Important: This is a 3-D printed mask. More information is below.
Bahtinov mask to aid in focusing your SeeStar S50 All-In-One Smart Telescope # SEESTAR-S50.
The ZWO SeeStar S50 Smart Telescope has auto focus built in and it works well, so an additional focus mask is not necessary. However, some users have reported that the use of a Bahtinov mask to verify/improve the focus before starting their exposures has been beneficial to them. This mask features two extended tabs to make installation and removal a breeze.
With the mask on, you can see a diffraction spike pattern. Focus until you achieve a symmetrical pattern. Once the best focus has been achieved, you can remove the mask and use the telescope normally.
This mask is deliberately designed to be smaller than the recessed lens cell of the SeeStar. It does not have a snug fit like an end cap would. This is intentional so that it can be removed very easily after focusing is accomplished and the imaging setup isn’t disturbed during removal.
3D printed from PLA.
Color of current stock is silver-gray but is subject to change without notice.
Sold individually.
Important notes:
- Please note that this is a 3d printed product typically made of a plastic material (see item description above for the exact material used).
- The cosmetic finish on 3d printed items will vary and will not be as polished or smooth as metal items. It is not uncommon to have imperfections such as scratches, scuff marks, or inconsistent surface finish. However, these have no functional impact on the use of the item.
- 3d printed items should not be subject to very high operating temperatures (for example, left in storage in hot sheds, cars, etc.) and exposure to sunlight should be minimized.
- Notes on some commonly used 3d printing materials:
- PLA: Most commonly used material in 3d printing; derived from corn or sugarcane so is biodegradable; basic PLA should not be exposed to over 125° F and exposure to sunlight should be minimized; available in custom formulations that can withstand higher temperatures and solar exposure.
- PETG: Another very popular 3d printing material; has smoother surface finish; water resistant; should not be exposed to temperatures usually above 160° F.
- TPU: More expensive but more durable; is elastic and resistant to low temperatures, abrasion, oil, chemicals and wearing; can withstand ambient temperatures up to 175º F
- ABS: A strong material used for strong and durable parts; able to withstand temperatures of up to 200º F
