  1. 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
  2. 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
  3. i can just get this with the screen transfer function
  4. Hey guys I've attached the 16 bit TIFF file (stacked on DSS) Can someone do a brief edit?? Thanks! Orion 2 min.TIF

  6. 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)
  7. 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
  8. 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?
  9. 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
  10. 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)
  11. 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!
  12. Thanks all, very helpful How do I improve from this, my histogram looks way off?
  13. 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 !
  14. 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?
