Shot Helix in Ha for a couple of nights for a total of 7 hours at 10 minute subs with the new Esprit 100ED and oh boy is this thing a HUGE improvement over my old north group refractor. For one thing, the focuser isn't something you'd get out of a happy meals and actually holds the weight of my camera.
Now to the not so good part. I've been having issues with the camera. I'm getting light leak from my filterwheel when I'm shooting flats (empty filter slot next to the narrowband filter) which means that I can't get a decent flat calibration or darks without removing it from the scope and covering the whole camera which doesn't make sense for flats
. Also, if you look at the full res image, theres this weird horizontal noise line that's present. Has anyone come across something like this? If so, what's the solution?
