Hi all.
I am presently looking to purchase a set of narrowband filters. My preference is leaning towards a set a Baader's. I cannot justify the cost of astronomic filters, so leaves me in the Optalong, Baader, and Altair Astro camp. Has anybody used altair Astro narrowband filters? Are they any good. Their price is higher than the Baader's, are they worth the extra cash? What are Optalong narrowband filters like to use? Again, a set of these come in more than the Baader's.
Any advice from the Stargazers community would be greatly appreciated.
Thank you.

Hi, just seen this post. You could go down the route of a filter draw and 1.25 holder. Or buy the zwo efw mini filter wheel and connect this directly to the camera body, no spacers between the two, this would enable you to use 1.25" filters without suffering vignetting. The only thing I would comment on here is to buy some of the delcrin spacers from FLO, placing the thinnest between the filter wheel and the camera body, thus enabling you to unscrew them easily once finished. You would still need to take the remaining distance with you spacers to get to the 55mm distance. Hope this helps?
regards.

Thank you for the link, I had a good look at your images, they are very impressive. Had a good look around on interest, I cannot find much about these filters, review wise. I think I will give Altair a ring.
Thanks
