Southern Herschel 400 Observing Program 
Targets #121-150

Addendum to the original 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 and cameras 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.

Target Name	NGC 6541		Center (RA, hms): 18h 08m 04.656s Center (Dec, dms): -43° 43' 02.356" Size: 37 x 37 arcmin Radius: 0.436 deg Pixel scale: 1.91 arcsec/pixel Orientation: Up is 359.5 degrees E of N	SLOOH Chile2 20240120_084222 NGC 6541 is a pretty globular cluster with a condensed core that at first glance appears unevenly bright. Zooming in, we see that the uneven appearance is due to an arc of bright halo stars curling out and around the core starting at about 7 o'clock, almost like an arm. The bright star at the top right is the mag 5.6/5.6 double HR 6750.

Despite the amazingly crowded field, it is easily spotted right in the center due to its color and shape. It is pale grey/blue and spherical with 1 or 2 stars seen in the interior shen zoomed in.

(It appears in other online images.)  Another smaller reflection nebula sits below it to the left. Bright red emission nebula IC 1284 anchors the image at the lower right.

Only a handful of brighter stars are scattered about. The cluster has a slightly higher star density, so can be detected fairly easily in this ½° field. Within the cluster itself there is no specific condensation, only some tight arcs of little stars.

Zooming in will show it better. It looks as if wind is blowing gas from the right star towards the left star. There's a lot to look at in this field because just above it we also have the two paired reflection nebulae NGC 6729 (yelowish, top) and NGC 6727 (bluish, bottom). At the top right of the field sits our previous target, the nice glob NGC 6723. At the lower right edge of the frame we find bright mag 5 star, ε Coronae Australis. And last but not least, an immense upside down "V" of dark nebulae covers at least a third of the field.

The other two in the trio are spiral NGC 6770, the second object in from the left end of the arc, and NGC 6771, the edge-on spiral sitting by itself near the center of the field. Both have hazy arm-clouds and bright cores. At the bottom left of the frame sits IC 4842, a bright spiral with an elongated oval core. Be sure to zoom in and take a closer look.

I was surpised to be able to stretch this particular image enough to bring it out of hiding. It is rather amorphous, with a cacoon-like brighter section running at an angle vertically. Upon zooming in, darker streaks and patchy areas can be sensed. Due to these darker clouds, the brightness appears to drop off precipitously along the left side, but fades away more gradually on the right.

This target is perennial favorite, the Crescent Nebula. The top side lights up with lovely, red, 3D-looking clouds; the bottom side fades off dramatically before blending into the background. The bright star in the center is WR 136, a Wolf-Rayet red giant that is losing "the equivalent of the Sun's mass every 10,000 years" per Sky Safari. It might go supernova during the next million years.
