Up for sale is a Bahtinov focusing mask for the ZWO Seestar S50 telescope.
As described in the following post, the Bahtinov Focus Mask is used for fine-tuning of you focus on stars and distant objects which is particularly helpful when you will be stacking images. This is especially useful for the Seestar S50.
The S50 does a pretty good job on autofocus, but this can help you get from a good focus to a near perfect focus resulting in even better astrophotography.

In addition to the Bahtinov Mask, please let me know if you would like me to create a custom sale for you with any of the following Seestar S50 specific items:
- Additional Bahtinov Mask
- Diffraction Spike mask
- Filter holder - 2" threaded filters
- Dew Shield / Lens Hood
- Lens Cap
The dew shield / lens hood is especially helpful in that it extends the time the telescope can be used before dew forms on the lens, and it helps reduce extraneous light when there could be ambient light in the area.
These are 3D printed items which will have minor variances, however they are all guaranteed to fit on the S50 and work properly. If you are not satisfied with the functionality of a specific item, that item can be returned for a replacement.
These items, especially the dew shield MUST be removed from the telescope before powering it off to avoid possible damage to the scope. These are printed with carbon reinforced filament to provide increased strength, durability and heat resistance.
All items except the dew shield/lens hood will be shipped via USPS Ground in a padded envelope unless a higher priority option is selected. The dew shield/lens hood is larger and requires a small box.
*** Note: I am not responsible for any damages to your telescope due to the result of using this product ***
