Jupiter GRS Longitude
#1
I was wondering if there is some way to update the longitude of Jupiter's Great Red Spot in SkyTools 4?

In SkyTools 4.0d Imaging, the current GRS longitude is 289.4° compared to 312.3° per WinJUPOS (the ST4 value can be determined from the Object Information box for Jupiter; take the current central meridian value and subtract the GRS angle). The 22.9° difference between ST4 and WJ results in ST4 showing a current GRS central meridian transit about 38 minutes early. I can't find any way to initiate an update or enter the value manually.

Another glitch I noticed. I like the addition of the "Display Direction Indicator" to charts, with the equatorial version in ST4 showing N and E on arrowed lines connected at a right angle. They are correctly oriented on-screen (in various directions depending on the view and time), but not when printed. With both the print preview screen and a paper printout, N is always parallel the vertical edge and E is always parallel to the horizontal edge, regardless of the on-screen orientation. I'm using a Dell i7 laptop with Win 10 and a Brother wireless laser printer.

My apologies if I missed either of these items in any earlier posts.
