Here is my set up for viewing the Sun in white light and Hydrogen alpha. The white light filter is on the TV-76, while the NP-127 has double-stacked Coronado SM-90 filters, bringing the band pass to <0.5 Å. This arrangement allows for the observation of more detail on the disc of the Sun. A single SM-90 is sufficient to see prominences, flares, etc., but the view of these with disc detail is pretty awesome. |

| I have a Gibralter mount with a custom mounting bracket which allows me to keep the dove plate mounted to the scope. Both the Gibralter and the Celestron CGE accept the dove plate, so transferring between mounts is very easy. Since I don't have an observatory (yet!) I use the Gibralter mount which is light enough for me to carry. This is o.k. for quick, visual observing just to see what's going on with the Sun. I don't think this is a suitable set-up for imaging but will try to take some shots with a DSLR or video camera and see how this turns out. |

This is the set-up I use for imaging. The CGE mount is very solid and helps to minimize vibrations from focusing, shutter release, etc. I used this set-up to take the images of the Mercury transit across the Sun on November 8, 2006. The white light images from the TV-76 can be seen here and the hydrogen alpha images from the NP-127 and single SM-90 (I did not yet have the second SM-90) can be seen here. Those of you with keen eyes may notice a viewing companion in the photo above. Move your cursor over the large rock to the left of the tripod and click on the hot spot to bring up another image of my friend.
