Starlight Instruments Feather Touch FTF2015BCR Focuser For visual USE with Paracorr System (SIPS) Coma Corrector

Starlight Instruments has chosen one of the best coma correctors in the world and created something ingenious: a system that guarantees an excellent image in the corners of all Newtonian telescopes from f/3, without having to worry about the correct distances.

The result: SIPS perfectly corrects every Newton from f/3 for all eyepieces, for visual use

A brief guide to installing the SIPS: The SIPS is optimized for the FTF2015BCR 2" Feather Touch and comes fully assembled, you just need the correct base. The integrated coma corrector moves the focal point out 47mm. That's exactly the total length of the SIPS.Therefore no need to calculate a new focus position.The focal length extension of the Paracorr is 1.15x.This just needs to be taken into account when choosing the correct magnification.

By rotating the Paracorr element, you can set exactly the correct distance to the focuser. This only has to be done once and then applies to all eyepieces. The distance depends on the aperture ratio of the Newtonian telescope.

The collimation of the Newtonian telescope: We recommend always adjusting the Newtonian without SIPS. This is easier because the Paracorr has an optical effect due to the extension of the focal length. After adjustment, you can simply re-insert the SIPS. The setting is maintained.

For which telescopes and application areas SIPS is suitable: We recommend the use of fast Dobsonian and Newtonian telescopes. SIPS is intended for visual observation only, not photography. For photography there is the Paracorr with the appropriate adaptations to buy directly.
