  1. I've always wanted to do this modification. But now winter is upon us and the fun stuff is coming out so I finally decided to give it a serious attempt. I picked up a faulty 350D on eBay for £15, tested it and found that the fault was nothing more than a dud battery. I ripped it apart and carefully dismantled the sensor. The coverglass came off very easily with a razor blade. Things were going well until without thinking I went to wipe some of the dust off the surface and hit a gold wire. Ok, so I gritted my teeth, picked up another sensor on eBay for £20...Only this time I cut the razer in half and stuck the two sides down so they covered the amazingly delicate gold wires. Absolutely no problems from then on out. I practised various techniques on the broken sensor and found the wooden tool I made worked best. I used the handle of an old brush and carved it down to a sharp flat blade about 3-4mm across. It took about an hour to completely remove the material. Right now I have the camera in a semi-assembled state for testing. I've taken a few test shots, but without a CF card right now I cannot upload them just yet (That's another eBay order on the way). There is a very thin line of colour on the top and bottom of the images as the razer guides overlapped a bit preventing the removal of a mm or so of the matrix. I don't mind that at all. I can see though I have a bit of cleaning work to do in some places so I'm about to start work on a dustproof glovebox for a second disassembly and cleaning. It's a lot of work but I'm having so much fun.
  2. Thanks Romeo, I'll start work on a new design. I think I'll make it simpler while I'm at it, maybe only 3 filter holes with shorter 'ears'.
  3. I've just finished designing this low profile filter 'wheel' for EOS cameras. I've never used a 3D printer before. It would be helpful if someone could take a look!
  4. I've landed a decent job with a broadcast hardware supplier in West London and I will be moving there at the end of the month. The chances of being able to get any decent shots in my free time however is looking 'dim'. I'm told the sky is so bright it can be hard to even make out planets...! Would moving to monochrome narrowband imaging be a workable option? If so, what filters would I require? Otherwise I'm just going to have to sell my kit and move on to armature radio astronomy or something.
  5. I recently posted a topic asking if opening a brick and mortar telescope shop was worth it. I had a lot of helpful feedback and the answer was a clear "No". Well I have another idea I'd like to run by you all - Renting telescope equipment. I think it's an area that is currently poorly served in the indistry. The few companies that offer such services have very limited ranges, and mostly consist if basic dobs. My unique selling point will be holidays - say you're traveling to Spain and would like to take some astrophotography images while you're there, but you're put off by the idea of lugging your EQ6 Pro and 10 inch 'scope with you. Well, what if you can go online a week or so before your flight, pick what equipment you want to rent and chose to have it delivered to your hotel. Then when you arrive the equipment will be there waiting for you, no hassle (at least until you come to setting it up!). Once you're done the equipment can be collected and you can fly home with all your pictures. Any feedback? Alan.
  6. After finding it frustrating not having a telescope shop near by I have been putting together a proposal to open a shop myself. I'm going in at the deep end here, and I could use some advice! For a start I'm only 22, and I don't own a house, so getting a business loan is going to be blumming difficult. At least at any decent APR. Secondly I'll need a supplier or two, finding one for the UK is like panning for gold. Dose anyone out their own a telescope shop? If so, I am looking to for your wisdom! Regards, Alan.
  7. Well this is embarrassing. I must have typed up the wrong info. A recheck says that the actual time is Sunday, 12 May 2013, 19h 39m 32s
  8. I assumed the whole UK, but the image is based upon my location in South Wales.
  9. I've been doing some research using calsky and I found that a Falcon 9 rocket is due to transit the moon from the perspective of the UK on "May 1st, 20h39m37.08s" It should last about 40 seconds. I don't think anyone has imaged a Falcon 9 transit yet, but if the launch is on time then we should have a decent stab at it! Alan
  10. You'd be at the limit of the LXD75 with the 150p, the 200p is too heavy. Nether scope will function well for astrophotography unless they are mounted on a HEQ5 or better. If so the 200p is a superior scope.
  11. I've just picked up a h-alpha 35nm filter. I will be using it on an unmodified 550D (T2i). My question is what can I expect to get out of this? I live in a fairly light polluted area so I'm hoping that I'll be able to take much longer exposures of things like nebulae and galaxies without the images bleaching out. But I won't get my hopes up too high yet. Any input would be very much appreciated. Cheers, Alan.
  12. It's something that really confuses me. My HEQ5 pro has come with only a serial cable to connect the mount to a PC. Serial ports haven't been used for over 10 years now. It's disappointing that I have to go out and buy a USB adapter as if I'm trying to use some ancient hardware. It can'be be that hard for them to upgrade the mounts to include a simple USB port can it?
  13. Dose anyone around here hunt asteroids? If so - how, what, where? Cheers, Alan.
  14. I'm sure it was connected...Hmmm. I'm using a Orion star shoot autoguider with a HEQ5 pro. perhaps the ST4 cable is damaged.
  15. It was fairly clear last night so I went out and set up my imaging rig. It was my first time trying to auto guide with PHD and my HEQ5 so I'm probably missing something. I started up PHD, configured the refresh rate, got the camera focused and selected a guide star - but the PHD target icon was still grayed out, so I couldn't get the software to start guiding. I fallowed the "Important instructions" to the letter but the last step still wasn't possible. Am I missing something or is this a bug? Cheers, Alan
  16. Ahhh! Thanks a lot! I'll try that next time I get a clear patch (Next year maybe? Aha) Alan.
  17. Tonight I had a 2 hour window of clear skies to test out my new HEQ5 pro. I set the mount up so it was perfectly level, used a true north compass to get the mount pointed in the right direction and plugged the mount into my power tank. After turning it on I got on my knees to start polar alignment - But the polar scope was way too bright, and I just couldn't for the life of me see polaris. By the time I gave up it was already starting to cloud over again, so I packed up feeling a little bit disheartened and headed home. Dose anyone with a HEQ5 know a way of making this 'work'? Cheers, Alan.
  18. Well I did it. I've hacked off about a cm from the focuser as planed. I also had to remove the gear track and glue it back on further up. All seems to be working fine, I'll test it out when I get clear skies.

  21. I think you can install magic lantern on a 1100D. It's free and comes with an internal invelomitor.
  22. I've got both but still waiting for clear skies to test. D
  23. I've noticed to my dismay that I have once again picked up a scope that won't reach focus with my 550D. I'm thinking of taking a hacksaw to the end and removing a cm or so so I can get enough inward travel. Any reasions why this may or may not be a good idea? I figure if I mess up I'll just need to buy a few one anyway. Cheers.
  24. Some good posts. It's worth noting that I wasn't trying to compair "who's better" - just who on adverage had a better understanding of the science behind imaging.
  25. I've noticed that ameture astrophotographers seem to have a far greater understanding of optics and cameras than most professional photographers. It has only recently became apparent to me after seeing some supposedly top photographers really struggle to understand how I was able to take some crude images of the andromeda galexy "with mirrors" aha. For them, there isn't any pressure to understand much about optics or how their equipment works, they just throw money at brands and gimmicks and use them to take pictures of skinny naked woman. Whereas astrophotographers need to get their heads around so much in order to get that perfect final image. Maybe it's just me.
