Dennis,
More than impressed, gob-smacked in fact!
Frankly, the way the technology is these days, no wonder it is hard to underestimated what is capable.
What amazes me more is that this is seemingly better than the pro plates available - using CDS's Aladin 5.0. (See attached images of the 2MASS J plate and the DSS2 plate. The central star is GSC 04687-01873.
The USNO B1 Catalogue, seem too indicate the magnitude limit of this image of yours is about 21.8.
Certainly changed my knowledge. Will fix my webpages too.
Congrats Well done!
Andrew
