apt pointcraft

[spillage]

Hi All,

 

Sorry I feel stupid asking this but after scratching my head for so long I gave up. 

I can load up an existing image in apt and the run pointsove and this is fine and is solved in around 30 seconds. I can choose the co-ordinates with the cursor on the image.

What I am struggling with is how to I then get the mount to slew to this new position.

I had an image of the owl nebula and surfboard and when I ran this with the co-ordinates from the center of the image it just placed m97 in the centre of the fov.

If anyone can give me an idiots guide that would be really helpful. 

I am right in thinking that I should be able to load an image from the previous session and get the mount to slew to the same position using pointcraft..my head hurts.

 

Cheers

Spill.

Spill,

 

Check the link below, where it is described how the action you intend to perfrom (What I am struggling with is how to I then get the mount to slew to this new position.)

should or may work..

I did what you are wanting to do this last weekend...with ~3 months hiatus so it wasn't too painful to remember.

What i did was connect both the camera and mount to APT, I had previously synced the home position so the mount knew roughly where it was pointing. I then did a GOTO to M81. Then took a quick image and solved it (I chose blind solve but chose "<<Scope Pos" to give it a rough starting point). Once solved I synced the mount to where the mount was actually pointing.

After that I loaded up my previous M81 image into APT and did a blind solve on it (you can actually save the object and it's position for later use but I didn't bother). After the reference image has been solved you then select that as the new center FOV by clicking on the "<<Solved" button to transfer the coordinates of the reference image.

Then press GOTO++.

Well that is what I did and it got me to within 3 pixels after 1 iteration (as the mount had been previously synched).

Hi. It's: load last nights image - solve - << solved - goto++. HTH

Thanks for all the info. I only discovered this part of apt the other night so I have not really had the time to work it all out. I have only just stripped down all my gear so once I have set it back up and have some spare time I will have another go.

cheers
