Removing the Baader Filter new
      #5592235 - 12/28/12 07:59 AM

I was thinking about removing the Baader filter actually leaving the camera without any filter.

Is it feasible to shoot in these conditions or is there any side effect?

Thanks, regards,
RC

Short answer is yes, there is a side effect. You don't want ALL Ha light coming through, it will cause soft pictures with very bloated stars.

Ok. Thanks for the reply.
I'll go through by a 60DA, probably.
I need to make a step in quality and I cannot live with this halos and noise that my 1000D is producing.

Best Regards,
RC

I have the 450d modded with the Astronomik clear glass replacement, I don't have issues with Halos but I do have issues with reflections, likely from my MPCC.

Check the thread mentioned earlier. People who have simply removed the stock IR filter and not replaced it are observing star bloat caused by IR leakage through the front filter used for the dust cleaner function. There is no disadvantage of having the Baader filter in place unless you want to shoot IR photography. Also, removing it without repositioning the sensor platform accurately will render your camera unable to focus to infinity with normal lenses. It will also make it unable to shoot daylight images with a custom white balance.

The 60Da allows less HA to pass through than a modified DSLR.

You're currently experiencing halos around your stars with a modified DSLR with both filters in place?

This is my question...are BOTH filters installed? Stock LPF-1, and the Baader, or JUST the Baader??

And yes, the 60Da is not going to perform as well as a modified camera, though it has proven itself to be quite capable for imaging..
