Another question. Is there a filter drawer that can be used on ASI2600MC-Pro?
This combination allows it to get cameras like the ASI1600 into focus when you remove the 11mm ring to reduce the back focus to 6,5mm.
Unfortunately the back focus length of the ASI2600 is fixed by 17,5mm which is too long, even for our new FCCT low profile filter changer that
we want to release soon.
Baader UFC S70 / RASA 8" Adapter (Bauhöhe: 1,4 mm)
The latest addition of the UFC-family - the new RASA 8 / S70 UFC-Adapter (#2459136) - is compatible with 13 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/
