  1. Wow, what a difference! I had to unscrew the eyepiece about half way out to get those crosshairs focused, but that changed everything. I am now totally in love with my new finderscope. Thanks to all for your fine advice and help. Thank God for forums like this, especially when there's no instruction manual. Clear skies!
  2. Partly unscrewing the eyepiece was one of the first things I tried, but maybe I just didn't unscrew it far enough. Can't wait to try it tonight!
  3. The only knob that seems to be available for focusing the crosshairs is the knob that turns on the illumination and controls the brightness, but it seems to have minimal effect on actually focusing the crosshairs. In daylight, with illumination turned off, the crosshairs are of course crystal clear. I had assumed that focusing the finderscope itself using the front lens would automatically focus the crosshairs as well, and in fact appeared to do just that in the daylight. Turning on the illumination seems to just screw everything up.
  4. So, tried last night, but no joy with refocusing everything. Turning the knob that turns on the illumination makes the crosshairs brighter or dimmer but doesn't really seem to do much to focus the crosshairs. It's almost easier to just leave the illumination off, and estimate the center of the field.
  5. So, AlexK, are you saying that this problem can be entirely eliminated by refocusing the finderscope itself by loosening the front locking ring and rotating the front lens with the crosshairs defocused, and then refocusing the crosshairs? I thought I'd already done all that when I set it up, but maybe not quite accurately enough? Is that what you're saying? Do you use this same finderscope, and do you have clear and distinct ILLUMINATED crosshairs that do not jump around all over the field of view?
  6. Thanks, Paz. Good to know it's not just me. Just have to learn to deal with it, I guess, using the field stop to help keep centered, as you said.
  7. I recently acquired a Celestron Illuminated RACI 9x50 finderscope after nearly breaking my neck trying to use the supplied red dot finder that came with my Celestron Nexstar 8SE scope. The package was pretty beat up when it arrived, but the initial daytime alignment went well, the unilluminated cross-hairs very clear and easy to center, and everything seemed to work fine. Since the cross-hairs can't be seen in the dark, that night I turned on the illumination, and that's when the trouble started. I had a hard time getting the illuminated cross-hairs in clear focus by turning the knob, but good enough I guess, except that the center of the cross-hairs seemed to jump around with just the slightest movement of my head, and it was really hard to judge where exactly the center was. So, is it just my old geezer eyes, or is there just some trick to it that I'm missing, or could it have been damaged in transit somehow, and not working correctly? Has anyone else had this kind of difficulty, or is it just me? Thanks for any help...
  8. Thank you Cosmic Geoff for the answer to my question. Go to the category and just enter the numbers, no letters necessary. Just what I needed to know. Thank you.
  9. Yes, thank you again, Ooby, but I know how to read the manual, and I know how to select from the lists, that wasn't the issue.. My question was how do you just input the name of the object as the manual says you can, instead of taking the time to try and find the object by going and scrolling through lengthy lists?
  10. Thank you, John, but I have a different (newer?) "Nexstar+ Hand Control with USB", and there's no "M".
  11. Good point, D. I guess the eyepiece clearance would probably take precedent, as it could happen accidentally, in the dark, whereas parking the tube straight down could be done in better light and more controlled circumstances, and probably a lot less frequently, unless you always point it down after every session. Is there some reason it should be pointed down after every session?
  12. The manual says to slew to the Orion Nebula you can pick it from a list or just enter "M 042" on the hand control, but I can't see any letters on the HC, just numbers. What am I missing?
  13. The instruction manual and all the videos I saw on setting up the telescope ALL showed the OTA already attached to the fork arm mount, and just talked about setting it all on the tripod's three bolts. There were no instructions on attaching the OTA to the fork arm mount. Since my OTA and mount arrived in separate boxes, I had to figure out for myself how the tube slid into the mounting bracket on the arm of the fork mount and secured with the clamp and large quick release knob. So far so good, until I realized the standard diagonal eyepiece would hit the mount if it tried to move through the zenith. So I started reading forums on the subject and after hours of searching and reading, although many others had the same problem, the only solutions discussed were to go buy special "short" diagonals, or just avoid the zenith altogether, which just didn't seem right on such an expensive high precision instrument, but hey, what do I know? After using the scope like this for a while, I finally found the solution in a totally unrelated post. BEFORE ATTACHING THE OPTICAL TUBE ASSEMBLY TO THE FORK ARM MOUNT, USE THE HAND CONTROL TO ROTATE THE UPPER ALTITUDE GEAR WHEEL UNTIL THE TWO "INDEX ARROWS" ARE ALIGNED WITH EACH OTHER. This allows the tube to slide more forward in the mounting bracket so that it clears the base of the mount no problem. Why this is not mentioned in the manual or in any of the videos I don't know. Anyway, hope this helps...
