The Sun is our Star!

.......and as you would expect, our Star is hot, bright, dynamic, and sometimes quite violent.

At 93 million miles away, we are ideally placed at a point where the Sun provides just enough warmth and energy essential to our living planet, Earth.
At only 93 million miles, the Sun is close enough for us to view it's surface thru a relatively inexpensive scope from the comfort and relative safety (Sunscreen please) of our backyards on a clear and warm day.

What! Astronomy during the day? Lunt Solar wants to show you how.

Prominences:
These look like eruptions from the edge of the Solar disk. Prominences can be small spikey looking details, or large cloud-like detail with fine feather-like features.

They are, in fact, ionized Hydrogen-alpha emissions being projected from the linb.

Prominences are anchored to the Sun's surface in the Mesosphere, and extend outward into the Sun's Troposhere.
They typically measure many earth diameters.

Filaments:
These are strin-like features on the surface of the Sun.

At high resultion they take on a 3D effect due to the coller aspect of the suspended filament contrasted against the bright, hotter Sun.

They are actually prominences being viewed against the surface.

Spicules
A Spicule is a dynamic jet of gas about 500km long.
They move outward at about 20km/second thru the Chromosphere.

Father Angelo Secchi of the Vatican Observatory discovered them in 1877.

The Chromosphere is entirely composed of Spicules. These features can be seen as "fur"around the edge of the disk.


There's definately stuff to look at :)

We are excited to announce that Lunt Solar is entering Imaging!

We get asked all the time what camera is best with the Lunt Solar scopes and
filter now we can say ours. Below are the details of the new Lunt Solar
Imager (LSi). We have these ready for immediate delivery.

The price is $2,295.00.

Lunt Solar Imager

(as used on National Geographic’s, Easter Island Eclipse)

Includes the Lunt Solar Imager (LSi), Custom Lunt Solar Software (also
compatible with standard nighttime software for night use), and Lunt Solar
imaging instructions for use with the Lunt Solar scopes.

CCD type: Sony ICX285AL Exview HAD CCD with ultra low dark current, extended IR response and vertical anti-blooming.

CCD quality: Grade 1 or better – No bad columns, no dead pixels, no more
than 6 ‘hot’ pixels (saturated in <10 seconds).

CCD Full resolution Pixel data: Pixel size: 6.45uM x 6.45uM, Image format: 1392 x 1040 pixels

CCD Image area: 8.98mm (Horizontal) x 6.7mm (Vertical).

Spectral Response: QE max at 540nM (~65%), 50% roll-off at 400nM and 750nM.

Readout Noise: Less than 7 electrons RMS – typically ONLY 5 electrons! 

Full-well capacity: Greater than 23,000 e- (un-binned)

Anti-blooming: Overload margin greater than 800x.

Dark current: Dark frame saturation time greater than 100 hours. Less than
0.02 electrons/second @ + 10C ambient.

Data format: 16 bits.

System gain:  0.45 electrons per ADU

Computer Interface: Built-in USB 2.0 compatible interface. 

Image download time: Typically 0.6 seconds full resolution using USB 2.0,
approximately 2 seconds with USB 1.1.

Power requirements: 115VAC / 240VAC @ 12VA, or 12VDC @ 750mA max.

Cooling system: Regulated set-point cooling supply with single stage
thermoelectric cooler to give a CCD temperature of up to -30C below ambient.

Size: 75 x 70mm red anodized aluminum barrel with 42mm ‘T2′ thread at the
CCD window end & input/output plugs at rear.

Weight: approx. 300g

Lunt will provide full support and instructions for Solar Imaging.

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.

June 1st, 2011

For the last few weeks the sun has grown quiet again.  After spoiling many of us with awesome active regions, prominences, filaments, etc…  Well over the last couple days the sun has unleashed a angry display with AR1226 and AR1227 which has unleashed several C-class flares!  Solar observers around the world are urged to keep the scopes trained on the sun for the next several days.

Stephen Ramsden of the famous non-profit Charlie Bates Solar Astronomy Project snapped these two amazing images this morning using some of his personal Lunt gear.

This awesome image was captured with Stephen’s LS80THa single stack and a DMK41.  Detailed views of prominences, active regions and filaments can clearly be seen across the solar disk!  While things in H-alpha looked awesome the view in white light was also quite a sight!  The image below was captured using an Explore Scientific 127ED Triplet Apo. refractor using the Lunt 2″ Solar Wedge and DMK41 camera.  The crisp views of the granulation and awesome detailed images of the collection of sunspots makes this a truly awesome image!

For more information about Charlie Bates Solar Astronomy Project and the famous S.U.N.S.P.O.T. truck check out www.charliebates.org!

We truly enjoy seeing the images being shot with our products!  Please continue to keep sending in you images and we will put them on our blog.

The sun has slowly been starting to kick up once again and imagers across the globe have been capturing amazing shots!

Peter Desypris of Greece shot these awesome up close images using his LS60THa Double Stack.

Please keep sending in your images and we will post them here on our blog!

February 16th, 2011

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.
