The Cuyahoga Astronomical Association (CAA) has several skilled photographers amongst its membership. Taking advantage of a clear, starry night February 6, CAA member Alan Studt spent some time with his camera making this wonderful image. Creating an image as beautiful as this nighttime landscape isn’t as simple as simply pressing the shutter release, even on an advanced DSLR. Here are Alan’s notes concerning this photograph:

The image is a combination of a few shots to get the various dynamic ranges involved.

Camera – Nikon D600 with 14mm Rokinon lens, producing three shots processed in Adobe Lightroom CC, and layer blended in Adobe Photoshop CC:

  • Sky – ISO 1250, 15 seconds, f/2.8
  • Land/Lights – ISO 6400, 15 seconds, f/22
  • Lake/Boardwalk – ISO 1000, 15 seconds, f/2.8

Constellations and objects seen in this image include: Canis Major & Minor, Orion, Lepus, Taurus, The Pleiades, and the lower part of Gemini in the upper left corner.

An impressive train of sunspots has been making its way across the face of our nearest star this week. In the photo above: Designated AR2447 (small group to the left), AR2443 (bigger and darker, near center), and AR2445 (far right), the “Active Regions” have the potential of unleashing flares. In fact, AR2445 was the source of a flare that caused this week’s “northern lights” sighted across northern latitude locations around the world. Now rotating over the Sun’s limb, AR2445 won’t be aimed at Earth for a while — if ever again — but AR2443 has potential for high-energy flares.

The Beautiful “Gulf of Mexico”

“Gulf of Mexico” Region of NGC7000

CAA member and local astronomy business owner Joe Golias has shared a new image with us that, well, all we can say about it is that it’s astounding! Here’s Joe’s description of how he produced his photograph of a region of NGC7000…

This was by far the most challenging imaging project I have attempted to date. It represents a four-panel mosaic of an area called the “Gulf of Mexico” which is part of a much larger area of nebulosity called The North American Nebula or NGC7000. This object is located in the constellation of Cygnus. This four-panel mosaic was acquired over a period of three weeks. Total exposure time was 56 hours. We’ve had a long stretch of clear skies here in Ohio which made this image possible.

Object: Gulf of Mexico | Telescope: Takahashi TOA 150 refractor | Telescope Mount: Losmandy G-11 | Camera: SBIG STT8300 with self-guiding filter wheel | Exposure: 56 hours of combined narrowband HA, OIII & SII filters | Location: “Astrozap Ridge,” Medina, Ohio. | Image processing: MaxIm DL, Images Plus, PixInsight, Photoshop CS6

CAA’s 2015 Astrophoto Show
CAA’s astrophoto display is now up and running on the Gallery Wall at the Rocky River Nature Center!  Come and see the excellent work done by our members! The display is from September through October 2015.

Thanks to Steve Gallant, Dave Watkins, Dave Nuti, James Guilford, Chris Christe, Steve Spears, Alan Studt , and Joe Golias for providing photos for the display. We had more photos than we could fit on the Gallery Wall, so we mounted some images on nearby walls in the gallery room.

Unfortunately, due to a lack of room not all the images could be displayed. I helped hang the photos, however, and made sure that everyone who submitted images was represented. Thanks again to everyone for participating!

A most memorable vacation photo

Cuyahoga Astronomical Association member Alan Studt captured this wonderful photo of our home galaxy, the Milky Way, under some fairly challenging circumstances the night of May 23. He and his wife, Gale, were on vacation in Massachusetts when a celestial photo op presented itself.

“That … night happened to be the only clear night in the forecast during our vacation so I had to check it out. We were staying about six miles east of Hyannis in West Dennis, just a five-minute drive from the south shoreline of Cape Cod.

“The beach parking lot gates get locked at midnight and the ‘Teapot’ in Sagittarius didn’t clear the horizon until 11:45, so I didn’t have a lot of time to shoot. I didn’t know where else to go to stay out later until the Milky Way was higher so I had to to accept what I could get.

“The weather conditions were not great. Temps in the mid-40s with at least a steady 25 MPH wind gusting to 35 MPH. Gale thinks it was faster since the car was shaking when she went back in to wait for me. My tripods blew over before I hung bags with bottles of water, extra lenses and shoes on them… the cameras were not attached at the time.”

So, even under pressure of time and weather, Studt came home with something truly out-of-this-world as a memorable vacation photo: a sea of stars!

Studt’s Photo Notes: Looking out over Nantucket Sound/Atlantic Ocean. Three horizontal shots layered together in Photoshop. 90-degree view – east to south. Taken at West Dennis Beach, Massachusetts on a very windy evening just before midnight. The lights in the distance on the right are from Nantucket Island, 30 miles south. On the left, down at the end of the beach is The Lighthouse Inn, an old lighthouse that is now a restaurant. There was a waxing First Quarter Moon about — maybe 30 degrees — above the horizon in the west. Nikon D600, 24mm, f3.5, ISO 6400, 20 seconds. Processed in Lightroom & Photoshop CC

First Public Star Party of 2015

Saturday night, May 23, the Cuyahoga Astronomical Association (CAA) held our first Public Star Party for 2015. The event took place at the club’s observatory situated on the grounds of the Medina County Park System’s Letha House Park in Spencer, Ohio. Members of the public were generally enthusiastic, excitedly moving between telescopes. The sky was beautifully clear and allowed excellent views of the Moon, Jupiter, Saturn, Venus, the Hercules Star Cluster (M13), M81 & M82, and other astronomical wonders.

CAA President William Murmann wrote, “Thanks to everyone who attended and who brought scopes to help with the program!

“The park staff said we had about 50 guests join us, including families with children.  We had clear skies all day, but some high, thin wispy stuff moved in during the evening, although we had good observing.

“It was nice to see to James Guilford, Steve Spears, Chris Christe, Chris Burke, Paul Leopold, Suzie Dills, Trevor Braun, Bob Wiersma, Jay Reynolds, Rich Rinehart, Bill & Carol Lee, Tim Campbell and Mary Ann, Steve & Gail Korylak, Rich & Nancy Whisler, Dave & Jan Heideloff, Carl Kudrna, Larry Smith — and new member Anita Kazarian, who joined us.  Sorry if I missed anyone.

“Noteworthy for the evening–Steve Korylak spotted Comet Lovejoy with his scope.

“It was a nice program and a nice get together for members.  Thanks again.”

Among the objects the public viewed in beautiful detail was Earth’s Moon. Early in the evening not only could observers see the brightly-lit portion of the Moon but also the Earth-lit shadowed portion of the disk. Adding to the scene was a beautiful speck of a star near the horn of the Moon: Acubens, a star in constellation Cancer.
