Thank you. I"m glad you found it useful and liked my accent too!

Great run-through! I've been a bit of an eyepiece hound over the years, and because I rarely sell or get rid of them, I probably have over 100 eyepieces Ive collected over 40 years observing. Ive found I have less of an appetite for any eyepiece higher in power than 7mm. As you mentioned, seeing conditions have to be just about perfect to use many of the higher power eyepieces. Ive found my sweet spot in the last couple of years with the 7mm and 18.2 Delites, a 9mm Nagler and a Baader 8-24 Zoom. I can accomplish most everything I want to do these days in a given session with that group, unless I want to take in a major expanse of sky, and I'll go to one of my Explore Scientific deep sky EPs, but the 12-15mm eye relief is tough if Im wearing glasses.

Thank you. I used to try out everything starting with 24mm and then 16mm and then 11mm Televue I love and then try one of the highest magnifications which rarely worked but now I just go straight from 24 to the 7mm Nagler unless I'm looking at planets and then I put on the 3X barlow with the 24mm but I really would love to have one of those 100 degree Ethos eyepieces but the price is a bit too steep for me.

Hello to Nuremburg, Germany and thank you so much!

Great to look at your collection and learn, thanks Tsula. Optics are awesome! Tele Vue also make a standard Plössl design (the 40 mm with 43 deg AF was my first Tele Vue ocularI). I didn’t realize the DeLite was a modified Plössl design. The favorite TeleVue in my modest collection is the now discontinued 22 mm Panoptic-brilliant. For high power the 7 mm Nagler Original is great. I inherited my Grandfather’s 1974 C5. It came with 0.965 diagonal, a 25 mm Kellner and a 10 mm Orthoscopic ;-) kind of like looking through a narrow copper pipe :-)

Thanks. I bought a couple of Orthoscopics after I made this video and I thought they performed well but it was a big shock to look through after using my other huge FOV eyepieces-- yes kind of like looking through a narrow pipe.

At the beginning of my astro career I also fell for certain high magnifications, which was very naive. Ultimately an 8mm on a 152/1200 refractor was the best solution. I live near Vienna and the light pollution is exorbitant. But on an extremely cold and dry winter night, my Baader Hyp. 5mm really worked really good and clear. That was a real joy because I thought there was something wrong with the glass. Yes, you're just adding dirt of the atmosphere, and you shouldn't forget that. This probably only happens once in a lifetime to suburbanites.

Soon this place will be just like Denver (population 720,000) and completed light polluted. I live on the edge of town but the development is even creeping out here and now there is a distinct sky glow coming from that direction. It's a Bortle 3 but I would guess in two years it will be Bortle 4. I use an SQM for sky quality measurements and can often get readings of 21.37. That's about the best I can get on a night of good transparency and it's only on those nights that I can see stars of magnitude 6. More often I can only see up to magnitude 5.

“Most of my eyepieces happen to be Televue”. So sorry to hear that. Lol!!! They make excellent products. Wish I had that same “problem”. Most of my collection consists of meade series 4000 plossels. I do however have a Televue 8-24 zoom which I use a lot for moon and planetary viewing. I recently bought a Baader Hyperion 8-24 zoom. I will do a bit of comparison once the weather gets a little cooler. Zooms kinda get a bad rap but I really like them. Thanks for another great video. Wishing you clear skies.

The Televue 3-6mm zoom is outstanding! it has a constant 50 degree AFOV Outstanding for fast refractors, it would be perfect for a TV60 as it yields every magnification from 60X to 120X Outstanding for small fast refractors. P.S. your 32mm Televue is a PLOSSL!

I also have a Baader Zomm and love it. When I have guests over to look through, I don't have to fiddle around with all sorts of eyepieces. In general, if you want something quick and without a lot of lugging, it's a good thing. If I notice that there is more to be gained from it, I put in an appropriate eyepiece. Zooms are suitable for the first review.

I recently got a Explorer Scientific 4.5mm 82 degree eyepiece and a Televue Delite 3mm for lunar and planetary observation. I didn't want to use a 2" barlow all the time with my telescopes because everything just gets heavy. So I settled the problem by getting those two eyepieces. They're lightweight, bright and clear, and nice wide field of view. Baader Morpheus eyepieces are lightweight too. I have the 9mm and supposedly it is 76 degrees of apparent field of view but it seems much more, like 80 degrees. Excellent eyepieces. I have that Apertura 2" diagonal. It's great. What model number is your Baader?

I bought the Baader diagonal in three parts-- T-2 Star Diagonal Prism and then the T-2 nose piece and then the focusing eyepiece holder 1.25" T-2. I did not get the click lock which costs even more than the three pieces I bought but it is my best diagonal. I really want a 100 degree eyepiece but I cannot justify the price.

Great advice.....now all I need to do is win the lottery 🙂

Hi Tsula, thanks for your videos. What eyepieces do you recommend for viewing planets and nebulae on a Celestron Nexstar Evolution 8”?

@tsulasbigadventures

6 ай бұрын

For planets I start with a 26mm super plossl to center a planet and then I use a 10mm to get in closer on the planets with my 8" Schmidt-Cassegrain. That gives me 203x magnification which is pretty good for planets. If the seeing is excellent you can push the magnification even higher. So, for planets I bought two inexpensive orthoscopic eyepieces from Baader a 10mm and 6mm and they work great for planets. The seeing has to be really good in order to use the 6mm and that's really pushing a 2032mm focal length telescope like the Evolution 8". For nebulae I start with my 36mm to locate and center, and then depending on what the object is I might be able to increase the magnification from there with the 10mm. The 36mm is a Baader Hyperion but any number of plossls in the range from 26mm to 36mm would work great though for the Evolution 8". You can usually push the magnification with the brighter nebulae but some of the fainter ones you can't magnify too much or it disappears. You have to experiment but I've found that with my 8" SCT I can see a lot with the 36mm but the 26mm works as well. I think my 8" telescope came with a 26mm super plossl that works well but the 36mm Baader Hyperion has a bigger field of view and I personally like that. I hope that helps.

The view of the craters on the moon with the 90mm scope and 3mm eyepiece was just spectacular. I think that 90mm telescope has a 540mm focal length so that gives a 180x magnification-- just perfect! To use the 3mm on a telescope any bigger than that requires exceptional conditions which is rare.

Hello Tsula, I was wondering what you thought about which eyepiece would be a good next pick , I have a Apatura AD8 ( 8"Dob ) w/a 1200mm Focal length , it has a fair f stop of 5.9 I'm 63 years old so my pupils I guess don't dilate as large as they use to ( exit pupil concern ). I am looking into upgrading a Medium power level eyepiece. I already have a TeleVue Nagler 7mm for my High Power. what I'm looking at are the TeleVue Nagler 13mm or the TeleVue Nagler 16mm. Do you have any advice which one would be the better choice in your option ?? Best regards!

@tsulasbigadventures

Жыл бұрын

I also own the Televue 7mm Nagler but it's not my favorite eyepiece. Are you dead set on the Televue 13mm or 16mm Naglers? I have a 16mm Explore Scientific that I really like. It has 68 degree FOV and adequate eye relief. I recently bought a Baader Morpheus 9mm with a 76 degree FOV that has great eye relief and is a great eyepiece but a bit pricey. If you are just deciding on the 13 or 16mm Nagler, I would personally go with the 13mm because that gives you 92x magnification for your telescope and that's a good range. But the issue you are raising is about eye relief which is a different matter. So, if you like the eye relief on the 7mm Nagler then I would say that the 13mm Nagler would be a better choice for you. Hope that helps.

I use the T-2 90 on a 6" f/7 refractor and I'm very happy with it. I use a maxbrite on a little 90mm f/6 refractor and I'm very happy with that set up. I had also bought a Baader erect image I was going to try out. Those can cause aberrations but someone told me they weren't bad. So, I wanted to see for myself but before I could even try one time criminals broke into my car and stole it along with a lot of other astronomy equipment. So, I never even had a chance to try it out. Erect image diagonals are known for causing some aberrations if not made well. But the other diagonals made by Baader caused no aberrations that I could detect. And the BBHS is to die for.
