On August 28 solar observer Jim Lafferty trained his LS100THa/B3400 scope towards the sun.  Though this was a short session for Lafferty due to the 112 degree heat he still managed to capture a stunning image of a massive prominence.  With images like this Lafferty is truly becoming a world class solar imager and I recommend keeping an eye on all his work on Cloudy Nights!

The sun continues to put on quite a show today with its array of active regions.  The image below shows AR1226 and 1227 with their collection of dancing filaments.   Currently there are six active regions visible on the sun, providing a lot of different things to view and image!  It will be exciting to see what unfolds over the next few days as some of these regions have been producing C-class flares.

The LS100T/Ha is a complete Solar Telescope. The refractor based system has a precision aligned singlet chromatic lens with a 100 mm aperture. The front singlet lens reduces the stray-light over an achromat by half. With the matched collimation lens set, it also fully corrects on axis coma, astigmatism and de-centering aberrations and provides a full spherically corrected flat-field Solar-Telescope. The focal length is 800 mm providing a ~7.3 mm image thru a 12 mm blocking filter. Course focus adjustment is via a slide tube. Focusing is achieved with a High Precision 2″ Starlight Feather Touch Friction focuser with the a 10:1 reduction as standard equipment.
An internal etalon with tune adjustment allows for a <0.7 Angstrom bandpass.

Addionally the system may also be purchased with the 100mm external, front mounted Double Stack Etalon LS100FHa for a bandpass of <0.5 Angstrom.

True Doppler Tuning allows for a shift into and away from the user.  Adding a 3D like component to the viewing experience. While it has minimal effect on proms due to their being at the edge of the disk, it does have an effect on filaments and active regions on the surface.  While looking at a filament at the center of the Sun the user has the ability to Doppler shift from the base of the filament to the tip, following the filament thru it’s structure toward you and away from you. Allowing for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist.  The pressure tuning system provides an order of magnitude more precision to the tuning of the desired features.

The sun has truly started to kick up in activity over the last few days.  Yesterday many observers woke to the news that an X2 class flare had emitted and now today a second region of sunspots has come into view.  Solar observers and images are urged to go out and take a look!  Here are so images captured yesterday morning with an LS100THa and DMK41.

Last month imager Brain Johnson tested out his brand new B3400 blocking filter on his LS100THa and boy did he use that blocker to its full potential!  The B3400 is currently the largest blocking filter in the Lunt family, this massive blocker is designed inside a 2″ straight through barrel allowing the largest of CCD cameras to be used!  For the shot below Brian used the famous SBIG STL-11000 CCD camera that sports an awesome full frame CCD sensor.  The field of view (FOV) is huge, its large chip allows Brian to image the entire solar disk in one shot!

Brian’s image shows an extremely detailed solar disk with two large active regions, a sun spot, and countless filaments!

Thanks for sending in your image Brian!
