what twic king you did to "improve" your images. Talk about nit-picking :)
Hi, I think I agree with your assessment of the arms... they seem pretty tight to me. I usually just use a write-up from a recent APOD for my website, and sometimes throw in something from Wikipedia as well. The tweaking I have been doing is not on the images, but rather on the collimation of the scope. It is very easy (5 minutes or less) to collimate a Newtonian for visual observing with the Catseye collimation tools, but it is far more difficult to get everything orthogonal with the 3" Wynne Corrector. It is very sensitive to the mechanical alignment as well as the optical alignment. If everything isn't spot on, the stars get elongated. It is especially noticeable with the luminance filter. The individual colors seem to focus okay, but the full spectrum spreads out a bit. I think I have everything about perfect now, as the stars look pretty round across the entire field, even through the luminance filter. Thanks for taking time to comment.
