So I got my C9.25 the other day and have ZERO eyepieces, unless you count the old Meade MA25mm I am borrowing from my 25-yr-old 60mm refractor. I have searched these fora and have been impressed with all of your helpful advice.

Simply put, I am not going to go out and spend $2,500 on eyepieces. At least, not yet. A lot of people have suggested getting a 2" diagonal and then getting one or two Panoptic EPs (e.g. 30mm, 41mm) or something similar. That is the plan. That is also about $800. From what I've read (never tried one) the advantages of that kind of setup are worth it. (Thoughts on this are welcome too)

For the shorter focal length EPs, though, I'm wondering if I need to blow that much cash. I've read allusions on here that an F/10 scope like mine is "easy" on eyepieces, and can't help wondering if I can "get away" with something like the Celestron EP set (or Meade or another) that gives you 5 or 6 Plossls plus a Barlow (two words I didn't know two weeks ago) to fill out that part of the spectrum (10-25mm, say).

A few people have suggested zoom EPs, and that would take care of the issue as well. I can see myself being somewhat lazy and liking a zoom lens (Hyperion?) tremendously.

So if I get a 2" diagonal, a couple Panoptics, and a zoom or a cheap Plossl set, I'm in at around $1,000, which is doable. Help!

Happy Thanksgiving to all.

I had the Baader 8-24 zoom and it covered all the bases well in my SCT. Highly recommended as a first/only eyepiece. Later, you can try a specialty eyepiece or two at a star party to sample what may interest you next.

I would go for the Hyperion Zoom over low end Plossls anyday. I've got one and lunar-planetary performace in my C-9.25 while not as good as my XWs and such is impressive. As to a widefield DSO eyepiece I got a 20 ES100-sale priced at $293 with CN discount to boot-a couple of months ago and it's excellent in my SCT. My cats not of the Edge variety but coma in the ES100 and my Ethos is minor. David

You only need 3-4 eyepieces. You could get a Panoptic plus a couple good Televue plossls and a good barlow. That would be a cheap solution. But why not throw in some Naglers if you have $1K?

My proposed list (buy used):

Pan 24 mm
N16T5
N9T6
Barlow

+1 for the zoom, go for it, for my SCT I've had both the kit & the Baader Hyperion 8-24mm zoom and the latter yielded better, clearer views, not to mention the convenience of not having to swap EP's.

I might be inclined to try the astro tech paradigms

Provided the illusion of f/10 being easy on eyepiece design is a reality, I can't see why an inexpensive 8-24 zoom like a Zhumell or Celestron wouldn't work quite well for you. I've used the Zhumell model in my f/6 Newt and it's quite nice. Actually, it's not impossible that spending much over $70 for a set magnification eyepiece is a waste of money at f/10 and you could be all setup for under $500.

..... can't help wondering if I can "get away" with something like the Celestron EP set (or Meade or another) that gives you 5 or 6 Plossls plus a Barlow (two words I didn't know two weeks ago) to fill out that part of the spectrum (10-25mm, say).


Plossls will work very well with your scope and there is no reason not to use them. However, in the shorter focal lengths (ie less than 12mm), eye relief is tight so they can be uncomfortable to use.

More importantly is that the eyepiece kits typically have some very short focal lengths that you are unlikely to ever use. Likewise for the Barlow. You will have no problem reaching high magnifications with readily available, comfortable eyepieces. Probably half the kit will sit unused, more if it contains filters and other accessories.

I like the suggestion of the 8-24 zoom for higher powers. Add a mid power wide field eyepiece around 30-32mm and perhaps something for very low power views later.

Be careful that you don't fall into the trap of chasing high magnifications. Such views are not normal and are only useful under exceptional seeing conditions. You won't go there very often if at all.

Just get the whole set of 6, you may not use the 5mm much, but that is the only one that may not get used a great deal owing to the magnification delivered.

Leave the idea of going to 2" until you are more used to the scope, what it can do, what you want it to do and what you want to do. Sometimes it is best to take things a bit slower.

I dont think the 5 or 8 would get much use. the 15 would likely be redundant. Also no abig fan of two inchers in an sct. only a few objects worthwhile open clusters mostly.
