The 125399 Visual 2.75" to 2" adapter is an optional accessory that is designed to space a 2" diagonal for visual use.
We started the project on and in may 2011 we ended it. There are only about 300 Wolf-Rayet stars known in our galaxy. This nebula gets its name from the fact that the main cloud is tri-sected by a dark nebula into three main sections.
Imageprocessing has been done with CCDStack v2 and Photoshop CS5. The bubble is approximately 6 light-years in diameter.

BD 602522 is a “Wolf-Rayet” star, a star in the end stages of its life which emits fierce stellar winds (charged particles streaming from its surface) rapidly depleting its mass until it finally dies in a supernova.
The focus tube runs on 5 bearings and is driven by a leadscrew so there is no chance of slipping.
Focus may be automated through a computer using Plane Wave's EFA Kit add-on. Image 1 Image 2Three fans blow out of the optical tube pulling air though the telescope and by the primary mirror.
