Distance from Earth is about 7,600 light-years.Aug 28, 2019 Messier 24 - "Small" Sagittarius Star Cloud487 viewsMessier 24 is an enormous cloud of stars lying in the Sagittarius arm of our galaxy, at a distance of about 10,000 light years from Earth. It is about 600 light years wide and occupies an area 90 arc minutes in apparent diameter. Among other objects, M24 contains the open cluster NGC 6603, which is at the center of this image. M24 is called the Small Sagittarius Star Cloud because there is another, larger star cloud south of it in Sagittarius, consisting of stars not obscured by the interstellar dust which blocks our view of the center of the galaxy. Aug 12, 2019 NGC 6520 and Barnard 86462 viewsNGC 6520 is an open cluster in the constellation Sagittarius, consisting of about 25 stars of magnitude 9-12. At its western edge (to the right in this image) lies the dark nebula Barnard 86 (B86).Aug 10, 2019 NGC 6522 - Globular Cluster in Sagittarius434 viewsPossibly the oldest star cluster in the Milky Way,[4] with an age of more than 12 billion years. Located in an area of the sky known as Baade's Window, named for the astronomer Walter Baade, who first recognized its signficance. Baade's Window is an area of the sky with relatively low amounts of interstellar dust along the line of sight from the Earth, allowing unobstructed observation of the center of our Milky Way galaxy.Aug 09, 2019 Messier 39 - Open Cluster in Cygnus368 viewsAn open cluster in the constellation Cygnus the Swan; distance 1010 light-years.Jun 24, 2019 M5 - Globular cluster in Serpens360 viewsA globular cluster - one of the largest known, with a radius of 200 light-years - in the constellation Serpens. Distance from Earth is about 24,500 light-years.Jun 20, 2019 NGC 457 - The Owl Cluster394 viewsAn open star cluster in the constellation Cassiopeia, about 7,900 light-years distance from our Solar System. The "eyes" are the magnitude 5 star Phi-1 Cassiopeiae and magnitude 7 Phi-2 Cassiopeiae.Jun 20, 2019 M45 - The Pleiades383 viewsA star cluster consisting of young, hot blue stars, about 130 light-years from Earth in the constellation Taurus. Only part of the cluster is shown here because it is too large to fit in the scope's field of view.Jun 19, 2019 Messier 13 - Hercules Globular Cluster366 views145 light-years in diameter, consisting of several hundred thousand stars, this is the most famous globular cluster in the Northern Hemisphere and is about 22,000 miles from Earth.Jun 19, 2019 NGC 869 and 884 - The Double Cluster in Perseus350 viewsOver 7500 light-years away, these twin open clusters each contain over 300 blue-white supergiant stars; they are about 13 million years old.May 12, 2019     22 files on 2 page(s) 1 2 Debug Info  Debug Output: show / hide Select All USER: ------------------ Array ( [ID] => a5426075761634b141da167eb52e4a44 [am] => 1 ) ========================== 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] (0.56 ms) [1] => SELECT * FROM cm_plugins ORDER BY priority [include/plugin_api.inc.php:48] (0.31 ms) [2] => SELECT user_id, time FROM `i5493328_cm1`.cm_sessions WHERE session_id = '1ae0f0300c3cd127887043ce09b2d4d3' [bridge/coppermine.inc.php:241] (0.18 ms) [3] => 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:350] (0.21 ms) [4] => SELECT group_name FROM cm_usergroups WHERE group_id= 3 [bridge/udb_base.inc.php:362] (0.16 ms) [5] => SELECT COUNT(*) FROM cm_categorymap WHERE group_id in (3) [bridge/udb_base.inc.php:375] (0.15 ms) [6] => SELECT aid FROM cm_albums WHERE moderator_group IN (3) [include/init.inc.php:271] (0.12 ms) [7] => SELECT lang_id FROM cm_languages WHERE enabled='YES' [include/init.inc.php:334] (0.16 ms) [8] => DELETE FROM cm_banned WHERE expiry < '2025-12-01 03:55:40' [include/init.inc.php:448] (0.74 ms) [9] => SELECT null FROM cm_banned WHERE ('216.73.216.55' LIKE ip_addr OR '' LIKE ip_addr ) AND brute_force=0 LIMIT 1 [include/init.inc.php:464] (0.86 ms) [10] => SELECT aid FROM cm_albums WHERE (1 AND visibility != 0 AND visibility != 10000 AND visibility NOT IN (3)) [include/functions.inc.php:1110] (0.66 ms) [11] => SELECT category, title, aid, keyword, description, alb_password_hint FROM cm_albums WHERE aid = 11 [thumbnails.php:136] (0.92 ms) [12] => 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:2940] (0.15 ms) [13] => SELECT COUNT(*) FROM cm_pictures AS r INNER JOIN cm_albums AS a ON a.aid = r.aid WHERE (r.aid = 11) AND (1 OR keywords like '%27telp%') AND r.aid NOT IN (12, 51) AND approved = 'YES' [include/functions.inc.php:1614] (2.27 ms) [14] => 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 INNER JOIN cm_albums AS a ON a.aid = r.aid WHERE (r.aid = 11) AND (1 OR keywords like '%27telp%') AND r.aid NOT IN (12, 51) AND approved = 'YES' ORDER BY ctime ASC, pid ASC LIMIT 0 ,10 [include/functions.inc.php:1630] (2.59 ms) [15] => SELECT extension, mime, content, player FROM cm_filetypes [include/functions.inc.php:5952] (0.3 ms) ) ========================== GET : ------------------ Array ( [album] => lastup [cat] => -11 [page] => 2 ) ========================== POST : ------------------ Array ( ) ========================== COOKIE : ------------------ Array ( [cpg16x_data] => YToyOntzOjI6IklEIjtzOjMyOiJhNTQyNjA3NTc2MTYzNGIxNDFkYTE2N2ViNTJlNGE0NCI7czoyOiJhbSI7aToxO30= [a520716e4e1a802c3b699f97dd5ac36c] => 9e3bc8888b98656f88ad8f298ae29eea ) ==========================
