Deep Sky Astrophotography (Gear Discussion)

hello guys i need your help . I m using a canon 500 f4 IS I and i m looking for filter to shoot under light pollution. I readed we can find some filters to fit in the drop filter of big white, like the IDAS LPS-V4 . it s hard to find information about it. Can you confirm ant tell me what size to buy, 52mm i guess. Any idea where i can buy this? a picture of the filter in the drop filter would be great. I barely undertand how to install it, according to the pictures of the filter i see on the web

I use the 52mm IDAS LPS-P2 with very good results.

ok thanks but how to you install it? is it not a spin-on filter?

Yes it is. The filter unscrews from the frame (at least it does on the ones I have). Did you buy the lens are are you renting/borrowing it? I believe both my 400mm and 300mm lenses came with a spare (it was long enough ago that I could be mistaken). I also have one that can be rotated from the outside for use with a CP.

You very likely need one of these Drop in filter holders.

Also which Samyangs do you plan to get, maybe you should wait until the reviews of the Sigma 20mm Art

No the Sigma 20 mm 1.4 Art is not good for astrophotograpy, see here : http://www.lenstip.com/457.7-Lens_review-Sigma_A_20_mm_f_1.4_DG_HSM_Coma__astigmatism_and_bokeh.html

I bought an extra drop in filter holder used (didn't care about the quality or the glass)..not the screw on. The problem is most filters are.too thick to fit back into the camera. I bought the one with the flip up gel holder. There is a retainer ring that holds the glass filter in. I just swapped it with my deep.sky filter. Works like a champ.
