Solar Row + Cal K

Solar Scope Row and Calcium K!

Observe The Sun Safely - Never look at the Sun without a proper filter! 

 Solar Programs are held 1st Sunday of every Month 2:00-4:00 PM at Houge Park  weather permitting

Lots of Solar Scopes lined up today at Houge Park and with superb variety! We were treated to live screen captures of the sun in Calcium K band by Carl Reisinger. And Robert Duvall (baseball cap below pic) brought his Standard Filtered Dob stacked with an H-Alpha finder (yuk yuk). High resolution shots of the above are below so read on.

Next to Robert in the above pic is a bloke visiting from Malaysia. He spent the whole afternoon looking through this row of high tech equipment and was gobsmacked. In his home country, he has two telescopes and is well known for his efforts to share the wonders of the sky.

Two fine solar scopes: Coronado PST and JMI Binocular.

Below is today's sun at a glance courtesy of Robert Duvall. 2 Large Sunspot groups and two smaller active regions resulted in a sunspot count of 60. The Largest group had a fantastic Penumbra network surrounding the inner umbra. Paul's 8 inch SCT which he set up later showed this network beautifully as did Michael Swartz's 100mm Stellarvue with green continuum filter and Binocular. And here is Robert's images through his equipment. Make sure you see the large rendition by clicking on image.

And below is a pic of Carl Reisinger and Calcium K Setup. The image to the left is a totally raw image. Note the extensive and hot plage (white) network that this filter easily picks up. This plage is actually a better indicator of how active the sun is and can point to areas where sunspots may form. Click the Pic!

Below pic of Michael Swartz at his cool duel refactor setup. Both refractors have binoviewers making this setup one of the best observing stations on the row. The binoculars radically improve the noted resolution (as you are using both eyes). The continuum filtered view compares well with Paul's filtered 8-inch SCT while Michael's bino H-Alpha yields 3D like views. Both images seen through this duel setup are crazy beautiful.

Below is a pic of Bill O'Niel looking through Michael's setup. Bill brought his 5-inch SCT which is a very portable scope that gives very satisfying details of larger spots like we had today. Aperture rules when viewing sunspots and so, unless you have a bino'ed refactor, you will want at least a 5-inch scope to see penumbra network detail.
