  1. Hello Last time I setup my astrophotography equipment in order to capture a target during the night while I was sleeping. In the morning I woke up I saw to my frustration the telescope had hit the tripod legs. The route cause of this problem was that the system did not perform a meridian flip during the night. My setup consists of Skywatcher HEQ5 Synscan pro mount Vixen VC200L telescope SBIG ST2000XM ccd camera I did the following Launch ACP Observatory Control software Connect to CCD camera Connect to HEQ5 mount via ASCOM EQMOD Start session I would like to ask anybody who has experience with ACP + EQMOD what settings I need to configure in ACP and EQMOD in order to have meridian flip performed successfully and have a nice sleep during the night while the system takes astroimages on its own. Thank you Konstantinos
  2. Hello I hope you will enjoy this image of which was acquired this month from Korinthos city in Greece. It blends Ha and L-R-G-B data. I have paid special attention to reveal the star colors as well as the nebulosity itself. You can access the image with technical details under this link http://albireo.gr/astrogallery/nebulae/diffuse/2017.09.17/NGC7635_BUBBLE.html Enjoy and clear skies! Konstantinos www.albireo.gr
  3. Hello I hope you will enjoy this image of M52 Open Star Cluster which was acquired this month from a dark site in Greece. It blends L and R-G-B data. I have paid special attention to reveal the star colors. You can access the image with technical details under this link http://albireo.gr/astrogallery/stars/open_clusters/2017.08.18/M52.html Enjoy and clear skies!
  4. Hi Thank you all for the comments, I am glad you liked my photo. I have played a little bit with the Ring Nebula in Pixinsight in order to reduce its lightness and allow the inner stars to be more visible. Konstantinos
  5. I hope you will enjoy this image of M57 the Ring Nebula which was acquired last June from Korrinthos city in Greece. It blends L and R-G-B data. I have paid special attention to reveal the star colors and nebula color as well. There's a pretty spiral galaxy ΙC 1296 close to the Ring Nebula of magnitude 14.30. You can access the image with technical details under this link http://www.albireo.gr/astrogallery/nebulae/planetary/2017.06.24/M57_ring.html Enjoy and clear skies!
  6. Hello EveryBody! I would like to send my warmest greetings to all of you. I have a question regarding setup of the Vixen Sphinx mount during the summer season. I live in Greece where the time zone is UT+2 hours. During Summer, i set the hour setting in starbook 1 hour ahead (Daylight Saving Time), and the time zone to UT+3, as the manual says "starbook does not automatically compensate for daylight saving time". However, when i polar align using the Polar axis scope, and match the date to the time, i set the time back one hour, that is to say not taking account of daylight saving time. Is this correct? Or should i set the time in the Polar Axis Scope also to match summer time? The instructions of the Polar Axis Scope manual do not clarify this point, and the example refers to winter Time!
  7. M81 or Bode's galaxy is a large bright spiral galaxy located 11.8 million light-years from Earth in the constellation of Ursa Major. With an apparent magnitude of +6.9 it's easily visible with binoculars, a fine target for small telescope owners and a wonderful sight in larger scopes. The galaxy is a striking example of a grand design spiral; a galaxy that exhibits prominent near perfect and well defined spiral arms. Bode’s Galaxy was named after Johann Elert Bode, the German astronomer who discovered it on December 31, 1774.

  8. ok so you advise me to go ahead buying the 2" diagonal. Many thanks
  9. Hello I have the following flip mirror which accepts 1.25" eyepieces http://www.teleskop-express.de/shop/product_info.php/language/en/info/p242_Vixen-flip-mirror-for-2--systems---adapts-to-2x-T2---1-25-.html Now I am thinking to upgrade to this 2" dielectric diagonal https://www.firstlightoptics.com/diagonals/william-optics-2-dielectric-diagonal.html If I place a 1.25" eyepiece to this 2" dielectric diagonal will I have - wider field of view - better image quality - sharpher and brighter image ??? Thank you Konstantinos
  10. Hi I managed to correct the PAS alignment a lot but I realized is very difficult almost impossible to correct it perfectly. I think for optical observation of celestial objects you don't need to be perfect on this.
  11. Oh thank you so much, now it's all clear to me. I did not have this manual as this is a second hand mount I own.
  12. Hello Pete I release the altitude clamp and set the altitude of the mount to minimum value. The tripod is level. But when I look through the Polar Axis Scope I see only the sky. This happens because the PAS cannot be in horizontal position. To overcome this problem I have to adjust the tripod legs so that the mount is not level anymore. Have you also experienced this problem?
  13. Hi I have the Vixen Polar Axis Scope (vixen item # 2573) for the Vixen Sphinx mount. I have found the PAS is off by some minutes (refer to image pas.jpg) The procedure is basically to remove the counterweights and scope from the mount, rotate the RA axis so that the CW shaft points to the right horizon, point the PAS to a fixed spot on the landscape around 1 km distance, then rotate again the RA axis to make the CW shaft point to the left horizon and check it the PAS still pointing to the same spot in the landscape. Unfortunately the Vixen manual does not specify which bolt needs to be adjusted to correct the misalignment. There are possible 5 bolts as candidates. Which ones I need to adjust? Has anybody performed successfully this task and has some detailed instructions? Thank you Konstantinos
  14. Hello Thank you for the reply to this topic. Vixen recommends the following items to be used with Sphinx mount (1) Vixen #3599 12V mains adapter http://www.vixenoptics.com/Vixen-AC-Adapter-p/3599.htm Vixen AC Power Adapter Kit Includes Futaba Industries Model AC45-12 Power Supply made in Japan, with cord and male plug for Vixen products. Power Supply plugs into wall current to provide 12 volt DC current for use with the Sky Sensor 2000, and DD-1 controllers. This is not recommended for the SD-1 controller. For use with the SPHINX Starbook also order the P/N AM-AC-2537 Tip Adapter (described below). Power Input: 100 to 240 volt AC Output: 12 volt DC Ampere Rating: 3 Amp Power Cord Polarity: Center is Negative, Shield is Positive (2) Vixen #2537 tip adapter http://vixenamerica.com/Products/Default.asp?TopCatCode=AM&Fam_or_Cat=AM-AC&Short_Verbose=Accessory#AM-AC-2537 AC Adapter Sphinx Plug for use with AM-AC-3599 Converts tip of Vixen P/N AM-AC-3599 12 volt 3 amp AC adapter (described above) to work with SPHINX mounts. Will also work for any tip negative "M-plug". Plug Dimensions: outer diameter 5.5 mm, inner diameter 2.1mm) Plug Type: "M-plug" Cord Length: 67 inches / 171 cm Model # AM-AC-2537 (3) Vixen serial cable for starbook controller http://www.vixenoptics.com/product-p/25227.htm Reference: VX-25227 Manufacturer: Vixen Vixen serial cable for connecting Starbook controller onto Vixen equatorial mount (Vixen replacement part). All the above items cost around 200 Euros or 223$ to get them to my home location. I just wanted to ask what is the added value to buy these vixen items. e.g. I will have better GOTOs with the Sphinx mount? the mount will run more smoothly? The mount and starbook will be protected better from power fluctuations?... Another approach to all above is that I can save a lot of money if I buy budget equipment which also can do the job... Serial cable: https://www.amazon.com/StarTech-6-Feet-Straight-Through-Serial/dp/B00066HP2E/ref=sr_1_4?ie=UTF8&qid=1475526174&sr=8-4&keywords=db9+serial+cable Power unit made in China: https://www.alibaba.com/product-detail/50w-universal-charger-for-netebook-PSP_890034431.html Total Cost both around 10$ or I can buy this power unit, made in China, from Baader http://www.baader-planetarium.com/de/baader-otp-60w-outdoor-telescope-power-60w-mit-winkelstecker.html Total Cost with serial cable around 65$ Both Chinese power units offer plug with dimensions 5.5 mm x 2.1mm which is OK for the Sphinx mount. Could someone persuade me why to go with Vixen option? Thank you
  15. Hello everyone, I have recently acquired an old Vixen Sphinx SXW mount with star book controller. I have updated starbook to version 2.7 firmware. I need to buy the serial cable which connects star book to the mount. Also I need to buy the AC power adapter to power on the system. Will this serial cable and this ac power adapter fit my purposes? Other option is to buy straight from Vixen but these items I believe are highly overpriced. http://www.vixenoptics.com/product-p/25227.htm http://www.vixenoptics.com/Vixen-AC-Adapter-p/3599.htm Anybody who has this mount let me know. Thank you Konstantinos
