Comet PANSTARRS thru IDAS EAO1

This was the good test sample with IDAS EAO1 filter. C/2017T2 was located to NW from my backyard, which is exactly toward LA basin – Bortle class 8-9. So very tough situations. I tried that.

BORG 107FL F6 + ASI183MC + IDAS EAO1, 10 x 150″

I couldn’t see anything in preview mode. So I wasn’t sure at all the scope was pointing to the right direction. But I went for it without the confidence. I’m pleased to find it out after the image processing. The comet is really faint or the background is so bright.

I didn’t compare with a filter and without. But I’m quite sure a filter helps a lot. After processing, I thought I should have extended the exposure time.

Anyway, a filter capture the comet’s C2 lines as designed while blocking light pollution as much as possible.

  1. Hi Ted. Looks promising! In the suburbs, we need all the help we can get… Are you selling these yet? Did not see them on your website. Can you bring some to NEAF?

    • Keith, thanks. yes, it works well as designed. It will come in stock middle of next month. So I’m sure I can bring to NEAF.
