NGC6826 - The Blinking Nebula.
This on Wiki:
NGC6826 is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "blinking planetary", although many other nebulae exhibit such "blinking". When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding nebula. However, it can be viewed well using averted vision, which causes it to "blink" in and out of view as the observer's eye wanders. A distinctive feature of this nebula are the two bright patches on either side, which are known as Fast Low-Ionization Emission Regions, or FLIERS. They appear to be relatively young, moving outwards at supersonic speeds.

Looks like I'm going to have to have another go at my collimation. Very happy with this even so, as it's the first serious imaging I've done for sooo long! A lot more data is required to bring out the detail in the nebula.
This video is intended to be for someone who is thinking of buying their first scope but isn't sure which one is best. I would love it to be a good jumping off point for discussion and I hope some wise heads will wade in and answer questions and offer alternative opinions. Thx to astrostace and helena's astro and deddy dayag for contributing. I fear I'm going to have my head down making my next video as I'm currently astrobiscuiting full time (or at least till my loan runs out!). So all help much appreciated. 😉
I'm trying to get a photo of Jupiter and Saturn with my Nikon D3000 DSLR but I can't get anything clear. I attached the kind of photos I'm getting with my camera. They end up being too bright and no distinguishable features show up. Is it even possible for my Nikon to get photos of planetary objects like Saturn and Jupiter?
Friends, I am back with a tutorial video on how to modify your Sky Watcher HEQ5-PRO mount or its American twin, the Orion Sirius EQ-G into a belt driven mount.
The benefits of converting to a belt drive is that you don't have to worry about Backlash. The procedure took me about an hour to complete.

By stepping beyond
I've had 3 new mounts since after Xmas last year and it has been a real pita trying to get the first to mounts to operate correctly with my Sgp Software . March rolled in and I had lost too much time trying to get the 1st 2 mounts to do the job . I dipped back in the kitty and got an AVX straight out of the box took me to galaxies FAR FAR AWAY, WOOHOO! I've been trying to process the galaxy for a mount and match it with my archived data and finally I'm getting somewhere.
