Product QuestionsI have a Meade lx850 ACF 14 and a canon 5d mkiii camera , what adapter is required for use with this reducer ?Question by: steve on May 10, 2016 2:50:00 PMYou can use the OP-19392-47C https://www.optcorp.com/op-19392-47c-lepus-camera-adapter-canon-dslr.html. It will attach, but the Lepus cannot correct the full field of the 5D Mk III as that reducer is designed for 4/3 or APS-C cameras.Answer by: Chris Hendren (Admin) on May 10, 2016 6:27:00 PMI have an LX200 ACF 10" telescope and an SBIG ST-8300M camera with 5 position filter wheel and OAG-8300. What adapter do I need to attach the Optec Lepus 0.62x reducer?Question by: Pieter Strauss on Apr 26, 2016 2:07:00 PMThe adapter length is 102.5 - the camera back focus, which in this case is 57.5mm (assuming that you use Baader filters). This would make the adapter length 45mm long. We can have this custom made for you and will just need to know if your OAG ends with a T-thread plate (42mm) or an STL-thread (2.156").Answer by: Chris Hendren (Admin) on Apr 28, 2016 6:13:00 PMWhy type of adapter (if any) would I need to use this focal reducer with a meade lx600 10" and a SBIG xtf-8300?Question by: Keith on Mar 8, 2016 5:59:00 AMThe scope side is easy - use the included 2" adapter (for the larger models that come with a 2" diagonal) or get an OS-ASCT2. On the camera side, we will need to have Optec make an adapter custom for your specific camera configuration with the back focus of 102.5mm - the CCD camera BF and all accessories (like filter wheel and OAG). Please contact us and we can assist you with this.Answer by: Chris Hendren (Admin) on Mar 11, 2016 4:36:00 PMi wanting to replace my old Celestron F6.3 reducer, can i use this Optec Lepus for my setup, ( T3i, C8, celestron OAG, electric focuser JMI)...would i get a little better edge correction (vignette) then the older reducers! ( i mean less Vignette).I use a C11Edge and an SBIG STT-8300m with self guiding filter wheel and Astrodon filters. Would this reducer be appropriate, and if so, what adapter do I need?
RoddQuestion by: Rodd Dryfoos on Sep 6, 2016 4:54:00 AMUnfortunately, no. The Lepus provides 100% illumination over a 22mm image circle and acceptable illumination over a 28mm image circle. This will cover the main 8300 sensor, but you will not get enough light to your guiding CCD in the filter wheel to guide successfully. For this camera, the best reducer is the 0.7x Celestron reducer, which illuminates a full 42mm image circle and will let you guide without an external guidescope.Answer by: Chris Hendren on Sep 6, 2016 9:15:00 AMDoes the Leptus 0.62 reducer work correctly without correcting the image from a 6" or 8" TPO RC?Question by: Chip on Oct 29, 2015 1:23:00 PMUnfortunately, no. Optec told us that the Lepus would only work properly with the RC scopes if you could change the spacing of the primary mirror to the secondary, as it was designed for scopes like the EdgeHD where the primary mirror can be moved. Please contact us if you have questions about reducers for the RC scopes and we will work to find a solution for you.Answer by: Chris Hendren on Oct 29, 2015 4:23:00 PMI understand that Celestron does not make a reducer for the EDGE HD 9.25. Would this reducer be appropriate for the EDGE HD 9.25?Question by: Rick on Apr 3, 2016 10:18:00 PMThe Lepus Reducer is actually a very good fit for the EdgeHD 9.25". Even better, Optec offers a version that includes mechanical adaptation, which will get the Lepus optic as close as possible to the EdgeHD's rear-corrector lens. That version can be found as OP-19410, searching optcorp.com.Answer by: Eric Blackhurst (Admin) on Apr 5, 2016 11:30:00 AM
