NEW! Image by Ron Brown During the last week of October 2014 a huge sunspot appeared. The complex was larger than the planet Jupiter and was visible to the naked eye. This photo was taken with a cell phone looking into a 20 mm eyepiece plugged into a 114 mm f8 Celestron Starseeker telescope. |
Images by Steve Luzader I've been learning how to do more with Registax to process images from my Orion Starshoot 3 camera. Below are several images taken during late May and early June 2012. All of the pictures were taken with the camera mounted in a diagonal, so they are all mirror-reversed. |
Venus at about 8:50 PM on May 31, 2012. On June 5, Venus will cross the face of the sun. Since Venus is now very close to the sun in the sky, it appears as a thin crescent in a telescope eyepiece. This photo was taken from the Mountain Ridge High School parking lot, which is one of the locations where we plan to observe the beginning of the transit. The photo was taken with a Canon 40D on a Celestar 8 f10 sct. The exposure was 1/320 sec at ISO1600. The camera was tilted, so this image was cropped from the full frame and rotated so the horizon was horizontal. |
This picture of the early stages of the annular eclipse of May 20, 2012, was sent to us from Houston, TX by Xi Chen, a former Frostburg State University student. |
Image by Steve Luzader A 22 degree circumsolar halo observed around noon on May 12, 2012. I was surprised to see this in the spring. These halos are caused by ice crystals high in the atmosphere, and the only other time I've ever seen one was on a brutally cold December day in the 1980s as I was driving through Chicago. The picture was taken with a Canon 40D with a 17 - 50 mm lens set at 17 mm. The exposure was 1/1600 s at f20, ISO 400. |
Image by Steve Luzader Solar prominences photographed on July 19, 2011, through a Meade SolarMax 60 telescope. A Canon 40D with a 28 - 135 mm zoom lens set at 28 mm pointed into an 18 mm eyepiece. The exposure was 1/250 sec at f13, ISO 800. The image was cropped from the full frame and was enhanced to bring out details that were visible in the eyepiece. In addition to the prominences on the limb, a prominence erupting toward earth can be seen near the center of the disk as a dark sinuous feature. The lighter area near that prominence was a large sunspot complex seen in visible light. |
Image by Mark Rudy The feaure at the southwestern edge of Sinus Iridum known as Promontorium Heraclides, but which is also called "The Lady in the Moon" as related in the September 2010 issue of Sky and Telescope. The image was taken at Stars in the Park on Saturday, June 11, 2011, at the Glendening Recreation Complex in Frostburg, MD, with an Orion Starshoot IV imager attached to a 12.5"f5.4 Newtonian. Approxmiately 50 frames were processed with Registax 5 to create the final image. |
Image by Mark Rudy The crater Copernicus with Rheinhold and Lansberg below. The ray system is prominent in the image, which was taken on April 14, 2011 with an Orion Starshoot IV imager attached to a 12.5"f5.4 Newtonian. Approxmiately 100 frames were processed with Registax 5 to create the final image. |
Image by Mark Rudy The craters Aristoteles and Eudoxus, with Plato shadowed on the terminator. Montes Alpes and Vallis Alpes are prominent because of the sun angle. The image was taken with an Orion Starshoot IV imager attached to a 12.5"f5.4 Newtonian. Approxmiately 150 frames were processed with Registax 5 to create the final image. |
Image by Mark Rudy This sunspot group was photographed at about 3 PM on March 12, 2011 with an Orion Starshoot IV imager. The exposure was 7 seconds at 30 frames per sec. The resulting 2100 frames were processed with Registax 5. The telescope is a homemade 12.5 inch f5.4 Newtonian masked to 4 inches with a homemade Bader filter. |
Images by Steve Luzader These images were taken on Oct. 27 and 28, 2010. Compare them with the Oct. 24 image below. The pair of sunspots has been joined by a larger spot, which moves from one day to the next. Each picture is a superposition of three images taken through my 80 mm f7.5 apochromat fitted with a homemade filter. From the Oct. 27 image, I estimate the diameter of the largest spot to be just under 31,000 km, or about 2.5 times the diameter of the earth. |
Images by Steve Luzader These images, taken on Oct. 22 and 24, 2010, show our dynamic sun. Three sunspots were observed on Oct. 22. The next day, when CAC was participating in the Science and Engineering Festival on the FSU campus, we saw that several smaller spots had appeared near the large one at the apex of the triangle in the Oct. 22 image. On Oct. 24, a new large spot had appeared at the apex and a pair of smaller spots could be seen between the apex and the spot at the upper left of the triangle. (And of course the entire group is moving as the sun rotates.) Both images were taken with a Canon 40D SLR. The Oct. 22 picture was taken through my 80 mm f4 ShortTube refractor, and the Oct. 24 picture was taken through my 80 mm f/7.5 apochromat. The Oct. 24 image was reduced by 2/3 to match the scale of the Oct. 22 image. While observing the sunspots, we also looked at a large prominence through FSU's PST40. Within less than 30 minutes, that prominence had completely disappeared! |
Image by Steve Vincent This is an eyepiece view of the sun at H-alpha wavelength taken through a Coronado PST40 on Sept. 11, 2010, during Astronomy Weekend at Blackwater Falls State Park in Davis, WV. A large prominence is visible. Careful observers noted significant changes in the prominence over a period of an hour or so. |
Images by Steve Luzader After a long period of quiescence, sunspots are returning. Clicking on the thumbnail will bring up a sequence of images taken on Sept. 22, 23, and 24, 2010. You can see how the spots move across the face of the sun. The lower spot has changed shape during the three day period. Click here to see a sequence of closeups showing the evolution from a spot with two distinct umbrae to a single umbra that looks like Mickey Mouse. Measuring the size of the spot in the image allows me to infer that the spot is about 40,000 km wide by about 28,500 km tall. That means six earths could fit into it! The images were taken through an 80 mm Orion ED refractor with a homemade filter. The Sept. 22 image was taken with a digital point-and-shoot camera looking into the eyepiece. The other images were taken with a Canon 40D SLR attached to the telescope. The filter was made by cutting a hole in a plastic bowl that just fits over the end of the telescope and taping a piece of Baader solar filter material over the hole. Works quite well! |
Image by Mark Rudy This is an eyepiece view of the chain of sunspots in the Sun's northern hemisphere visible in the photos above. The image is a combination of two shots taken with a Fuji digital camera set for 1/250 sec at f4.2, ISO 400, at a focal length of 71.2 mm. These pictures were taken on Sept. 25, 2010. |

Image by Mark Rudy The region around Copernicus on the moon. The image is a stack of four separate exposures processed with Registax. The view is inverted as seen in the eyepiece of a Newtonian telescope. |
Image by Steve Luzader A composite of two digital camera images taken about 40 minutes apart showing the region around the Apollo 17 landing site on the moon. The circle in the left-hand image marks the approximate region where the crew landed. Note how the shadow cast by Mons Argaeus shorted during the interval between the exposures. The large crater at the top is Posidonius. These images have been adjusted to show the correct orientation. The actual eyepiece view was the mirror image of what is shown. |

by Steve Luzader Mars as seen about 11 PM on September 15, 2003. The image is comprised of 14 STV exposures processed and combined with AIP4WIN. Because the Martian day is about half an hour longer than an earth day, observing at the same time every night brings a slightly different part of the surface into view. Mare Cimmerium has moved to the west edge of the disk, and Tharsis (location of three huge volcanos) is visible at the eastern edge. This picture is larger than the one from September 10 because only the central quarter of the STV frame is used. |

Image by Steve Luzader Mars as seen about 11 PM on September 10, 2003. The image is comprised of 14 STV exposures processed and combined with AIP4WIN. By using a 2X Barlow, my 8-inch SCT was operating at f/20. The orientation is true, with north up and east to the right. Syrtis Major is visible at the far west side, with the Hellas impact feature visible just below Syrtis. The southern polar cap, which had shrunk dramatically over two weeks of observing, is visible. Click here to see a picture identifying some of the features that can be seen. |

This is an STV image of the sun showing the same group of sunspots just after the disk of the moon had crossed during the solar eclipse on Christmas Day, 2000. The image was made at approximately 1:12 PM in Salem, WV. The camera wasn't attached to the telescope in the same orientation as the previous image, so this picture was rotated to more closely match the earlier one. The dark area in the image is an artifact probably caused by "blooming" in the CCD chip. The telescope used was an Orion 80 mm f/5 "Shorttube" refractor fitted with an aluminized glass solar filter. |

Clicking on the thumbnail brings up a montage of three STV images of the Christmas 2000 solar eclipse. The images were captured over a 6-minute interval as the disk of the moon uncovered a large group of sunspots. The approximate times are given below each image. The camera was removed between the second and third images, so the third image was rotated to have the same orientation as the other two. The eclipse was observed in Salem, WV. The telescope used was an Orion 80 mm f/5 "Shorttube" refractor fitted with an aluminized glass solar filter. |

For Christmas 2000, my wife and daughter presented me with a wonderful new toy--an SBIG ST-V CCD imager/autoguider. It arrived on December 12, 2000, and I tried it out that evening in spite of temperatures below 20 F. This picture of the moon is the first image I took with the STV. The picture was taken with the camera attached to my 80 mm "Shorttube" refractor (with no clock drive). The exposure was 1 millisecond with a 20X filter in front of the CCD. |

This pair of images shows Venus in its gibbous and crescent phases. Seeing Venus going through a cycle of phases like the Moon helped convince Galileo that the planets in the solar system were orbiting the sun, not the earth. Both photos are by eyepiece projection using a 10 mm eyepiece in an Orion adjustable telextender at maximum length for greatest magnification. The resulting small image on the 35 mm slide was cropped and enlarged for display. Both exposures were about 1/2 second and were made by holding a large piece of cardboard in front of the telescope to act as a shutter. The cardboard was yanked away and put back as quickly as possible. The gibbous phase was photographed Oct. 3, 1997, on Ektachrome 100 film. The crescent phase was taken Dec. 28, 1997 on Fujichrome Sensia 100 film. |

This piggyback photo shows Jupiter, Venus, and Mars at about 6 PM EST on Dec. 16, 1997. Jupiter is in the upper left corner of the image, Venus is the very bright object, and Mars is to the right of Venus, about a third of the way up from the bottom. The image is tilted because of the orientation of the camera on the guiding telescope. These bright planets were lined up just below the ecliptic that evening. Neptune (magnitude 8) was just to the west (right) of Mars, but is lost in the skyglow. Uranus was about a third of the way between Venus and Jupiter, and a check of the stars with the program Red Shift showed that Uranus (magnitude 5.9) was indeed captured in the image. It's circled in the photo. The exposure was 5 minutes with a 55 mm lens at f/2.8 on Fujichrome Sensia 100 film. |

Saturn photographed by eyepiece projection. A 9 mm eyepiece was used in an 8" Meade SCT to form an image on Fujicolor 400 film. The exposure was determined automatically by the camera. The image shown was cropped from a small portion of a print, causing the displayed image to be a little grainy. The print was also very light, so the brightness and contrast were changed for the displayed image. |
