Hochwertiger EnergieschutzfilterHabe mir diesen hochwertigen D-ERF Filter für den Umbau zugelegt. Bringt ein zuverlässiges solides Bild. Keine Geisterbilder etc. . Visuell auch ein Genuss mit DER Sicherheit für die Augen!!!Enrico -
Très utileJ'avais déjà le TZ2 et le TZ4, mais pour utiliser ma caméra Basler 1920/155 au mieux il me fallait un 3x. C'est donc le TZ3 qui m'est très utile. Je l'utilise en observation visuelle et donc en imagerie.JR Roudier -
Test of TZ-3 telecentric systemMy solar instrument consists of the following parts: first a full aperture Baader ERF filter, next a refractor Orion 100/1000, next a blocking filter, next the TZ3 telecentric system, next the central part of Daystar Quark filter (in fact the Ha interferentiel filter), next a diagonal mirror, next a tilter to avoid fringes in the image and to finish ZWO cmos camera. So the total focal is 3000mm, giving a solar image size of about 27mm. The refractor is in parallel with my 300mm Meade SCT on an homemade azimuthal mount. The system can be used in visual too, by removing the camera and place an eyepiece. The first notable thing in visual observation is the contrast of images: it's a lot better than with the previous telecentric barlow included in the Quark. The image is sharp in all the field of view. The Fabry Perrot filter seems to work fine with the quasi-parallel rays comming from the TZ3. With the camera, it’s mandatory to have a tilter, otherwise you have fringes due to interferences. And again the images after processing are very good. It is the first time I am able to get images with such details. To conclude, my TZ-3 telecentric has really improved my sight of the sun, and now if I want to go farther I should buy a very expensive narrow Ha filter, perhaps later. In the next month, I will try the TZ3 on planetary images with my 300mm Meade SCT.Michel M.

Baader TZ3I had been imaging the sun for a long time now but nobody made a telecentric 3x until now. My telescope is a F8 refractor and a 2x would only give me a F16 system while the available 4x would give me a F32 all but useless on most days where the seeing conditions are not perfect. Glad to see that Baader has answered the calls for a good telecentric lens of 3x.Randy

Erfahrungsbericht zu TZ-3 und RG-4 für die SonnenbeobachtungWie schon das Baader TZ-2 - eingesetzt zusammen mit dem TC 0.7fach – ist das neue TZ-3 zusammen mit dem RG TZ 0.4fach ein ausgesprochen variables System für die Sonnenbeobachtung im H-alpha Licht. Es ist über die flexible Brennweitenreduzierung beliebig an Seeinbedingungen anpassbar. Bilder, aufgenommen mit dem TZ-3 zeigen eine enorme Detailfülle, die Bildauflösung liegt bei 110mm Öffnung unter 1 Bogensekunde und die Bilder sind über das komplette Gesichtsfeld „knackscharf“ bis zum Bildfeldrand. Durch die variable Brennweitenreduzierung mit dem RG TC 0.4fach und gegebenenfalls einer zusätzlichen T2 Verlängerung habe ich aktuelle Seeingbedingungen und geforderte Gesichtsfeldgrößen optimal unter Kontrolle. Ein weiterer Vorteil des RG TC 0.4: die Belichtungszeiten der Einzelbilder bei der Aufnahme eines avifiles reduzieren sich dramatisch und auch bei Mosaiken gibt es Zeitersparnissen, allein durch den Umstand, dass weniger Bildsegmente erforderlich sind. Alles in allem für mich eine optimale Lösung, um mein Sonnenteleskop mit einer Öffnung von 110mm betreiben zu können, von daher 5 Sterne für Mechanik und optische Performance des TZ-3/RG TC 0.4fach und noch einmal 5 Sterne für die Firma Baader Planetarium, die immer wieder durch eigene Entwicklungen die Beobachtungsmöglichkeiten der Amateursonnenbeobachtung erweitert und damit bereichert .W.

Fluorite Flatfield Converter (FFC) / 3x-8x
If I use the FFC with an F/4.5 Newtonian (16") will I also need a coma corrector for imaging on a full frame sensor or can I use the FFC on its own.
Answer rated: 0Because of the > 3x focal lenght extention of the FFC, you will most likely see just some rest of coma at the edges of the field. But if you place an coma corrector and an FFC in a row, the image quality will degrade in the whole field. Therefore its better to use only the FFC without coma correctorAnswer by: Baader Web Team (Admin) on Nov 18, 2019 3:28:00 PMRated: 0

Answer rated: 0The Baader BCF is more open in the red part of the spectrum, means all other colours pass the filter plus some more red. This gives "normal" (daylight) photos a pink touch that you can correct in image processingAnswer by: Baader Web Team (Admin) on Nov 18, 2019 8:48:00 AMRated: 0

Baader UFC (Universal Filter Changer)
Will your new upcoming RASA 8 adapter be compatible with 17mm back-focus cameras? Will there be tilt adjustment available for these types of cameras?
Thanks
Answer rated: 0Yes, this latest addition of the UFC-family - the new RASA 8 / S70 UFC-Adapter (#2459136) which will launch on our website very soon - is compatible with 17 mm back-focus cameras such as ATIK Horizon. The UFC allows to change any kind of filter from 1 1/4" up to 50x50 mm square in front of the RASA 8.
The only function, that still might be left to desire, is an easier way to reach the front adjustment hex-screws of the RASA 8. Due to the very short backfocus available, it is somewhat difficult to reach these screws and to "tweak" the star sizes in each corner of the image to absolute perfectness.
So - in order to even reach this goal (exchange filters AND effortlessly adjust the camera tilt), in February latest we will launch a separate product - only produced for the RASA 8: the FCCT (Filter Changer & Camera Tilter). This unit will feature 3D-printed filter sliders and be only able to accept filters in diameters of 31 mm / 36 mm / and 2"(47.4 mm) w/o cell mount. This is a revolution for the RASA 8 since it makes perfect adjustment of all stars in the field a joy. Already now the first imagers are using this solution as prototypes and the results are outstanding, see here: https://www.baader-planetarium.com/en/blog/rasa-8-extreme-images-michael-jaeger-with-ccd-camera-f2-highspeed-filter/Answer by: Baader Web Team (Admin) on Nov 13, 2019 4:00:00 PMAnswer rated: 0The RASA 8" UFC-Adapter is now available:
