Jupiter & Moon

All of these pictures need me to master the use of a Bahtinov mask to get a sharper image.
1/30 sec., ISO 100, 25mm eyepiece projection

The prime focus pictures of Jupiter showing its Galilean satellites suffered some weird swirl.  I think my exposure delay was too short (2s) for the scope to stop moving after pressing the button.

Some of these prime focus images are better than usual because I am now using a 2" diameter adapter for the camera.
1/200, ISO 100 2000mm f/4.5 converted to gray scale

This picture of Tycho may benefit from GIMP, but it is late and GIMP loads slowly.

Saturn was too close to the Moon; just washed out the sky.
