Thanks, Paddy and RobK and Ron,
It seems like we all have our own favourite versions of the Digitized Sky Survey......the online Sky Survey data can be found in several different websites, each with its own unique interface and capabilities. I have probably tried more versions of DSS than most people!
The three flavours of DSS that I have mentioned are the best ones that I know of.
The DSS versions at Aladin and LEDA both give important and unique perspectives on the DSS image of a galaxy, while Wikisky version of DSS provides a lower resolution but deeper DSS image.
Anyone know of an even better version of DSS?
The main limitation on this DSS imaging data is the very modest angular resolution.....I would just love to see a sharper version of DSS!
For the smaller galaxies, in other words galaxies of Blue Magn. > 13.5 , DSS imagery sometimes doesn't cut it, and you might see a very fuzzy image..........often, though, the JHK (J+H+K bands composite)(near-infrared) .jpg image from 2MASS, found in the NED database, gets me out of trouble for some of the fainter galaxies.....these Two Micron All-Sky Survey images are noisy and faint, but they do have good angular resolution.
P.S. The charting software called "Guide" is very similar to the better known "Megastar", but I prefer "Guide" because its popup information boxes are very very rich in data about galaxies.
Undeniably, both of these tools are superb for the really serious deep sky observer.
