Hi,

 

Silly question, Does the Meade 9.7mm Plossl different form Celestron or Orion 10mm Plossl

The same thing apply for the 12.4mm and 12mm OR the 26mm and 25mm

 

The reason for this question is that I used t use the 10mm 15mm and 25mm and I lost them in a family dispute, now I want to replace them, I am offered a Meade set the include everything except the 26mm

 

 

Thanks in advance

Some of the Meade are 5 lenses and some are 4 lenses.  The early Japanese are 5 lenses (Masuyama clone), they later changed over to 4 lenses and shortly thereafter manufacturing was moved to China, which are all 4 lenses.

9.7mm is close enough to 10mm that you won't really notice a difference. Same thing for the 26mm and 25mm

12.4mm is far enough from 15 that you might want another 15.

My favorite Plossl is a 17.  A 2X Barlow effectively makes it the same as an 8.5 but without the super short eye relief.  Effective and inexpensive for planetary.


Or, take this opportunity to search out nicer eyepieces.  What telescope are you using?

I am using 120mm f/8.3, C8 f/10 and C90 f/13.9

I used to have ST80 f/5, planning to get it back soon

 

Oh, i forgot to mention I have 2" eyepieces set with 1.6x Barlow

I certainly wouldn’t bother replacing a $40 10mm Plossl with a $40 9.7mm Plossl if that is what you are asking.

No, I used  to have Orion's 10mm and 25mm  plossls and I am skeptical for anything below 10mm, as I can get to below 10 with a 2x Barlow and I don't want to end up with wasting money on anything less than 10mm, TeleVue and other quality eyepieces are exceptions

These eyepieces are 4 elements and made in China, never saw a 5 elements plossl at all

Seems the latest made versions from later 1990's- 2000 on were the least at being super good.  The smooth sides were very good and the first versions with the rubber grips.

For quite some time they have been four element eyepieces made in China, but that wasn’t always the case.

Yes, I have a 10mm and 25mm plossl that come with a scope. Then I have 3 of the Japanese Meades that have Japan stamped on the barrel.A 26mm, 9.7mm and 12.4mm There is a noticeable difference between the two in image quality.

A quick question...Why do EP companies design EPs in odd numbers?

Like the Meade 6.4, 9.4, or the TVs 18.2, ect...

I just got a TV 7.4mm off ebay, you think they would just make a 7.5mm EP?

I just picked up a set of Taiwan made Meade 4000 plossls.

They are close to parfocal.

When I compared the 15 meade to the 15 celestron I had to crank the focuser a lot to get it to focus.

I have not compared the view extensively, on first glance they seem roughly the same.

Happy days!!
