I was looking at the webpage for this telescope at Orion, and discovered under the photos that it had an icon representing "Lifetime Tech Supportrt." You might want to check them out before having someone else work on your scope. --Richard
Thanks Richard, but I do my own work as a rule.
Back when it was still under warranty the focuser developed a problem. It was causing a long scratch to develop on the draw tube for the focuser.
Before contacting Orion, I dismantled the entire telescope to see what was wrong. In the focuser there are 4 guide rollers that support and align the draw tube. One of those hardened rollers was cracked and had stopped turning.
A true factory defect.
I carefully reassembled it, contacted Orion, got an RMA (or RMS), and shipped it off to them. They replaced the entire focuser and tuned it up, then returned it to me. It's been dandy every since, mechanically and functionally until of late.
It has what we typically call a dust moot (mite, mote) on the image. Usually caused by a speck of dust in the imaging train.
I did a tear down and examination, cleaned the lens, and found nothing to cause the anomaly. Nothing on the triplet lens, nothing on the filters, nothing on the camera. Nothing I could discern anyway.
But, using darks, flats, and bias frames in processing, it disappears.
But my concern now is the appearance of this "fog", for lack of a better term, that is on two different images from two different sessions on two different nights with different subjects.
It isn't apparent in processing, only after the file is saved.
That is part of the fun of this sport, all the maddening variables to combat to get a picture. Or in my case, when I started out I made a lot of Picturds. Terrible images as I was learning.
I still am, every session, every night seems to have some anomaly to deal with. It's the challenge that makes it attractive to me. I like the images, but the mechanics of being able to find and track something I can't even see, then take long exposures of to get a picture out of it is my nirvana.
I think I'm a purest. I don't do hardly any post processing. I don't "manufacture" my pictures. The images you see from the Hubble are mono (B&W images) they colorize. They even made a Hubble Pallet to do it.
I learned with color cameras, and a great friend offered to loan me, then sold me his Atik Infinity camera, which these were taken with. Mostly manually set up, focused, and controlled using PHD2 for guiding.
Then I got a wild hair and bought a Mono camera, with a filter wheel, and later a real electronic focuser. But I'm a dummy and can't quite figure out how to do color processing. One day I hope to.
You could say my equipment has risen above my level of incompetence.
But that forces me to learn. Forces me to think. And forces me to progress.
But once in a while... everything clicks together and Wa-La. I can do it, but sometimes I struggle.
Thank You!
