Chinese Space Program - Long March - Shenzhou - Tiangong 2

We sometimes forget that it's not only the NASA, ESA or Roscosmos who are exploring space. The Chinese Space Program is running quit well. This month a powerfull Long March 2F/G Y11 space rocket launched the space craft Shenzhou-11 with two astronauts (taikonaut) to their space lab Tiangong-2. This is currently visible at night when it's crossing your area - see heavens-above for more information at your location.

DIY Making solar pictures using your DSLR on PST



How to make pictures using your DSLR on PST.  Using my D60 it's difficult to make prime focus pictures on the PST40. That's why I changed strategy and take pictures afocal using zoomlens 8-24mm with 24mm zooom. In order to bring the sun's surface into focus I need about 53mm to bridge. For that I need to install some spacers and finally the Nikon T-ring.
