To use or not to use an Astromomik CLS clip in filter on the Heart Nebula?

Recommended Posts

Hi guys, I'm planning on an i.aging session Wednesday.  I have a modified Canon 600D attached to a Zenithstar 61. My darksite is bortle 3 ( lovely dark skies with next to no light pollution) I can achieve 2 mins exposures on a little star adventurer. SO my question is, will it be worth shooting in rgb & with the CLS filter. Ideally i require a ha12nm filter, however currently I dont own one.  

Or shall I wait until next year and aim for the pinwheel galaxy?

Much appreciated👍🏼

It'll be worth shooting but I wouldn't use the cls filter. It is a light pollution filter and in bortle 3 skies I've been able to do 5 min subs without it being over exposed using ISO 800, so you should be perfectly fine with 2 min subs.

Hi pal, 

Thanks for your reply. I was wondering if the cls filter would improve contrast. Watching astrobackyard, trevor uses an ha12nm filter to create a luminance layer.  I was thinking maybe the cls would help with contrast (obviously not as well as an ha filter). Would you think it would be worth doing a set of rgbs and another ser with the cls filter, or just shoot totally in rgb?

Thanks again👍🏼

I used a CLS filter for a while but I think it just takes all the life out of the image... my R channels get very noisy. Now I remove the LP gradient in software.

You're shooting RGB with a DSLR?

I see, maybe I will leave it in the case. I dont fancy making processing more tricky. I mean imaging in colour😂 

Thanks for your help👍🏼
