Herschel II Observing Program
The
Herschel II Observing Program was conceived, compiled and written by Carol Cole and Candance Pratt of the Rose City Astronomers of Portland, Oregon, USA.
The Herschel II objects are selected 400 deep-sky objects based on the 2478 Herschel Objects.
The Herschel II is an
Astronomical League certificated observing program.
Equipment
This is David Haworth's Herschel II observing index. Observing equipment used was a
Celestron
C-8 (#11023) Schmidt-Cassegrain telescope with
Fastar lens accessory (#94180) and
SBIG ST-237 CCD camera.
The observations were taken at a home observatory located in Camas, WA next to Portland, Oregon.
The image scale is the same for all the images and these images provide a good way to compare the sizes of the Herschel II objects with each other.
Manual Search Method
The following manual search method was used to located the Herschel II objects.
First, the Herschel II index at
http://www.rca-omsi.org/rca/herschl2/homepage.htm
is used to select the Herschel II object.
Secondly,
TheSky V5
is use to find the object's location. The TheSky V5 is used at the telescope and provides DSS images of all the Herschel II objects. Also, it has a mirror feature that matchs the ST-237 image. Next, the
Orion Telescopes & Binoculars EZ Finder Reflex Sight is used to aim the the telescope at a 4th magnitude or brighter star that is close to the Herschel II object. Next the Lumicon 80mm right-angle Super-Finder with correct left-right erect diagonal with about 3 degrees field of view is used to star hop to the Herschel II object's location.
The ST-237 is capturing images every 3 seconds in a 3 bin mode and is used to center the Herschel II object. Finally, a sequence of 30 second unguided images are taken of the Herschel II object.
