This past year, we have made some upgrades to the Illig system - primarily the Nitecrawler rotator+focuser and mount maintenance. To further capitalize on these foundational upgrades would be to next take a look at the imaging system to increase the flexibility of the system and to take advantage of recent CMOS sensor developments.
An upgraded imaging system should allow for flexibility in both the individual imaging project and public outreach realms. No single system can accommodate both with perfection, but I think it is possible to get close and allow the Illig system to cover a fair range of interests and object types.
To recap the current Illig configuration, it is a Takahashi TOA-150 triplet refractor, with a native focal length of 1050mm at f/7. It is fitted with a Takahashi 67 1.0x field flattener. This combination creates a corrected field that is circa 92mm in diameter, 106.2mm in back of the flattener. This means we have a 106.2mm gap to fill with equipment between the flattener and where the c
