To celebrate the 25th anniversary of Sir Patrick's DSO catalogue, I've added the available Caldwells to my basic Marathon search sequence. 

Those interested may be pleasantly surprised by how many of the additional treasures are only a short hop from a given (or en route to the next) Messier.

The sequence for 40°N can be found at the SEDS Messier Marathon homepage or at my blog.

Peace, Stephen

      After a 20 year long hiatus - my last astrophoto was captured with a film camera in 1997 - at the beginning of 2020 I decided it was time to start again.
      So, January 25th 2020 I brought home my used Sky-Watcher NEQ6 Pro and I immediately started taking photos. Obviously, my first target was M42 in Orion.
      This was my first digital astrophotography. 31 subframes, 30s each, taken at ISO800 with my unmodified Nikon D90, Nikkor 70-300mm at 300mm f/6.3 - January 28th, 2020, home front yard, Bortle 5/6 sky, no guiding, no filters. A grand total of 15.5 minutes...

      A couple of weeks later, me and my wife went to spend Valentine's weekend in the mountains. Of course I couldn't avoid taking advantage of the Bortle 4 sky and I took all my gear with me. Same target, 52 subframes, 45s each, taken at ISO800 with my unmodified Nikon D90, Nikkor 70-300mm at 300m f/5.6 - February 14th, 2020, Tonadico, Bortle 4 sky, no guiding, no filters. 39 minutes total integration.

      After I finished post-processing the second photograph, I was so happy with the result. It felt amazing that I was able to capture so many details and more nebulosity compared to the photo taken from home.
      Months passed, gear was changed. First one being the camera: at the end of February I bought a Nikon D5300 and a couple of months later I astromodified it on my own, adding a UV/IR cut filter in front of the sensor, after cutting it to size.
      In October the rest of the setup finally arrived: Tecnosky 80/480 APO FPL53 Triplet OWL Series imaging telescope, Artesky UltraGuide 60mm f/4 guide scope and ZWO ASI 224MC guide camera. Also, an Optolong L-Pro 2" light pollution filter.
      After months of imaging and getting more experienced with PixInsight, it was just a matter of waiting before I could have another go at one of my favorite targets. And maybe give it a little more justice.
      This project took me more than a month, due to the rare clear nights opportunities I have had here lately.
      I started acquiring in January and finished a couple of weeks ago.
      M42 taken over 8 nights, under my Bortle 5/6 sky.
      Total integration time: 18h 04m 00s for the nebula. 714s (14s subs) + 2065s (35s subs) for the Trapezium and the core.
      Here are the acquisition details:
      Mount: Sky-Watcher NEQ6 Pro
      Telescope: Tecnosky 80/480 APO FPL53 Triplet OWL Series
      Camera: D5300 astromodified
      Reducer/flattener: Tecnosky 4 elements, 0.8x
      Guide-scope: Artesky UltraGuide 60mm f/4
      Guide-camera: ZWO ASI 224MC
      2021/01/12: Number of subs/Exposure time: 33@300s. Notes: L-Pro filter, no Moon
      2021/01/13: Number of subs/Exposure time: 33@300s. Notes: L-Pro filter, no Moon
      2021/01/15: Number of subs/Exposure time: 38@300s. Notes: L-Pro filter, Moon 8% illuminated
      2021/01/18: Number of subs/Exposure time: 36@300s. Notes: L-Pro filter, Moon 30% illuminated
      2021/02/13: Number of subs/Exposure time: 30@300s. Notes: L-Pro filter, Moon 4% illuminated
      2021/02/14: Number of subs/Exposure time: 23@300s. Notes: L-Pro filter, Moon 9% illuminated
      2021/02/15: Number of subs/Exposure time: 51@14s + 48@35s. Notes: L-Pro filter, Moon 15% illuminated
      2021/02/17: Number of subs/Exposure time: 11@35s + 38@180s + 1@300s. Notes: L-Pro filter, Moon 30% illuminated
      Total exposure time (main integration): 65040s = 18h 04m 00s.
      Total exposure time (35s integration): 2065s.
      Total exposure time (14s integration): 714s.
      Pre and post-processing: PixInsight 1.8.8-7.
      Full HDR Version:

      Masked Stretch Version:

      Blended Version (50% HDR + 50% Masked Stretch):

      To my personal taste, I like the blended version the most. I think it brings out the best of both worlds (HDR and soft, less contrasty but more colorful look).
      I must say, I am very pleased and happy with the result. Not to boast, but I think I have come a long way since I started.
      Obviously the better gear and the much, much longer integration time helped.
      I think I actually spent more time post-processing it than acquiring it. Especially since I had to do the work almost twice: I post-processed the HDR and the Masked Stretch images separately, making sure I used the same processes and with the same strenght in both, so that I could combine them effectively, if I decided I didn’t like the look of the HDR alone. I also think I managed to tame the stars a lot more, compared to my previous post-processing attempts.
      As usual, here’s a link to the full resolution image(s): Orion Nebula (M42), De Mairan’s Nebula (M43) and Running Man (NGC 1977)
      Thanks for looking!
      C&C welcome!

      After a very sturdy tripod and 'head/mount?' for general photography at the current moment but to also use for a Sky guider when I get one in the future
      My questions are;
      Which tripod do I need to handle a small scope and or camera with a big lens attached to sky guider, Tripod budget less than £100 Which sky guider should I go for to image the milkyway and nebula? probably 6-8 lbs payload? Budget less than, £400 Do sky guiders come with their own mount? I heard something about a ball head, mount budget less than £50 Is there anything else I may need with what I have mentioned, power, adaptors, filters etc. Much appreciated, I am new here so I hope this is ok to ask. I currently own a NEQ6 with two small telescopes which I have problems with that I will discus in another topic, so I know how to image that way, but I fancy something small and less stressful in the meantime.

      Hi I've got an 8" dobsonian and I just got a dslr to connect to it. Obviously there's no tracking so what kind of things can I capture. Will I be able to do dso and planets?
      Thanks

      I am looking to return my Powerseeker 114eq and get a XT6. I know that my canon rebel T4i will not reach focus. It wont travel enough inwards. I want to know, which is best? Plan A is trying to use Barlow or eyepiece projection. Which will magnify less, eypiece or barlow? Are there any tips for both of tose methods and how to use eyepiece projection? Then, Plan B is moving the mirror. I cant find any good tutorials either. Thanks in advance.
