Those of you with the older Clave eyepieces having the smaller, non-standard sized barrels, what are you using to adapt/convert the barrels for use with 1.25" equipment? Is there some kind of an adapter one can buy or are you making your own adapters? What's the exact outside diameter of the barrel? Any ideas or suggestions? Thanks!

I have a set of Clave eyepieces of various vintages and types and would really like to learn more about them and possibly determine when they were made. Are there any Clave experts/collectors out there who could help me learn more about what I have? What types were made when? Which versions are the best? When did they make the shift from the smaller, non-standard sized barrels to the 1.25" barrels? Thank you so much for any information you can offer!

Thank you so much!!!

This showcases some pretty amazing video of the Starlink satellites. The commentary on the Starlink satellites and their effects on the night sky at the end was really astute and well-spoken too. I highly recommend this to anyone interested in using their DSLR cameras to catch these satellites or is interested in their ramifications on astronomy.

What's the history/story of the 80mm refractors designed by Thomas Back, made by LOMO in Russia, and sold in a wide variety of tube assemblies by different companies? I have seen some from Stellarvue, APM, William Optics, etc. What about the later copies of this design sold by other companies and made in China/Taiwan?

Does anyone have the straight scoop on what's what with the 80mm refractors based on designs by Thomas Back? Which versions/tube assemblies were best? How much field curvature is in the f/6 version? What field flatteners are best for these?

How good are these 80mm LOMO lenses? How long do they take to reach thermal equilibrium and how sensitive are they to temperature changes?

Please tell me your 80mm TMB/LOMO stories, I really want to hear what you have to say!

I was getting ads e-mailed to me up until last night, did something change? I checked my e-mail settings, my spam filters, computer, everything. Did the features for membership change and you no longer provide this feature for my membership level? Is it an error or technical glitch? If it's a new membership level thing, which level of membership do I need to get this feature restored as I have really enjoyed it? I'll pay more if needed as Astromart is really wonderful and I appreciate and all of the hard work that goes into providing it. Please let me know. Thank you so much!

So, I am really confused.
