Re: Usability Question--Update

John, ? Thanks for this. ? I have two finders:? A 9x50 right angle finder (with illuminated crosshairs), and a Telrad.? Both are aligned perfectly with the eyepiece.? So both are off the same amount as on my eyepiece.? ? I¡¯m not sure why people keep asking about my finder(s); when a faint fuzzy is off the eyepiece FOV, it doesn¡¯t matter what I have for a finder scope, since no finder I¡¯ve ever used will show, e.g., M51. ? Yes, I can keep swapping eyepieces; I have a full range of 82¡ã, high-quality eyepieces.? And I could use the reducer I bought with the scope. But I guess I¡¯m just spoiled by my old Meade scopes which (whether in Alt-Az or polar mode) would have every single object centered on any eyepiece (even on a KAF-401 chip, which is tiny¡ªunder 10 arcminutes diagonal, as I used it on my RCX400)), first time and every time.? As much as they charge for this mount/electronics, it should be able to do as well, IMO. ? Mark ?

A C925 Edge HD is what I use, but I most often have it coupled with a 0.7X Celestron Focal Reducer for wider field as faster optics. While I have heard many reports of mirror flop with this scope, I really haven't seen it too much with mine, or if it's there it has not caused me much of a problem.
When I started with this scope, I bought a 17mm and a 23mm Luminos eyepieces which are enough for my visual needs. But I now always have a camera on the back and rarely use them. But for finding objects during visual, I still have a cheapo 50mm Plossl (off brand) that I use for finding stuff. Then switching to a higher power eyepiece is what to do after centering the object.?
But what are you seeing in your finder scope? Are you still off target even with that? If you are slewing around the sky at F10 with 17mm eyepiece, expecting each GoTo to be in its FOV is asking a bit much, IMHO.
John
