SV 110 ED

Posted By Stephen Shlafer

Returning to Astronomy and have just purchased a SV 80mm ED. I don't take photos and plan to get a SV 110 ED before getting a larger Dob.
Anyone with experience with the 110?
I have ordered various ES eyepieces and 2 SV eyepieces.

Teeter 8' Dob

Planning to get one in the future to complement SV ED refractors. Thoughts and reviews would be appreciated.

I have a SV 80 ED and soon will have a SV 110 ED.
Can I view the sun safely and well w/o purchasing a Lunt or Coronado 60mm? Thinking of Baader products specifically.

Baader Maxbright

Thoughts on this binoviewer with a SV110 ED would be appreciated.

6" Dobsonians

Do 6" dobsonians need a cooling fan for the primary mirror?

Lucky me

Soon I will be the owner of a new SV 80ED and a new SV 110ED.
Vic doesn't make these anymore. I am fortunate indeed.

Useful magnification to split double stars

Posted By Stephen Shlafer

I read that it's 2.35 x the diameter of the objective according to Dawes Law.
How does one arrive at that number?

The price for a Lunt 60mm H-a pressure tuned solar scope about equal the price of a SV ED 60 f5.5 plus the Daystar Quark.

I have a SV ED 80 f/7 and will soon have an SVED110. I can't view the whole solar disc with the the the 110 and probably not well with the 80.
Apparently, according to Daystar via Stellarvue, I could view the whole solar disc with the Quark if I use a 25-32 eyepiece with the ED 60.
I won't do terrestrial viewing, but I think that the ED 60 would be a great lunar scope.
Though the Lunt quality sounds tempting and of course there are great lunar viewings available with the 80 and 110, the portability and quality of the SV60 in serving the dual role is even more attractive. It's often cloudy here, and I probably will be spending time on clusters and doubles with the 80 and the 110 so as to best use my limited viewing time.
Solar viewing would be a fun adjunct, but I may not do it much.
Torn, but probably will go with option 2

Siebert eyepieces

Posted By Stephen Shlafer

Anybody have experience with them? And is there a big improvement over the Maxbright for the price?

More questions

Posted By Stephen Shlafer

I will mostly be viewing the moon, double stars, clusters, nebulae and also some planetary viewing.
My telescopes will be the SV 80 ED f/7, the SV 110 ED f/7, and in about a year an 8" teeter's Dobsonian with Zambuto primary mirror.
I have a Baader moon and skyglow filter.
Would other filters be useful?
I don't plan to photograph, only view.
