Ha filters

without detracting from the thread below about Astrodons (too expensive for me)

7nm baader or 6nm Astronomik?

[Demonperformer]

Or Baader 3.5nm?

More expensive than the 7nm but considerably cheaper than the Astronomik 6nm.

Sorry should of clarified that it be a 1.25 size..

If baader did the 3.5 in a 1.25 size that they been promising for over a year , and with intentions of doing the same in O111..then yeah be high on the list

I did wonder, but I thought it worth mentioning.

I too have been waiting for them to get on with the 1.25 set. My "by gosh & by golly" approximation (based on comparison between this one and their 7nm filters) was that a 3-filter 1.25" set would cost roughly the same as one chroma/astrodon. Wish they'd hurry up!

Glad they were helpful, thank you.  I can't think of anything else that would be useful except for star selection and things you can do with that.  But if I do I'll post some more.

Hi Carole just watched your video and found it very helpful if you can do one on alignment of filters that would be great as I have the same issue my stars just dont overlay at all

I use the 7nm Baader and am very happy with it.

Read this when you do.

I certainly would not choose them due to out of band transmission.
