Sharpless 2-155 has a face in it!

Looks like an owl with his wings spread.

Using a reflector on a go-to GEM mount

Posted By Walter Hamler
You are experiencing the non-orthagonality (sp?) problem of an optical axis not being parallel with a polar or even the tube axis. Very common. The offset of the diagonal has nothing to do with it.
The easiest way to correct is to shim the ota in the rings to make the ota/optical axis/polar axis parallel.
Polar align the scope but try to get the polar axis aligned on Polaris rather than the offset necessary for true alignment. With a moderate power ep, ota on "top", home position, shim the ota or rings to put Polaris in the center of the fov. Swing the mount in RA to the east and west side of the mount while observing the star. It should stay in the fov.
If you can, shim the rings at the mounting point to the rail, so that when you rotate the tube in the rings everything remains as close to parallel as possible.

To post or not to post, that is the question?

Posted By Walter Hamler
BS Floyd!! Go right ahead and test, ie, ",make observations", and then share your observations with us!
Isn't that what these "Forums" are all about?

What you see in which scope (size type, etc)

Posted By Walter Hamler
In my 5" Acromat widefield maybe a 2 0r 3 on good nights. Tonight in my 8" sct about a 6 or 7. I have seen 9, but not often.
Tonight Jupiter showed 2 moons only, then one crossed in front so only one was immediately visible. Kinda neat just seeing only one moon!

Very nice Alan! I wonder what altitude above the moon this view would represent?

M27 revisited

Posted By Walter Hamler
I am interested in the Pantone Spyder. How does it work and how difficult to calibrate. Also, how much do they cost?
I am thinking about getting one for use in my regular photo printing.

Intest MN56 - Mount(?)

Posted By Walter Hamler
James, I just purchased a very lightly used Orion SkyView Pro with the polar scope and the RA drive. I have to say I am very pleased with its performance with a 5" f/6.5 refractor.
These mounts are a little over your price point if you get a new one with all the add on's, but either a used one or a new but basic model would fit your needs nicely. I currently also have a CI-700 that I am selling and I felt the smaller mount was essentially as steady as the larger one with the small ota I am using.

My first Lunar Eclipse...

Posted By Walter Hamler
Hey Ivan, great shots for a first timer, even a tenth timer grin
Here is my final shot from last evening here in the Orlando area.
The clouds cleared just in time.

C5 and Vixen Polaris

Posted By Walter Hamler
I don't see why not. As long as the mount has the Vixen style dovetail mount receiver and the corresponding dovetail on the ota you are good to go.

E-Lyra double star

Posted By Walter Hamler
Cool. Similar to one I captured many years ago with a C8 and my then new Nikon 4000 series point and shoot digital. It was uncannily useful for ep projection shots. I don't remember any details, just put the camera to the ep handheld and this is what came out. Oh that it was that easy ALL the time :-)
