Cosmic Challenge: Sirius and the Pup

Feb 01 2022 10:36 AM | PhilH in Phil Harrington's Cosmic Challenge

Ask an amateur astronomer to name binary stars that are difficult to resolve and one of the most common responses will probably be Sirius, in Canis Major. While there are more difficult targets, Sirius is always a perennial favorite. The challenge comes not from the close separation of the two stars in the system, however. Rather, the challenge here is from the extreme difference in the two stars' magnitude.

Cosmic Challenge: Horsehead Nebula (Barnard 33)

Jan 01 2022 07:00 AM | PhilH in Phil Harrington's Cosmic Challenge

Let's kick off the new year with what many consider to be one of the most difficult visual challenges in the sky. If you listen carefully, you might even hear the strains of the "Mission: Impossible" theme song playing in the background. Of all the deep-sky objects in the winter sky, none carries the mystique of the dark nebula Barnard 33, better known as the Horsehead Nebula.

iStar Optical’s Phantom FCL 140-6.5 review

Dec 02 2021 12:01 PM | Psion in User Reviews

From what I was able to see, I conclude that the optics belongs to a Super APO class, which is highly suitable for both visual observing and astrophotography. Unfortunately, I have to state that the TEC 140 lost in the direct side-by-side chromatic aberration comparison test, otherwise the TEC is practically perfect from the optical point of view. The Phantom FCL 140-6.5 is, therefore, a great all-round refractor, and the manufacturer has promised to remedy the minor mechanical issue with the amount of “grip” of the rotary lock. Therefore, iStar Optical can be congratulated on a very well made optical instrument.

Replacing a Damaged Dobsonian Mount

Dec 02 2021 10:39 AM | Oldskaterman in Articles

Considering the choices available for replacing my damaged Sky Watcher Dobsonian mount, I found the same size Apertura mount the easiest and most cost effective solution. In addition to the ease of modifying the Apertura mount, the superior construction and improved azimuth bearings noticeably improved overall satisfaction with this approach.

Nestled in the southeast corner of the dim late-fall/early-winter constellation Fornax, adjacent to the distinctive triangle formed by 6th-magnitude Chi-1 (χ-1), Chi-2 (χ-2), and Chi-3 (χ-3) Fornacis, is an attractive cluster of galaxies known as Abell Galaxy Cluster - Southern Supplement (AGCS) 373.

Fairhavens II

Nov 01 2021 05:55 PM | Gork in Articles

My last article was an overview of Fairhavens, my first dedicated observatory, along with its untimely demise. It is now five years later and I am ready to try again. Being a rental home I could not build a permanent structure (I couldn’t afford one anyway). So, I started looking for a temporary structure that would protect my gear from the elements and still leave room to move about.

Cosmic Challenge: The Southern Pinwheel

Nov 01 2021 05:03 AM | PhilH in Phil Harrington's Cosmic Challenge

Have you ever heard of NGC 300, the Southern Pinwheel Galaxy? Were it positioned high in our autumn sky in a prominent constellation, you certainly would have. In fact, NGC 300, an Sc spiral tilted nearly face-on to our view, would be one of the season's showpieces, especially through large backyard telescopes. Because it lies in the far southern sky, nestled among the faint stars of Sculptor, it remains the purview of diehard deep-sky fanatics only.
