A prolific star-forming region, lying 5000-6000 years from Earth. M20 - The Trifid Nebula13 viewsA combination of an open cluster of stars, an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (which accounts for the gaps dividing the nebula into lobes). About 5000 light-years away in the constellation Sagittarius. M20 - The Trifid Nebula11 viewsA combination of an open cluster of stars, an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (which accounts for the gaps dividing the nebula into lobes). About 5000 light-years away in the constellation Sagittarius. M27, The Dumbbell Nebula10 viewsThe first planetary nebula to be discovered, the Dumbbell is 1227 light-years from Earth in the constellation Vulpecula. M42 - The Great Nebula in Orion9 views1344 light-years away, 24 light-years across, this emission/reflection nebula is one of the brightest in the sky, as well as the closest region of massive star formation to Earth. M42 - The Great Nebula in Orion10 viewsAnother take on the Great Orion Nebula, incorporating hydrogen-alpha data. M42 - The Great Nebula in Orion2 viewsA narrowband image of the Orion Nebula, captured with a one-shot color CMOS camera and an IDAS NBZ nebula enhancement filter. M78 - Reflection Nebula in Orion4 viewsM78 - Reflection Nebula in the Orion B molecular cloud complex, 1,350 light-years from Earth. M97 - The Owl Nebula5 viewsPlanetary nebula in the constellation Ursa Major, 2030 light-years distance from Earth and about 8000 years old. The blurred appearance results from the fact that it consists of several overlapping shells of gas. The shells are not entirely concentric, but form a barrel-like structure which gives rise to the owl-like appearance. NGC 1499 - The California Nebula12 viewsAn emission nebula in the constellation Perseus, so called because it resembles the State of California in shape (though not in this image). About 1000 light-years from Earth. NGC1499 - The California Nebula, narrowband version6 viewsThis bizarre rendition of the California Nebula was the result of an unrepeatable experiment in mapping H-alpha and O-III to various channels in a mad orgy of improvisation. NGC1499 - The California Nebula, narrowband version 6 viewsA more conventional narrowband rendition of the California Nebula, mapping H-alpha to gold and O-III to blue 67 files on 6 page(s) 1 2 3 4 5 6 Debug Info  Debug Output: show / hide Select All USER: ------------------ Array ( [ID] => 71b638929a48ea267567a74cfc488db9 [am] => 1 [liv_a] => Array ( ) ) ========================== USER DATA: ------------------ Array ( [user_id] => 0 [user_name] => Guest [groups] => Array ( [0] => 3 ) [group_quota] => 0 [can_rate_pictures] => 1 [can_send_ecards] => 0 [can_post_comments] => 0 [can_upload_pictures] => 0 [can_create_albums] => 0 [pub_upl_need_approval] => 1 [priv_upl_need_approval] => 1 [access_level] => 3 [disk_max] => 0 [disk_min] => 0 [has_admin_access] => 0 [group_name] => Guests [can_create_public_albums] => 0 [can_see_all_albums] => 0 [group_id] => 3 [allowed_albums] => Array ( ) ) ========================== Queries: ------------------ Array ( [0] => SELECT name, value FROM cm_config [include/init.inc.php:177] (0.21 ms) [1] => SELECT * FROM cm_plugins ORDER BY priority [include/plugin_api.inc.php:48] (0.15 ms) [2] => SELECT MAX(group_quota) AS disk_max, MIN(group_quota) AS disk_min, MAX(can_rate_pictures) AS can_rate_pictures, MAX(can_send_ecards) AS can_send_ecards, MAX(can_post_comments) AS can_post_comments, MAX(can_upload_pictures) AS can_upload_pictures, MAX(can_create_albums) AS can_create_albums, MAX(has_admin_access) AS has_admin_access, MAX(access_level) AS access_level, MIN(pub_upl_need_approval) AS pub_upl_need_approval, MIN( priv_upl_need_approval) AS priv_upl_need_approval FROM cm_usergroups WHERE group_id in (3) [bridge/udb_base.inc.php:357] (3.37 ms) [3] => SELECT group_name FROM cm_usergroups WHERE group_id= 3 [bridge/udb_base.inc.php:362] (5.95 ms) [4] => SELECT COUNT(*) FROM cm_categorymap WHERE group_id in (3) [bridge/udb_base.inc.php:375] (0.12 ms) [5] => SELECT aid FROM cm_albums WHERE moderator_group IN (3) [include/init.inc.php:271] (0.11 ms) [6] => SELECT lang_id FROM cm_languages WHERE enabled='YES' [include/init.inc.php:334] (0.24 ms) [7] => DELETE FROM cm_banned WHERE expiry < '2024-05-13 21:59:57' [include/init.inc.php:448] (0.71 ms) [8] => SELECT null FROM cm_banned WHERE ('3.141.202.30' LIKE ip_addr ) AND brute_force=0 LIMIT 1 [include/init.inc.php:464] (0.36 ms) [9] => SELECT aid FROM cm_albums WHERE (1 AND visibility != 0 AND visibility != 10000 AND visibility NOT IN (3)) [include/functions.inc.php:1110] (0.35 ms) [10] => SELECT category, title, aid, keyword, description, alb_password_hint FROM cm_albums WHERE aid = 2 [thumbnails.php:96] (0.34 ms) [11] => SELECT p.cid, p.name FROM cm_categories AS c, cm_categories AS p WHERE c.lft BETWEEN p.lft AND p.rgt AND c.cid = 13 ORDER BY p.lft [include/functions.inc.php:2943] (0.14 ms) [12] => SELECT null FROM cm_albums WHERE category < 10000 AND uploads='YES' AND (visibility = '0' OR visibility IN (3)) AND aid = '2' [include/themes.inc.php:2063] (0.4 ms) [13] => SELECT null FROM cm_albums WHERE category < 10000 AND uploads='YES' AND (visibility = '0' OR visibility IN (3)) AND aid = '2' [include/themes.inc.php:2063] (0.14 ms) [14] => SELECT title, keyword FROM cm_albums WHERE aid = 2 [include/functions.inc.php:2461] (0.35 ms) [15] => SELECT COUNT(*) FROM cm_pictures WHERE ((aid='2' AND aid NOT IN (12, 51) ) OR (keywords like '%27telp%' AND aid NOT IN (12, 51) )) AND approved='YES' [include/functions.inc.php:1408] (1.76 ms) [16] => SELECT r.pid, r.aid, filepath, filename, url_prefix, pwidth, pheight, filesize, ctime, r.title, r.keywords, r.votes, pic_rating, hits, caption, r.owner_id, user1, user2, user3, user4 FROM cm_pictures AS r WHERE ((aid = 2 AND aid NOT IN (12, 51) ) OR (keywords like '%27telp%' AND aid NOT IN (12, 51) ))AND approved='YES' ORDER BY position ASC, pid ASC LIMIT 24 ,12 [include/functions.inc.php:1439] (16.53 ms) [17] => SELECT extension, mime, content, player FROM cm_filetypes [include/functions.inc.php:5952] (0.19 ms) ) ========================== GET : ------------------ Array ( [album] => 2 [page] => 3 ) ========================== POST : ------------------ Array ( ) ========================== COOKIE : ------------------ Array ( ) ==========================
