Great shot!

Hi all, First post of an image from the eclipse – Solar Prominence Detail http://www.deepskyccd.com/gallery_images/solar/8Q3A0326_Prominance_Detail_Cropped.jpg AP 130mm F6.3 Starfire EDF

In another post, Howard recommended I try the 'zenith' method for final alignment. Not being familiar with this I decided last night to give it a try. Two nights ago I used TPoint to measure the

Hi David, You may want to post you PHD2 logs (Guide log and Debug Log) in the PHD2 forum (instructions here). We can help analyze the problem from the PHD2 perspective. One of the other PHD2

What exactly is the 'last version' of TSX, version and build #? If TSX is crashing you should turn on the black box recorder in preferences and set it up to send the crash log to SB.

David, I may not be complete help here but I can make a few comments based on my AP900GTO CP2 and TSX. My chip was the very latest one for the CP2 (can't remember the version, sorry) First, for sure

Hi Mark Thanks for your comments and sorry did not answer before, I am just 'closing' tonight's business and doing order in the collected data. About your comments: 1. Yes you are 'almost' right,

I forgot to mention the version of the chip: GTOCP2 rev D

Hello, I'm a new owner of an AP900 GTOCP2 and this is my first in the group :-) After purchasing, the mount immediately joined a remote setup in South of Spain last month. So far I'm still

Hi Howard, I am not familiar with using a star at the zenith for altitude adjustment. Can you point me to a reference on how this is done. For instance, how sensitive is the method to selecting a

Hi Roberto, I have a 3600 running ACP as well. A few things to consider: With a decent sized scope and mount, it's not unusual for big slews to be several arc-min off, even with the best pointing

Hi Craig, The effects of atmospheric refraction change all over the sky - even at the same altitude. For example, using my location here at AP, and using the standard King equation as an estimator, a

This may be as simple as a worm gear re-mesh. It's a simple job on the Mach1GTO This should be the right link for your

Hi Howard, That was one of the first tests I did was to see if the RA correction was valid for other parts of the sky. So far I have only tried in the Eastern side of the sky, but so far the

I have crossed posted this in the PHD2 forum. A kind soul has plotted my graph in terms of RA position and it looks like there is something loose in the RA axis. I will check the mounting plate etc

Oh!, Thank you Sir! I have been very concerned because I have spent amounts of time and been unable to find what is going on. Sometimes we have perfect nights, and next night, all is lost. I cannot

Hi Roberto, I am copying this to my normal work account to give a more full answer. This situation is a bit too complex and unique for the user’s group, although they are certainly always

Hi Craig, You will most likely find that your rate will not work all over the sky. APCC Pro’s pointing and tracking correction will most likely be a better solution. Kudos, however, for

Hi Andy, I have just posted on the PHD2 group on google with the log files. Thanks. Henry

Hi Henry, Could you post your PHD2 Debug Log and Guide Log from the session in the PHD2 forum. We can analyze the logs and check to see if it is related to the mount or if it is something else. Andy
