Southern Herschel 400 Observing Program 
Targets #91-120

Addendum to the Astronomical League's Herschel 400 OP

Telescopes used:

• Many of the 150 images were taken for this observing program using the SLOOH telescopes located in either the Canary Islands or Chile.
  • The Chile Slooh telescopes are located at the Santa Martina Observatory outside Santiago at 3.269 S & 70.534 W at 4756 feet elevation.
  • The Canary Islands telescopes are located on the island of Tenerife, about 15 kilometers northeast of the volcano Teide and 300 kilometers west of the African coast at 28.29970 N  &16.50826 W at 7783 feet elevation.
  • Most commonly I used their CDK 17" telescopes, "Chile2" and Canary2" each outfitted with a FLI PL16803 camera and requested 50 second luminance images.
  • Occasionally I used their 20" CDK scope "Canary1" + FLI PL09000 or their 11" RASA scope "Canary 3" + ZWO294MC with similar short exposures.
  • Full telescope specs for all of SLOOH's telescopes are here: https://vega.slooh.com/docs/Slooh_Observatories_and_Telescope_Specifications.pdf 
• Occasionally images were taken by myself at Deerlick Astronomy Village in Crawfordvile, GA at 33.5539 N & 82.791 W at 495 ft elevation. These are indicated by "DAV" and the scope and camera used are listed with the photo.

This one does have a concentration of stars towards the center, with a mixed assortment of small to medium stars. I would estimate that it has less than 100 stars. As in the other open cluster images, some fingers of darkness swoosh through the field, helping to acentuate the cluster.

The three stars that form the other corners are almost the same size as the nebula. Sharply angled strings of stars in the field give a zig-zag look to the background. Click the photo to zoom in and you will see that the PN is slightly elongated vertically with bright aqua blue at both top and bottom ends. In front of the blue portion sits a bowtie-shaped zone of pale material.

It butts up against a velvety dark nebula, forming an impressive wall.

This cluster is a bright one, thanks to the extremely luminous double star (mags 5.6 & 8.4) that anchors it. The cluster has only a handful of stars, all sitting nearby the bright double.

Both crowd it, making it hard to see the nebula's full outline to tell if it lives up to its nickname, the Box Nebula.

Or perhaps it's rated a III because it is uniformly dense with no extreme concentration to the center? Regardless, its density does allow it to stand out well in the field despite the small size of its stars.
