"I think this is everything. The good news is that both mounts are REALLY good - there isn't a wrong choice."

You just scratched the surface. I own a Paramount for a few years now and your evaluation of MyT and the SB software is very shallow and inaccurate.  Over years on many different forums, I read many threads which were comparing premium mounts. Quite often someone would recite a well known cliché, you can’t wrong with either one.  I found this very misleading.  Unfortunately, the truth is there is wrong choice.

Thanks Roland. As I saw the AP team heading to dinner tonight, I told George I would be picking his brain tomorrow for a shopping list for this. I See you have given me a parts list already so this should be even easier on George now as I did not see your reply until now.

Erik,
 
I don't think back-focus distance will be a problem on a 160mm scope!  It's when you go with a short focal-length scope you run into back-focus problems.  And at least with the Baader, there's a "secret" way to gain around 3/4" in back-focus distance -- you replace the Baader 2" Click-Lock with Baader T2 threaded fittings.

A Herschel Wedge! Baader or Lunt. I've used them on my AP scopes with great success.  The solar load on a quality refractor is no problem so long as the scope has front lens elements only.  You'll get unbelievable views with your 160 and a wedge. Make sure to get a 2" model and to use additional ND filters for visual. The Baader comes as a kit with everything you need. 

Of course you can only use a wedge with! a refractor!

Re: solar filters

Don Anderson
 

Just for the record, Al Nagler has stated that there is no problem using their NP scopes for solar viewing with a wedge. The rear elements are far enough forward in the light path that there is no heating problem. I can't comment on others such as those from Takahashi.

Pawel,
I'm curious about your comment to keep the Sun centered to prevent heating up the telescope elements.  Unless you've got a 4-element Petzvel design scope where the rear elements are near focus, I don't see two or three elements at the front of the scope where the image is totally unfocused, heating up -- whether centered or not.
 
I'll admit that my little 80mm triplet doesn't transmit nearly as much light and heat as your big aperture scopes, but I've never heated mine up to the point where the wedge was uncomfortable to touch -- even while imaging continuously for 7 hours with an ambient temperature of 98° F. 
 
And I sure don't understand why keeping the sun centered would decrease heat buildup in the telescope lenses.

Definitively the wedge. I have been using it on my AP152 and the views were terrific and I had no issue getting info focus with Canon. Views are better than baader Astrosolar. But if you just want to try, get the filer foil and make yourself a safe filter cell. Costs close to nothing compared to the scope.

One point with wedge - keep the sun centered, otherwise it will heat the telescope elements. You may need to cover the scope from time to time to let the heat trap cool. Just follow the instructions. It is very safe.

Re: solar filters

Pawel,
 
I just thought of how your big scopes can heat up telescope elements -- field flattener.  I believe the image comes to focus in the flattener -- so that would definitely heat the lenses up.
 
I'm not using a flattener at the moment so that's not a problem for me.  And even if it was, I suspect my much smaller 80mm scope still wouldn't heat things up as much.

Yes, it unscrews.  Baader makes a special thin adapter ring that replaces it.  Then you screw standard T2 accessories into that ring.

Do you mean the click lock adapter on the wedge itself?

Hi Woody... you're right on all fronts... ;-)...

I was just being cautious towards potential buyers, to check their systems... I've used the Baader wedge on my AP155... but also on shorter focal lengths of other brands, and then - as you said - you need to work your way around the back-focus problems... ;-)

Erik,
 
I don't think back-focus distance will be a problem on a 160mm scope!  It's when you go with a short focal-length scope you run into back-focus problems.  And at least with the Baader, there's a "secret" way to gain around 3/4" in back-focus distance -- you replace the Baader 2" Click-Lock with Baader T2 threaded fittings.

Hi,

I'd suggest as a (cheaper) still-quite-good alternative:


Two versions: one for visual, one for photography...

The wedges are a bit better, but... be aware of the potential problem of backfocus with the wedges... check your system's focus distances before buying... ;-)

Don't go for glass filters...

A Herschel Wedge! Baader or Lunt. I've used them on my AP scopes with great success.  The solar load on a quality refractor is no problem so long as the scope has front lens elements only.  You'll get unbelievable views with your 160 and a wedge. Make sure to get a 2" model and to use additional ND filters for visual. The Baader comes as a kit with everything you need. 

Of course you can only use a wedge with! a refractor!

For the money a wedge is going to cost versus the amount of use does not
seem a viable alternative.

Mike,



What's this about a wedge not allowing photography? Who/what gave you that
idea?



Of course you can image with a wedge. In fact, Baader makes two versions of
their Herschel Wedge, the "V" version for visual, and the "P" version for
photography. The difference is the "P" version comes with more ND filters.
Cameras can take more brightness than our eyes, so in the "P" version,
Baader includes a couple of less-dense ND filters exclusively for
photography.



I'll even go as far as saying Herschel Wedges are BETTER for imaging. So
far as I know, Herschel Wedges are the best for white-light solar viewing
and imaging. But yes, they're also the most expensive.



Also note that the Baader Herschel Wedges come with the greenish Baader
Continuum filter. You'll have to spend an additional $100 or so to add a
Continuum filter to a Lunt wedge -- which seriously narrows the price
difference between the two brands.



Woody.

Re: solar filters

Rodolphe Pineau <pineau@...>
 

I use to have a glass filter (not on a AP telescope but I don't think this is relevant to the current comparison).
Then I moved to a Lunt solar wedge.
Here are 2 example taken with the same telescope (102 triplet APO):
glass filter imaging : http://www.rti-zone.org/astro/moon_sun/900gto/sun/spots_1582_1579_1575.jpg
Lunt wedge : http://www.rti-zone.org/astro/moon_sun/900gto/sun/Sun_partial_eclipse_2014_10_23_1.png

I think the image speak for themselves.

Re: solar filters

Christopher Erickson
 

Personally I have a Coronado 40mm filter set, a Daystar Quark, a mess of Orion glass filters and a roll of Baader visual film.
 
The Coronado gives the best solar views, followed by the Quark, followed by the glass filters and the film in last place.
 
I have tried a wedge but do not own one.  It seemed about on-par with the glass filters to me.
