Milky Way

Posted By Ed Abel

Hi! I am looking for an annotated depiction of our Galaxy. I'd like to be able to see the relative position of the Sun and various Nebulae, Globulars, Messier objects and the various arms. Anyone know of a web source? Other?
Thanks,
Ed

Sunspot 652 Large

Hi! Between raindrops and clouds this morning! It's been a few months since capturing a spot. I've included a SOHO insert for perspective.
Thanks,

Stainless Steel "J" Bolts

Posted By Ed Abel

Hi! We are planning the construction of our observatory and need a source for the stainless steel "J" bolts for anchoring the AP1200's permanent pier, as well as some other piers. The largest size I've run across is 3/8ths, except for PierPlates which has the 3/4" diameter bolts. Does anyone have other suppliers, please?
Thanks,
Ed

Wes:
Great picture with a wide range of subtle detail!

Can you supply some capture and processing details. Do you use Registax? Other? What are the alignment, stacking and processing settings, if you don't mind.
Thanks,

Hi! It was pure delight (excluding the variable seeing). I've posted this picture on the CCD forum.

Bruise on the moon?

Posted By Ed Abel

Hi! "Bruise": well-named! My guess is that it is part of the Hyginus rill/crater formations in Mare Vaporum. See if it fits with http://freespace.virgin.net/philip.masding/Moon%202.htm

Other estimates?

Ebony Star Questions

Posted By Ed Abel

Hi! I've seen it at Home Depot ($48 for a 4' X 8' sheet), but that doesn't answer your question of the "best place to get...".

Collimation With Web-Cam or CCD

Posted By Ed Abel

Ken:

Use of the Webcam or Video Camera is the easiest way for me to collimate. I am free to stand at the front of the SCT, adjust the collimation bolt(s), and see in real time what the effect is. My arms are not quite long enough for the C-14 to look in the eyepiece and adjust the bolt(s). Also, with my eyes it is MUCH easier to see the monitor screen than the view through the eyepiece.
