Another nice set of DSS for the Pal Globs
In the August 2010 Astronomy magazine (USA edition) I had found a complete collection of nice color DSS images for all 15 Pals which is of value for star field identification. I found this to be very valuable in my quest for these frequently limiting objects.
As for scope size, my 18" from wonderfully very dark skies with the dimmer Pals being near meridian can bag all 15. Once field identification is certain, choosing/trying optimal eyepeices (Delos, ZAO II 6mm) was important to get the convincing spot of slightly brighter background intensity for the real tough ones like Pal 15. Also highly dark adapted eyes under a hood. It took me an hour and a half to study and really detect Pal 15 and that was after at least 3-4 other tries from other sites. Catch that one high up as you can in excellent transparency from very dark skies is my thoughts for Pal 15.
