I shot M13 Saturday night with a canon 20Da, on a 4" APO mounted on a AP900. The shot was 10 minutes unguided at ISO 1600. It is not processed and only cropped...
I have a new AP900 and I would like to use the PEMProAP software. I want to know what the minimum software and camera requirements are to utilize PEMProAP...
... Yes you need one of listed camera control software packages. PemPro only analyses the results produced by the guiding portion of one of the above packages...
... Steve, Good result for a first shot. My comment has to do with the guiding (or lack there of). Without being absolutely perfect on the polar alignment,...
I have a used AP900 and have been using PEMPro to measure and correct the periodic error. I'm getting a periodic error out of PEMPRo of +5.5/-6.4 with an RMS...
First let me state that I am in no way connected with the conference or planning of such event. I am merely an imager that wishes to get as much out of imaging...
Steve -- Any idea what caused the little "tails" at 7-O-clock on all the stars? I assume field rotation would be more uniform. Perhaps the mount got bumped...
First, thanks to all who've taken the time to examine the image. Jeff those tails are the item that most perplexes me. I was careful not to jiggle the mount at...
In a message dated 5/2/2006 9:45:50 PM Central Daylight Time, craig@... ... How old is the mount? When was it purchased? Roland Christen [Non-text portions...
Steve -- Hopefully some of the more experienced folks will chime in. I haven't even started imaging yet, so I'm even more in the dark than you. (Another thing...
I've added a short movie to my web page illustrating the rapid motion of 73P-B against the fixed star field. It comprises 7 six- minute frames during which...
... I have a similar dilemma with the AP1200GTO expected some time next month. Although I also observe, the bulk of my work is indeed astrophotography and I...
Hi Anthony, I find the 900GTO and AP160 are just right for visual use on a 48" ATS pier (using an adjustable chair). The eyepiece height at zenith is not too...
Hi. I got my new AP900 i the middle of Aril and last night it was clear so I did take my first test pictures. I trained PEC with PemPro some days before and i...
I have my 160EDF on a 900GTO with 54" pier. At 6'2" tall I find this a good match - I am particularly annoyed with too low eyepiece poistions which is why I...
I decided to explore my AP900 a bit, cleaning out and replacing the old and dirty grease on the RA worm and components. I came across a couple of interesting...
Being totally new to German equatorial mounts (AP900GTO is coming...), do I need to have the pier in precise level in order to succesfully polar align my...
I know everyone will be eagerly awating to see the AP products diplayed at their NEAF booth by Marj and Roland in their first visit there, especially for those...
If you are going to do your alignment with a drift method there is no need to level the pier at all. With a GE mount, as long as the RA axis is aligned with...

... Ajai: Not exactly true. Yes you can polar align any mount without the mount head being level, but it will take you longer. If the mount head is not level,...
Agreed. Not being level does force you to adjust both axi. But once you are polar aligned it makes no difference whether or not you are level. Ajai ... From:...
Just a quick note about how well my AP1200 tracks. Although precise tracking isn't strictly required for webcam imaging of the planets, it is nice to not have...
Hi Craig. I have a 2003 900GTO and Pempro mesured the error at 8 arc seconds peak to peak. The curve was also very smooth. However, after pec training the...
Hi, all, I found your site after going over information about the Celestron CG-5 motorized mount, with the GOTO hardware. I've been considering purchasing the...
Hi Karl: Sounds like what you want is a mount that will move the camera up and down and side to side, right? That would be rectangular coordinates, ie,...
Somewhere on the Astro-Physics web page discussing the AP900GTO, it states that the current factory specs are 7 arc-sec peak to peak. I think the AP1200 page...
Actually with the GTOCP3 controller on the latest mounts, I think one could do this with the mount set up with the RA axis perpendicular to the earths surface...
