Sky Watcher O-III filter - any good for imaging?

Recommended Posts

Hi

I want to improve my imaging of DSOs (I struggle a lot with LP) - particularly the Veil. 

But the price of O-III filters looks pretty steep to me.  Except this one: http://www.365astronomy.com/SkyWatcher-O-III-Filter-2.html

Would that be any help to me? 

Steve

      A friend ask me about filter size, I already had a Excel sheet with that calculation. But I did a new web calculator.
      It's the first version but it looks to calculate it correct, have a look:
      http://www.astrofriend.eu/astronomy/astronomy-calculations/minimize-vignetting/minimize-vignetting.html
      It's not any high precision calculation, but gives knowledge enough I think.
      Too small filter gives vignetting, too big filter empty the wallet.

      The weather has been so bad I have had the time to finish a video on using astro filters with the Nikon Z bodies and Nikon camera lenses. There is a manual alternative to the FTZ allowing 1.25 inch filters to be fitted between camera and F-mount lenses, and for some lenses and end of lens solution make sense. FAstroTZ is described here:

      I found this setup in internet and make me think, with AZEQ6 GT and 2 scopes, different weights and size, without counterweight in AZ mode! 
      - I can put a MAK100mm 3kg +- and a OO VX10l  12kg +- without counterweight?
       
      Does anyone have this setup mount and already used without counterweight with two telescopes of different weights? Is it really necessary to have a balance using in AZ mode?
      The problem to centralize the object with both scopes is true? With the SW AZEQ6 GT?
      Follow the images
      a TSA-120 with 6.5 kg i think and the other with 22kg i forgot the brand hehe you can help me?

      Hi,
      I'm working with some recent data of a new(ish) camera, and my Ha data is pretty good, but the oiii has these strange artifacts around the borders.
      If I use any kind of local normalization then it pretty much ruins most of the image, as you can see below..
      First the Ha:

       
      Oiii with local normalization:

       
      oiii local normalization map, see how it fits with the artifacts:

       
      Oiii without any local normalization:

       
      These edge artifacts, could they be related to a bad filter or is it a processing artifact, has anyone seen anything similar?
       
      I am using Astro Pixel Processor for calibration and stacking.. Im kind of stumped on this one, and I am going to yank out the Oiii filter this weekend to have a looksie.

      Following a filter size upgrade I have an Astronomik LRGB set of filters, 1 1/4 inch. Probably around 12 years old. Kept in a filterwheel when in use but they have also been stored for a couple of years in their original box when I acquired some Baader ones to match my Baader narrowband filters. No scratches or coating issues. I have tried to show this in the images attached. 
      Looking for £80 posted given their age.
