Thanks for the heds up Phil, this proved to be a tough assignemnt.
I managed to grab a few frames of 2025 SS5 through intermittent cloud on 2025-09-28, from 8:58PM-9:01 PM AEST.
2025-09-28T10:58 to 2025-09-28T11:01 UT.
Unfortunately, I was not able to Track on the NEO as the software that controls the mount placed the NEO some 4 or 5 FOV’s off target.
However, I was able to GoTo the correct RA and DEC coordinates, leapfrogging ahead of 2025 SS5 and grab these 5x30 sec frames before the clouds set in.
A Plate Solve gave the following for the full FOV
Center RA (2000.0): 23h 50m 50.01s
Center Dec (2000.0): +19° 09' 39.2"
Scale: 0.5460 arcseconds/pixel
Size (pixels): 3124 x 2088
Angular Size: 0° 28' 26" x 0° 19' 00"
Position Angle: 359° 52' from north through east
Mirror Image: No
RMS: 0.32 (X: 0.27 Y: 0.18)
Number of Stars Used in Solution: 47 (100%)
FWHM: 5.22 pixels, 2.85 arcseconds
Celestron C11 Edge HD at F10, ASI2600MM Pro camera. Full res 1920x1200 crop from the middle of the frame.
The star “pierced” by 2025 SS5 is:
Object Name: GSC 1725:1387
RA (Topocentric): 23h 52m 13.7s
Dec (Topocentric): +19° 17' 29"
RA (2000.0): 23h 50m 53.7s
Dec (2000.0): +19° 08' 44"
Magnitude: 13.58
Constellation: Pegasus
Despite the clouds, I continued to play leapfrog and grab sets of exposures but very few showed the trail of 2025 SS5, most were just photos of clouds…
Cheers
Dennis.
