  1. Hello, Cygnus is amazing source of interesting objects, so decided to spend a third summer in row on projects in this constellation. Looking on widefield images selected few regions and digging into the catalogs narrowed the starting point for this image to be the NGC 6914. The Ha version of the image explains why decided to name it Yin-Yang :) Total 8h 44min - WO 80FD, QHY22, Ha+RGB, APT, PHD2, PI, PS. It is also the first light of the my new mount CEM60. Kind of hard first light because am facing some problems, but am sure that will fix them very soon with the iOptron support :) In fact identifying the objects in the image is a real hunt The left blue nebula near the center is NGC 6914, the one in right is vdB132, more right and bit up is vdB131. All these blue nebulae are surrounded from the LDNs 899 (left part) 897 (right till the frame border). The part of the emission nebula bellow the LDNs to right are LBN 218 and 273. The emission in the left and upper part of the frame should be LBN 292, but is possible some parts of it to be cataloged as separate numbers... Let add one more catalog in the mix The small comma like sign under vdB131 is the bipolar planetary nebula Parsamian 22. The whole region is 6000 l.y. away and is considered that the emission red part is lit by the ultraviolet light of very hot stars part of the Cygnus OB2 association. These stars are ionizing the atomic hydrogen gas.
  2. Many thanks! We will add it in 3.80 or 3.90, just have to finally address some given promises Like native ZWO support
  3. APT 3.70 is here! It comes with access to completely new technologies for controlling astro gear – INDIGO / INDI, possibility to use RaspberryPi computers and the commercial products based on them - ZWO ASIAir, QHYCCD StarMaster, StellarMate. Integrated is the Lacerta’s FBC- Flat Box Controller. Added is support for GPS devices and smartphones. To finish the summary will mention the Keys Thingy – another way to enter data without keyboard in the dark. The usual list of the changes is available here: http://www.astrophotography.app/news
  4. APT DC is updated to 1.8. Fixes the calculations in the Daylight Saving period.
  5. Many thanks Barry! Next winter will bet back on it. It is getting too low now
  6. I mean that without bulb control the longest exposure that APT can possibly control is just 30s
  7. Hi John, Exactly, there is no much sense to implement support for camera that can't make exposure longer than 30s... I had talks with a manager in Sony, but didn't succeed to convince them in the importance about that. In 2017 managed to find a possible workaround, but star eater problem was still there... We are working on INDIGO integration in APT, so is possible to get kind of Sony support via Raspberry PI later this year. APT 3.70 will control CCD/CMOS and the related wheel, focuser and mount via INDIGO. Then have to take care for some highly wanted features, so maybe in the autumn will try to add DSLR support via INDIGO...
  8. Hi John, We have plans to add Sonny support for many years. There were two main showstopper defined by Sony itself - star eater and lack of bulb exposure control... Every year we are checking once or twice if there is solution for the second problem. Our schedule is full for some months ahead but will not skip this check later in the year
  9. Total: 5h, WO 80FD @ f/5.9, QHY22, Astrodon HII 3nm, APT, PHD2, PI, PS The Spider and the Fly "pair" are visually close neighbors of the famous Auriga nebulae "Faming Star" (IC405) and "Tadpoles" (IC410). The smaller object in the upper part of the frame is NGC 1913 (Sh2-237) called the Fly. It is considered as smaller version of the Orion nebula – contains a young cluster, it’s Trapezium, has an emission and reflection parts. The brighter object is IC417 (Sh2-234) which should be the spider who waits for prey, laying in the faint web (personally I see more obvious figure in the lower left angle). IC417 also hosts a young cluster (Stock 8) and the two small clouds above the brightest star hide stellar nurseries. The emission part dominates the region, however with the appropriate imaging time is possible show also the reflections from the hot and massive blue stars. A near infra-red study with Spitzer Telescope shows that the bright wave from the Spider towards the Fly hides packs of young stars that maybe form that interesting shape from the clouds located between them and us. The distances to the objects in the region show curious facts. The two nebulae are ~500 ly away from each other. Respectively ~7 500 and ~7 000 ly from Earth for IC417 and NGC1931. It looks that there is no direct connection in this “pair” as well as with the neighbors - IC405 ~1 500 ly, IC410 ~12 000 ly away from Earth. The whole complex looks very close just visually, but is spread out on more than 10 000 ly in the Orion-Cygnus arm of Milky Way. Definitely both the Spider and the Fly are interesting objects alone and in pair, so most likely next winter will get back to them for more data.
  10. Many thanks for the feedback and the good news!
  11. Interesting Do you have "PHD2" selected in Gear Tab->Guide? Maybe you were lucky the star loss to happen when dithering move was completed... Anyway it is better to have the latest version installed
  12. Hi Michael, Wish you clear skies for the eclipse!
  13. If you are using dithering and PHD2, please upgrade to APT 3.63 in order to avoid the possibility for imaging hanging in case of temporary guide star loss! The update is needed even if you are using 3.57… We are using the release to include some improvement and fixes in AMF (Automated Median Flip), DARV fix for Nikon cameras and also the “automatic settings restore after crash” feature we just finished. The Moon will soon start getting smaller so update your APT and be ready for the next imaging session! https://www.astrophotography.app/downloads
  14. Hi Han, For the next official version will implement native support for ASTAP
  15. Hi Roland, I have thought about that, but it will make the APT download size almost 1GB and not all APT users are using PointCarft (or at least in the beginning ). It is other topic if PlaneWave will agree to do it.
