I've been absent for the forums for a while as I packed up my telescope with an impending house move.  Which has now taken place and the telescope will be retrieved from safe storage.  However a few nights ago I sat out in my new garden looking at the night sky.  I grabbed my trusty Canon 40d and set up my tripod.   Attached are some of the images taken.

Time of night, length of exposure? Beautiful, clear skies, in the first, the Milky Way is just beginning to show. I've had those for a couple of nights, now, but full Moon has spoiled much of any chance to see deep-sky.

Your second image (showing Cassiopeia) is much like my view from the barnyard behind my home, with trees blocking a portion of my NE view. My view is a bit further south than yours, though. I'm at 35 degrees, instead of 52, so time of night would be very different to get that particular alignment.  I have to wait until early AM this time of year to get M31 high enough to get it out of the light-polluted lower sky around me. Most other things as well. Do you get that dark a sky all the time?

Hope  you settle well in your new home.   Can be traumatic moving house, so hopefully any induced stress has dissipated.   One big bonus you have illustrated in your post, excellent night skies.  Lovely Jubbly.  We can look forward to more Images in future.        

Best Wishes, hope you and yours have a great and happy life in your new home.

Picture No. 1: To the left, Cassiopeia just above the tree tops, above Cepheus with the nicely displayed pinkish-red Garnet Star (Mu Cep); to the right: Cygnus, with star clouds of the Milky Way.

Picture No. 2: again Cassiopeia and Cepheus; the Double Cluster just above the trees in the middle; Kemble's Cascade to the left of it visible.

Picture No. 3: the south-western part of Pegasus; the globular M 15 can be spotted; to the right, the "Job's Coffin" asterism of Delphinus.

Picture No. 5: again the Cassiopeia - Cepheus region.

Seems to be a fairly dark spot you've chosen - a good hunting area for your 8"; enjoy the views!

Congrats on the move. I did the same about 3.5 yrs ago and swear i will never do it again. The stress of it all (legal paperwork etc) just aint really worth it. I was so stressed that i locked up the old house and dropped the keys into the estate agents and drove to the new house and then and only then did i realize i had left something very important in the old house...................

MY DOG.

Thankfully the new owners are also dog lovers and they looked after her until i went back the same day to collect her. They thanked me for the bottle of bubbly i had left there for them, but said "you can keep the dog".

Haha........i even left a 32" Sony Trinitron TV (big back) there, because i tried to sell it online, but no takers and i didnt need/want it and was too heavy to chuck in the skip.

In saying all of this i do love the location i am in now (and so does the dog). Im just about 30 miles west of Dublin city (but in a different county). Very much a rural location with mile upon mile of open county within 5 minutes walking distance to my north,west and east. Skies are a lot darker here (even in my own garden) than where i used to live (about 20 miles south of Dublin city.........a mile or so from the beach). 

Your view looks good. Nice and wide and open. Hard to tell just how dark your skies are without any details of the images you posted.

Enjoy your new life up there in Staff.

Here's a snap of my new "Castle":

iso1600 18-200mm canon lens at 18mm f3.5 and exposures of around 20-30 seconds.    But the 40D has now being joined by a 77D.  

We're lucky in that we are at the end of a private road and there is no street lights close to us.  The property is surrounded on three sides by open fields.   The view to the north can get light polluted as that looks over the town.  I hope to create a pier to mount the telescope on. I'll keep you updated on its progress.

Well ran the 77D out the other morning.  Images are taken at around 15 secs at f3.5-f8. And between 3200 and 6400iso. Not the clearest of nights when the images were reviewed, but the sky appeared clear to the naked eye.   I tried to focus more on Orion as this cluster is prominent to my southern aspect.

Excuse my ignorance, but I assume he stands on his head in Australia.   Just something I'd not thought about until just.  

The orientation of objects in the sky is reversed in the Southern hemisphere (from the perspective of someone living north of the equator), so Orion is upside-down there and Sirius is placed above it high in the sky. Here it is below Orion and never rises too high. Have a play around of Stellarium to see for yourself.

Ill be checking it out later.  But it makes perfect sense.

Orion is also referred to as saucepan Southern Hemisphere

      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.

      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!

      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
