Commercial hydrogen alpha filters come in a range of clear apertures such as 40 mm, 50 mm, and 60 mm, for example. For your tablet or smart phone, give SkySafari a look. Regular monthly club meetings are held at the Keene State college. Hedgerow —This is a grouping of many smaller prominences that are likely to have come from the same source of activity.

Sketch of The Omega Centauri. Provided, however, that the quality of the optics is associated with high expectations of the resolution. About the Author Manish Panjwani has been an active amateur astronomer since before Halley's Comet last flew by our neighborhood. Further trials and experience made me prefer slits made from thick brass, which is far easier to polish and resists as much heat. Email the webmaster to report problems or suggestions.

How to Photograph a Solar Eclipse
In the early s a naturally curious fellow, Albert Ingalls, happened to read an article in an obscure magazine by an even more curious fellow, Russell Porter. The filter tuning mechanism compensates for these factors. Low power, in fact, makes a telescope much more convenient to handle, and if your telescope mount or tripod is a bit shaky, as least lower powers will not magnify "the shakes" as much. Either category can take excellent eclipse images, but the sensor size plays a determining roll on the apparent size of the Sun as seen with various focal length lenses. And nice speedy delivery The eclipse started at 1:
With the sun in the backdrop, Mr Manteca captured a passenger jet forming a subtle silhouette. Be sure that you have assembled everything with great care. For a solar, lunar and planetary observer with fixed installation a Newtonian system is well suited. These stars will still look "dot like" but instead of a single star - you will see two or more placed closely together. More resolution could only be attained at acceptable cost with mirror optics. The focal length of mm is most common among such mirror lenses and yields a great image scale for capturing solar eclipses. Certainly the most spectacular and awe-inspiring phase of the eclipse is totality.
