Home > Astronomical Images > Deep Sky Last additions - Deep Sky Markarian's Chain253 viewsPart of Markarian's Chain, a group of galaxies in the Virgo Cluster. Visible in the photo are NGCs 4477, 4473, 4461, 4458, 4438 and 4435. Not visible are M84 and M86, which are out of the frame to the right - my telescope's field of view is not big enough to capture them all.Jun 23, 2020 M95 and M96219 viewsTwo Spiral Galaxies in Leo, captured in the same frame Mar 22, 2020 IC 5067 - The Pelican Nebula254 viewsAn emission nebula (H-II region) in the constellation Cygnus, associated with the North American Nebula (NGC 7000), but visually separated from it by a dark dust cloud. Supposedly has the shape of a pelican, though not very much in this image. Sep 10, 2019 NGC 7009 - The Saturn Nebula276 viewsA planetary nebula in the constellation Aquarius, at a distance of about 5000 light-years, with a superficial resemblance to the planet Saturn. This image does not do it justice, because a much larger telescope is required to resolve the complex internal structure of the nebula.Sep 01, 2019 NGC 7789 - Open Cluster in Cassiopeia223 viewsDiscovered by Caroline Herschel in 1783 and nicknamed "Caroline's Rose" because of its supposed floral appearance. Distance from Earth is about 7,600 light-years.Aug 28, 2019 Messier 24 - "Small" Sagittarius Star Cloud311 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 86248 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 Sagittarius232 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 Tulip Nebula - Sh2-101225 viewsAn emission nebula about 6,000 light-years away in the constellation Cygnus. The shape vaguely resembles the outline of a tulip.Aug 04, 2019 NGC 4725329 viewsA one-armed spiral galaxy in the constellation Coma Berenices, about 41 million light-years from Earth. This is a Seyfert galaxy, meaning that it has a very active nucleus; it is also a barred spiral and has a prominent ring structure. It is interacting with NGC 4747 in the upper left corner of the frame, resulting in severe distortion of both galaxies and producing the spectacular tidal tails seen with NGC 4747. The smaller spiral galaxy to the right of NGC 4725 is NGC 4712. Jul 20, 2019 M42 - The Great Nebula in Orion240 viewsAnother take on the Great Orion Nebula, incorporating hydrogen-alpha data.Jun 24, 2019 Messier 39 - Open Cluster in Cygnus205 viewsAn open cluster in the constellation Cygnus the Swan; distance 1010 light-years.Jun 24, 2019 161 files on 14 page(s) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Debug Info  Debug Output: show / hide Select All USER: ------------------ Array ( [ID] => cb2f316a79113706e5c9dcf0c2c7c0e5 [am] => 1 [liv] => Array ( [0] => 186 [1] => 1060 [2] => 1089 [3] => 569 [4] => 1759 ) ) ========================== 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] (0.4 ms) [1] => SELECT * FROM cm_plugins ORDER BY priority [include/plugin_api.inc.php:48] (0.25 ms) [2] => SELECT user_id, time FROM `i5493328_cm1`.cm_sessions WHERE session_id = 'd01488838105575d1c4598c80c8d2279' [bridge/coppermine.inc.php:241] (0.21 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] (0.53 ms) [4] => SELECT group_name FROM cm_usergroups WHERE group_id= 3 [bridge/udb_base.inc.php:362] (0.18 ms) [5] => SELECT COUNT(*) FROM cm_categorymap WHERE group_id in (3) [bridge/udb_base.inc.php:375] (0.22 ms) [6] => SELECT aid FROM cm_albums WHERE moderator_group IN (3) [include/init.inc.php:271] (0.14 ms) [7] => SELECT lang_id FROM cm_languages WHERE enabled='YES' [include/init.inc.php:334] (0.22 ms) [8] => DELETE FROM cm_banned WHERE expiry < '2025-10-12 06:49:11' [include/init.inc.php:448] (0.65 ms) [9] => SELECT null FROM cm_banned WHERE ('216.73.216.211' LIKE ip_addr OR '' LIKE ip_addr ) AND brute_force=0 LIMIT 1 [include/init.inc.php:464] (2.12 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] (0.59 ms) [11] => SELECT name FROM cm_categories WHERE cid = 13 [thumbnails.php:157] (2.31 ms) [12] => SELECT rgt, lft, depth FROM cm_categories WHERE cid = 13 LIMIT 1 [include/functions.inc.php:44] (0.43 ms) [13] => SELECT cid FROM cm_categories WHERE lft BETWEEN 6 AND 7 [include/functions.inc.php:49] (0.21 ms) [14] => SELECT keyword FROM cm_albums WHERE category IN (13) [include/functions.inc.php:57] (0.19 ms) [15] => 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] (0.19 ms) [16] => SELECT COUNT(*) FROM cm_pictures AS r INNER JOIN cm_albums AS a ON a.aid = r.aid INNER JOIN cm_categories AS c2 ON c2.cid = category WHERE (c2.lft BETWEEN 6 AND 7) AND (1 OR keywords like '%27telp%' OR keywords like '%27telp%' OR keywords like '%27telp%') AND r.aid NOT IN (12, 51) AND approved = 'YES' [include/functions.inc.php:1614] (8.83 ms) [17] => 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 INNER JOIN cm_categories AS c2 ON c2.cid = category WHERE (c2.lft BETWEEN 6 AND 7) AND (1 OR keywords like '%27telp%' OR keywords like '%27telp%' OR keywords like '%27telp%') AND r.aid NOT IN (12, 51) AND approved = 'YES' ORDER BY ctime ASC, pid ASC LIMIT 29 ,12 [include/functions.inc.php:1630] (70.81 ms) [18] => SELECT extension, mime, content, player FROM cm_filetypes [include/functions.inc.php:5952] (4.57 ms) ) ========================== GET : ------------------ Array ( [album] => lastup [cat] => 13 [page] => 11 ) ========================== POST : ------------------ Array ( ) ========================== COOKIE : ------------------ Array ( [cpg16x_data] => YTozOntzOjI6IklEIjtzOjMyOiJjYjJmMzE2YTc5MTEzNzA2ZTVjOWRjZjBjMmM3YzBlNSI7czoyOiJhbSI7aToxO3M6MzoibGl2IjthOjU6e2k6MDtzOjM6IjE4NiI7aToxO3M6NDoiMTA2MCI7aToyO3M6NDoiMTA4OSI7aTozO3M6MzoiNTY5IjtpOjQ7czo0OiIxNzU5Ijt9fQ== [a520716e4e1a802c3b699f97dd5ac36c] => 27d80fa7947506e1b157874edf018c3f ) ==========================
