Me & the Equipment:
60mm Takahashi Refractor Telescope with a 355mm Focal Length option, Camera-Imaging Source/Celestron 1600x1200 Skyris Camera, Takahashi Teagul Equatorial Mount, It's weight is a mere two pounds. It's weight makes it excellent for use on the Teagul Equatorial Mount. It is also excellent as a traveler for future A modification of the Focuser was made to make it a 2 speed. Image of the Telescope shows a 1600x1200 pixel Imaging Source/Celestron Skyris "Planetary Camera." This Telescope can be used for observing. A 24mm Televue Panoptic provides 14x with a 4.9 degree field of view. |

The Objective was to capture detail of
the Inner Corona as well as Promenence detail, but still trying
to capture some of the "inner" Outer Corona. Close up
imaging would give the best detail. Using the Takahashi
60, I have a choice of 3 focal Lengths. A Focal Reducer
gave me 256mm. A 1.04x Field Flattener gave me 372mm.
Np attachments gave me 355mm. The decision was not easy.
I choose no attachments. I felt it would give me enough
Outer Corona and still get nice Inner Corona detail.
It is safe to default to the middle choice. The Takahshi 60 was recently purchased for it's light weight and compact design. It is also compatible with the existing Takahashi Teagul Mount. This will be the Telescope used for excursions requiring Air Travel. |
The Profile image is an mage of 10 images with 10 different exposures. They were interpolated to a higher resolution, then Smart Stacked. The image was enhanced using the Camera Filter in Photo Shop. A grey "overlay" was added/blended for contrast. Then a fast exposure showing an Inner Corona detail was added and blended at 50%. The base image was brightened, and then the two images were flattened/merged. The combined images were then slightly enhanced with the Camera Filter in Photo Shop. The final imaged was further enhanced in cuves, by pulling the upper line to the right slightly. This created the desired contrast. Experimentation was the main method before the final method was developed and used. |
