Telescope.SyncTo(Image.RA, Image.DEC) <-- Run this to sync the scope to an open solved image Maybe this will help. This is a script I run after a goto , it takes an image, solves it, syncs the scope to the image and then centers the target. raOri = Telescope.RA deOri = Telescope.DEC Camera.Binning(3) Camera.Start(5) Camera.Wait ra,de = Image.EstimateRADEC ok = Image.FindCoordinates(ra,de,5) if not ok then Warning("Solve failed") : end Telescope.SyncTo(Image.RA, Image.DEC) pause (4) Telescope.Goto(raori,deori) Telescope.Wait pause (5) Camera.Start(5) Camera.Wait Camera.Binning(1) end

Well, good luck with your search for a solution. BTW I see you are using AstroArt I've tried 3 or 4 plate solvers and in my opinion AstroArts solver is by far the fastest. Doesn't it work well for you?

How it works with my SBIG is that I connect the SBIG driver in Nebulosity and the Nebulosity ASCOM in CCDciel . At the 2nd from bottom of the supported camera list in Nebulosity is WDM webcam selection isn't that what you should use with the DMK 51 ? https://www.theimagingsource.com/media/blog/archive/20080502/

I have an SBIG camera, they do not have ASCOM drivers. Nebulosity 4 has a plugin that allows the cameras that Nebulosity supports to be seen as ASCOM cameras. I use AstroArt for imaging but I wanted to try the Polar Align feature in CCDciel and using the trial version of Nebulosity with the ASCOM plugin I am able to use the CCDciel (ASCOM & Indi only) polar align feature. I haven't tried it with the WDM camera in Nebulosity but it does have one. http://www.stark-labs.com/downloads.html

I gave the Polar align feature in SharpCap a real test tonight, I spent a little extra time getting the alignment as close as possible. This still took less then 5 min. I centered M13 and started guiding with Dec. corrections disabled. I let this go for 25 min. and during that time the average error in Dec. remained at .06 pixel. No detectable drift in 25 min. Quite a nice PA tool.

I've tried it twice, it works very well! I only compared it to the accuracy of my Tak EM-200 polar scope. Set the mount down without using the polar scope, polar aligned with SharpCap and then checked the polar scope. Both times Polaris was right where it should be in the polar scope. -Iver
