  1. Thanks Peter, that's what I thought might be the case. Still, it would be a useful feature.
  2. I have a quick question for anyone using a Celestron mount with the Nexstar system. Is it possible to reduce the goto speed? Though I have had no problem with adjusting the rate at which the mount moves when the direction buttons are used the rate adjustment does not seem to affect goto speeds. I've had a look through the manual but either I've missed it or the option isn't there. Much though I enjoy seeing the mount sprint off to it's next location the noise is going to draw complaints from the neighbours at some point! Tim.
  3. I'm hoping there will be some CGEMs on show at Astrofest, the wife has agreed to an upgrade from my overloaded Vixen Sphinx SXW and I think the CGEM will make for a good choice. The decision for me rests largely on it's comparison to the EQ6 pro as that is the other obvious option. I'll be picking brains this weekend hoping to make a well informed decision. Thanks for the review Nick, it was both informative and timely!
  4. It's been a while since I posted a new image here, to long I think but then it's been an unproductive few months mostly spent trying to get to grips with guiding. Last night however I managed to get out and despite the moon get a couple of hours in on M81 & M82, 24 x 5 minute exposures. Stacked in Iris and processed in Pixinsight.

  7. Looking at the photo again there is nothing to identify the people in as as astronomers, it's just a photo of someone pointing a laser at a bright object in the night sky, that object is not identified, maybe it's a planet, maybe it's a helicopter. The article clarifies the legitimate use of the laser pointer in astronomy regardless. On a related note my society has had some discussion lately regarding using green lasers after some fishermen got in trouble whilst scaring off ducks. It's a bit depressing that people are feeling threatened for using a legal tool for a legitimate purpose.
  8. To be fair the first line after the bolded sections is 'Astronomers first used them to point out celestial objects', right next to the picture of astronomers using one. You'd have to be pretty good at jumping to conclusions, or at least not have read further than the headline to read it as vilifying astronomers.
  9. This will be my third year, I commute into London anyway so it's not far out of my way. It's a bit pricey for both days but I've always enjoyed it. My family have now learned to give me an astrofest budget as a christmas present!

  11. I found my missing bit! So here it is without the cut out, a bit of a gausian blue applied and the color left in. Click for the full size. Next time I'm going to have a go with the barlow and concentrate of specific areas and go for more frames. Lots of learn! One more.... the same night, but a stack of 30 raw format images taken with the canon 1000D on the 250mm reflector, stacked in registax and deeply over saturated to bring out the surface variations.
  12. That looks identical to the ones off my old 250mm Orion Optics reflector. If that's the case then give me a message as I can probably help you out. my rings are serving as a scope rack in the garage and the clasps are sat in a pot doing not very much.
  13. As a linux guy by trade I should really be flying that flag, but frankly I don't use it for anything other than running servers even outside of my professional life, for astronomy and especially imaging it's not much help to me, but you can't beat it for running web servers. I don't have a mac because they are annoyingly expensive. I love the ability and flexibility of the PC platform regardless of the OS. I can knock up a machine from spare bits from the cupboard, mix and match whatever I want or throw together something new for cheap from components bought online. I have more than enough knowledge to keep my machines running quickly and reliably and I think I've only seen one virus actually get as far as being picked up by my antivirus in the last few years. If you need free software than windows sports a wealth of it, most major open source projects come with windows ports these days, not targeting the largest user base would make little sense. I can't think of any software for Linux that does not sport a free windows version or suitable alternative. As far as a desktop operating system goes Windows does everything Mac or Linux can. It's as slow or as quick as you want to make it and security stands in direct relation to how sensible you are. Mac and linux get a pass on that through not having the vast majority of the worlds user base, if your aim is to create botnets or farm personal information then targeting anything other than windows makes little sense.
  14. Your off to a great start! I mentioned in my thread that I used Windows live photo album to stitch mine together, it's worth a go. You just select all your images, right click it and select 'create panorama' . You don't need to tell it anything else, it will put everything together for you in the right places and sort out all the seams.
  15. I have a cunning plan to fix the missing bit by completing my full frame avi from the 1000D in regiistax and cutting out the missing bit, it'll be lower resolution but that bite is nagging at me. I also have 60 full 10mb raw images, I'm wondering if I can get those to stack in registax and pull my missing bit from there...
  16. A couple of images form last night, the first one just made me laugh. I was testing out EOS movie record with the Canon 1000D with the though of doing a full frame avi stack on the moon when I saw this : The second image is my first attempt at a mosaic, I used an SPC900NC webcam on my 250mm reflector. It took a total of 27 captures to cover the moon, each was about 1000 frames. These were stacked in registax and then I spent hours carefully aligning them all in photoshop. Then I though, 'Windows Live photo album has a photo stitch tool, I wonder if that's any good?' Yeah, it is, it did a better job than I ever could in about 3 minutes, it even corrected the colour across the images and blended all the seams. I should mention that I had to reverse the scope about two thirds of the way through this and the camera got moved, so those images are at an angle to the rest and it still got them right, amazing software. You don't get any bonus points for pointing out that I missed a bit , It's the shadow of a passing UFO I reckon. (there is an even more huge version of this, I'll work out somewhere sensible to host it in the morning.

    A lucky shot!

  18. I've got about 17gb of avi files from the moon last night, hopefully they are of decent quality and I can start putting a mosaic together this evening. I've not tried lunar imaging with the webcam before, and I certainly didn't go out with the plan of doing all that!
  19. I also use wordpress, it's very simple to get going and the documentation is clear and easy. I am an IT engineer by trade so I'm pretty technically minded but I've done little to nothing in the way of HTML or web design so it certainly suited my needs.
  20. Definitely on my to-do list, it can't be more tricky than a webcam modification, at least I don't have to solder anything!
