Huey Alvin. Observing planetary nebulae and supernova remnants

Rev. Sept 15, 2010. — 325 p.On the upper left, the naked eye field with the TelRadTM recticle is superimposed on the Planetary Nebula. The bottom chart is a finder field about 4.8є across and 3.0є high. The finder field is wide enough for the finder scope and detailed enough for those who choose to use a low power eyepiece as a “finder”, like I do. The limiting magnitude of the field stars is set to 11.0, unless noted.
On the upper right, the negative DSS image is provided. The field is generally 15.0’ square unless noted. The field size of the image is overlaid on the
finder chart.
The images are oriented north pointed up and west to the right. A table is provided below giving some basic information of the Planetary Nebula.
