Thanks for positive feedback folks...

What focal length lens?

Gina...thanks, it's an 800mm ...I think around 1280mm equivalent on the 60Da

Lovely image. Is the diffraction pattern lens induced or added during PP?

Bob.

Bob ...thanks, most older lenses produce diffraction spikes but the new lenses now tend to have rounded diaphragms designed to reduce this effect and improved the bokeh for daylight photographers.

Wowsers! Stunning! I would also love to know what mout you had for 600 second subs,

Really beautiful!

Sent from my laptop because I don't want to end up with arthritic thumbs and I hate being on call 24/7 so I refuse to carry one of these so called Smart Phones. So named becauase they are smarter than their owners!

Sorry - was that too bitchy? :evil:

Thanks again folks for the kind feedback ...

Cracking result Mike. Out of interest, what decided you to go for f7 over wide open or one stop down? It has certainly worked.

Dave

Thanks... it was just a balance between closing the diaphragm enough to produce diffraction spikes while keeping star images tight ...& enough light to keep exposures 600secs maximum because of possible noise build up, f8 would only have tightened the star images slightly more.

Thanks...it's an AP1200 on field tripod but also autoguide with an SBIG STV through a Takahashi FS-60C anyway to be certain there will be no egg shaped stars.

      The Carina Nebula is a large complex area of bright and dark nebulosity in the constellation Carina. It is located in the Carina–Sagittarius Arm, about 8,500 light-years from Earth. Pro Dataset @telescope.live Telescope: ASA 500N Focal Length: 1900 mm Mount: ASA DDM85 Camera: FLI PL 16803 H-Alpha: 3x600s OIII: 3x600s Bicolour Processing: Pixinsight

      Not sure what topic to put this in but I've been struggling with deep sky stacker, because of my optlong ccd light pollution filter most nebulas come out one shade of red, for example the Monkey's head nebula, see attached example. Dumbell and ring turned out as seen online and Stellarium. All 3 images were taken with a rct f/8 and a canon 600DA. I've never tried these objects without the filter as I got new equipment and this is the most active I've been in my hobby for many years. I'm not spending hundreds or thousands on software so preferably if i can get the correct colour on these with dss or some other free/semi free software that would be great. Thanks

      This is NGC3603 and NGC3576 (AKA The "Statue of Liberty" nebula), a massive H-Alpha region containing a very compact open cluster, located in the constellation "Carina" about 20,000LY away.
      I took this photo during two nights, 14th and 15th March 2021. Imaged using a active cooled and full spectrum modded Canon 40D DSLR attached to a 80mm f6.25 refractor on a CGEM equatorial mount.
      Total exposure time was 3 Hours and 31 minutes in natural color through UV/IR Cut filtered subs from a semi rural sky.
      RGB: 19x60s, 19x120s, 18x180s and 20x300s subs @ ISO1600.

      The 6th January was clear and still and so at last a good night for imaging (not perfect as Moon was still waning).
      My 8" SW 200P Reflector was wanting to be used and so it was carefully mounted onto the HEQ5 and payload maxed out with the imaging train.
      Yeah I know - this combination is a big ask for the job (but an EQ6 is beyond me at the moment!). Anyway with careful balancing and hardly any wind it was worth trying!
      Nebula were best targets and again new ones for me.
      These were the Bubble Nebula, Cave Nebula and Monkey Head Nebula. The Optolong L-eNhance Dual Narrowband Filter was used for all images.
      Usual calibration frames and dithered instead of Dark's. Other 'Astro Stuff' is in my signature. 
      Any constructive criticism's welcome.

      Images:
      Bubble Nebula (Sharpless 162) 15x240secs (1 hour of data).
      Cave Nebula (Sh2-155) 7x240secs & 23x300secs (2hrs 23 mins).
      Monkey Head Nebula (NGC 2174) 44x240secs (just under 3hrs).
