About this deal

The problem is that the focus point of a cross hair eyepiece is often different to that of a standard 1.25" eyepiece. Now, during the global pandemic, when everyone wears a face mask, the online mirror can help you a lot. In situations where you do not have a real mirror, the online mirror helps you to properly arrange the protective mask, carefully covering your mouth and nose. Use our online mirror, arrange your face mask, to be comfortable, but at the same time to be fixed correctly. Wear a protective mask correctly and be healthy!

Javier Moreno about his product: "A mirror fulfils its function, but I wanted to create a mirror with more to offer than that. Usually, the last glimpse of everyone before leaving the house is the one in the mirror. So why don't dropping all the small necessary things we need before we leave the house there?" Please note that the upper port is restricted by the T-2-thread and the diameter of the diagonal. The usable field is 32mm, equal to our 32mm T-2 prism diagonals.

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). I am not sure, if the 120mm achro could be focal reduced down to f/2.5-f/3. Chromatic aberration of refracting optics is getting worse with more bending of the light. And f/2.5-f/3 requires a LOT of bending. Also, you needed to cut a LOT from all tubes. A 120mm f/2.5 refractor is about 1 foot long. On an astronomical (CCD) camera, the sensor is closer to the connection thread than on a DSLR – if it is closer to the FlipMirror than the 29mm of the eyepiece clamp on upper port , you may need to insert a T-2 extension in front of the camera. At Rother Valley Optics, one thing we pride ourselves on is customer service and quality of our equipment. When we test your telescope, we will ensure that it is of the highest quality otherwise, we will reject the scope under our strict quality control and test another model for your peace of mind. One of the main values to look at when testing a refractor is the Strehl ratio. The higher this number, the higher quality lens you have. At Rother Valley Optics, we will guarantee the highest possible Strehl ratio for your telescope. We will aim to provide 0.95 Strehl or higher on Takahashi, RVO Horizon, William Optics and many more! Generally, the higher the Strehl ratio, the lower the Astigmatism and Coma meaning a better image quality from your instrument. Our video flipper lets users set the preferred file format. It can be MP4, MOV, MKV. This way, you can use this tool not only to mirror videos but also to convert your files into different formats.

We'd recommend to use these two clamps and to determine the focus position of the eyepiece. You shouldn't need to insert it completely into upper port, as that clamp is shorter. If desired, you can add T-2-extensions later to get to the right distance. Or you focus your telescope now with the cameras to find out how much the focus differs between eyepiece and cameras, then you can determine the required T-2-extensions in advance. Yes, you can, providing you find a readily visible object first, aim at it and make sure your EP is parfocal with the camera's sensor. It may require 1- moving the EP in or out of its tube, 2-adding or removing the extension tube(s) to the camera port before mounting the camera to the flip mirror, or 3-choosing a different EP. Do a test shot with any of these to determine the EP and camera are parfocal, unless your larger monitor is clear enough to confirm focus. Then you can find that dim object. I could not add pictures to the intended reply. So I created a new review with a 5 star rating due to the applied improvement. Thank you for digging up the old thread about the flip mirror. Since then I have switched to using a Lodestar, that has a larger sensor than what the LN300 had. Correspondingly, I also modified my setup and reduction factor. I still have the same flip mirror with the Meade 0.63x reducer but on the camera I now have only a 0.7x reducer. This change was needed due to the larger 9mm diameter sensor of the Lodestar. (As opposed to the 6mm diameter sensor of the LN300.) The original more aggressive setup would strongly vignette the larger sensor and also cause ugly distortions in the outer regions of the field. The distances vary, depending on nosepiece and focus of the guiding camera – it may as well work without a 1.25"-extension.Alternatively, we would gain a little more leeway and make do with an extension sleeve if we put a golden 1mm T-2 spacer instead of the 7.5mm sleeve in front of the camera - but we want to show as many options as possible here. Am Anfang (aus der Ferne) machte ich mir Gedanken über die Orthogonalität des Klappspiegels, dessen Fassung, Drehlagerung und vorallem über die Verwindungssteifheit des gesamten Gehäuses. Denn daran sollten eine SBIG STF-8300M, eine kleine Guidingcam Alccd-QHY 5III 174 und ein Okular platz finden. Ein beachtliches Gewicht für so einen kleinen "Würfel". Meine Bedenken haben sich nach einigen Nächten praktischen Einsatzes in Luft aufgelöst. Bis auf eine kleine Sache, was die Adaption des Off Axis Guider für Baader FlipMirror II (BFM-OAG)
