  Review of the APM 152 ED serial number 245

  Dec 24 2018 09:42 AM by hfjacinto

  So here are my thoughts. No matter how much you paid for a premium triplet, on most objects the 152MM can keep up with it. If you want to see no false color and need your ego stroked because the scope is not expensive, don't buy the APM. Get a TAK/TEC/AP, you'll feel better about yourself. If you consider the value, this scope is just an excellent buy. It’s like the EON version of the SW150. You get a better focuser/case/sliding dew shield/rings/ and a much prettier scope.

  THE BURGESS 24MM MODIFIED ERFLE & 10MM ULTRAMONO

  Dec 24 2018 09:04 AM by wapaolini

  The Burgess 24mm Modified Erfle and 10mm Ultra Monocentric eyepieces are relatively new offerings from Burgess Optical. The Ultra Monocentric has been long promised so nice to see it finally coming to fruition.

  APM 140mm DOUBLET APO REFRACTOR

  Sep 10 2018 05:44 AM by Larry Carlino

  Some two dozen observing sessions and direct comparisons with instruments of known quality have convinced me that this APM 140ED is indeed an excellent telescope. It is well built, nicely finished, and it boasts very fine optical quality. In addition, its relatively light weight and short tube length allows the effective use of a mid-size equatorial or alt-azimuth mount. It has almost the punch of a 6-inch refractor in a package that is clearly more portable.

  Comparison of the Boltwood II and Sky Alert Cloud Sensors

  Jun 09 2018 03:42 AM by theastroimager

  This review is a side-by-side comparison of the Boltwood II Cloud Sensor from Diffraction Limited/Cynagon , and the SkyAlert Cloud Sensor from Interactive Astronomy. Both units were purchased new by the author. The sellers were not made aware that I would be doing a review of their products, so no temptation was held to send me anything other than a typical unit.

  Chile Dilly!

  May 05 2018 07:14 AM by astrodoc71

  I would highly recommend this site for anyone who wants to image targets that can only be seen or optimally seen in the Southern Hemisphere. The cost is not prohibitive and the fast optical system makes it possible to obtain enough quality data in a reasonable time frame. The seeing at this site in Chile is excellent, and the resolution and image quality obtained make it well worth the expense, not to mention the excitement of seeing these amazing objects which we cannot see from Northern lattitudes! The user interface is very simple and customer service is superb. While you will have to throw out some subs like we all do at times, these will not come at additional cost. Best of all…they add 20% to your initial deposit if you are a CN member!

  MONO & BINO VIEWING WITH THE BAADER MORPHEUS 17.5MM EYEPIECE

  Mar 22 2018 08:24 AM by wapaolini

  Baader markets their Morpheus line as “high-end” 76° apparent field of view (AFOV) eyepieces designed for visual / photo / video functions that can exploit the capabilities of the finest telescope optics. The eyepieces have a optical design that utilizes 8 lenses in 3 groups and includes the use of 3 low dispersion ED elements and 1 Lanthanum element. With the introduction of the 17.5mm, there are now six eyepieces in the line including 14mm, 12mm, 9mm, 6.5mm, and 4.5mm. All eyepieces can be used in either 1.25” or 2” focusers without adapters. The Morpheus line touts a rather long list of features and comes packaged with multiple accessories.

  The Eye of the Flak (Das Auge der Flak)

  Dec 07 2017 11:46 AM by Micah

  It is a rare and wondrous thing when your hobby and passion leads you to a place where you find yourself driven to pursue discover ever deepening levels of historical and technical detail of a subject and it leads to newer discoveries. It's even more satisfying sometimes when you even uncover information once thought to be lost forever to the ravages of time and a world war. A new publication, "The Eye of the Flak" by Dr. Peter DeLaet and Francis Vermeire, is just that.

  COMPARING THE MASUYAMA 25MM 52°, 25MM 65°, AND 26MM 85°

  Nov 24 2017 06:39 AM by wapaolini

  The modern incarnation of the Masuyama eyepieces seems to have carried forward their excellent reputation for providing high apparent contrast views. Indeed, for the globulars and nebula observed the Masuyama 85° quickly became my favorite during the testing, showing them brightly, richer in details than the other eyepieces, and with the largest contextual TFOV.

  BRESSER 4 Inch f 4.5 AR 102XS Refractor visual observers’ REVIEW

  Nov 24 2017 06:41 AM by TimVerst

  For me, the 102SX is a solid, wide/rich-field travel scope. I’ll pimp up the finder-scope and dew shield, making this one a keeper.

  New Moon Telescopes 16”f/4

  Nov 24 2017 06:44 AM by kreegan99

  After purchasing my New Moon Telescopes 16” Dob, the amount of observing hours I logged doubled easily. The scope performance is superb, but making it easy to setup, roll out, collimate, etc really makes the big difference in my very busy life.

  The Ages of Astrophotography 1839-2015

  May 06 2017 04:51 AM by RefractorPhill

  The author, Stefan Hughes, is a historian/ astronomer with a passion for astrophotography and genealogy (family tree research). His interest for ancestral research and the lineage of families gave rise to his first book "Catchers of the Light - The Forgotten Lives of the Men and Women who First Photographed the Heavens" in which he focuses on the background of the first astro photographers and astronomers 19th and 20th centuries. The second book, "The Ages of Astrophotography" is a must-read sequel which fits well on every astronomer's book shelf!

  Stardust Gallery LED Lightbox and Metallic Print Review

  Feb 25 2017 08:47 AM by ctron

  The owner of Stardust Gallery, Craig, was looking for volunteers to review an LED backlit lightbox containing either a Hubble image or an image of user choice. Since I had what I felt were fairly decent Milky Way images acquired from a session at a dark sky site late last Fall, I thought one of the somewhat processed images might be a good candidate to display inside one of the Stardust Gallery backlit lightboxes, and eagerly forwarded the image to the website.
