I think this is strange ask.
I planning another narrow-band mosaic run with the Burke-Gaffney Observatory (BGO) in Halifax. Recently completed one with the Rosette Nebula.
The method I used to position the mount for each panel was offsetting.
The BGO allows centring the mount from a known point--I used a particular star--by providing a horizontal and vertical offset. The offset parameter is a percentage value based on the camera field. For example, if I use OFFSET=-35,0 then I'm saying I want an image 35% of the camera field (long edge) to the west (the negative sign) but at the same declination. After some trial and error, I found the horizontal (RA) offset of 75% gave a decent overlap for the mosaic panels.
I believe that SkyTools can tell me the RA and Dec of the centre of each panel in a mosaic. I suppose I could drive the BGO that way instead.
But I'm wondering if ST4I can calculate offsets for me.
Does it do this? Can I extract offset values for the centres based on a common central star?
