LOOK AGAIN !!!!! The next generation of Solar telescopes continues to Evolve…
Here is a bit of info… The image is shown with the optional DSII added.
1) The DSII will soon be available on ALL Lunt dedicated scopes including the LS152T!!
2) This same module will also be available as a rear end addition to the Celestron C11 and C14. This package will include the Lunt True ERF to safely aperture the scope to the appropriate size, removing both UV and IR energy from the optical path. A straight thru BF will be integrated into the module for enhanced viewing.
The LS80T/PT (pressure tuned) is a complete and dedicated Solar Telescope with an Image Scale of 408. Image scale is calculated by the effective image size at the focal plain and the clear aperture of the scope. A precision aligned ED refractor with a fully un-obstructed 80mm optical aperture. This package provides a significant step up into the Intermediary category of Daytime Solar Observing, Maintaining the most advanced technology of Doppler True Tuning for fine adjustment of the center wavelength, allowing research of the Sun’s disk and surface details at increased image scale. Prominences, flares, super granulation, filaments, and active regions will be observed.
The LS80T package is fully upgradeable with several options including the NEW evolutionary Dual Internal Stack Etalon System (DSII). The DSII eliminates the need for an external doublestack etalon reducing cost and eliminating obstructions. The system is 100% un-obstructed. The bandpass is reduced to <0.5 Angstroms. See the Sun’s weather in stunning high definition.

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 been in a deep slumber for the past several years, showing very little signs of activity. Lately this sleeping giant has begun its journey towards what could be a very impressive solar max. Over the past view days I have seen countless images of several massive filaments and the activity around sunspot 1092.
Below is an image from solar imager Rick Trommer. Rick captured this impressive image with his LS60THaDS50. The two massive filaments can be seen as two snake like bodies on the right while in the bottom left sunspot 1092 is quietly gliding across the solar disk.
Be sure to keep an eye on sun as things are just starting to get interesting again! Please keep sending in your images!

This past Saturday was the SCAE at Oceanside Photo and Telescope! Thank you to all who came out and saw the Lunt booth!
The event has been given a small write up and some photos in the North County Times. Check it out!: LINK

Lunt Solar Systems will be attending the SCAE event at OPT in Oceanside, California this Saturday, July 17th, 2010! If you are in the area please stop by and take a look through our scopes! Andy Lunt will be giving a talk about his recent eclipse trip to Easter Island. Come see him talk and answer any questions you may have!
Hope to see you there!

…”two students on tour with associate IFA director Mike Maberry looking on. This is from the 1st observatory built on Haleakala in 1957, the Baker-Nunn. Here’s a photo alone on top of a 10,000ft volcano”….
We are very pleased with the feedback we are getting about the Lunt 152mm Solar Telescope. This scope has certainly re-invigorated my appreciation for Solar observing, and not just daily testing. I have been very pleased with the performance of this system even under less than ideal conditions.. It is making me re-think the current convention that 4″ apertures and over suffer badly with seeing conditions..
….” took the LS152 to the summit and it seemed to perform the same as on my deck at 1600 ft. When the seeing at altitude was good, very fine details could be seen though seeing was not good enough for magnification over 200X (that’s a 4mm eyepiece ;). It was also a fortunate thing that I was up w/ the LS152 as we had a group of students on tour of the observatories. When kids come up they only get to look at large telescopes and see the observatories BUT having the scope set up and on the sun they actually got to look thru a telescope and see something..”.
They will be attaching a camera to the system very soon. We are all looking forward to seeing some first light images thru the scope..
