Saturn drawing templates - get them here!
      #3711257 - 03/28/10 07:44 PM Attachment (114 downloads)

Saturn season is upon us again! A few years ago I found a web site, Braye Brook Observatory, which had an Observing Saturn page.

They have a complete 1° to 28° series of .pdf templates of Saturn on that page linked to above.

Once imported into a graphics program like Photoshop one may edit out the various unnecessary CAD construction lines.
After some editing the results are a nice template for drawing Saturn. The attached example image I made is of Saturn at 3°.
Passing this image through an anti-aliasing filter would solve the jagged edges.
I import the Saturn images into Microsoft Word which adds an anti-aliasing filter to the image and smooths out the jagged edges. Then you just print out the page.

Hope this helps someone

Thanks Sky, Saturn is much easier to sketch with a template.

Thanks Tommy.

A single degree of difference is quite noticeable.
I made this animation to demonstrate how a single degree changes the appearance of Saturn significantly!





Here is a template with Saturn at 4°:

I checked The Sky software for the ring angle - Latitude of the Earth from Saturn's perspective - and obtained the following figures:

March 28 2010 = 2.9°
April 28 2010 = 1.9°
May 28 2010 = 1.6°
June 28 2010 = 2.1°
July 28 2010 = 3.1°
August 28 2010 = 4.6°

Starting around mid April people should switch to the 2° template.
So here is a template with Saturn at 2°!

I have completed editing work on all of the Saturn templates:

Saturn 00 Degrees
Saturn 01 Degrees
Saturn 02 Degrees
Saturn 03 Degrees
Saturn 04 Degrees
Saturn 05 Degrees
Saturn 06 Degrees
Saturn 07 Degrees
Saturn 08 Degrees
Saturn 09 Degrees
Saturn 10 Degrees
Saturn 11 Degrees
Saturn 12 Degrees
Saturn 13 Degrees
Saturn 14 Degrees
Saturn 15 Degrees
Saturn 16 Degrees
Saturn 17 Degrees
Saturn 18 Degrees
Saturn 19 Degrees
Saturn 20 Degrees
Saturn 21 Degrees
Saturn 22 Degrees
Saturn 23 Degrees
Saturn 24 Degrees
Saturn 25 Degrees
Saturn 26 Degrees
Saturn 27 Degrees
Saturn 28 Degrees


All 29 frames combined into an animated .gif file of only 102kb here. Looks cool!


So now everyone has access to Saturn drawing templates in 1° increments! At long last!

nice work and help. perhaps the moderator can stick them somewhere for future "generations" to use when they need them.
