Observatory Building On-Site!
The shed that will be The Walnut Ridge Observatory is now onsite! Given the crazy month May is turning into, it will be early June before I start building...
Sunspot 1476
Imaged this afternoon, sunspot 1476 has a 'beta-gamma' magnetic field, giving it a high potential for flares. It has already produced M-Class flares and is one of the largest groups seen in years. The forecast is 75% for M-Class flares in the next 24 hours, and 10% for powerful X-Class flares. The sport is not pointing directly at earth currently, but it could get very interesting when it does!

Composite of 2 shots
This is a composite of two differently processed versions of the same image, designed to show both prominences and surface detail. I need to work a little more on the technique, but it looks promising.

Crude, but effective!
This is the crude, but effective box I made for the camera. The lens has been removed and the circuit board mounted on foam in a little food container. The tube is the container for 35mm film cut and glued into place. It has the same diameter as a 1.25 inch eyepiece.

Video Imaging
I recently got hold of a .0001 lux color imager. It's an inexpensive board-based security cam based on the excellent Sony Super HAD CCD II (the board is about an inch square!). I'm looking forward to using it for 'live" views of deep sky objects. Initial tests show incredible low-light performance. I'll take the lens off tomorrow and put it in a case. Next step--hang it on the scope. Should be interesting!
The Observatory
The observatory will be a converted Arrow Highpoint 10' x 12' shed. The shed will be converted to a run-off. I am much indebted to those who have gone before me and converted this excellent building into an observatory. The plan involves making a wooden frame to top the walls, an identical frame on which to build the roof, and yet a third frame to stand on "legs" behind the building to roll the roof onto.
I will post images and movies as the building gets underway...wish me luck!
