Rear Soft Filter for Starscapes (Medium) - With Defects

【Overview】
This is a homemade rear soft filter for astrophotography (see photo 1).
When attached to the rear of a wide-angle lens, it suppresses star trailing in the four corners of the image and enhances the appearance of bright stars, making them appear larger.
Since its release, it has been loved by over 200 customers.

The 訳あり品 (reason for discount) items have slight unevenness in the coating during production. This does not significantly affect the filter's performance, so they are sold at a lower price.

【Size & Material】
Size: 105mm x 100mm
Thickness: 125μm (0.125mm)
Material: PET (harder and more scratch-resistant than polyester)

【Actual Shooting Examples】
Photo 2 shows a starscape taken without a filter. Photo 3 was taken with a LEE No.3 filter. Photo 4 was taken with our homemade Medium filter. By comparing photos 3 and 4, you can see that the effect is almost identical to that of a genuine product.

【How to Use】
This filter is attached to the rear of the lens. Please cut it to size with scissors and secure the sides with double-sided tape.
It can be used in either direction, as there is no front or back.
Refer to photo 5 for how to attach it to your lens.
(If your lens has a mount on the rear side, please insert the filter into the mount.)

【Compatibility】
For compatibility with filters sold by various manufacturers, please refer to the table in photo 6.
