Hi All. I just posted a new image to my website of the Splinter Galaxy NGC 5907. I now have all the pieces working well on the new scope and it is working well. I struggled with the color data because it was collected last night on a full moon and with a gusty wind. I ALSO ROTATED THE CAMERA BETWEEN SESSIONS AND DIDN'T CHANGE IT BACK, SO THE COLOR DATA ONLY COVERS THE MIDDLE OF THE FULL FRAME. BUMMER!! The luminance was collected a week or so ago under much better conditions. The biggest problem with my design of the scope is that the big tube really catches the wind. I may need to construct a retractable windscreen for the observatory, or lower my pier.

I have attached a greatly reduced and cropped version.

Comments and suggestions are welcome.

Another nice shot Tyler, that set up is really working out well for you.

Looking great Tyler - it could probably
even be sharpened a little in those dust lanes.
Well done

Nice Tyler! I have thought of putting up a windscreen too. I thought of something that basically uses the wall to retract/extend from. Put tracks and a piece of plywood. I only get a east/west wind because the peaks of my roof block some of the north/south wind.

Great looking observatory Bill. I will need to do something like you suggest. I wonder if anyone has posted a design for such a setup. I have a shorter pier that I could install, which would help some, but then I would lose some of my available sky, so I am hesitant to change it. Even with the Paramount, my setup just can't tolerate any real wind or the scope bounces all over the place. I suppose a truss design would be less susceptible to wind but I I still think it would be a problem. I guess that is why major observatories use domes.

Thanks Allan. I find I am opting for less sharpening on most of my images these days. Recently, I have been noticing how many images are oversharpened (IMHO) and I find I prefer those with less sharpening. Don't get me wrong... I always do a little high pass sharpening with soft light or overlay layers in Photoshop, but I apply them carefully and always turn down the transparency to soften the effect. I guess my personal taste goes toward less sharpening, especially at the 0.74"/pixel scale I am shooting. Clear skies to you!

Well done. Now for many hours to catch the tidal stream.

Ha! No... I will leave that to others and their automated systems. I would rather shoot a new target and leave the elusive tidal streams to others who are extreme than I.

Thanks Tyler! For my observatory, making it work it wouldn't be that hard. I've looked at images of your observatory and am sure it could be done. You have some nice images come out of that scope. You did a really great job putting it together.

I think the key would be to avoid creating a finger/hand guillotine. It would be nice to include a hand crank for raising and lowering the panels. I may start working on a design.

Thanks Jimmy! I really like this image, and I am just loving the galaxy detail I am getting with the scope.
