Re: New Owner of Obsession 30"


 

21mm and 31mm is probably all you really need.

IMO, I would save the money for potential upgrades to the scope itself before spending more on eyepieces that you may, or may not use as much as, for example; a really nice feathertouch focuser, a really nice filterslide, or some good dew heaters, a battery bank, a good tablet for navigation, a good astro camera, or even just some really high quality O2 and/or HA filters.

With a 30" scope, you are probably going to need a fairly large ladder, and the quality of that ladder is going to make a big difference in your ability to enjoy and or share the enjoyment of your new scope.

Those are just a few of the things I'm wishing I had purchased for my Obsession 20" classic when I "upgraded" from a UC18. I wish I spent some money upgrading scope instead of buying a bunch of eyepieces I rarely use. I wish I had bought higher quality filters, I should have upgraded the braces for the UTA on my UC18, or the center mirror bracing/adjustment setup. I've even thought about upgrading the aluminum tubing to carbon fiber (i.e. less expansion/contraction/flex)

The biggest gripe with my current setup (i.e. a fairly old 20" classic) is that the clamps I have holding the UTA on the truss rods are really quite crappy. A really great solution to replace them probably costs as much as, or possibly more than, a nice Nagler.

Just a few ideas for you to ponder.

Hope you get lots of time to enjoy that huge scope!

Hi Everyone,

After spending several years immersed in astrophotography, I decided to return to my roots in visual observation. To that end, I've just acquired an Obsession 30" telescope, complete with the original ServoCat and Argus systems. The mirror is currently being sent out for stripping and a fresh coating (IAD). Given that the largest Dobsonian I've used before was a 16" Orion, I'm anticipating a whole new experience with this one.

I'm planning to add a 21mm Ethos and a 31mm Nagler T5 to my setup. Does anyone have any additional recommendations for eyepieces?

Thanks!
