I set up SkyTools 4 Visual for my Location, Date, Time, etc. and plotted the position of 2023 DZ2 and then took a screen capture and overlaid it on my image (using the bright stars) and it shows a 25 arcsec difference and slight time offset of the trail.
Here is the composite image. I measured the number of pixels using the Ruler Tool in PS CC and multiplied this by 0.357 arcs/pixel and got approx. 25 arcsecs.
Tak Mewlon 210 F11.5 with Tak x0.8 Reducer
Focal Length 2170mm at F10.3 (from plate solve).
QHY268M Pro BIN 1x1 (3.76 microns).
74 x 30 secs
Image Scale: 0.357 arcsec/px
UTC: 2023-03-23T09:46 to 2023-03-23T10:28
I’m not sure if I have made a mistake in one or more of the settings, as previously ST4 has been spot on for all NEO's that I have managed to record.?
Cheers
