Re: Lunt 60 DS -> Lunt 100 DS

Thank you again GUS. I have I think the last question: How does the 60 DS performs in comparison (brightness, resolution and contrast) to the 100 DSII + circular polarizer? Because apparently, if the polarizer suppresses the glow, the image should remain with black background, with the resolution of...

Re: Lunt 60 DS -> Lunt 100 DS

Thank you very very much GUS, actually I'm really undecided. I know that 100mm will provide much more resolution, but I seriously love the contrast of the 60 DS. The problem is that I can't keep both telescopes due to money, so I have to decide. An idea could be taking the 100 SS and mounting for th...

Re: Lunt 60 DS -> Lunt 100 DS

Point is that the DSII unit should increase the contrast instead of decreasing it. But I don't know how much it will increase the contrast in comparison to the 60 DS (which already has a contrast that I really love). I don't even know how much ghost there will be (but I can go and try it, even if th...

Lunt 60 DS -> Lunt 100 DS

Hello, I write because I'm considering an upgrade from my Lunt 60 double stacked with a Solarmax 60 type front etalon, to a Lunt 100 DSII which I could have at a good price. I know that the views (I'll do 95% visual) in the Lunt 100 DSII will be better, but I don't know if they are so better to wort...

Re: Lunt 60 SS/DS or Lunt 80 SS/DS?

After one month and a half I've reached my final setup. I've found a great offer and I've bought 2 Solarmax 60 front etalons, 1 type I and 1 type II. I've tried both in double stack on my Lunt 60 and I've tried also the triple stack. These are the 4 configurations: http://s6.postimg.org/dmbc0oae5/Co...

Re: Lunt 60 SS/DS or Lunt 80 SS/DS?

So, I have news. I thought that spending money now on a Lunt 80 and then on a DSII (which is hard to find second hand, and however not so cheap), it's too much money for me. So I have seen an offer and I have decided to buy 2 front Solarmax 60 (one is type I and the other is type II) and a BF 15. I'...

Re: Lunt 60 SS/DS or Lunt 80 SS/DS?

OK, me too I really love double stack systems, so I've decided to go that way with my Lunt 60. At the end I've purchased 2 used Solarmax 60 front etalons, one it's type I and the other is type II. I'll try both the front etalons (and also the triple stack) and decide which is better. Thank you very ...

Re: Lunt 60 SS/DS or Lunt 80 SS/DS?

OK I'm about to buy a second hand Solarmax 60 front etalon to DS my Lunt 60. I can have it for a serious lower price than the Lunt 80, and also than the Lunt 60 DS front etalon, so for the moment I think I'll choose that solution, in the future when the budget will allow I'll think about a wider ape...

Re: Lunt 60 SS/DS or Lunt 80 SS/DS?

Ciao Valery! Yes, the Coronado SM90 front etalon would be just perfect, in that case the problem for the moment it's budget. Because the Lunt 80 would be a used one at an affordable price, but the SM90 it's very difficult to find in the used market. I'm still undecided between the Lunt 80 and a DS u...

Re: Lunt 60 SS/DS or Lunt 80 SS/DS?

Uhm, it seems a hard choice, for exemple GUS' post pushes me toward the 80 with a future DSII (also because I would like binoviewing), but Bill's post pushes me toward I don't know if the 60 DS or the 80 SS. I would like to have the possibility to see through a Lunt 80 DSII but I don't know anyone w...

Re: Lunt 60 SS/DS or Lunt 80 SS/DS?

Hi Bill!! Why the DSII didn't work out for you? Because that's my main fear: in the future I really would have a DS telescope, but is it sure that waiting and then spending money for the 80 DSII will worth it? Sincerely I've heard so many discordant opinions on the 80 DSII (versus so many enthusiast...

Ciao Marcello!!! Thank you for your answer, I really hope that we'll meet at the italian solarparty, even if from Florence it takes almost 4 hours by car! I'm seriously considering the 80, for the moment SS and in the future DS. My doubts are coming from the reviews of the DSII for the 80, which see...

Re: Lunt 60 SS/DS or Lunt 80 SS/DS?

Thank you very much for your explication Alexandra! :)

So at the end of the story, upgrading now the Lunt 60 SS with the Lunt 80 SS (with the possibility to DS it in the future) could be a correct choice?

So the visual difference between a Lunt 60 DS and a Lunt 80 DS would be significant?

Re: Lunt 60 SS/DS or Lunt 80 SS/DS?

Thank you all!!! I've already observed with a DS system and I know that that's the way to go. In particular I've observed with a Daystar Quark on my Lunt 60 and with a spectacular Lunt 100 DS. My question is if at the end I could enjoy more the 60 DS or the 80 DS, since it's true that 80 mm is a lit...

The answer "both" would be too easy :D
No, between those two I prefer full disk views. With the possibility to close up until physics allows.

Re: Lunt 60 SS/DS or Lunt 80 SS/DS?

Thank you! ;) But do you think that 20mm more in aperture would beat all the other disadvantages? Reading online it seems to me that the Lunt 80 SS has a more even field than the Lunt 60 SS, but that the Lunt 60 DS has a more even field than the Lunt 80 DS. And, if I put also the polarizer on the 80...

Re: Quark DS : possible?

Mmh, a double Quark combo would give a 17,64X factor over the original focal lenght, i.e. more than 7.000mm on the little PST.
I think it would be really too much.

Hello everyone, I'm a stellar (Sun and other stars) observer from Florence (Italy) and this is my first post here in this wonderful forum :) I started with the super classic PST and one year ago I moved to a Lunt 60 SS / PT / FT / BF 1200. With the latter the views are amazing!!! Now I have the oppo...
