Equipment Details:

Canon R6, Canon EF 300mm f4.0 L, RF-EF adapter, Monfrotto 055 Tripod with MVH 502 AH fluid head. I used my iPad mini in conjunction with the Canon Camera Connect app to sight in the area of interest. I also use this combo to change camera and lens settings and activate the shutter.

Post-processing Details:

Photoshop and Topaz adjustments

Image Details:

Both images are of Comet ZTF below and to the left of Alderaban. The image on the left was shot at 4 seconds, F4.5, iso 25,600. The image on the right was shot 7 minutes later at 2 seconds, F4.5, iso 25,000. Between the 2 shots I slightly repositioned my camera. I do not have a star tracker drive.
