  1. From the album: SPAG Monfrague Remote Observatory

    The galaxy features an outer ring swirling around an inner ring with a subtle bar structure in the center. A bar is an elongated distribution of stars and gas in the center of a spiral galaxy. The central regions of the galaxy are predominately populated by young stars, with the galactic fringes also featuring areas of active star formation. Central bars are found in around two thirds of spiral galaxies. NGC 3344’s is clearly visible here, although it is not as dramatic as in some galaxies. The high density of stars in galaxies’ central regions gives them enough gravitational influence to affect the movement of other stars in their galaxy. However, NGC 3344’s outer stars are moving in an unusual manner, although the presence of the bar cannot entirely account for this, leaving astronomers puzzled. It is possible that in its past NGC 3344 passed close by another galaxy and acquired stars from it, but more research is needed to state this with confidence. Credit: ESA/Hubble & NASA
  2. I use Sequence here as a basis for my remote-robotic system since some months ago. It works perfectly as a standalone system ( Sequence+Autoslew+maximDL). That´s all I need . . I can image all night long without noticeable problems.It´s working for me. Of course it could be improved with some other tips... but I guess ASA & Mr. Keller take note of users wish list for a next version ( or I hope so...) . My imaging skill has been improved 100% . I have also installed the Secure System "TALON6" in order to avoid any problems and have complete safety for my remote observatory ( weather events, electricity fails, lost of PC communication,hangs of Windows,timeout, lost of internet connection..etc....,etc ,etc. It try to park the mount) and ALWAYS and close roll-roof systems or even any Dome system ( as it works perfectly with Sequence (ASCOM compliant) . It´s a total universal "panic" system . With Sequence and TALOn6 , I go to bed an can sleep with TOTAL tranquility.I have installed it here since past summer. For interested guys (English) here is the link: . BTW: I don´t have ANY commercial interest . I am only a user ¡.. http://observatoriosspag.es/index.php/en/component/content/article/84-o-a-r-spag/361-talon6-2.html and this: http://observatoriosspag.es/images/R.O.R%20Talon6/IP_Switch_user_manual.pdf Just my two cents CS Antonio

    Barnard 3

    Thanks Mark ¡..

    Barnard 3

    This is Barnard 3, a dusty, gassy region of the galaxy about a thousand light years away where young stars are lighting up their neighborhood.Complex molecules similar to soot, called polycyclic aromatic hydrocarbons or PAHs. . So what’s going on here? Near the center is a F2 white-yellow star ( HD 278942) which is brighter and hotter than our Sun, and is flooding the surrounding material with ultraviolet light and a fast wind of subatomic particles (like the Sun’s solar wind, but a whole lot stronger and with a much, much farther reach). This has carved out a gigantic cavity in that stuff, creating a bubble about 25 light years in diameter — that’s huge: 250,000,000,000,000 kilometers across, more than 10,000 times the size of our solar system! The UV from the star is making the gas glow.In optical light (this object is a mess , with gas emitting light, reflecting light, and dust absorbing it. When gas is lit up this way around a star, it’s called a Strömgren sphere, after the astronomer Bengt Strömgren who did the first theoretical work on them. An infrared image of the area can be seen here:http://wise.ssl.berkeley.edu/gallery_Barnard3.html Credit: (Phil Plait, Discover Magazine, December 2011) Link to more info and high resolution image: http://afesan.es/Deepspace/slides/Barnard%203%20%28Perseus%29.html CS ¡ Antonio

    Very difficult target . Nice procesing, Ron ¡

  9. Great¡¡¡. Agree with George... Color is top ¡¡
  10. Nice internal structures detail and colour, Ron ¡
  11. DG 181, DG 182 (Dorschner+Gurtler catalogue) are two tiny blue reflection nebulas located between the LDN´s 1175 and 1184, into the cloud TGU640 of Cepheus constellation..Rarely imaged (or never imaged ? ) the area also contains IR objects such as IRAS 22148+6033,IRAS 22151+6040,IRAS 22158+6041 ans X-Ray objects as 1RXS J221635.3+604813 . The whole area is inmersed into a mix of dust and reflections , making it a difficult task for astrophotographers. A lot of hours were invested in order to present it with some detail and colour. Many thanks to Sakib Rasool for pointing these targets. Hi.resolution: http://afesan.es/Deepspace/slides/DG%20181%2CDG%20182%2C%20LDN%201175%2CLDN%201184%20%28Cepheus%29.html

  14. You will can value also how the pass of Milky Way over zenith also affects SQM readings :-)... Mine is working here from past couple of years ( LE version) ...and works OK. As you stated.. Cloudwatcher and SQM instruments have different purposes... But SQM helps me to establish if my images can be of quality and to determine point when I usually begin to image : I never image until SQM readings are over 21.1 .. Evidentey this is a local measure imposed to myself... You will enjoy it and will find your own utilities.. Antonio
  15. Fantastic one with a DSLR...¡.. Really did you remove the bayer Matrix ?? .. Then it´s a big improvement for narrowband, indeed...¡ Congratulations¡ Antonio
  16. Hi Pavell. Fantastic image... A gem ¡¡ .. Just a little appreciation of a problem into the upper-center-left side of sensor with stars out of focus with respect to the image. Spikes and star sizes are different--- so it seems to me there is a little problem of distances in the optical train...?.. Colour, procesing and details. overall...are great ¡- Congrats¡ Antonio
  17. Welll.. I just image with MLPT and Sequencer all over the night in a remote-robotic observatory ....without any problems at all. I always use a full model of the sky and MLPT.. , but this is just a personal taste.. I like to have always a previous model for the whole Sky. My subframes are always into the range of 10-15 minutes LRGB and 20-30 minutes narrowband. No problems at all. Perfect round stars. If you experience problems I will re-check the hardware area ( balance, counterweights, motors parameters) and , of course... mirror movements or focuser sights... Most of my initial problems came for movements of primary mirror (in case of a reflector).... Just my two cents... CS ¡ Antonio
