    I love the star trails shot (actually I love both) but especially the intro when panning out from the dish with the music choice, just like it should belong in a movie. 

    Thank you for all your dedication and hard work that you make look so effortless Paul. 

    It's a beautiful location and your blessed with amazingly clear skies in the east of England. 

    Lee 

    Thanks Lee - super kind.  We've actually only had about 4 clear nights since the start of the year, but I've tried to max out as many of them as I could!!  I appreciate the support.  🫡

    Well I have seen lots of star trail images but this one is on steroids.Amazing, it would make a great book cover.👏👏

    Very kind - really appreciate that.

    Hi Paul,

    Another great video I happily watched and the star trail image was just amazing - love it and the 'hidden nebula' 😄

    Super well done :) !!

    Thanks so much Ger - really appreciated.

    That first image is a rather spectacular one. In some ways I feel the light pollution is an integral part of the image, enabling you to silhouette the background which to my mind helps with the composition.

    I note that the star colours are quite saturated, presumably enhanced in post, but I like that, it's the artistic aspect which appeals rather than any scientific accuracy.

    Ian

    Thanks Ian. I agree re the light pollution, which is just as well as it’s rather unavoidable round here!

    Yes I’ve played with the hue and saturation in post, as well as applying a slight spin blur. Definitely art rather than scientific accuracy in what I do! There are plenty of other people producing beautifully accurate star colour shots, so I’m trying to be a bit different in this, whilst generally getting the message out to the wider world that not all stars are white!

    That's the best star strails pic I've ever seen! Stunning!

    Very kind of you. It was really enjoyable to make.

    Great images Paul!

    You are right about the setting- the One Mile Telescope makes a very evocative foreground.

    I look forward to your return visits.

    Thank you. It’s nice to have a foreground like that which isn’t hours of driving away! Shame about the local light pollution, but it could be a lot worse.

  5. In a field about 4 miles outside Cambridge is a treasure trove of astrophysical history. Giant iron skeletons tower above the hedges and ditches, interspersed with rows of wires strung between wooden posts, resembling a dormant vineyard.  This is the Mullard Radio Astronomy Observatory, at which in 1967 a young Jocelyn Bell discovered pulsars using an instrument she helped to build.  

    During one of the scarce clear nights in January, I visited with the intent of capturing three shots.  I'd wanted to do an extended star trails image over the beautiful structure of the One Mile Telescope, a foreground that in my eyes never gets old.  Additionally I'd planned two mosaics, one of the Cygnus Milky Way and one of the Orion region, both with the One Mile in the foreground.  

    In the end I captured over 5 hours of star trails, and after painstakingly removing all the usual plane and satellite imperfections (and dealing with an accidental shift of camera position when I changed the battery), I got a shot that I'm super happy with - definitely the best star trail image I've created and I had a lot of fun with editing it.

    Unfortunately the two mosaics I captured proved almost completely unusable.  Whilst they stitched (a miracle in itself given the haphazard way I shot them), the images suffered from horrible gradients and brightness differences that I've managed too get almost nowhere with, despite some very helpful suggestions from people over on the Image Processing part of this forum.  I just couldn't get an image I was happy with - maybe some data to return to in the future, especially if I ever graduate beyond PhotoShop.  I felt rather silly wasting a stunning 5 hour period by over complicating things; I should have gone for a shorter focal length and just captured more exposures, rather than going overly long (85mm) - it's not as if I was planning on printing the final image super large!

    So a few weeks later I returned to capture the Orion image at a much more sensible 35mm; sadly it was too late in the season to capture Cygnus as it was now well within the murk after sunset - one to save for next year (provided no work has started on the giant solar farm currently awaiting planning permission for the area!).

    As usual, I made a video journal of the night, which you can see below.

    I'd welcome any feedback and thoughts - clear skies!

    Hi

    I tried gradexpert, (my goto tool for this - it is free and vg normally), but was roundly defeated!  Fiddled with DBE in PI but also butt kicked.  So I tried old school:  take an image layer and gaussian blur so all stars are blurred out and gone (gaussian radius about 20-30 pixels on your posted jpeg image).  Subtract the gb image from the original. A bit of levels and repeat.  This is what came out... hope this is useful ?

    Simon

    original - quick and dirty crop for square, suggest you add a black background to your mosaic to square it up

    I really appreciate that. I’ll have a look at that method later today (along with hopefully revisiting the location to try again with a wider lens). Definitely something to work with - massively thankful.

    The idea of learning another new application doesn’t fill me with excitement, so anything I can do in PS is a bonus!

    Thank you Paul for another wonderful trip out on your vlog. All the images are amazing but I especially like the boat shot with Orion and the wind pump centred with the night sky, simply brilliant.

    I'm looking forward to milky-way core season soon, I'm anticipaing around very early April to start to try a pano arch image again. Though last year was up until end of May here. Will try flats this time (when I've perfected how to take them with this lens) to hopefully avoid join marks when stitching because of the vignette of the samyang 14mm f2.8. Thank you again for a wonderful vlog and teaching us how to get even better and more natural ways Widefield astrophotography

    Really glad you enjoyed it, Lee. Very excited to see your arch pano - wishing you clear skies for that!! Hope you’re still enjoying that Samyang 14mm!

  8. Taking nightscape images can be time-consuming.  Most of us live under fairly mediocre skies so a drive of maybe a couple of hours to a darker location isn't uncommon, and once you've made that journey you may as well stay a while.  Unless you happen to live atop a cliff or in an attractively derelict stone barn, you probably don't have the ideal foreground in your garden, so the comforts and advantages of deep sky imaging - sipping tea inside while the gear does all the work - often aren't open to you.

    But not everyone is able to spend hours away from home at night.  Work, family, or even health concerns could mean we're limited in the time we can spend outside trying to capture usable images of the night sky.

    So what would happen, I wondered, if I only had an hour?  An hour to leave the house, get to a decent location, capture a shot and get home.  Could I capture a nightscape shot I was happy with and enjoy the experience as well?

    Back in January I had the perfect opportunity to give it a go.  A crystal clear evening - like hens' teeth so far this year - coincided with a commitment I had later that night.  So I had a crack at The 60 Minute Nightscape.  And because I'm a little unhinged, I filmed a vlog of the attempt as well (hint: don't film a vlog if you want the evening to also be relaxing!).

    So here below is my final image and the video of its capture.  It won't win any prizes, but in the circumstances I was reasonably happy, and when I posted it on my local village Facebook page it got quite the reaction.  It turns out it is possible to take a nice image whilst only being away for an hour.  For the avoidance of doubt, however, I don't plan to share that revelation with my wife……

    Hope you enjoy….

  9. Hi all

    I'm hoping someone can point me in the right direction, or tell me to stop pursuing a lost cause!

    Recently I attempted a widefield nightscape mosaic at 85mm of the Orion region.  I wanted to create something super detailed, but I've ended up with a bit of a monster and now wish I'd just gone with fewer panes and a wider lens.  But the night has personal significance and if I'd love it if I could salvage something.

    I ended up with 18 panes in the mosaic, each of which was 3x120s exposures at ISO800 and f/4, using a modded Canon 6D.  I also shot flat frames "just in case" - I hadn't really expected to need them at f/4 with the Samyang 85mm (widest aperture is f/1.4).  Having stacked each pane in DSS, after a bit of persuasion in PTGui the whole thing stitched, which I was delighted about.  

    But I seem to have lots of "micro-gradients" that resemble a vignette in each frame, despite taking flats.  I've never seen this before, but also I've never attempted a mosaic of this complexity before.

    The underlying data seems reasonable (nice stars, good detail in the Rosette etc), so I'm after suggestions around how I can clean up these horrible gradients / vignettes (obviously I'm not concerned about the bright horizon).  I use PhotoShop for editing, and have tried using AstroFlat Pro, but the result is fairly ugly.  

    Any suggestions would be very gratefully received (as I say, even if the suggestion is "don't bother, Paul") - thank you in advance.

    I've copied below the lightly stretched output from PTGui, together with the image map from PTGui showing how the image stitched.

    Excellent, thanks, the boat is my favourite. Also thanks for adding the exposure details, they may not work in all cases but it's useful to have a starting point.

    I've subscribed to your YouTube channel so looking forward to catching up on the previous content as well.

    Thanks John - appreciated. I should probably start adding the exposure details on the final images on my YT channel, but I’m not especially talented at the graphic overlays so it adds quite a bit of time at the moment. Hopefully that’ll change at some point!

    Excellent work!  My personal taste veers towards the boat composition. 

    I may have taken off a layer prior to a selfie, in the past...

    Thanks Paul. I think I agree with you. I like the pop in the h-alpha images, but the boat has something about it. Ha ha - I think I would have needed to take several layers off!!

    Very nice once again. I too particularly like the boat image and the wind pump looking north east.

    The amount of detail from the moon light was wonderful and it made the frost and dark wood really stand out.

    Nice idea to include the owl singing along in the video 🙂

    Dave.

    Thanks Dave - appreciated. It was a very obliging owl!!

    Really amazing pictures. 

    I live 20 minutes away from the Fen and regularly take the dog there for a walk (swim). It is really great to see a place I know well in a very different light, thank you. 

    Fantastic! It’s a lovely place to go to. Thanks for your comments - very kind.

    Fantastic images and video diary. How does that star glow filter work, I’ve never heard of that before?

    Thanks Geof. The Starglow is a bit like a fog filter, and it applies a slight blur that makes the brighter stars pop and their colours come through a bit more. It’s similar to the effect from a sky with a thin layer of high citrus. It looks like a small pane of glass and I simply wave it in from of the lens when I take the images.

  12. Last week during the cold snap I headed to Wicken Fen nature reserve in Cambridgeshire, a wildlife haven comprising a few hundred acres of unspoilt fenland.  It's a location I've shot from a few times before but I've never been wholly happy with the results.

    I had the place to myself and so the evening was spent in the company of owls, the distant shriek of muntjacs and the occasional unidentified shuffle from the reedbeds.  It was a 50% moon, and its silvery glow sparkled on the droplets of frost that adorned the long wooden boardwalks and the fronds of the reeds that swayed gently in the breeze.  It was bitterly cold, but I was well wrapped up and I could simply enjoy the night.

    My aim for the night was to capture some shots of Orion over the pretty old windpump - a feature of the Fen - and over one of the boardwalks that we'd scouted out earlier in the week.  With a relatively unambitious plan, I was able to spend the time to get some higher quality sky shots using the tracker and to use the h-alpha filter to bring out some of the lovely nebulosity in that part of the sky.

    For those interested, I also made a video journal of the night, which you can find linked at the bottom.

    Overall it was a really enjoyable night and I'm pleased with the images I made.  I wish I'd had the foresight to place myself in the scene in "Boardwalk to the Stars", to give it a human element; without that it seems possibly a little sterile.  That said, I was dressed up like the Michelin Man, so it may not have been as effective as I'd have liked!

    Hope you enjoy, and always welcome feedback and suggestions. 😊
