In order to use the OAG port at the base of the flip mirror, the prism can only go so high before it will hit the mirror when ‘down’. If your connection to the telescope relied on a 1.25” nosepiece rather than a 2” / T2 /M48 connection, would the light ever reach the prism as it would be too low to pick up any light?

I cannot get the image in the eyepiece to center. I'm using the Baader Focusing Eyepiece holder. I have moved the adjustable T2 ring to its limit, but the image when centered in the camera is at the edge of the field of the eyepiece. Ideas?

I would like to use your "flip mirror" as a ligth sources selector with my leitz microscope (LED cool ligth or halogen one); to do this I would like to replace the adapter rings with Leitz ones on two sides of the unit; the third one will be used for straigth connection to microscope inlet (by a locked coupling ring).
Do you think it is feasible? may you send me a tech drawing with ring holes on the three sides?
I thank you in advance for your kind answer.
Best regards

I have a Meade LX90 with the Peterson Eyeopener 2” conversation. This allows a 2”diagonal or lens to be inserted.
I also have a DSLR with the T2 adapter for Astro photography. Can you tell me specifically what additional adapters i will need to connect the flip mirror to the 2” opening on the Meade and to allow 2” eyepiece plus the DSLR?

Baader FlipMirror II Star Diagonal
Various ports – variable work
Telescope auxillary instruments cover a wide range of interests, from a sole eyepiece, via camera use, to high end spectroscopy. Unfortunately every telescope just features one exit port. This causes relentless manual exchange of parts in the dark, causing huge time loss, wear on the parts - and "nerves". And whenever you start controlling your telescope remotely - the single port becomes a painful reality.
Improving workflow, especially during astrophotography is the goal set out for the BFM II. This is not just a simple flip mirror but much more, as there are three ports to be put into action.
BFM II makes your single telescope port variable - to suit your various interests.
The FlipMirror II Star Diagonal allows a variety of permanent adaptations to your telescope 1 . Use the rotary knob 2 to switch between the rear port 3 and the top port 4; you can use an optional toothed belt to operate it with a motor (not included). An autoguider or a calibration lamp can be connected to the bottom port 5.
General Function of the FlipMirror II Star Diagonal
The BFM II lets you switch between a straight light path (Position A) for a camera or other measuring instruments and an angled light path (Position B), e.g.
for an eyepiece. The following figure shows how it works. In addition, a calibration lamp for spectrographs or an Off-Axis-Guider pickoff-prism (that is not affected by the mirror position) can be connected at the AUX-port on the bottom

Mars Opposition 2020 –The Return of the Red Planet
Do you still remember the lunar eclipse two years ago? At that time the moon was not the only orange-reddish celestial object. Nearby – next to Jupiter – there was Mars in the sky, too. For many people, this was the first time they saw the two planets knowingly "live" – thanks to the attention that the lunar eclipse generated. Unfortunately, the Moon will not give us such a show again this year, but Mars is coming back. As since the beginning of mankind, it can be seen brightly shining in the sky every two years. That's because two Earth years are almost exactly as long as one Mars year, i.e. the time Mars needs for one orbit around the Sun. Only then will it shine again as a bright "star" in our night sky. THE WARRIOR IN THE SKY, OUR FUTURE HOME? What impression did a biennial, particularly bright, orange-reddish celestial body, which returns every two years, make on our ancestors? 5,000 or even 10,000 years ago, when humans did not yet live in light-flooded cities that outshine the starry sky, Mars must have been very striking. Every culture has located its gods in the sky and seen their...

The telescope equipment for the Mars Opposition
Tips for the visual observation of the Mars opposition 2020 The observations of the Mars channels in the 19th century were made with telescope apertures of 30 to 50 centimeters. Telescopes with similarly large apertures (like the Celestron C14, or the PlaneWave CDK 12.5- and 20 inch) are now well within the reach of amateur astronomers. Perhaps you will succeed in spotting the large Canyon Valles Marineris? To help you succeed in the hunt for fine details on the Red Planet, we have put together some tips for you. Telescope and accessories: In order to adjust the optics to the outdoor temperatures, bring your telescope outside sufficiently long before the start of the observation to minimize instrumental seeing. At the beginning of October the temperatures around midnight can be quite cool. If your telescope is located in a dome or a retractable roof hut, open it in time. If you use reflectors for observing Mars, make sure that the optical system is collimated as perfectly as possible. That the telescope optics should be as clean and dust-free as possible, especially the Schmidt plate f SC telescopes, applies to all kinds of visual observations. Also make sure that the eye lenses...

Overview and Recommended Use: Baader Star Diagonals
The most versatile tools: Baader Star Diagonals (T-2 and 2") Manual and Recommended Use A Baader star diagonal (both prisms and mirrors) can show you impressive images for a lifetime and offers more connection and configuration options than standard star diagonals. Baader Planetarium's star diagonals not only offer the highest mechanical and optical quality, but also have the additional advantage of being part of a large, modular system. They enable very short adaptations as well as threads for direct connections to a telescope or a Baader focuser, as well as adaptation to a wide range of threads for torsion-free use with heavy or long accessories, such as binoviewers. Decades of customer feedback led Baader Planetarium to create a seemingly overwhelming amount of adapters. But each adapter has its purpose. This is the reason why you can always find the optical length of each part in the product description, so that you can find the best solution for your needs. To get the most out of them, we recommend that you spend a few minutes reading this brochure. On the following pages you will find a guide on how to choose coating and star diagonal type an overview of the different...

Baader-UFC (Universal Filter Changer) – the ever-growing filter chamber (Part 1)
The Baader Universal Filter Changer (or UFC for short) is a very versatile simple system for using, mounting and changing (or swapping) filters in and out of a light path. The UFC can be used for imaging where you may want to swap different filters (e.g. LRGB) between a camera and a telescope but do not want the bulk, or expense, of a filter wheel. The UFC can be used between a camera and a Celestron RASA 11/14(36) or a Starizona Hyperstar system where the overall size and shape of a filterwheel causes issues. You can also use the UFC for visual purposes where you can easily switch between different colour filters between a telescope and an eyepiece. The image below shows the standard "exploded" diagram of the parts that make up the Baader UFC. We've colour-coded it to highlight the main different parts (see below). At present there are 30+ parts to the whole UFC system in total. The large number of components may seem somewhat overwhelming at first glance, and can lead to some confusion, and that the system is complicated. However, we hope this series of blogs will help show how simple, and effective, the UFC is....

The Baader Astro T-2 System™
For over 30 years we have focused on the Astro T-2 thread system (M 42 x 0.75 mm); virtually every telescope manufacturer must offer this thread far ahead of the focal point of his instrument, such a universal T-ring (for DSLR cameras) can be connected. The only exceptions are (still) Russian equipment, there the thread diameter is the same, but the pitch is still 1mm per revolution - rather than 0.75mm! Therefore, we offer among other things a "Russians adapter". At only 7mm additional optical length it can allow so many Russian lenses or telescopes to be compatible with an international Astro T-2 (M 42 x 0.75mm) connector! For the sake of better recognition mostly are marked. See marking small 'a' or small 'i' in the respective indication! "a"; identifies an external thread (male); or, if Ø sign which a diameter, "i"; - a female is always (female) or - Ø character - an inner diameter. The Optical Length The optical length describes the extension of the optical path caused by an adapter or accessory when inserted into the beam path of the telescope. The values listed in the system table rounded to 1/2 mm. For pure threaded adapters...
