How We Removed Sensor Tilt on Our New RASA 11 Telescope (Hint: Octopi-Astro Camera Interfaces Rock)

Emerald Hills Skies shares the night sky via live sessions of electronically-assisted astronomy (EAA) featuring Doug Lucas, President of Team Expansion, at Team Expansion's 61-acre campus, Emerald Hills, on the outskirts of Louisville, Kentucky. Occasionally, we also share "Skylets," which are more focused on the "craft" of EAA and astronomy in general. In this Skylet, we offer one solution for removing sensor tilt from a Rowe-Ackermann Schmidt Astrograph (RASA) 11-inch scope. A RASA telescope is like a race car: It has "ultra-fast" optics. But great power can also signal great complexity - and it does so in this case. It has a VERY narrow critical focus zone (CFZ otherwise known, in the still photography world, as "depth of field). In this video, we tackle the challenge of removing the aberrations that can show up in the corners of our images if the RASA's sensor is (even slightly) "tilted" -- if it's not aligned properly with the imaging train. We also examine, review, and field test a brand new product being developed to address these issues. The company behind this dream is Octopi-Astro. Watch this video to see whether or not the Octopi-Astro camera holder will help RASA 11 owners fix tilt, once and for all! During the one-hour video, we help users understand the process they'll have to go through to begin using the brand new, super-beefy Octopi-Astro camera holder. To our knowledge, there is no other video like this which helps a RASA 11 owner understand the workflow of dealing with tilt of the camera sensor. Seeing it demonstrated in a video will, we trust, help end-users immensely because they'll then be able to apply this demonstration and thereby save multiple hours of research and trial-and-error for developing that process. During this video, we use CCD Inspector. CCD Inspector isn't free. But it provides a fast workflow to act as a guideline for evaluating field curvature (often caused by incorrect backfocus) and sensor tilt, both of which introduce star shape aberrations in the corners of our images.

They did invite me to beta-test their camera interface and, in the process, shipped me a prototype unit containing a new filter holder. I approached this filter holder without bias, however, since they placed absolutely no conditions on the use of this prototype. This review is, then, completely objective and unbiased.
