[QUOTE="BF Hammer, post: 740324, member: 48483"] I had a failure of my redneck engineering on my 2nd night of photographing NEOWISE. The Star Adventurer ball-head adapter on my rig is actually screwed into a quick-release Arca-Swiss compatible clamp. If Alt-Az mode, this setup is not such an issue, but in EQ mode and aimed low on the horizon to the northwest, the front-heavy lens makes the whole thing try to unscrew loose. And it did when I added a 150mm square light-pollution filter. I could not make it right in the dark at that location. I went to plan B which was shooting wide-field landscape on a tripod. I was going to do that anyways that night. I since modified the setup some more and this will not happen again. Unless it is critical that I take a photo in that position again. :D [/QUOTE]
