As Greek mythology told us: ....: "So it is that Perseus found the cave of the three Graeae women. The Graeae shared a single eye for all three of them which they constantly fought over..:". Perseus took it. vdB 18 seems to be a deep , fix eye ,looking impassive.... Sidney van den Bergh's comprehensive catalog of galactic reflection nebulae, published in 1966, contains 158 entries representing nebulosity around BD- and CD-type stars north of -33d and as identified in both red and blue Palomar Sky Survey prints. These entries represent diffuse reflection nebulae which are illuminated by one or more background stars and, in other instances, by the integrated light of the Milky Way.vdB 18 is catalogued as Type II (star outside the nebulosity) and Surface brightness F (Faint). This nebula is rarely imaged (I can´t find any image.. just some widefield ones)..and never detailed.The central star is V496 Per -- Variable Star of alpha2 CVn type. The nebula is surrounded by dust ... dust everywhere from the Lynds Dark nebula LDN 1434 and Lynd´s Bright nebulas LBN 720 and 721.A dozen of galaxies emerge between dust.vdB 18 seems to be an open eye The eye of Perseus.

Many thanks Matts and Markus. It was a nice surprise when processing the image to see some minor structures and patches I never seem before. Thanks for looking and comments. Best regards, Clear skies. Antonio

You are very kind Waldemar. Thanks¡¡

Maybe this could be the first amateur image of this object (vdB 47).. a curious orange one..¡¡ A detailed image can be seen in the link at the end of this message.. There are not clear references into the Sharpless catalog: http://galaxymap.org/cat/view/sharpless/243 and just some minimal explanations..but I can´t locate any clear image of it. This image was taken unguided with the new Sequence BETA version along all November month . A fantastic soft.¡ vdB 47 (SH2-243 ) (Taurus) * November 2013 * ASA N12 astrograph (f/3,6,1078mm) * ASA DDM85 mount * FLI ML8300 at -25ºC * LRGB Optec filter set * L:690m R:170m G:150m B:170m * vdB 47 is a reflection nebula associated with an emission visible in the constellation of Taurus. It is a cloud of gas that surrounds the star HD37387, an orange supergiant of spectral class K1Ib,placed at a distance of 6500 light years, at the inner end of the Perseus arm. The nebula has a distinctly orange colour due to the radiation of this star ,having an effective temperature of 4500 kelvin.This cloud may be associated with the region of star formation , which also belongs to the maser DG68 and the IRAS source 05363+2317,together with some sources o radio waves ( Reference: Wikipedia).

FIne details, Gerhard...¡Excellent processing. Just a little bit noisy to my taste.. but colours and details are splendid. Antonio

Very nice one¡

Many thanks for your kind comments, Gerhard ... Actually I´m trying to search never imaged before targets or,at least, uncommon ones.. Thanks for lopking at ¡ Best regards, Antonio

Large image can be seen here: http://afesan.es/Deepspace/slides/NGC%201528%2C%20SH2-209%20LRGB%20%28Perseus%29.html SH2 - 209 is located in one of the outer arms , on the edge of our galaxy, about 16,000 light years ... overshadow by a dust cloud. As any other HII region,it is show when the ultraviolet radiation from surrounding stars ,ionize gas all around., thereby causing the brightness of the light spectrum visible.The surrounding dust is heated by radiation and this allows it to be seen also into infrared spectrum..These regions are characterized by being nest of new stars.. This link can be seen and SH2 -209 SH2 -206 ( aka NGC 1491 ) portrayed by the WISE telescope in the infrared . SH2 -209 is located to the left of the image. http://wise.ssl.berkeley.edu/gallery_ngc1491.html Discovered by William Herschel in 1790 , NGC 1528 is an open cluster (Archinal Brent and Steven Hynes catalog with about 165 stars), with the brightest set in the order of magnitude 8.7 .. It stretches over about 13 year light into space..Ithas an estimated age of about 300-370 million years ago ( A modest age , compared with the cluster NGC 6791 in Lyra , which are attributed to between 7 and 8 billion years) It is approximately at 1530 years light ... thus ,in the picture,althought both targets seeems to be into same plane ... SH2 -209 is about 14.5 thousand years more distant light.. A trifle :-) The Russian astronomer A. V. Lotkin , has cataloged NGC1528 and NGC1545 ( another small cluster located less than a degree and a half , but not in this image field ) as a possible binary cluster probably captured by tidal.." Both clusters have similar galactic coordinates , ages , distances and mediam radial velocities If they are really a couple ...it could be the second double cluster in Perseus (besides the well-known " Double Cluster " NGC869 and NGC884 ) .

Close to Pacman is an ignored little group of blue reflection nebulas inmersed into a dust cloud, IRAS targets and even submillimetric radio fonts.Main reflection nebula is DG6. Almost 24 hours were invested due for this weak target and present it decently.I attached also a prehistoric paint of a horse from Altamira´s Cave (Spain) as it´s very similar to the dust nebula. Both images are messengers from the past:one coming from men hand (18000 years B.C.) and the other by Universe light millions of years ago.

A friend of mine, Antonio Perez (ASA user also) wrote this script for use with AAGCloudwatcher as a script in order to park my DDM85 when skies are going cloudy :-). I hope his can be useful to you , Lukas.. BR Antonio ' Create telescope object Set Scope = CreateObject("AstroOptikServer.Telescope") ' Connect to the object scope.Connected = True If Not scope.connected Then wscript.echo "Failed to connect the scope." Quit End If Scope.Park scope.connected = False If scope.connected Then wscript.echo "Failed to disconnect the scope" Quit End If

This is an rare imaged target at cepheus. A Lynd´s dark nebula surrounded with a "hair flow" like a blowing wind all around. I had to invest almost 10 hours into the L filter in order to battle against light pollutions..as although my remote observatory is at a dark site ( 21.3-21.7 skies)..north is damaged with some light pollution from a minor village.. larger image can be seen here : http://afesan.es/Deepspace/slides/LDN%201221%20LRGB%20%28Cepheus%29.html Regards. Antonio

I´m with you Gerhard¡.. Revision is more into my taste. First one is excesiively green side to my eyes. But colours is just a question of persons :-9 (fortunately¡). Anyway... you are going into narrowband with all honours¡, Great image¡.. Maybe I must try narrowband in a future... but I feel shy and alzy with this :-) Wonderful sight, Gerald . BR Antonio

COngratulations. Yes Nerpio is a ver good place with dark skies. Fortuantely ..we maintain some minor dark places all over Spain. I´m sited in another great dak place at Southwest of Spain.. .near National Park of Monfrague (Caceres).. with most nights into the 21.3-21.7 darkness range .... Unfortunately pollution pression is growing all over the country. I can see it everyday due to my travel opportunities for all over the country. Dark sites are like extinct danger species... A treasure to keep. Enjoy Nerpio, Monfrague, Ager,..These are the last places ...I´m afraid :-( The image is an spectacle itself¡. SImply a little masterpiece. BR Antonio

A classic (lovely) image ¡.. Just 1h 20m?, What sane envy ¡¡¡ Greta results and fantastic processing skill, Gerhard. BR Antonio

I like the 3D sensation a lot. Congratulations for this nice result. Also colours are very different compared with the "traditional" Hubble or CFHT palettes.. Nice , nice job ¡ BR Antonio

Nice one with just over 2 hours¡

Any estimated date out for the new Sequence ?? BR Antonio

Deep results with a DSLR Thomas¡. Good color balance and nice procesing ¡ Dust everywhere and contained noise. Good job¡ Antonio

Pure Ha images always transmit impactant results. I never get tired of see those ones. Very nice ¡.. soft..pure...,details.. Thanks for showing Antonio
