Yeah that is a good shot buddy, well done. Ray -
Wow mate, 2 laminectomies and a fusion, ouch. Ray

I know it's very hard to harden up to back pain - had it a couple of times when I've done something stupid (easy to do stupid things to your back when you're 6 foot 2). My son is 6 foot 4 and I hope I have lectured him long and hard enough about looking after his back (although he did have a car hit him at the back at 50 mph which didn't do his neck much good ).

WOW. Ripper shot mate. Shane -
Hi Greg, I have had 2 lamenectomies and a vertabrae fusion. I always have some pain but this time it was a lot worse than usual. I just have to deal with it as I have since it all started about 10 years ago. The way I look at it, even though I bitch at times, is there is always someone worse off than me. In other words "harden up princess" lol. Shane

Single shot of Ribblehead Viaduct at night

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 - Earlier

Sorry to hear that Shane - what is the cause of the back trouble? My missus has back trouble but a trip to the chiro once a month manages to keep her on her feet. Greg

AP mount.......one of a few on my short list of dream mounts that I will probably never own. Others are 10 Micron and SB Paramount MX+. Shane

Beautiful Prof. Unfortunately my job trial ended in abject failure due to my back incapacitating me, so I have not been able to get out. Rather typical as I have had some nice clear skies and inabilty to take advantage. Shane

Great capture ! Dave

(September) Just a quick note: It has been confirmed that my PSA is now 3.9 which below the median of 6.0 for males of my age. The Cancer is considered "on hold" no increase nor spreading. The result of the re-scan of my heart relating to the Cardiomyopathy Dilation issue in 2012, is that the heart has recovered and functioning normally, there are a couple of small issues, but these have been classed as minimal and of no present concern. The bottom line is to keep doing all the right things with diet and exercise and return for a follow up scan in 3 to 5 years. I like that sort of diagnosis ! Dave- 14 replies

Lovely shot my friend. Ray

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

Interesting. One thing my AP mount does it appear to remember where it is all the time. Admittedly I paid for the privilege of that though. The biggest draw card (apart from everything else) with the AP mounts is running the cables through the mount. I really find that useful. Ray

First "proper" image of the new season. Open Cluster NGC7209 in Lacerta. 3 x Sky 90 array with M26C OSC CCDs. 18 x 10-minute subs. Milky Way background. Greg

Yep, my biggest issue, apart from possible damage to pc, is that when the mount loses power it also loses where it is. So after any power loss I have to muck about, getting it back to a home position, and that is most likely not exactly the same as it was which throws out slews and positioning and needs to have PA etc redone. Shane
-
Very nice Gordon. Shane
-
Good idea mate. I have to agree, power loss can cause some serious issues. For example, my rotator wants to do a 360 turn every time it is turned on which is really dangerous for plugs and cables that don't have enough slack in them (the rotator is strong enough to snap plugs), so I always keep it unplugged in the event of a power loss. Ray

Beautiful mate. Ray

Yeah true Ray. If the latest report from BofM is right, looks like during September & November we are going to see clear skies, but at the cost of an 80% above average temperatures. A very long hot spring/summer. BTW that moon shot was also made up of 11 images in Registax. Thought I would just keep my hand in. Probably would have been better with the 10", but the EQ6Pro really makes it great to get the pointy end of the scope in the right direction. Could be an update next week on the medical situation. Been for further tests. Dave

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. The video clip can be seen at the link below in 4K https://www.youtube.com/watch?v=WS8yLlraktY&feature=youtu.be

Hi Ray, primary reason is power loss. I have had a couple of times where I have had power loss to obs for unknown reason and want to have time to power down pc, mount and camera. Shane
-
What's the primary reason for using it mate? Closing the observatory in a power cut (if the obs is powered) or ensuring you do not lose data? Ray
-
Nice work mate. And yeah, finally get some clear weather and burn offs of barbeques start, we can't win. Ray
