Product Description This is a set of six dedicated optional masks that dramatically change the star images of the Seestar S50. These were designed and published by me on MakerWorld, but I am selling them here for those who do not have a 3D printer. I have also introduced them on YouTube, but this set does not include a dew shield. Please be aware of this. ※Currently, a 2-inch filter adapter prototype can be included. Please contact me if you would like one. ■ Set Contents and Effects ・Squ / Hex / Oct: Adds beautiful 4, 6, and 8-point diffraction spikes to stars. Designed with a focus on balance. ・Nov (Nova): Gives a dramatic glow with a unique halo and rainbow-colored diffraction spikes. ・B-TNV (Bahtinov): An essential tool for precise manual focusing. ・Lens Cover: For protecting the lens during storage. This is a set of the above 6 items. Please refer to the photos for details. The images collaged with each mask are unprocessed images for comparison purposes, using only stacking. Please use them as a reference for changes in star images. Alnitak + Flame Nebula: Approximately 10 minutes Pleiades: Stacked with an exposure time of approximately 5 minutes. With the Bahtinov mask, focus is achieved when the spikes intersect in the center, as shown in the photo on the bottom right. ■ How to Use Easy to attach and detach, simply insert it into the front of the lens. Please be careful not to get it caught when storing the Seestar. ■ Sample Images M42 Orion Nebula NGC2244 Rosette Nebula NGC2175 Monkey Head Nebula These are images processed with AI denoising, with the stacking times displayed on the image band. ■ Notes on Purchase ・Because it is made with a layered 3D printer (multi-color printing), there may be slight layer lines or minor crushing of identification marks. ・Extremely fine stringing may remain, but products are considered acceptable if they do not affect use. ・Made of PLA resin, so avoid leaving it in a car where it will get hot. (It will easily deform in a car in the summer.) For those who understand that this is a hobbyist's creation, please enjoy a new stargazing experience! #Seestar #SeestarS50 #SmartTelescope #Astrophotography #DiffractionMask #BahtinovMask #Astronomy #S5OP
