  1. A few days ago I did a 12 hour day to night to day time lapse at Ribblehead Viaduct in the Yorkshire Dales, in all I took 1,830 images. Below is one of the images which I've processed separately in Lightroom and Photoshop to show some of the clear sky and Milky Way showing through the clouds at the Viaduct. The exposure for this particular image was 20 seconds at f1.4 and ISO 6400 with my Sony A7Sii and Samyang 24mm f1.4 This image was taken at 11:48pm and is image number 772 out of the 1,830 that I took The full video can be seen at the following link and this image comes just before half way of the actual time lapse clip https://www.youtube.com/watch?v=dmFglty2XT8
  2. The moon does have an effect but there is also a setting on the Timelapse+ view intervalometer that I've been playing with, it is an exposure adjustment for night time compared to day and the default setting is -1 stop so the night exposures are automatically 1 stop less than day to ensure that the sky is noticeably darker, I had it set to -1/3 stop so I might try the default setting of -1 stop next time, I could also darken the sky by adjusting the processing on the night time key frames. It's all in the experimental stage at the moment as this is the first time I've tried doing "Holy Grail" time lapses Best wishes Gordon
  3. Actually, the milky way is visible you can make it out behind some clouds as it moves towards the right of the frame and then it disappears to the right, it's just after the 40 second mark
  4. I spent last night at Ribblehead Viaduct in the Yorkshire Dales shooting another "Holy Grail" time lapse, this time I wanted to go all the way and shoot a time lapse that went from day to night and then back to day again. The weather forecast wasn't brilliant but sometimes you've just got to go out and do it and hope for the best. Although the majority of the night was cloud bound there were a few short clear spells and I managed to get the milky way crossing the sky albeit behind some clouds. I started at about 7pm (an hour before sunset) and finished at 7am (an hour after sunrise). I used my Sony A7Sii and Samyang 24mm f1.4 lens, my Dynamic Perception slider with Sapphire Pro pan and tilt head and NMX pro controller for the camera movement and my Timelapse+ view intervalometer for handling the ramping of the exposures needed during the night. As mentioned on a previous post you programme the camera movement into the NMX controller via a blue tooth phone app and then after taking a correctly exposed image at ISO 100 and f1.4 you set a few parameters into the intervalometer such as longest exposure and highest ISO and then the intervalometer makes the necessary exposure adjustments during the night and also moves the slider after each exposure so apart from periodically checking on batteries, cables, etc it is nicely automated, any flickering from the exposure changes is handled using a plug in for Lightroom from Timelapse+. In all I took 1,830 images with exposures ranging from 1/2500 of a second at f1.4 and ISO 100 to 20 seconds at f1.4 and ISO 6400. That is over 21 stops of exposure difference during the night and each exposure change is made in 1/3 stop increments so the intervalometer has a fairly busy time during the night. During the night the moon came up which added a bit of extra illumination to the landscape. Hope you like it, the video can be seen at the link below and is available in 4K https://youtube.com/watch?v=dmFglty2XT8&t=11s Best wishes Gordon
  5. I was out all last night by Nidd Gorge in Harrogate shooting a "Holy Grail" time lapse (time lapse that runs from day to night, night to day or day to night to day, etc). It is technically difficult to do because there are many exposure changes required during the period in order to take into account the huge difference in lighting over the period. There are several ways of doing this, some easy, some hard and different methods can yield different results, some good and some not so good. The method I used was a special intervalometer called a 'Timelapse+ view' where you set a few parameters and start off with a correctly exposed shot and it then takes care of the exposure changes during the period of the time lapse, there will be a degree of 'flicker' visible whenever the exposure is changed but this is easily taken care of using a plug-in in Lightroom or using the "Holy Grail" facility in LRTimelapse. This was taken with my Sony A7Sii and Samyang 24mm f1.4 lens and I took 1387 images altogether over about 9 hours. The exposures ranged between 1/320th of a second at f1.4 and ISO 100 to 20 seconds at f1.4 and ISO 500, I also used a Dynamic Perception Stage One slider with Sapphire Pro pan and tilt head for the movement. The intervalometer takes control of the slider and the camera, you program the move into the slider using a phone app, then programme the parameters for the exposure range into the intervalometer and then start the slider program and then the intervalometer, the intervalometer then triggers the camera and after the exposure has finished it triggers the slider to move before firing the camera again so it is nicely automated. It wasn't a perfect evening for my first outing with this gear what with the clouds and a full moon but the end result showed what the system is capable of, towards the end of the video clip you can make out the Pleiades and Hyades star clusters rising, unfortunately the moonlight washed out most of the sky when the clouds cleared. The changing brightness of the landscape isn't flicker, it is caused by shadows from the clouds and moon.

  6. Hi I have done a workshop and talk on time lapse in NEAIC in New York in April, I am quite willing to come and do talks and workshops on this including how to set up, using camera sliders, settings, processing and rendering to video. All I would ask is that accommodation (if needed) and travel expenses are reimbursed Best wishes Gordon
  7. Hi I got the trailer from a company in Germany called "Benpacker" and the model is Trek. It is very rugged, it even has disc brakes on the wheels to slow it down on steep downhill gradients and it will hold up to 40Kg Here is the link Benpacker hiking trailers Best wishes Gordon
  8. Thanks Mark, my trips will continue whenever I can and when I'm invited. This year my talk and workshop were both on time lapse with a DSLR so despite me not being able to do deep sky there is still the time lapse and there is a lot of interest as the workshop has plenty of attendees Best wishes Gordon PS By the way, this was my first time using a drone
  9. I spent the night at Ribblehead Viaduct last night shooting some time lapse, star trails and an animated star trail. After selling my telescope gear (no space to use it since moving to Harrogate), I used some of the money to buy myself a hiking trailer and a drone. The trailer means that I can carry more kit with me without making my back and joints worse than they already are, after a bit of research online I got a Benpacker Trek from Benpacker in Germany and this was my first outing with it. I wanted to get to the viaduct before it was dark to shoot some drone footage of the area and while I was waiting for it to get dark a young couple (Ben and Sinead) and their dog came along and we got talking about cameras, drones and the night sky and before we knew it over an hour had passed. The time lapse and star trails were shot on my Sony A7Sii with a Samyang 12mm f2.8 fisheye lens with exposures of 30 seconds at ISO6400. For the drone footage I used some of the quick shot modes and active track (me leaving the site in the morning). This is a particularly nice dark site that is easy to get to by train although it never really got fully dark last night as it's still mid summer, I plan on coming back here in the autumn and winter months. The area is really scenic and apart from the occasional bleating of the sheep in the distance it was absolutely silent. The video can be seen at the following link on my YouTube channel and it is available in 4K https://www.youtube.com/watch?v=kLc93QN1_W4&t=20s
  10. I have finished rendering the video for the time lapse clips that I shot last night on top of the old railway viaduct that spans Nidd Gorge in Harrogate, North Yorkshire. I set up at about 7pm last night and finished at 6am this morning. All the images were shot on my Sony A7Sii and Samyang 12mm f2.8 Fisheye lens, all exposures were 30 seconds at f2.8 with the first clip shot at ISO 12800 and the second clip at ISO 6400. Towards the end of the second clip a couple of insects decided to crawl on the lens! In the second clip the foreground and background movement was created by my Rhino Camera Gear Evo carbon slider with Motion and Arc, I also made a star trail image from the first clip and I have included this in the video. I took just over 980 images altogether. The video can be seen at the link below and is available in HD and 4K Best wishes Gordon
  11. Last night the weather was good so I decided to spend another night in the very beautiful area of Nidd Gorge. This time I wanted to take some pictures and a time lapse of the viaduct with the night sky. The moon was almost full and it was to the left of the scenes as you look at them. I started shooting at 7pm and finished about 5am today. I took over 900 pictures altogether. These were taken with my Sony A7Sii and Tamron 15-30mm f2.8 lens. For the second clip I used a Syrp Genie panning motor. Exposures were all 30 seconds at f2.8 and ISO 4000 During the night I heard an otter going for a swim, some owls calling to each other and one particularly loud pheasant that had a lot to say for itself. The video can be seen at the link below and is in HD and 4K https://www.youtube.com/watch?v=dMQxeXQ4tgM&feature=youtu.be
  12. Hi As some of you may know, I have moved to Harrogate in North Yorkshire from Hereford. The last few weeks have been fairly hectic but on the 26th I managed to get out to shoot some time lapse and a star trail image. This site is about 2 miles from where we now live and it is a great place to walk our boys. I spent the night here from 7pm to 6am the following morning and shot 3 short clips. The area is Nidd Gorge in Harrogate and I set up at Scotton Weir for the night. Clip 1 - Looking directly at the Weir. Sony A7Sii and Tamron 15-30mm f2.8, 440x30 second exposures at f2.8 at 15mm setting and ISO 16000 Clip 2 - Looking away from the weir. Sony A7Sii and Tamron 15-30mm f2.8, 280x30 second exposures at f2.8 at 15mm setting and ISO 25600 Clip 3 - My view of the night sky from my bed roll. Sony A7Sii and Samyang 12mm fisheye f2.8, 280x30 second exposures at f2.8 and ISO 25600 During the night there were two lots of mountain bikers with very bright lights came past and also the house on the other side of the weir had an outdoor light that came on periodically but I think these added nicely to the lighting effect of the video. There were some thin whispy clouds during the evening as can be seen on the videos, during processing I noticed that the last 40 frames of the first clip the sky was clear so I used these to create a star trail image. On the last two frames of this star trail section the light came on at the house but I left them in as the lighting effect and colours that came out on the right of the image was really pleasing. The RAW frames were processed in Adobe Lightroom and the video rendered in Adobe Premier Pro, the star trail image was done using layers in Adobe Photoshop. The video can be seen at the following link and is available in 4K https://www.youtube.com/watch?v=AFiIdrclE0E Best wishes Gordon
  13. Thanks for the comments Actually, the lengthy bit is gathering the data. For these two clips I was on top of Hergest Ridge all night and each time lapse took about three and a half hours to shoot with over 350x30 second exposures for each. The trick is to shoot at as high an ISO as possible after taking into account that at 30 seconds and f2.8 I'm at the limit of photon gathering ability before star trailing. I use a technique called ETTR or "Expose To The Right" where I check the histogram and make sure that the sky part of the histogram is as far over To the right as possible without clipping it. You must shoot in RAW and anything automatic must be switched off so no AWB, noise reduction etc. The resulting images on the camera look terrible with grossly over exposed sky etc but this is ok because you pull it all back In the processing which is the easy bit, that takes me about 5-10 minutes in Adobe Lightroom, you process one of the 700+ images and copy and paste the workflow to all the others. Then export the lot to jpeg, import into Adobe Premier Pro, add music, text screens etc. It is very easy to be honest once you get the hang of it. I have put a 10 minute video on my YouTube channel which shows time lapse clips from various locations during the last 18 months with some still frames taken from the time lapses. There is an artistic element involved as well In picking a good location and using things in the foreground and background to create extra interest such as the pool of water Best wishes Gordon
  14. I spent the evening up on Hergest Ridge in Kington Herefordshire again last night as the weather was good. I knew that it had been raining up there earlier in the week and I was hopeful that there were going to be some pools of water to catch some reflections from the stars during the time lapse. I found one pool which is where I set my Sony A7Sii and Tamron 15-30mm f2.8 zoom lens on my Rhino Camera Gear Evo Carbon slider with motion and arc. I shot two short time lapse videos during the night shooting a total of over 700x30 second exposures with the zoom lens at the 15mm setting and f2.8 and at ISO 25600. Although it was quite breezy the water in the pool remained calm allowing for some nice reflections. In the second clip the very bright areas are from the light pollution in Leominster and Kington The video can be seen at the link below and is best viewed in at least HD https://www.youtube.com/watch?v=RbT2hpJmTJ4&feature=youtu.be
  15. Last night the weather forecast was good although the moon was going to be in the sky until close on 1am so I went up to Hergest Ridge in Kington again with the intent of utilising the moon to create some nice lighting effects. During the night I did two time lapses. Time lapse 1 was of the monkey puzzle trees with the moon moving across the sky directly behind them, this was help create some moving shadows and highlights in the foreground. I used my Sony A7Sii and Tamron 15-30mm f2.8 lens with the shutter speed set to 30 seconds at f2.8 and ISO 3200. I didn't use my Rhino Camera Gear for this for two reasons, I wanted the trees to remain stationary and as I hadn't charged the batteries I wanted enough power for the second time lapse. I took about 280 frames for this time lapse. Time lapse 2 was of the milky way moving away from the monkey puzzle trees and as I wanted to follow the milky way I used the slider. I started the time lapse with the moon still in the sky to show the effect that moonlight has in washing out detail in the night sky and also the effect it has on the colours. I shot this with the same exposure settings except that I used ISO 25600 to help capture the milky way better. Following this I turned the camera round and took a couple of pictures of Orion which had just risen but I will post those later. After I finished I had a short nap on my bedroll before heading back down to meet my brother after which we went for breakfast in Kington at the Border Bean café. The Video of these two time lapses can be found at the following link, it is best viewed in HD or 4K https://www.youtube.com/watch?v=VI_XqK_wwU0&feature=youtu.be
  16. Hi Mark Thanks for the comments, we haven't moved yet but are likely to be within the next few weeks so it looks like it will be my last attendance on the 7th I'm afraid Best wishes Gordon
  17. On Sunday the weather was looking good and I was planning on doing another time lapse. I was originally going to go up Haugh Woods in Hereford but when I checked the forecast sites the weather looked better at the Grwyne Fawr reservoir and dam (where I had previously done a time lapse last November) so that's where I went, my good buddy Anne Shuker gave me a lift to the end of the road near the dam and I headed off up the track to the reservoir itself. I set everything up and waited for the moon to set and started the time lapse shortly after 10pm and it ran till just after 3:30am. In all 582 x 30 second exposures were taken with my Sony A7Sii and Tamron 15-30mm f2.8 lens which was set to 15mm and f2.8 and the ISO on the camera was set to 25600. Motion was created using my Rhino Camera Gear Evo carbon slider with motion and arc. Although the forecast showed clear skies for the whole night there were some whispy clouds blowing over which created a nice effect in conjunction with the sky glow caused by the light pollution from Abergavenny and the moon which had just set behind the hills. I managed to get some nice reflections in the water of the reservoir but it was quite breezy for most of the night so not as much as I had hoped. The RAW files were processed in Adobe Lightroom before rendering to video in Adobe Premier Pro It is best viewed in at least HD and it's also available in 4K both at the following link https://youtu.be/Y_X7f-g47uM
  18. Thanks Nige When I posted it I thought the link looked faint against the white background. I will have a look at trying to post it differently later when I'm back on my desktop Gordon
  19. I've just checked the link above, it goes straight to the page with the video on it, just click the video. It works on my phone perfectly ok
  20. I have been having a play and trying to learn to use Adobe Premier Pro for creating videos for my time lapse work. This is my first effort and it is to give some pointers as to how to do time lapse videos of the night sky but also utilising the same data to make star trails and still images. In all I used Adobe Bridge, Photoshop, Lightroom and Premier Pro in the making of the images and time lapse in this video. The music was obtained from the Free Music Archive. All of the data was taken over a period of more than a year and amounts to several thousand images being taken in different locations. All the details as to the equipment that was used is in the video. It is on my YouTube channel at the link below and is available both in HD and 4K for those with a very fast connection and a suitable monitor/TV https://www.youtube.com/watch?v=dc0_aA89Uks&feature=youtu.be
  21. I was at Eardisley again doing some more work at the house and as the weather was good I took my camera gear with me. There was only just about 3 hours of proper darkness so this is two time lapse videos on two nights. It was taken with my Sony A7Sii and a Samyang 12mm f2.8 fisheye lens. The movement in the scenery was created using a Rhino Camera Gear Evo Carbon slider with Motion and Arc. I took 602x40 second exposures at f2.8 and an ISO of 25600. Just before half way through the video there is a blue and white flash of light coming from the house. See if you can guess what they were Rather than post the video here is a link to it on my YouTube channel where it is best viewed in HD https://www.youtube.com/watch?v=4fpXbB6CWss&feature=youtu.be Best wishes Gordon
  22. Hi I haven't posted in a while as I have been busy helping maintain my parent in law's house after they died and there is a lot of work that needs doing there while it is being sold. This has meant that my main imaging sessions have had to take a back burner for a while. In the meantime I have been having a go with some simpler imaging with my DSLRs doing stills, star trails and time lapses. Here is a combination of what I have done during the last 12 months. They were taken with a Canon 80D and more recently a Sony A7S II with a Samyang 18mm f2.8, Sigma 10-20mm f3.5 and Tamron 15-30mm f2.8 Exposures range between 10 and 30 seconds and ISO between 800 and 25600. I also use a Rhino Camera Gear Evo carbon slider with Motion and Arc for the movement of the foreground and background in some of the time lapse clips. A combination of Adobe Lightroom, Adobe Bridge, Photoshop, Time Lapse Tool and Movie Maker were used in the processing. The movie is at the link below and is best viewed in HD Hope you enjoy it Best wishes Gordon https://www.youtube.com/watch?v=R161lbi--G4&t=47s
  23. Hi Here is another narrow band image that I took with the new Microline x814 camera, it uses a Sony interline chip with 3.69 micron pixels and has over 9 mega pixels in the sensor. This was attached to my Televue NP127/FLI astrograph in place of the Proline 16803 as I wanted to try some narrower FOV higher resolution shots. Exposure times are as follows Ha 23x10 minutes, OIII 18x10 minutes and SII 22x10 minutes. There is very little SII in this subject. All the raw frames were calibrated with darks, flats and bias frames. Processing was mainly stretching the weaker channels, colour combine to HST palette, levels with some minor curves adjustments, colour balancing, contrast adjustments, a little high pass filtering and shadows and highlights. The large size image can be seen at the following link http://m8.i.pbase.com/o9/29/869929/1/160651878.GFEsNwru.NGC6888HSTmax2000.jpg Best wishes Gordon
  24. Hi This is another image taken with my new FLI ML x814 camera on my Televue NP127/FLI astrograph. As an experiment I took this with the camera binned 2x2 so as to match the camera better to match the pixel size to the optics. Unfortunately my light panel gave up the ghost so this hasn't had flats applied to the data. Exposures are 18x10 minutes Ha, 17x10 minutes OIII and 15x10 minutes SII. Processing is mainly stretching the weaker channels, colour combining, levels/curves, colour balancing, contrast and a little high pass filtering (some purists may object to this but I won't lose any sleep over it as I'm already having difficulty in sleeping at the moment....lol). I may try this again but without binning The larger version is at the following link http://m1.i.pbase.com/o9/29/869929/1/160610691.7xWNsSok.IC1396HSTmax.jpg Best wishes Gordon
  25. Hi Guys Thanks for the comments, this really is a nice camera despite its very small pixels (3.64 micron) which is really pushing the boundaries and telescope optics not to mention sensitivity with narrow band but I still managed to get reasonable results with 18x10 minutes per channel. I wanted a chip to get a smaller FOV but with high resolution and I think I've got that Best wishes Gordon
