Kent, I used these screws indeed to optically center the reticle within the polar scope itself - as indicated in my original post. What I cannot do is check the centering of the polar scope (and

Rick, the Mach1 is a bit different from the other AP mounts: turning the polar axis does not also turn the polar scope. The polar axis shaft does not reach all the way to the bottom of the polar axis

. . . Hi Pierre, I think you might have discovered the error here. From you description it sounds like you have centered the polar scope in the housing but you haven't checked the relationship of the

I just put in the Files section (folder phenrotay) 2 pics that show how the 3 reference stars are positioned in the PASILL4 after having achieved a good (< 1 arcmin) polar alignment: - PASILL4-1.jpg

Hi Pierre, Well done analysis. Just a basic question though. You noted the position of Polaris was still offset at the bottom of it's arrow marked gap. Is there any possibility of a mistake, and

This can be adjusted by carefully moving the reticle. This is done my loosening and tightening the three small screws that hold the reticle in place. They are found around the barrel foreward of the

Hello all, I am running a Mach1 and experience some problems with my polar alignment scope (PASILL4). I'd appreciate your ideas here. My goal is to use for alignment the PASILL4 only and reach a

Help me to understand. After upgrading the keypad to firmware 4.15 and after favourably checking Status "All system go", in a mount 400GTO purchased in October 2000, the Time, Date,GMT,LST and Photo

Hi Dean, Larry and Group, I am still researching this, but my understanding at present is that the Sync command in the Telescope Control Window of Maxim DL issues a full sync through the ASCOM A-P

Howard or Roland, I will repeat Dean Salman's question of yesterday as there has been no response. What is the relationship of the Sync in Maxim compared to AP's Sync versus Recalibrate? Is it safe

Joe, I'm not sure about lead-acid battery technology or the use of Lithium Ion or Nickel-Metal Hydride batteries in pure EV but my Highlander Hybrid (HH) has a warranty on the HSD including
