This page is simply a listing of all imaged objects on my ccd site, by their type ...
If there is more than one type of prominent object in the field, they will be listed separately in their respective categories
Click to go to:
Bright Nebulae, Dark Nebulae, Galaxies, Globular Clusters, Open Clusters, Planetary Nebulae
The Prefix Page is a brief explanation of object identifiers (origin of names)
Quick links to images/information: Aladin previewer (quick look smaller images / links to CDS info); The STScI Digitized Sky Survey (on demand images up to 60' x 60' ); E. E. Barnard catalogue (original dark nebulae plates with Barnard's notes); NGC / IC Project (historically corrected info, mainly for NGC's, with visual description).
Note: Images are generally presented full frame (1530 x 1020 - not cropped). In a few instances, I have cropped an image by 8-15%, due to sequence registration issues

"Class" description found on my pages; from RC3, PGC
Magnitude, if known: blue, visual or photographic. Only galaxies from the RC3 include this information
Size: Major Axis x Minor Axis. For RC3 galaxies, these values are the apparent isophotal dimensions at or reduced to a surface brightness of 25.0 B-magnitude per square degree
Class: for RC3 galaxies, The revised Hubble classification system; for PGC galaxies, four codes;
1) E for elliptical, L for lenticular, S for spiral, I for irregular
2) B if a bar or semi-bar structure is present
3) R if an inner or outer ring is present
4) M for multiple or possibly interacting galaxies

"Class" description found on my pages; from LYNGA, NGC2000 and SKY CATALOGUE 2000.0
A four part Trumpler classification (e.g. 'II 3 r n') where:
Concentration
I - Detached ... Strong concentration toward center
II - Detached ... Weak concentration toward center
III - Detached ... No concentration toward center
IV - Not well detached from surrounding star field
Brightness Range (of cluster members)
1 - Small range in brightness
2 - Moderate range in brightness
3 - Large range in brightness
Richness
p - Poor (less than 50 stars)
m - Moderately rich (50 to 100 stars)
r - Rich (over 100 stars)
An "n" following the richness class indicates nebulosity involved

"Class" description found on my pages; from STRASBOURG, SKY CATALOGUE 2000.0
STRASBOURG magnitudes are 'photographic'; Classification data from SKY CATALOGUE, using the Vorontsov-Velyamino system
1 = Stellar image
2 = Smooth disk (a = brighter toward center, b = uniform brightness, c = traces or ring structure)
3 = Irregular disk (a = very irregular brightness distribution, b = traces of ring structure)
4 = Ring Structure
5 = Irregular form similar to diffuse nebula
6 = Anomalous form
These codes may be combined to describe more complex structures (e.g. '4+2')

"--" after Class means no data from my sources; "?" means Class is uncertain
