What is the primary purpose of the Baader Molded Plastic Cap?
The primary purpose of the Baader Molded Plastic Cap is to protect the open port of a T2 Quick Changer from environmental contaminants like dust, dew, and pollen. When you remove a camera or eyepiece, this cap seals the optical path, keeping your telescope's interior and any downstream filters or sensors clean.
Will this Baader cap fit other T2 accessories besides the Quick Changer?
It fits Baader's Zeiss-dovetail quick changers. Baader also supplies it with the Mark V Giant Binocular, the DADOS Slit Spectrograph and the 2" / 1.7x Glasspath Corrector for Newtons.
How does the Baader Molded Plastic Cap help when imaging from a dusty field?
When imaging from a location with airborne dust or pollen, swapping accessories can introduce contaminants onto your sensor or filters, resulting in "dust donuts" in your final image. The Baader Molded Plastic Cap allows you to immediately seal the optical train after removing your camera, preventing contamination while you prepare your next accessory.
Can I use the Baader Molded Plastic Cap when disassembling my mobile setup at a dark sky site?
Yes, this is an ideal use case. After a long night of imaging, you can use the Baader Molded Plastic Cap to seal your telescope's focuser or visual back before transport. This ensures that no dust or debris enters the optical tube on the drive home, keeping it clean for your next session.
Is the Baader Molded Plastic Cap included with the T2 Quick Changer?
Yes. Baader supplies this cap with the T-2i Standard Quick Changer (#2456313), the T-2i Heavy-Duty Quick Changer (#2456313A) and the T-2 Standard and Heavy-Duty Quick Change Systems (#2456321, #2456322).
