  1. I would be most grateful if you could explain what the 500 rule is, and what the dust lanes are. Cheers
  2. I was actually on Beacon Fell today getting the last few rays of the autumn sun. I have given some thought to photographing there myself. Edit After looking at your link, I shall check out Dunsop Bridge as that should give better results. Cheers Cheers
  3. I've had this project on my "To Do" list for some time. Seeing as the nights are getting longer and there is a cold snap over the next few days, I'd quite like to have my second go at capturing the Milky Way. The first attempt was at Seahouses, along the shoreline with a full moon adding insult to injury. I'm guessing that a big full moon reflecting off the sea was a bad idea. To help me be more sucessful this time, I very much would appreciate any help and advice to achieve this task. I have a Panasonic micro four thirds camera with a 12-35mm f2.8 lens. I appreciate that this is not as wide as I would like but them's the constraints on the project and my wallet. I also have a sturdy tripod and a remote cable trigger to further reduce camera shake. I'm guessing that the first thing I would need is a dark location. Sadly I live in a very bright seaside town famed for its bright lights and replica Eiffel Tower. You only get one guess. :-) I'd appreciate suggestions of dark locations in either Lancashire or, and I say this in a hushed tone, Yorkshire, but not much more than an hour and a half's drive from site to comfy bed. The next part is capturing the Milky Way. I shall be using Stellarium on my phone to give me a rough idea of where to point my camera. When capturing the Milky Way should I: Take one long exposure while trying to eliminate star trails. Take thousands of images and stack them later on my computer Take a video of the night's sky and then stack the video on my computer If I am to take still images, what settings should I set my camera to? ISO Shutter speed Aperture size I accept that these are an awful lot of questions however the good people of this parish came good when offering advice on how to capture images of the moon and stack them to get the best image I could. Cheers muchly. :-)
  4. Thanks for the advice which I have used to try and improve on my images. And I have to say that they look more natural and far less pimped up and over pixelated.
  5. Yes, i did use Register and I do find the white edge frustrating. Could you please tell me how I can reduce the white edge?
  6. Well, I'm not one for giving up on my quest for cheese. About a month ago I took the advice from this discussion and put it to good use. I was also lucky with the aid of a cold weather snap, so I took a mixture of RAW and MOV files. It took a lot of guess work and faffing around but I think I finally hit on the right combination of procedures in the image processing to get two shots of the moon that I am really pleased with. I could have read the manual, but where's the fun in that? Enough of all that, I would appreciate any advice on how I could improve on my second attempt at hunting for cheese, both blue and grey. :-)
  7. Ten years ago I would not have been able to afford any equipment that would produce an image of the quality I took with a single camera mounted on a tripod. Just 10 years ago a top of the range Nikon D3 dSLR would have set me back £4,000 and that was before I added a lens of 800mm which only became available in 2013 for an eye watering price of around £13,000 extra. I have no idea about telescopes, mounts and such like but I'm guessing that the kit needed would have cost quite a bit too. Go back another decade and I'm guessing that my pockets would have needed to be even deeper to get an image of comparable size and resolution. Would it be too much a stretch of the imagination that organisations like NASA or universities would have been able to produce such images? Yet today, weather permitting, if I tried a bit harder I could produce this image hand-held from a camera that has never seen or been near a telescope. I wonder how much it would have cost to create the same image in size and resolution? Obviously there is technology out there that can blow my image out of the water in every respect, but in the 60's and 70's would the same image have been classed as cutting edge?
  8. Having a stab at photographing the moon this week got me wondering about how much technology has advanced, and so quickly in a very short space of time. If you could step back ten years, what sort of technology would have been needed for someone to take an image of the moon of at least the same quality and how much would it have cost? The image could either be in a printed format or on a TV screen or monitor. And if you were to jump back a decade at a time to the 90's, 80's, 70's and so on, what technology was available then and how much would it have cost to produce an image as good a,s or as close to the image I took this week?
  9. I had another go with choosing only 100% best images and just 5 stacked images. This is very much a work in progress and I would like to thank everybody for your help and advice. For my last test image, this time I only chose the 100% best images and limited myself to the best 5 to stack. I am very happy with the final result. Next time I will know what I need to do to capture the best results. I will use my len's sweet spot for focal length and do a mixture of RAW files and Mov files at a resolution of 1080p rather than 4k. I will also ensure that the tripod is fixed rigid so that I don't add any movement into the mix. All in all this has been an interesting learning curve which has demonstrated to me that even 5 images stacked creates a far better final image than just a single image. Cheers all. :-)
  10. OK, just got in from a good evening of climbing and had a chance to put everybody's good advice into action. I used PiPP to prepare the 40 RAW images I took last night and then used Registax to stack the images together. I must say that I am more than impressed with the lack of excess noise in the form of weird patterns. However, is it me or is there a sort of shifting/double imaging going on or is that to be expected? On the whole, what do you chaps think of my second attempt at stacking images?
  11. Hmmmm. To be honest, I am not a fan of these wavelets as they seem to introduce strange noise and patterns within the processed image. I'm no Pixel peeper by any stretch of the imagination but I'm not a fan of over edited images. I'm getting the impression that you use the wavelet sliders exceptionally conservatively? It's not exactly like using sharpen and noise reduction in Lightroom.
  12. Thanks for the advice about converting a Mov file to an AVI file. ANd as for the ISO, unfortunately I can't go below 200 however I shall keep trying to improve. Cheers
  13. Hello Last night I took some shots of the moon with my camera on a tripod. The plan was to install some software and then stack the images. However I have discovered that things are not that simple and I would very much appreciate any advice to get a good image of the moon and all the lovely cheese on it. I downloaded Registax but it kept crashing. I initially used RAW images then I had to convert to TIFF files but the software kept crashing. In the end I got passible results with only 4 images. Any more and the software crashed. Would it be better to actually take a movie of the moon rather than taking still images in the hope of stacking them? If taking a movie is the way to go, then what file format should I take to make the movie? I have a Panasonic GH4 and a 100-400mm lens which means that I can get 4k movies of all that lovely cheese. Cheers muchly Here is my attempt at a single image And my stacked image of four shots
