The 6mm Blocking Filter provides almost 1mm of area around the Solar disk. A smaller Blocking Filter would cut off the image and would not allow for a full disk view. A smaller Blocking Filter would also cause significant uniformity issues at the edges. A slightly larger (one size up) is always recommended whenever the user intends to do imaging, manual tracking, or requires a larger field of view for increased visual comfort and Solar edge contrast. One size up is the minimum recommended size. Depending on the size of your scope and the type of camera you may want to chose 2 step higher Blocking Filter. The advantage of getting a larger Blocking Filter for imaging use now is that, a) it removes the need to upgrade later should you decide to image later, and b) it provides more wiggle room around the Blocking Filter in Visual mode. (There is more dark space around the Sun when viewing). This also has the advantage of not having to adjust the mount as often when tracking manually. To pick the proper blocking filter for you, take a look at the suggestions listed below for visual use and\/or imaging use. Next, match what you want to do with the focal length of the telescope you will be using for solar work.\n\u003cp data-mce-fragment=\"1\"\u003eFocal Length Suggestions for Visual Use:\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eB600 : For visual use on telescopes with focal lengths up to 600 mm\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eB1200: For visual use on telescopes with focal lengths up to 1200 mm\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eB1800: For visual use on telescopes with focal lengths up to 1800 mm\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eB3400: For visual use on telescopes with focal lengths up to 3400 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eFocal Length Suggestions for Imaging Use:\u003c\/strong\u003e\u003c\/h4\u003e\nWhen imaging with a Lunt Solar System it is recommended that the user opt for the next larger blocking filter than that recommended for visual use.

The 6mm Blocking Filter provides almost 1mm of area around the Solar disk. A smaller Blocking Filter would cut off the image and would not allow for a full disk view. A smaller Blocking Filter would also cause significant uniformity issues at the edges. A slightly larger (one size up) is always recommended whenever the user intends to do imaging, manual tracking, or requires a larger field of view for increased visual comfort and Solar edge contrast. One size up is the minimum recommended size. Depending on the size of your scope and the type of camera you may want to chose 2 step higher Blocking Filter. The advantage of getting a larger Blocking Filter for imaging use now is that, a) it removes the need to upgrade later should you decide to image later, and b) it provides more wiggle room around the Blocking Filter in Visual mode. (There is more dark space around the Sun when viewing). This also has the advantage of not having to adjust the mount as often when tracking manually.

Meanwhile it has minimal effect on proms due to their being at the edge of the disk, it does have an effect on filaments and active regions on the surface. Also, when looking at a filament at the center of the Sun, the user has the ability to Doppler shift from the base of the filament to the tip. Therefore, you’ll be able to follow the filament through it’s structure toward you and away from you.  All of this allows for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist.
