Improving Celestrom Ultima spotting scopes

Hi Adrian, did you need any adapters or parts to use the Baader eyepiece with your celestron ultimate 80?
Eric, I did not need any adapters to use the Baader eyepiece with the Celestron Ultima 80. The Baader Hyperion Mark III already comes with several additional adapters built in to it, so it's modifiable to fit a couple of different sizes.

When I took it out of the box, I removed one of it's adapters, and couldn't get it to fit the Ultima 80. I scratched my head a bit until I finally realized that there was another adapter I needed to remove in order to get it down to the 1.25" size. Once I removed that adapter, it screwed right into my spotting scope.

From my conversation with the less than optical expert at Celestron was that the Ultima series was unique in that "there were no optional eyepieces for them. The eyepiece mounting is different from the normal 1.25" and I think 0.5" slip in sizes.

And, I am very happy with your success with the new Baader zoom eyepiece! I am now waiting to see if you can see bullet holes at 600yd with a bit of mirage!
 
Thanks, Adrian. The reason I asked is I had an opportunity to compare my 65 Regal with a 65 Vortex Razor. The Razor had noticeably better acuity and sharpness.
 
I just won an auction on eB*y for an unused Celestron Ultima 80 without eyepiece for $52 (incl shipping). Now to decide on the eyepiece - I've decided on a Baader Hyperion - now to decide on a fixed length or the click stop 8-24. At around $250 the 8-24 kind of bumps my budget spotting scope cost into the lower vortex range but if the quality of this combo warrants it I will go for the variable.

I look forward to sfldiver's evaluation on his celestron/Baader!

The scope has a 480mm focal length so a 13mm eyepiece should yield about 37X magnification. As I understand it, the eye relief runs about 1/2 the ep focal length which should work well with glasses.

Thanks to sfldiver for the tip on researching the birding forum - those guys are something else - and I thought we were picky about our equipment lol.

Can you please supply the Baader site where you obtained this info?

I am looking forward to the end results for the 100mm scope test.

Thank you,
Don
 
I finally recieved the celestron ultima 80 body and fitted the Baader Hyperion 8-24 eyepiece. This makes a very nice and useable combination although I don't have the original eyepiece to compare.
The Baader eyepiece is a work of art and I will be keeping it. If I was keeping with a budget theme I would probably get a non-variable eyepiece from the same Baader Hyperion line for$110 or so in the 13-24 mm range.

I can easily see 22 cal holes at 100 yds with the eyepiece set at 24mm.
 
I realize it's been a while since this thread was active, but I finally made it out to the longer distance range with my Celestron Ultima 80 spotting scope with the added Baader Hyperion 8-24 Eyepiece, and as promised some time ago, I wanted to give a range report. Let me just say, I was surprised at how well my spotting scope performed. I was at a range with up to 1000 yd shooting for two days, and I really got a chance to put it to the test it over the two day period.

When I arrived the first morning, the weather was cool (40's and 50's) and the skies were perfectly clear (It did warm up into the 70's later, but was always very sunny with little to no cloud cover ever). I setup the scope and pointed it out to the 600 yd mark. Before I even put out my target, I noticed there was a large 18" splatter target setup at the elevated 600 yard point. At that distance, I could clearly see the multiple bullet holes already on the target. Granted, these were spatter holes, but I had no problem seeing all the holes on the target. I too happen to be using splatter targets, and had no problem seeing the details of my my 30 caliber bullet holes at 600 yds. My buddy was also shooting at the steel targets (8" and 12") at 600 yds, and when I spotted for him, I had absolutely no problem seeing the bullet hole details of his shots on the white and orange freshly painted steel targets.

At one point, I saw a shooter venture out the 1000 yd mark to place a target. He actually placed a large silhouette target of a villain pointing a pistol back at you. I'd guess the target was 36" by 24". I could easily see the detail of the target. However, I was not able to see bullet holes on that target, as it was non splatter, yellowish in color with the outline in thick black ink. There were however several steel targets at the 1000 yd mark, and I was able to clearly see bullet marks as they hit there.

I do however want to mention a couple of things. First, when I packed up all my gear before the 3 1/2 hour drive to the range, I forgot to pack the original eyepiece that came with the Celestron Ultima 80 scope. I would've loved to compare the original scope eyepiece to the added Baader eypepiece, because I now have no way of knowing how well the original eyepiece would have performed under those clear conditions at that distance. I don't think the original eyepiece is bad, I just think the Baader optics are superior, and that increased optics quality makes a difference when seeing detail at that distance. I also wanted to report that on both days, as the day went on and the sun got stronger, we did get a mild amount of mirage kicking in. When that mild mirage kicked in, I did have difficulty, and often couldn't see the bullet holes on the splatter targets at 600 yds. I've experienced a strong mirage at that range in the Florida heat before, and when the mirage is kicking, even at shorter distances (300 yds) it's tough to see any bullet hole detail with any optics on any target. I'm also not sure how well I'd see the bullet holes on non-splatter targets at that distance. I noticed someone shooting at a large white paper target with the targets in red ink, and I did have difficulty seeing his bullet holes at that distance.

I also wanted to mention that my buddy was amazed at how well the spotting scope performed. He was previously at that range with me when the Florida sun was blasting and the mirage was heavy, and we were seriously frustrated with any optics (riflescope and spotting scope) even at 300 yds. However, on these two day, he loved the spotting scope and felt that the approx. $500 overall investment was money well spent.

Given this weekend's experience with the spotting scope, I'm more than happy with the upgrade to the almost $300 Baader eyepiece on the Celestron spotting scope. Given some of the prices I've seen out there for quality spotting scopes, spending under $500 (approx. $170 scope & approx. $290 eyepiece & $20 cover) appears to be a very viable option for a respectable spotting scope setup for longer distance shooting at the range.

Attached are a few pics of the finished scope and replacement larger eyepiece compared to the one it comes with.

What is the eye relief like when using the Hyperion EP? Usable with glasses?

Anyone know how it compares to the Kowa 25x long eye relief EP?
 
If you can figure out a way to put a fixed astro ep in there you would be shocked at the improvement. I have an older one with a fixed televue ep in it that rocks.

If you want the best clarity get a 80mm app refractor telescope with a fixed ep of whatever power you want. Check out some of the explore scientific.

The Baader eyepiece has a wider view than the stock eyepiece. Unfortunately, you need to get real close to the eyepiece to get the full advantage of the wider angle. Therefore, similar to the stock eyepiece, I have diffiuculty using the spotting scope with glasses. As a result, I tend to lift my shooting glasses as I approach both eyepieces to ensure I can get the best view of my target.

Im not familiar with the Kowa scope, so I can't speak to that.

I agree that a powerful fixed eyepiece would be great. With the Baader Hyperion, even though its adjustable (8 -24), I use it in its most powerful setting constantantly.

I happen to already have a MkI Hyperion Zoom so I asked Baader if it was compatible with the Ultima scopes. Turns out that it is.

Removing the 1.25" nose piece from the Hyp. Zoom exposes a M36.4 thread. I assume the Celestron zoom has the same thread.
 
I've done the magnification calculations for the various settings.

For the f6 80mm scope, fl 480mm;
8mm = 60x, 12mm = 40x, 16mm = 30x, 20mm = 24x, 24mm = 20x.

For the f5.4 100mm scope, fl 540mm;
8mm = 68x, 12mm = 45x, 16mm = 34x, 20mm = 27x, 24mm = 23x.

Resurrecting an old thread here, if I understand the info in BSJ last two posts. With the celestron ultima 80 and the Bader click magnification eyepiece you still get the OEM magnification but with better imaging.

I was thinking that the 8-24 was going to be the magnification, and did not know that it needed to be calculated into actual amount of magnification. Happy I stumbled onto this old thread. Of I am understanding things correctly I'll be shopping for a new eyepiece.

Thanks
Erick
 
While not the Ultima spotter, I have had a Regal 65ED for quite some time. Use it at 600 and 1000 for subtle mirage changes that my NF won't pick up without taking it out of focus. I put in a 8mm Baader Hyperion Wide view 1.25" eyepiece and have been very pleased with it so far. IMO it picks up light a tad better with just a touch of additional sharpness, all the way to the edge. Colors appear to be the same. The extra field of view is nice. This is all compared to the stock 16-48x eyepiece that comes with the spotter. It would have been nice to compare a 5mm as well but for now I'll stick with the 8mm. Eric in DL
