What this thread contains
This thread contains 14 templates of binocular FOV circles for several star atlases and one observing guide. Template 15 contains a degree rule to estimate altitude with the Night Sky Planisphere. Templates 16-19 contain star hop templates for use with the Sky Atlas 2000.0.
The FOV circle templates are scaled for the following binocular FOV sizes, atlases, observing guide, and planisphere:Binocular FOV sizes
3 degrees (Garrett Signature 22x85)
4 degrees (Fujinon FMT-SX 16x70)
5 degrees (Pentax DCF ED 10x50)
7.5 degrees (Fujinon FMT-SX 7x50)
The FOV measurement is based upon the advertised FOV from the manufacturer or distributor. True FOV measurement is usually smaller than the advertised FOV by one or more tenths of a degree.

Planisphere
Template 15
Chandler, David. The Night Sky: The Original 2-Sided Planisphere. [Degree Rule: 0-90 degrees, Scale: 0.8mm per degree]. (Springfield, CA: David Chandler Co., n.d.). How the templates were made
The templates were drafted using the drawing tools in Microsoft Word 2003, one template per file. Measurement was calculated in millimeters and converted to inches. The mm measurement below each FOV circle is more accurate than the inch (") measurement.
Each template contains a cut line that appears as a dotted line (-----) in black color. The FOV circles and text appear in red color. The color red should appear brighter than the color black with a red flashlight under the night sky.
The FOV circles can be altered to different FOV sizes. If you plan to alter the FOV size, I recommend you do the measuring in millimeters, rather than inches.
Printing the templates
The templates can be printed on overhead transparency sheets (clear) with a laser printer (e.g., HP LaserJet) or taken to a local office supply store with a print shop (e.g., Office Depot).
To print the FOV circles and text in red, I recommend taking the template file(s) on disk to a office supply store if you do not have access to a laser printer that can print color on overhead transparency sheets. Many office supply stores also accept files as attachments to e-mail.
Asking the office supply store to laminate the transparency sheet(s) after printing will make the template(s) more rigid—a perfect bookmark for the corresponding atlas or observing guide.
How to use the templates
The FOV circle templates can be used during the observation planning phase. 1. Identify the target object(s) for the evening observation.
2. Locate the target object(s) on a specific atlas by the right ascension (RA) and declination (DEC) coordinates. It may be helpful to consult star catalog references such as Vol. 3 of the Night Sky Observer’s Guide, the mini star catalogs in the Bright Star Atlas 2000.0 or The Cambridge Star Atlas, or the indexes of the Pocket Sky Atlas. You may also consult several online resources, such as the online Sky Atlas 2000.0 Companion.
3. Select the FOV circle that corresponds to the binocular(s) to be used during the evening observation.
4. Center the FOV circle on the target object(s) to provide an approximation of what will be seen through the eye cups of the binocular.
5. To position a desired FOV circles close to the edge of a chart, rotate or flip the template 90 or 180 degrees. The FOV circle templates can also be used to “star hop” from a known bright star to the unknown position of the target object(s) in the night sky. 1. Identify the target object(s) for the evening observation.
2. Locate the target object(s) on a specific atlas by the right ascension (RA) and declination (DEC) coordinates. It may be helpful to consult star catalog references such as Vol. 3 of the Night Sky Observer’s Guide, the mini star catalogs in the Bright Star Atlas 2000.0 or The Cambridge Star Atlas, or the indexes of the Pocket Sky Atlas. You may also consult several online resources, such as the online Sky Atlas 2000.0 Companion.
3. Select the FOV star hop template that corresponds to the binocular(s) to be used during the evening observation.
4. Position the desired FOV circle on a known bright star, magnitude 3 or brighter, on a specific atlas.
5. Lay a blank sheet of white paper or tracing paper over the atlas, placing orientation marks for compass points (N,S, E, W) as well as marking chart major degree lines, date, time and location of the observation.
6. Trace the first position of the FOV circle on the white or tracing paper (which is centered on the known bright star). Make sure to use a pencil or ball point pen that will not bleed through to the atlas page. If the "star hop" field chart will be used by itself (without overlaying onto an atlas in the field) it may be helpful to mark the nearby locations of bright stars (magnitude 3 or greater) and unusual star formations.
7. Move the FOV circle in a vertical straight line, overlapping slightly the edge of the FOV circle to the previous position.
8. Trace the second position of the FOV circle on the paper, as well as bright stars and unusual star formations inside each FOV circle.
9. Continue to move the position of the FOV circle on the atlas and trace the new positions onto the paper, as well as bright stars and unusual star formations. The line of FOV circles on the paper will be the “star hopping” field chart to use during the night observation.
10. Try to approach the target object(s) by aligning the traced FOV circles at right angles: First vertical movements toward the object(s), then horizontal movements. Some observers find that moving across the night sky with vertical and horizontal movements may be easier under the night sky than diagonal movements. Star hop templates
After I posted the original templates, it occurred to me that star hop templates for the very popular Sky Atlas 2000.0 may be of some benefit. So I posted four additional templates (#16-19).
These star hop templates can be used in a couple of ways. Use # 1
Print out several copies on overhead transparency sheets (clear) and use as overlays to the atlas you will be taking to the field under the night sky.
1. Identify the target object(s) for the evening observation.
2. Locate the target object(s) on a specific atlas by the right ascension (RA) and declination (DEC) coordinates. It may be helpful to consult star catalog references such as Vol. 3 of the Night Sky Observer’s Guide, the mini star catalogs in the Bright Star Atlas 2000.0 or The Cambridge Star Atlas, or the indexes of the Pocket Sky Atlas. You may also consult several online resources, such as the online Sky Atlas 2000.0 Companion.
3. Select the FOV star hop template that corresponds to the binocular(s) to be used during the evening observation.
4. Position the desired FOV circle on a known bright star, magnitude 3 or brighter, on a specific atlas.
Once you have the overlays and atlas oriented to the compass points (N,S, E, W), you may want to use an erasable transparency marker to place orientation marks on the transparency sheet, as well as the date, time, and location of the observation.
Of course, a permanent marker could be used if you wish to keep a separate star hop sheet with your star logs. Doing this for some of the Messiers may be of some benefit.
Use # 2
Compare the number of hops required to get from the known bright star to the target object(s), depending upon the FOV size of the selected binocular. Therefore, larger FOV circles (lower magnification) require fewer star hops. One rule to bear in mind when you are learning where an object is in the night sky--fewer hops usually make things go easier and quicker.
