solar filters

Curious as to what solar filters folks have found to be good...I was thinking of a Thousand Oaks glass filter for the 160 EDF...anyone have one for use with this scope...what size fits properly...?

Already, in the gathering dusk, a few of the stars are turning on their lights.

Vega, the brightest one, is now dropping towards the west.  Can it be half

a year since I watched her April rising in the east?  Low in the southwest

Antares blinks a sad farwell to fall...

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!

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...

Erik.

Good point on the backfocus. Both my AP155 and 130 GTO have plenty of backfocus for my 2" Baader wedge. My previous AP130 f6 also had plenty of backfocus. TeleVue scopes I've had in the past did not have have enough backfocus for a 2" wedge but we're fine for a 1.25" one. Personally, I wouldn't use a 1.25" wedge with more that 4" of aperture.

My Baader Herschel Wedge focuses on my Traveler, and have imaged with it.


Stuart Heggie <stuart.j.heggie@...>
 

I was going to chime in as well saying that the Herschel wedge from Baader focused fine on my AP130EDT (same should be true for the 155EDF) and it comes in two forms one of which is 'P' i.e. Photographic. You need to be sure to get that one else it is just visual.

Huh? There is nothing better in my opinion. Really. The Baader Herschel Wedge is THE solar accessory for white light and Ca imaging.

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.

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.

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.

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.

For the money a wedge is going to cost versus the amount of use does not

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... ;-)

Trying to come to focus with the Baader wedge and my ZWO/NW127is now. Think I'm about 2-3 mm away for prime focus. Can get there (barely) with my 2.5 and 5x PowerMates.

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!

Again, by replacing the Baader 2" Click-Lock with their T2 threaded adapters, you can gain almost 3/4" (~19mm) of back focus.
 
I've got my Baader on an 80mm triplet refractor and can reach focus prime, and with 2x and 3x Barlows with my C-mount camera.  For eyepieces, you can also use the Astrosystems ultra low-profile 2" to 1.25" adapter which doesn't have an external thumbscrew, but an internal setscrew.  This lets you slip eyepieces and Barlows deeper into the 2" Baader Click-Lock holder by as much as an inch.

Trying to come to focus with the Baader wedge and my ZWO/NW127is now. Think I'm about 2-3 mm away for prime focus. Can get there (barely) with my 2.5 and 5x PowerMates.

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.

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

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.
 
Woody
