Planetary filters

[dan_uk]

Does anyone have much experience with planetary filters?

I find Jupiter too bright to discern any details even with the Baader neodymium filter.

I've considered the Televue planetary filter, a variable polarizer, and an 82a or 80a wratten.

Also has anyone used the Baader set of colored filters? Are they worth it?

Thanks,

Daniel

You could try stacking a Moon/light blue filter with the Baader if Jupiter is too bright, I take it you are using a Newtonian? Personally I really like the neodymium filter, I'd love to try the TV number though

Are you talking visual .

Using a 12" Schmidt Cassegrain, the neodymium does help but it's still too bright to discern details.

I've bought a 25% ND filter to try out for now.

This is purely for visual.

I was also recommended a wratten 82a but I was wondering how those compare to a the baader light blue equivalent?

what telescope is it? A meade lx?

I find that like the moon if you just allow your eyes time to adjust then the detail starts to appear as your pupil shrinks. to start to see real detail I find about half an hour of continued viewing works best on Jupiter.

I think its a 14" sct

Why not wear sunglasses :-)

Hah I'm not that crazy knobby, it's a 12" LX.

Does anyone know where I can find a conversion chart of wratten # to wavelength in Nm? Specifically 80a and 82a

I did have similar trouble in my Meade LS8 so I added the neutral density filter to the neodymium,and it seemed to work, Maybe the high mag didnt help because when I used the neodymium in my SW 120St it worked a treat

[dan_uk]

Which ND filter did you use? I have the 25% one on the way to try out

Let us know how the 25% turns out. I've been having similar thoughts about the baarder set of coloureds. Will observe this thread with interest.

That said,I had some great viewing of Jupiter as the mist rolled in the other night. Looks like nature got the filter just about right!

I have just come across this conversion info for your Wratten to Nm question. Scroll to the bottom to get passed the IR guff.

I'm no expert on this - Hope that this helps.

Unfortunately it doesn't include the wratten numbers I'm after, been searching around all weekend. I know the Baaders are slightly off the wratten scale and considering the quality of their products I might just assume Baader know what they're doing and buy them

An 82A wratten filter at 73% transmission will be ~

I ended up purchasing the Baader colour filter set, I will let you all know how they are once I receive them.

I wasn't able to really compare the standard wrattens to the Baaders but going on past experience with Baader i'm sure they will work well.

[dan_uk]

Never did mention how these were! Really high quality as you'd expect from Baader, really can notice the difference with cheaper wratten filters. Unfortunately I found that colour filters didn't help me so much but I admit I don't spend enough time at the eyepiece on individual objects so I wouldn't be the best person to review these

Which Baader filters are you talking about?
