I was recently contacted by Optolong, a filter manufacture in China who asked me to test their filters. They sent me a set of 36mm un mounted LRGB and a set of 36mm Narrowband Filters, H-Alpha 7nm, OIII and SII 12nm. I was impressed when they arrived, nice packaging and presentation in a similar plastic case to the Baader.
About a year ago I decided to get back into astronomy after a 7 year hiatus. I live in the Portland OR metro area, where the weather can be astronomically gloomy for long stretches of time. Previously I had concentrated primarily on Astrophotography (published in Sky & Tel and Astronomy magazines), and have owned a wide variety of scopes and mounts
Morpheus, in Greek mythology known as the god of dreams, and now the new Baader Planetarium entry in the field of high-performance wide fields. In field tests, Morpheus eyepieces proved themselves to be a very sizable step up in both performance and ergonomics compared to the older Hyperion line.
Anyone who reads Jim Chung’s book will want to have a look at their existing astronomy gear and wonder what they can do to make their hobby better. The book shows how any amateur astronomer can modify or make astronomy gear from readily available parts, or by recycling parts while being mindful of costs. The broad spectrum of subject matter is written well and detailed, and balances nicely with the right amount of material and illustrations.
Overall I am extremely pleased with the performance of the ASTF. It exceeded my expectations and provided a white light solar view that was brighter and more detailed than the standard full aperture glass filter I have could provide.
The AT111EDT is a doubly haunted scope. Haunted by the tragic, premature death of the illustrious designer of its optical group, and haunted also by the turbulent financial times into which it was born. Will there be another run of this fabulous instrument? I certainly hope so, but telescopes are a tough business, and the landscape of the refractor market in particular changes quickly.
How much do I love my NexStar 5? It could be the best scope I have ever owned. The SCT 5" in my opinion is the size of scope that gives good Planetary views, and DSO's start to be able to be studied in detail. It is also a nice non pain in the back weight wise.
