Crescent Nebula

The Crescent Nebula (NGC 6888) is a cosmic bubble about 25 light-years across in the constellation Cygnus, blown by winds from its central, bright, massive star. The nebula’s central star is classified as a Wolf-Rayet star (WR 136). The star is shedding its outer envelope in a strong stellar wind, ejecting the equivalent of the Sun’s mass every 10,000 years. The nebula is 5000 light years from us.

I captured the image last weekend with a Megrez 120mm, Canon 60Da camera, unfortunately exposure was limited to 120 minutes in all, the image was processed in PixInsight. Mike

Dominion Radio Astrophysical Observatory in the Okanagan

Join us for what will be a fascinating talk

Our sun is still an interesting place to view!

I took this image through the clubs new Quark Hydrogen Alpha (Ha) eyepiece last Friday mid afternoon (14/7/18), seeing was quite good. The combination of camera/eyepiece/telescope results in a small field of view, but one where the details of the solar chromosphere are revealed very nicely. The image was taken in monochrome and coloured to match the Ha colour..We are looking at an area where bundles of magnetic fields lines are concentrated.

We will have the eyepiece, and other solar viewing equipment in use at the Gibsons Art Gallery next Saturday for our meet and greet with Erwin. Come by and take a look at his images and the sun!

 

New focuser installed today

The new “Feather Touch” focuser that we have been after for some time was finally installed today. The focuser will provide a more precise control over the fine focusing of the telescope and will comfortably handle heavy eyepieces or even cameras. The focuser was purchased with part of the grant that we received from Rotary – thank you!.
