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.

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.

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.

Re: solar filters

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.

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.

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!

extending Keypad Serial cable CABK9S15

Lee
 

I realize most of the A-P crew is at NEAF but I thought I would try this question here in case they check in.  


Setting up my AP1600GTO-AE. I want to run the serial cable about 25ft from the GTOCP3 keypad connector to the computer.  


Is there a 25ft version of the keypad receptacle cable?


Alternately,  can I connect the 15ft CABSER15 that I am not using on the AE serial port (since I replaced it with a 25ft cable) as an extension of the keypad cable.  Other than the connectors won’t secure to each other without a coupler, is there any problem extending the keypad serial cable with the CABSER15?

 

I will put a coupler in between them to be sure the connection is secure since I am fishing the serial line through a conduit.


Thoughts appreciated. 


Lee



SkyX Pro and Windows 10 and Mach 1

Hi,


Newbie here...


I have a Mach 1 running with CP3 and a USB-Serial interface to a Dell with Windows 10. I've got an active com port and can control the mount with SkyX Pro. I am trying to get the Ascom interface working, so I've got .net current, the 6.2 platform installed, the V2X driver installed and just downloaded and installed the Ascom 2X Mount Adapter from Software Bisque.


Problem: I can't find the V2X Mount in the choose dialog, so I still have my non-Ascom interface.


Ideas?


Thanks - Doug
