Found my HorseHead finder chart

Here is a fairly nice finder chart to stash away if anyone wants to seek out this low-contrast Barnard 33 horsehead someday. Since it is a new moon weekend but is raining where I am, seemed a good time to find this chart. Each gridline is 20' apart in this image (as seen in lower left).

It is not difficult to drop south 30 min from Zeta Orion belt star and notice the 3 stars forming a high angle. Horsehead is just south of the middle star. To me it is easier to see with a 20 min field first then try other eyepieces (always with H-Beta filter) to try to get more detail.

To get a 'traditional' chart make this into a 'negative' image and set to greyscale. I like the easy and still free Irfanview program for that sort of simple and common astronomy need. http://www.irfanview.com/
