Hi all I have a Astronomik CLS filter for my astro-modified DSLR. It's definitely useful for DSO imaging in Bortle 5/6 skies But would you use it in Bortle 3/4 skies? Or would you recommend imaging without it? Thanks

Thanks so much guys, and for breaking down how you did it. very helpful! Happy with the outcome No it's just a CLS filter, not H-alpha

i can just get this with the screen transfer function

Hey guys I've attached the 16 bit TIFF file (stacked on DSS) Can someone do a brief edit?? Thanks! Orion 2 min.TIF

Hey thanks, sorry how I do that? I processed them on PixInsight, now I have 3 separate files - Master bias, dark and light files (.xisf)

Hi all! Could someone do a quick processing of this image I took, on PixInsight? I just want an idea what I can get out of it... Many thanks! masterLight_BIN-1_EXPOSURE-121.00s_FILTER-NoFilter_Mono.xisf

https://www.highpointscientific.com/astronomik-cls-canon-eos-xt-clip-filter-cls-eos-xt On this website it says this filter is designed for use with lenses of all apertures, operating at f/3 and above does this mean I can't use it for my canon 50mm f/1.8 lens?

Amazing thanks!

Does anyone have an automatic workflow on PixInsight I wanted to quickly run it on my image to see what comes up? masterLight_BIN-1_EXPOSURE-91.00s_FILTER-NoFilter_Mono.xisf

Hi guys thanks for your advice can I just check my 550d is astro-modified (rear filter removed) so is this the one to go for -> Clip filter for Canon EOS APS-C £116 (https://www.firstlightoptics.com/light-pollution-reduction/astronomik-cls-filter.html)

Hi all I'm looking for a budget light filter so I can start using my set up in my back garden I'm using an astro-modified Canon 550d + Canon 50mm F/1.8 lens on a star tracker. I'm in Bortle Class 5 skies. Any advice for this? Thanks!

Thanks all, very helpful How do I improve from this, my histogram looks way off?

Hi all! Happy weekend I'm a beginner, hoping to get some good shots today I have an astro modified Canon 550d on Sky-Watcher star adventurer tracker & Canon 50mm f/1.8 lens, Bortle 4 sky Any suggestions for my camera ISO and exposure length? Would you suggest ISO 800, or higher? Thanks !

thanks i will next give it a go without the filter. and will give it a clean as well. do you think I need longer exposures, if so how long?

new filter, have cleaned it now, but waiting for next clear skies 😛 thx

Hello all, I took a wide field shot of Orion few nights ago. My set up: Astro-modified Canon 550d, Canon 50mm F/18 STM lens, Svbony CLS clip filter in Bortle 5 skies. ISO 800, F/2.8, exposure 1 min x 40. I'm not very happy with the result. Unsure why there is so much flare with the brighter stars and I didn't seem to get enough detail out of the nebula either Any advice on how I can improve for next time? I do understand I need to take longer exposures. Do I need a different filter? thanks! Orion 11-02-21.TIF

Hey are you able to bring anything much out of this shot of Rosette I took? Again I think maybe my exposure time was not long enough. it's 1.5min shots x 20 Rosette 1.5 min.tif

That's really sound advice Thanks so much. Yes I am planning on moving to a larger lens, but wanted to get bit better at taking wide field shots. This flares hasn't happened on my previous images, so it might be my CLS filter...

Hey man, awesome thanks What is causing these flares? was it a smudge on my lens? Also this was my set-up: Astro-modified Canon 550d, Svbony CLS filter, Canon 50mm lens f/1.8 STM, Bortle sky 5 ISO 800, f/2.8, 1 min exposures x 40 Any suggestions on how I can improve to capture more detail and colour?

Anyone wanna try processing this? thx Orion 11-02-21.TIF

Hi all, Took a shot of Orion last night, with a Canon 50mm lens I've got PixInsight, but can't seem to get much out of the image... anyone fancy a try with editing?? I've attached the stacked picture Orion 11-02-21.TIF

camera lens did end up misting.... 😛 but still got a some decent shots I think

ok will post, might need some help with processing. btw, do I take the flat frames with the CLS filter on?

yup I've got a intervalometer. ok I'm going to use ISO 800, f/2.8, 1 min exposure x 30.
