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.

Wonderful. Reminds me of the images I used to look at in the Space Encyclopeadia I had in the '60s/'70s that were taken with the Mt Palomar 200" telescope.

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

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... 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.

      I managed to get some time to process another of my images exposed in January/February 2020.
      This was the last image when my USB port on my Astro40D failed. This happened while imaging this scene but it happened toward the end of the imaging plan so I got almost the subs that I wanted. The total exposure time was 16 hours and 16 minutes in ISO1600 for all of the subs, RGB, (OSC through the UV/IR Cut filter), HAlpha and OIII.
      Imaged through my 8" SCT at f6.3, 1280mm FL.

      Messier 57 is is just coming into a position for a decent look around 11 30 pm. IT is a colourful object and I thought it would give me a good target with which to practice my colour developing in PS/Lightroom. I have read so much about how to produce a LRGB image from the four stacked/calibrated luminance, red, blue and green images,  a lot seems contradicatory and some, when followed, gave me colour yes, but not as we know it. I am sure a fair chunk must be put down to me. Anyway, I now have a work flow which gives me colour, sometimes resembling what other people have obtained. Progess of sorts.
      This images is based on 114s subs at gain 139, offset 21.
      L 39, R 20, G 20, B 19
      Calibrated  and stacked in DSS (flats, dark flats and darks)
      Messier 57 Ring Nebula in Lyra
       

      NASA: M57, or the Ring Nebula, is a planetary nebula, the glowing remains of a sun-like star. The tiny white dot in the centre of the nebula is the star’s hot core, called a white dwarf. M57 is about 2,000 light-years away in the constellation Lyra, and is best observed during August. Discovered by the French astronomer Antoine Darquier de Pellepoix in 1779, the Ring Nebula has an apparent magnitude of 8.8 and can be spotted with moderately sized telescopes.
      Equipment: Celestron 9.25 XLT at F10,  Skywatcher EQ6 Pro GEM, ZWO 1600MM Pro, ZWO EFW with ZWO LRGB filters, QHY5IIC guide camera on Skywatcher 9 x 50 finderscope, Celestron Focus Motor
      Software: Ascom 6, Eqmod, Cartes du Ciel, AstroPhotography Tool, PHD2

      Since I am very new to this, I struggle a lot. Especially when observing planets and also recently deep sky objects. My telescope is an amateur telescope and its almost 11 years old (The telescope was re used a year ago). During summer of last year I took photos of Saturn,Jupiter and a month ago took photos of Venus and Mars. About 2 days ago I stumbled upon a new thing in the sky, (Unfortunately, I didn't take a picture). It definitely was in the Orion constellation  as I had observed Betelgeuse and the 3 stars that were close to each other. After a couple of minutes later I saw 2 stars next to each other and another two which were on top of the other star, surrounding these set of stars were a blue-ish and grey-ish colour at the same time. I had done some research and many people told me it was the trapezium cluster found in Orion. I honestly don't know. Any ideas? Thanks.
