small achromats and fringe/violet filters

Posted By Kurt Endres

I have the Baader contrast booster and was very disappointed with it. To be fair though I used it in a Stellarvue Nighthawk which is already well corrected. The image I got was just yellow with no added contrast. Maybe it works better in achromats that aren't as well corrected.

TMB 105 LW vs SV-105 vs Tak FS-102II

Posted By Kurt Endres

Dave, have you considered the f/8.8 SV102BV? I have the f/7.75 SV102ABV and It's an excellent scope. Both are optimized for regular and Binoviewing.

I don't know how many of these Vic has left as he is planing on discontinuing them.

Foam vs Knife-Edge Baffles

Posted By Kurt Endres

I just look at it this way... AP,Tak,SV,TEC and TMB all use Knife edge baffling. Must be a reason why?

65mm .. seriously

Posted By Kurt Endres

With the bino's you're limited to that magnification. Also, how much terrestrial viewing can you do with a dob?

UO Orthos not as good?

Posted By Kurt Endres

My Ortho's work extremely well in my scopes but I am curious to see exactly how much better the TV plossl line is.

Roland,

Could you possibly tell me how these might compare to the Celestron Ultima (japan version)9x63? I find the Ultima's to be very good, but there's a slight amount of flaring towards the edge. What differences might I see with yours?

Finally! something that has Astro-physics printed on it that I can afford.... LOL. smile

Hello, all.

Here is a montage of 5 images taken with my Nikon D-70 and an 18 mm lens. This was taken in Black Mesa State Park in the Oklahoma panhandle. A single inextingushable sodium vapor light illuminates the landscape at both ends of the nearly 180° span of the image. Thanks for looking.

Steve

That's a beautiful shot!

If you had to buy one eyepiece????

Posted By Kurt Endres

In that price range, I'd probably go with the 17mm Nagler. The 35mm Pan would be nice, but it would have too much (8.8mm) exit pupil.

OK. I'm going to be a pain and put this kind of question to the forum. With my limited experience making this kinda of choice is very difficult. Here's the story the weekend after Thanksgiving me and a couple of friends have a tirp planned to Cherry Springs State Park in Pennsylvania. This will be for all of us our first true look ever at a dark sky. Basically it's the closest black spot on the light pollution map to Long Island New York. So I'm thinking of treating myself to my first high quality eyepiece (300-400 range) I mostly go for deepspace objects and Nebula, but when the planets are up I always take a look. I wear glasses but I find with the Plossls I'm always taking them off and it's no big deal and with the new JMI coming it's easy for another user to refocus.

This is what I have:

LXD75 10" Schmidt-Newt w/UHTC (f/4) Focal lenght 1012mm
Meade 4000 series Plossl eyepiece set
New EV1NM coming from JMI.
2x and 3x Televue Barlow

The eyepieces are OK but from what I've been told this kind of fast scope really does not like Plossl eyepieces.

So what would you recommend? What would be ideal for this kind of fast scope and my budget range?

Thanks Chris

Orthos in binoviewer

Will 4mm Ortho (volcano top) work well in a binoviewer, or is the eye relief too tight? (It doesn't bother me with one eye.)

Dmitri

I have the complete set with doubles in the 25,18,12.5 and 7mm lengths. The 7mm has worked just fine. I'd say that if you can get them to align with your eyes, then they'll work for you. Although, as you stated, the ER is quite tight.
