  A Backyard Observatory For Under $500?

  Nov 15 2020 10:33 AM by Gork

  Back in my days as a Quality/Reliability Engineer, we had a motto by which we lived; “Good, cheap, easy……Pick any two”. For this project I chose cheap and easy. I would keep my computer, cameras, and accessories in my den when not in use, and the mount and telescope could stay, semi-permanently situated outside. The search began. Who in the world makes a portable or temporary structure large enough to provide security for a 10” f/4 newtonian riding on a Celestron CGX mount?

  Musings over Mars

  Nov 15 2020 10:22 AM by TimVerst

  Braved the first frosty forecast of the season Tuesday evening GMT for a couple of hours at the eyepiece under clear South London skies to have a go at sketching the Red Planet before the distance becomes too great.

  Photoelectric Photometry of Variable Stars - Past and Present

  Nov 15 2020 09:14 AM by Rustler46

  Someone on the Classic Telescopes forum asked me (see reply #3750) to share what I called "another story" of my experience with photoelectric photometry (PEP) of variable stars. I hope this article will encourage others to make such contributions to scientific studies of variable stars. So what follows will largely be what I remember about my experience as a photoelectric photometrist back 1985-90. Many of the concepts and techniques are still valid today. You'll find technology has improved greatly since 1990.

  Review of the Hubble Optics 14 inch, f/4.6 Premium Ultra Light Dobsonian Telescope

  Sep 29 2020 05:35 PM by Chris Westland

  I looked at HO telescopes for some time before purchasing mine. On paper, the design is elegant, and takes advantage of the 6063-T6 aluminum alloy used in all of the telescope’s components. The sandwich mirror is innovative. The upper cage looks more rigid than a flat ring, but without being too heavy. In general the HO telescopes are unique and affordable. I am a previous owner of an Obsession Classic 20", and Dave Kriege’s scope set a standard for what I was expecting from a Dobsonian telescope.

  I wanted to provide a review of my experience with a Starizona Landing Pad I recently purchased for my CPC 1100.

  I would highly recommend this battery for your portable equipment, I am convinced.

  Nexus II Review

  Aug 29 2020 03:54 PM by xrayvizhen

  SUMMARY: The Nexus II is an outstanding piece of equipment that allows anyone to use their Smartphone or tablet and see where their telescope is precisely pointed. It is an extremely cost effective and easy way for someone to add digital setting circles and a “Push-To” function to just about any telescope.

  New Moon Telescopes 20”F/3.3 Review

  Aug 23 2020 05:37 PM by ilan_shapira

  This instrument answers to all my requirements from a big dob and is mostly used during my dark site trips. While double stars and planets are not the specialty of this scope, it handles them fairly well, but requires extra good conditions - backyard usage is not optimal as atmospheric disturbances dramatically affect the views. DSOs is where this instrument excels and provides the best performance under dark skies, especially with faint galaxies. During my last dark site session, after the COVID-19 restrictions lifted, I had barely time to observe myself as others lined up to view instead.

  FIELD TEST OF THE BAADER MAXBRIGHT® II BINOVIEWER

  May 09 2020 06:38 PM by wapaolini

  Overall, using the MaxBright II Binovewer has been a transformative experience for me. I have been binoviewing with my telescopes for well over a decade, but the experience has never been what I would call a pleasant one due to the myriad of quirks I find when using the William Optics Binoviewers. However, with the MaxBright II Binoviewer all the issues I previously encountered are now fully resolved, making my experience binoviewing for the first time entirely enjoyable.

  My Experience using SkyWatch for the Alphea All Sky Camera from Alcor Systems

  Mar 05 2020 01:17 PM by TeslaTrek

  The Alphea 6CL AllSky Camera is a well-made ruggedized outdoor color camera with equally ruggedized connectors. There is no bubble level to aid vertical alignment. The Alphea camera is very expensive given the accompanying SkyWatch software is not reliable and the user interface not well thought out. The software has the feel of an explorative research project into what can be done with an AllSkyCam. The overall slow performance is unimpressive. I discovered many bugs and quirks. It includes many features, which are not well documented. This along with almost non-existent user support makes for an expensive and frustrating AllSky Camera experience. Given the present state of the software, the user might want to consider AllSkyEye. In summary, given all the issues I found with SkyWatch, I would still look forward to a significant software update because SkyWatch does show much promise.

  My experience using two 80-millimeter long-focus refractors

  Dec 13 2019 08:26 PM by caussade

  The Orion and TMB refracting telescopes are both a joy to use, and will undoubtedly stay with me for life. I sometimes get offers to sell but have politely declined; as the reader will suspect, the thought of a sale has never entered my mind.

  GSO 8-inch TRUE CASSEGRAIN

  Dec 13 2019 07:43 PM by Larry Carlino

  GSO Cass can be regarded as somewhat of a specialist instrument. Its excellent overall optical quality, fine lunar and planetary performance, reasonable size and weight, and bargain price make it a fine choice where sterling deep-sky and rich-field capability are not a priority. It is a good alternative to much pricier 5 to 6-inch apochromatic refractors for both visual and ccd work. In the price- to- performance ratio, I don't see anything in its price range that comes close (except, perhaps for a high-quality long-focus Newtonian [but try to find one!]) as a dedicated lunar and planetary instrument.

  Celestron Regal 65ED M2

  Oct 16 2019 09:17 PM by Riccardo_italy

  There is at the moment a heated discussion on Cloudynights about spotting scopes. I can only confirm my initial impressions: for a dual day&night scope, a good quality spotting scope is, IMHO, a very good choice. The scope performs nicely also for astronomy, and not only for daytime use. I do not agree with people that says a spotting scope cannot be used for astronomy.

  Review: The Vixen FL55ss

  Sep 08 2019 04:31 PM by Hesiod

  Overall judge the FL55ss a good product. As a wide field astrograph is very proficient and easy to use, so would suggest it wholeheartedly, even to beginners (usually at this stages apreture does not matter, while the clever Vixen mini-refractor is very user-friendly and, at 300mm, gives a more forgiving sampling than the popular 60-80mm rebranded models).
