Based on our popular RedCat Astrophotography pack, the RedCat 51 Eclipse Photo Pack adds a high quality solar filter and Sirui Carbon Fiber Tripod. This is a perfect kit for airline travel, since you can fit everything in a standard size carry-on. Even better, it makes an equally great night sky astrophotography setup!

This is a BYOC (Bring Your Own Camera) package includes all the basics - the RedCat 51 II-U, Chromium Solar Filter, star tracker mount, and tripod.

If you will be using the RedCat with a DSLR or Mirrorless camera, be sure to also purchase the correct M48 t-mount for your camera model (see below).

The RedCat 51 provides a wide-field 250mm focal length imaging scope that pairs perfectly with the light and portable iOptron SkyGuider Pro tracking mount. Because the RedCat and camera can be on the heavier side, we've added the William Optics counterweight extension bar to keep things in balance.
