What is the purpose of the Starlight Instruments SIPS Housing?
This housing allows an astronomer who owns one Starlight Integrated Paracorr System (SIPS) to use its optical element on a second or third telescope. By installing a housing on each scope, you can quickly move the expensive corrector optics between them without buying a complete SIPS unit for each instrument.
Which focuser is compatible with this SIPS Housing?
This housing is specifically designed for use with a 2" Feather Touch focuser that has 1.5" of draw tube travel. It is not compatible with other focuser models or draw tube lengths.
Do I need to buy new optics for this SIPS Housing?
No, this product is the housing only. It is intended for users who already own a complete SIPS unit and want to use its existing optical element (the Tele Vue Paracorr Type 2 corrector) in another telescope.
Will I need to "re-tune" my SIPS optics every time I move them?
No. The housing is precision-machined to maintain the exact optical spacing required by the SIPS. Once the optics are installed in the housing, the system is correctly tuned, and you can move the optical assembly between housings without any further adjustment.
I have a 12.5" Newtonian with a 2" Feather Touch focuser and want to use my SIPS on a second 20" Dobsonian, also with a compatible 2" Feather Touch. Is this SIPS housing the right part?
Yes, this is the exact scenario this product is designed for. As long as both telescopes have a 2" Feather Touch focuser with 1.5" of draw tube travel, you can install this housing on the 20" Dobsonian and easily transfer your SIPS optics from the 12.5" scope.
If I install this SIPS Housing on my 16" f/4 Dobsonian, will moving the optics affect my primary mirror collimation?
No. Moving the SIPS optical element between housings is done entirely at the focuser. It does not interact with or affect the alignment of your telescope's primary or secondary mirrors. Your primary mirror collimation remains unchanged.
