That's magnificent :) Lovely clear Horsehead and nicely detailed Flame :) What focal length lens?

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 again folks for the kind feedback ...

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.

      Today at 3am (Australia) I woke up and I tried to observe the Orion nebula. It was pretty hard to image it since I don't have a camera adapter and a had 4 second exposures. But after 20 tries I finally got non-wobbly image. The camera could see more than my own eyes!

      Taken on the night of 12 September. 
      NGC6826 - The Blinking Nebula.
      This on Wiki:
      NGC6826 is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "blinking planetary", although many other nebulae exhibit such "blinking". When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding nebula. However, it can be viewed well using averted vision, which causes it to "blink" in and out of view as the observer's eye wanders. A distinctive feature of this nebula are the two bright patches on either side, which are known as Fast Low-Ionization Emission Regions, or FLIERS. They appear to be relatively young, moving outwards at supersonic speeds.
      Right ascension: 19 h 44 m 48.2 s
      Declination: +50° 31′ 30.3″
      Distance: ~2000 ly
      Apparent magnitude (V): 8.8
      Apparent dimensions (V): 27″ × 24″
      Constellation: Cygnus
      Radius: 0.22 x 0.20 ly
      Designations: HD 186924, SAO 31951, Caldwell 15
       
      Equipment: 
      Imaging: C9.25; CGEM (diy hypertuned); ASI385MC; Baader neodymium filter; Astro Photography Tool
      Guiding: Travelscope 70; SSAG; PHD2
      Processing: DSS; Photoshop CS4 Extended 
      99 x 20" lights, of which 63 were stacked; 50 x darks; 50x bias; 50 x flats

      Looks like I'm going to have to have another go at my collimation. Very happy with this even so, as it's the first serious imaging I've done for sooo long! A lot more data is required to bring out the detail in the nebula. 
      Comments/suggestions welcome.

      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.
