A customer review of the 17 inch PlaneWave AstrographDear Mr. Baader, I am happy to comply with your request and share with you my criteria that led to the purchase of the 17 inch telescope from Planewave, and following my experience with this telescope. Since this was a rather complex topic, please forgive the long text and its extent, which certainly clearly exceeds a "normal" customer judgment. Decision criterions for the choice of the Planewave astrograph were primarily: - robust mechanical construction of the whole telescope, - fixed installation and collimation of primary mirror and field corrector at factory, - stable secondary mirrorcell, - easy adjustment of the secondary mirror, - easy control of distance between the main and secondary mirror withRonchi test, - good focus stability with slight temperature differences, - affordable focal reducer available, - a price difference of about 10.000 Euro to a RC telescope from renowned European or international manufacters. To the last point, my following remark: I have not looked into the RC telecopes offered on the amateur market, which are delivered at 16 inches opening and a price below 10,000 euros. Production at this selling price - especially for an RC system - was unimaginable to me. In addition, it is hard to find any reference images taken with these instruments on the Internet, in comparison European - made RCs and PlaneWave telescopes have many international references. Does that Setup have any disadvantages? Little after almost 4 years of operation: - the 17" Planewave has an open tube in comparsion to the 12.5 inch and the black "Spantex" cloth against scattering light is often "willing" and shifts easily above the main mirror that is quickly partially obstructed. - main disadvantage is in my eyes the very short focus travel of the 3.5" electrical Hendrick focuser of just 32mm, but otherwise it works very decently. I have sent the entire report to Baader Planetarium.W. Paech

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.Is Answered? Yes (1 answer)
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: 011/17/2019 8:53 PM BCF 2 Astro Conversion Filter CANON EOS 5D/6D MK II
If I modify my dslr with a baader bcf filter inside the sensor, the photos after modification will be only red without any blue or green?Or just more red plus blue and green as before?Is Answered? Yes (1 answer)
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: 011/12/2019 1:20 AM 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?
ThanksIs Answered? Yes (2 answers)
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:
