I do use the meridian delay method, but I'll take Roland's word that it does not depend on OTA orthogonality. I did try to think this through very carefully, imagining an OTA that is non-orthogonal

For what it is worth I found it somewhat visible in a widefield from 2004 it isn't a recent formation apparently

Hi All Well, I have had just a couple of chances to use my new Mach-1 mount, once during the solar eclipse of 1st August and two or three times under the stars. In my (perhaps limited)

Hi David, Try moving the dec with just the keypad connected using the N-S buttons. If you get a runaway, give me a call at Astro-Physics 815-282-1513. Mag. 7 skies! Howard

Hi Scott, I know what you mean about the elusive nature of this object. I first imaged it clearly on 19 July 2007 when doing another project and failed to pick it up then. When I noticed it on my

Rick, I've never compared the accuracy of the two - I'm sure it depends on a few variables not discussed here (eyepiece mag, ccd image scale, etc). In my experience both are terrific. Prior to

Hi Dave, Congratulations! I shot this area with my AP160 and U16M just short of a month after you, 1 and 2 August. When I was processing it I sent a quick version to Chris Hetlage for a preview. He

Interesting that this object was undiscovered for so long and then two amateurs independently saw it on their images literally within days of each other. Congrats on your

Hello, all, I tried running my new (used) 1200 / CP2 via TheSky6 this evening. I used a home-made serial cable that I checked and double-checked for correct pinout*, opens, shorts, etc.

HI Roland,   Thank you for responding. I played with it again tonight and finally figured it out.  It's the black threaded part on the Dec axis that the CW shaft screws in to.  It feels tight, but

Hi Guys, I can give you a little chronology on this "new" Bubble if the AIU decides it is indeed a discovery. I imaged it back on 06 July 2008 from the Mount Wilson Observatory using my AP 160 EDF

Dave J posted this on the Astronomy Magazine forums recently: Re: Newly Discovered Cygnus "Bubble" in Halpha Hi, You can find the "discovery" image of the "Cgynus Bubble" on my webiste at

Absolutely Anthony: thanks for the comment. I think I was clear that I did not know who found it first and that I simply had heard about it on Thurs and imaged it Friday... Paul just jumped the gun,

Richard, Now you see why I asked on the Astromart forum! ;-) Anthony.

Hi Roland, I couldn't resist here: The GPS can help you track your kids if they are carrrying around a Mach1 in their backpack. As for imaging, I have not found a use for GPS. Thanks,
