In just under a month, an annular Solar eclipse will take place on the morning of Thursday June 10th. An annular eclipse occurs when the Moon passes between the Earth and the Sun but the Moon's apparent diameter is smaller than that of the Sun's due to the Moon's orbit being elliptical and it being further away from our Earth (at/near apogee) at that time. This leads to the outer parts of the Solar disc being "exposed" in an annulus or ring - often called "ring of fire".
For those lucky enough to live in north-east Canada, western Greenland and far eastern Russia, will get to see the annular phase event which will last for a maximum of 3m 51s over north west Greenland. For...

Cooled CMOS imaging cameras for astronomical use have come a long way over the last few years and they are here to stay. The
QHY268M PH, BSI Cooled Medium Size APS-C Camera (Photo) (#1931096, € 2775,-)
camera has been hotly anticipated and has become a focus for a lot of astrophotographers for its high specifications, build and image quality.
The QHY268M is a monochrome cooled CMOS camera that utilises a very sensitive APS-C sized Sony IMX571 sensor. Typical of other QHYCCD camera bodies, the 268M features a matt black cylindrical design with, in this case, a red colored band around the body at the sensor end with QHYCCD’s name and logo and the camera model – QHY268 – clearly labelled. The body is 90mm in...

Instruction Manual: Baader FlipMirror II Star Diagonal
Using the Baader FlipMirror II Star Diagonal (BFM II) at the Telescope
Baader FlipMirror II Star Diagonal (#2458055, € 195,-)
is not only an accessory for professional users, but much more: It is a helpful tool for every amateur astronomer – especially for astrophotography.
First of all, the BFM II is designed to completely replace your standard star diagonal, so that you can keep observing as usual, just like with every good star diagonal. But the BFM II gives you much more options. You can create – from the beginnig, or step-by-step – your own system for photography and keep it always ready-for-use at your telescope. This will save you a lot of time and nerves. In...

The CGX: A Versatile Mount For Everyone!
Recently I was able to work with the Celestron CGX, the Baader Apo 95/560 Travel Companion, the Nikon D810A and the StarAid Revolution as guiding system for the first time. Once again the results proved how much you can get out of a good system if you take some time to tweak the settings a little bit instead of simply working with the factory settings of the software without taking a closer look at them.
To get straight to the point: I'm really excited about what the CGX delivered last night!
For polar alignment, I used the star Regulus and the integrated AllStar Polar Alignment (ASPA) system of the CGX. My alignment routine only consisted of a 2-star alignment, with...

WHY are the QHY600 monochrome CMOS cameras more expensive than models from other manufacturers that also use the Sony IMX 455 BSI CMOS sensor?
The image sensor - the heart of EVERY astronomical CMOS camera
Image sensors are THE basis of ALL imaging in astronomical photography. The performance of the camera - i.e. the read out raw image after exposure - is based on the quality of the CMOS or CCD sensor and its performance.
Image sensors of many manufacturers are produced in different qualities: In very high quantities the "consumer-grade" sensors and in much lower quantities - and therefore much more expensive - the "industry-grade" sensors, which have to pass more extensive and tougher quality controls before delivery.
QHYCCD is one of the few...

Our customer Jörg Schoppmeyer sent us this unusual picture: a circular Mercury, shortly after the upper conjunction and only 1.8° away from the Sun!
Mercury is traditionally a difficult object to observe. The reason: The small planet is always close to the Sun and can be seen with the naked eye only shortly after sunset or before sunrise when it is at maximum distance from the Sun. Legend has it that even the great astronomer Johannes Kepler never saw Mercury with his own eye - but Kepler did not have a modern telescope with accessories from Baader Planetarium...
On August 18th, 2020, Jörg Schoppmeyer pointed his
BAADER APO 95/580 CaF2 Travel Companion (#2300095, € 3850,-)
at Mercury. Since the small planet was only...

We received a question from our customer about our turn-key telescope solutions. It was actually only a short question, but we answer it in detail to show you what kind of benefit it provides, when ordering a complete telescope system from us.
Could you tell me what the OTA rings on the TEC140 in the attached image (from a Baader installation) are. I can see that the outer rings are the Baader heavy duty rings but what out the inner rings (inside the larger, outer rings). Do you sell these inner rings?
In short: Unfortunately we cannot offer these as regular purchasable products.
In detail: these inner rings are always specially made for each complete telescope project where we supply all instrumentation...

Ich sehe an hellen Objekten Spikes – ist mein Prisma defekt?
Concerning Amici prisms, there are two factors which can limit the use for astronomy. The first one is the optical quality, i.e. how good is the alignment of the optical surfaces. Most Amicis are made for terrestrial use, where our atmosphere limits the useable magnification to ca. 60x or 70x, anyway. So, it's fine if they don't show a double image up to ca. 100x, as such high magnifications can't be used.
Those prisms which are designed for astronomical use are designed for those magnifications which we can use for the night sky – ca. 300x or even more. This high precision makes our Astro-Amici star diagonals so expensive.
But all Amici-prisms – no...

William "Bill" Paolini has been actively involved in optics and amateur astronomy for more than 50 years, and is author of the popular book: : Choosing and Using Astronomical Eyepieces
We appreciate the positive feedback we have received so far. The Baader MaxBright® II Binocular with case (#2456460, € 425,-) incorporates the knowledge aquired during thirty years of building astronomical binoviewers. It closes the gap between cheaper entry-level binoviewers and our high-end Mark V Giant Bino – see also the article about the differences between MaxBright® II and Mark V Großfeld (Giant) binocular.
A detailed test report: Field Test of the Baader MaxBright® II Binoviewer has now been published by William Paolini in the most popular astro forums. We are very happy about his extremely...
