    Default Celestronís 8X24mm Zoom Eyepiece



    I purchased a Celestron 8X24mm zoom eyepiece and just had a chance to try it out. This is NOT a review of the eyepiece, as I canít do that until Iíve spent a lot of time with it. Iíll just give some first impressions.

    If youíve paid under $1,000 for your scope and amassed a small set of $15 to $60 eyepieces, this zoom will spoil you! Iím not comparing it to the big money stuff here. I took it out of the box and saw it was housed in a hard plastic case. Really nice! It weighs around 8oz and the zoom feature, though lacking click stops, works smoothly. I expected it to match my moderate and low priced plossls. My first target was Saturn, under fair conditions at best. It looked about as sharp as my plossls under good conditions! I then checked out Albireo, when the clouds cleared, and saw the best color Iíve seen from my scope! The yellow and blue stars looked yellow and blue. Zooming in on Epsilon, I split the double double. Here, it was a tie with my better plossls. I bought this eyepiece for use at the observatory, where people look in the big scope and then come outside and view from my scope to see more objects, but I can already see it will be my favorite eyepiece for personal observing. I didnít see any problems toward the edges of the field of view, but Iím no expert. 8mm will give you a nice 60 degree FOV, while zooming out to 24mm gives a 40 degree FOV. This eyepiece wonít replace your low power, wide-field eyepieces, but it might replace your 9 or 10mm kit plossls. I donít wear glasses, but eye relief shouldnít be much of a problem for eyeglass wearers. Overall, my 1st impression is this Celestron zoom is well worth the $65 shipped I paid for it. If youíve paid thousands for your scope, itís natural youíre going to want expensive eyepieces, but this eyepiece matches up well with good quality, moderately priced equipment.

    Yes I bought one for the same price on amazon and had it sent to oz, I dont have any good ones to compare it to but its the first one i have above my 10 and 25 stock eyepieces. If I had to say a negative thing it would be that as you zoom in the lens you have to refocus the scope as well. But very happy with the bigger glass.

    I forgot to mention I went out later and viewed Mars. I got my best view of the planet in spite of way less than ideal conditions. I also noticed it doesn't take much re-focusing when you change powers. I was hoping for a strong 8-12mm, as I'm missing both 8 and 12mm eyepieces, and this eyepiece covered them well. Weaknesses? Well, I'm not impressed with the 24mm at 40 degrees. It looks great, as long as you don't use it as a finder. My 52 to 60 degree low-power eyepieces are much quicker to find things with.

    Phill- I just saw your post after my 2nd post. Yes, you do have to re-focus as you go, but I found it to be minimal. I also might mention it's a tall eyepiece and shorter people might have trouble viewing from some positions. My plan is to just take out the zoom and drop in a stock plossl which will lower the eyepiece about 3".
