Hi Rolf
That is an excellent image for a non-tracking, unguided instrument when using such short exposures, even though the webcam has been modified. I am impressed by these results – well done.
However, because you have produced such good data, I compared the field to The Sky 6 Pro and I think that the object you have identified may not be Pluto? I think that a “better” candidate is the object that I have arrowed on a copy of your image.
Using The Sky 6 Pro, I think that the object you have identified is a star labelled as GSC 6269:1035 in The Sky 6 Pro:
GSC 6269:1035
Magnitude: 12.3
Equatorial: RA: 18h 19m 29s Dec: -18°12'44"(current)
Equatorial 2000: RA: 18h 18m 50s Dec: -18°13'00"
Source catalog: GSC catalog
Pluto is Magnitude 14.0 according to The Sky 6 Pro.
It is difficult to establish, but I think that the blue star just above what I think may be Pluto is a UCAC 2.0 Star, Magnitude: 14.38 at:
Equatorial: RA: 18h 19m 28.05s Dec: -18°12'41.74"(current)
Equatorial 2000: RA: 18h 18m 48.99s Dec: -18°12'57.84"
What do you think?
Cheers
Dennis
