Getting Started using a Smart Phone
I've been dabbling at capturing images through various telescopes for a couple of years.
I had very limited success with trying to hold a smart-phone camera up to the eyepiece of a Celestron 128EQ on an equatorial mount.
Things got quite a bit easier when I invested in an inexpensive Phone Clamp that clamps onto the barrel of an eyepiece. The cheap Phone Clamp had a couple of degrees of freedom for aligning the phone with the eyepiece. Hard to use. Easy to knock out of alignment.
I purchased a Celestron Phone Clamp that had more adjustments for alignment, and it greatly simplified capturing quick images with a phone. Once the phone is clamped, there are three knobs to turn for the XYZ alignment of the phone lens with the eyepiece lens.
Scott, is this the Celestron Nexyz that you're using? If so, I purchased one of these as well and can agree with you that it offers a lot more adjustment than the standard clamps, one of which I've purchased and returned. Unfortunately it costs about 3X more than the simpler clamps.
Yes, it's the NexYZ product. I got it on the conference floor at NEAF last spring. They were offering a significant show discount.
I have the $30 or so phone holder from Orion, works great on most eyepieces, but I did have trouble with a variable a while back. I really like the one I have, simple and holds all phones I have tried so far. Jack
