I have made arrangements for the purchase of a SW 120 ED. Thank you to all for sharing your knowledge and experience.

 

Greatly appreciated!

Congrats, I even slightly preferred the ED120 to my previous Vixen ED115s. CS

Good choice. It’s not GNG, but a quick 2 trips, mount for one, eyepiece and OTA with the 2nd. Up and running still in under 5 minutes from being stored in the basement.

That's saying something! Although the Vixen was probably a little lighter in weight.

I agree a 4” might not be much of an upgrade, but if you want, you could consider a CF KSON 102 f/6 ED. It’s under 6 pounds and 20” collapsed and I use it as my travel scope. Fits nicely in a Swissgear rolling duffel for airline travel. Probably a step down optically from the 85 (only FPL-51 glass), but overall pretty nice. Here it is in my travel bag with SW AZ-GTi mount, diagonal, finder, 2 eyepieces and a Barlow. Only available used.

I second the Kson 102ED. Amazingly short and light for a 4”. You will get a bit of CA on very bright objects, but not an issue. For many uses, including travel, I prefer it to my very nice TS90 APO triplet.

That's why I kept it and sold the ED. Image brightness was a bit better in the ED. CA was like the ED100 F9. Both were comparably sharp.
