Off-axis guider for 3” and 4” Wynne.
This is an OAG for 3” and 4” Wynne correctors where the CCD adaptor is replaced by a new system which contains a prism and allows connection to the CCD camera of choice. The example shows an image of an FLI 8300 camera plus a CFW 7 filter wheel. It may be necessary to send the parts to Starworks to ensure accurate realisation of the OAG. We suggest the use of compact guide cameras such as the Starlight Lodestar or the SBIG ST-i. Available on order.

OAG for the Takahashi BRC-250 which substitutes the original TKP 80100 and TKA 27113 with an entirely new support system for the prism and the CCD autoguider. Placed directly behind the corrector to better utilise the corrected field. Available on order.
Off-axis guider for the Canon DSLR
Custom off-axis guider
We can produce custom OAGs for your own specific needs, minimizing the space and the number of adaptors required. On the side is an example of an OAG for a SH-9 ccd with a filter wheel and a Baader MPCC. Contact us for more information. Available on order.Adaptors for Coronado filters
.

Cells for Baader ERF solar filters
We produce ERF filters for application at the rear of the instrument, with the possibility of inserting a Baader diaphragm to vary the aperture. Contact us for more information. Available on order.Custom-made adaptors
Customizing the optical train is often the only solution for optimising the performance of the instrument. By so doing it is possible to substitute superfluous adaptors and extenders which compromise rigidity. All work is done on lathes and CNC mills, contact us for more information.

Primary mirror lock
Primary mirror locking system for Meade and Celestron SC telescopes. Consists of a plastic ring attached to the primary mirror on which three shafts allow external locking. Once the correct back focus is achieved, the mirror can be locked reducing mirror flop to zero. Requires drilling the rear support and an external, secondary focuser. Contact us for more information. Available on order.
