IC1340 - first use of Svbony EOS CLS Filter

[Dazzyt66]

Taken from my bortle 7/8 back garden when there was a brief break in the clouds last night - I really just wanted to see how much difference the CLS filter made. Taken with 200mm prime lens at f16! (yes, stupidly I turned the aperture the wrong way as I was in such a rush!!)

This is just 20x30s lights (best 16 used), iso1600, 20 Darks, 40 Flats stacked in DSS (for a change!), processed in StarTools and final tweaks in Gimp.

I know its a bit rubbish and slightly out of focus but it bodes well for my filter when I can do longer sessions with the right settings!! 

I only imaged it cos that's where the break in the clouds were and when I saw 'supernova remnant' I couldn't resist!

Weather has been rubbish so I practiced my StarTools skills and reprocessed to this - and I'm quite happy with this considering where it started! 🤣

Very impressed with the reprocessing,  what did you do differently?

Thanks! I was impressed with how it changed just by tweaks here and there.

I mainly used the mask in different ways - firstly to bring out the colour in the nebulosity (after getting sampled colouring from the stars rather than let ST do its thing globally). I then used the mask again to de-fringe and dim the stars and then eased off on the noise reduction. It was a mix from about 4 different Youtube ST tutorials. Good use of bad weather!

Good to see examples of this filter being used and 30 second exposures, coupled with f16 it shows I shouldn't rule this filter out with even shorter exposure potential.

Having never used a filter before and not being sure how much it would be of use now that LED seems to be taking over the world I was really impressed with the difference - takes my garden viewing to a different level. I'm hoping additional use at different settings will be super impressive! And it was only £60! 🤞

I have a little EOS CLS clip-filter in some kit I bought from a friend, always been using the HA filter but will have to give the CLS a go.

Yeah, its the clip in version I'm using. Really pleased with it!

Had another go at it last night with my 135mm at f4. Due to cloud was only able to get 6 viable 30s subs but even with that the nebulosity is becoming apparent:
