  1. Hi everyone, This is my very first proper attempt at widefield using a nifty fifty lens on a Canon 1000d mounted on a tri pod. Exposure time 8 seconds, IS0 800, Aperture F/4.0. For the Orion shots, I took 15 lights, 6 darks and 4 bias frames. For Pleiades, I took 12 lights. I used the same number of darks and bias shots as for Orion. Images stacked in DSS using default settings and processed in GIMP. I think both images are slightly out of focus and I'm still not sure what I'm doing in terms of processing. It's a start. thanks Pete
  2. Thanks again John. As a beginner, that's just what I'm looking for. My plan is to have another go at Orion sometime, may be tonight if it is clear. Cheers Pete
  3. Thanks John, I'll try that and keep exposures relatively short at 8 seconds or so. By the way, do you happen to know if there is a general guide (or link to a thread) to exposure times versus aperture settings for the nifty, perhaps with different ISO settings. I'm finding all of this very confusing Cheers Pete
  4. Wow, amazing, just amazing. Did you use APT (or some other system) to take all those images? For such a huge amount of images I would imagine using an hand held remote would be out of the question. How long did you pause between taking each exposure? Thanks Pete
  5. Hi John, Thank you for your advice. I'll try again but with much shorter exposures (8 seconds). I forgot to mention previously that I had set the aperture to f1.8 and the ISO to 800. Are these settings still ok for such short exposures? I'll certainly take a look at the thread you mentioned. Thank you. Just want to say that apart from the Nifty which cost £80 new, the only other expense to use the camera on the tripod was the cable remote at £6.50. I did buy a short dove tail at £12.50 and a two-way 1/4 inch screw at £4.50 but those are for mounting the camera on the HEQ5 mount. Cheers Pete
  6. Hi James. I need to do a bit of reading and then may be take some more photos. Thanks for your help. Pete
  7. Hi John, Took my first ever set of photos this evening (Canon 1000D on tri-pod, with Canon 50mm f1.8 lens. Exposure controlled using remote release). I took 10 lights at ca. 30 seconds each, and 5 darks at same settings. I've done a quick process in DSS but not sure what to do next. I've saved the DSS image as a TIFF file but it's big at 58MB. I've run it through GIMP played a bit with the 'Curves' (again, no idea what I'm doing) and saved as JPG, attached below. Looks like 30 seconds was too long an exposure as there are star trails. Sorry this is a poor image. Any tips or pointers to tutorials as to how to process the files? Many thanks Pete
  8. Hi John, I think I've solved the problem ... just waiting for a part. Sorry about moving off topic. P
  9. Hi John, My 15cm dovetail has just arrived from FLO. I'm probably being a bit dim but I can't figure out how to attach the camera to the dovetail. I have a spare camera screw that has a wide knurled bit at the end but when screwed into the bottom of the dovetail, it doesn't lie flush with the bottom. The dovetail doesn't sit flush. Should the screw just be a screw? Thanks Pete
  10. Hi John, My kit is a 1000D camera with standard zoom kit lens; HEQ5 Pro mount (with SW200 OTA). Also got a 150PL scope and tripod/mount with motors. Dovetail currently in the post from FLO. Just thinking ...which is dangerous for me ... why do I need a ball head mount? Couldn't I just use the RA and DEC axes to rotate the mount (and camera) into the required view? Thanks Pete
  11. Hi John, Now that is a great idea. I do have an HEQ5 Pro mount but I don't have a dovetail to standard camera mount connector thingy. I guess I could buy such a thing, or perhaps make one. Could you recommend a site where I could get one from? Many thanks Pete
  12. Hi John, I knew I had forgotten to ask something ... I'm planning on using APT to control the exposures. What sort of time delay do you recommend between each of the 30 second exposures? Would 10 seconds be ok? Thanks Pete
  13. Thanks John. I'll do a G-search for raw viewers on Win7, see what comes up. Pete
  14. Brilliant John, many thanks for sharing. Definitely going to try it out. Some quickie questions ... Are you setting the camera to Shutter priority mode or Manual mode Is there a RAW viewer for Windows 7? When you say 'stop down the lens' are stopping down by 1 full stop in aperture or using exposure compensation? Many thanks Pete
  15. Hi Steve, Just downloaded APT, installed on the lap top .. plugged in the 1000D with the ordinary USB lead ... and proceeded to take several photos of the rain using one of the APT plans. Just brilliant!! I love this plug-in-and-play stuff. Next job ... learn how to use APT and then hope for some clear evenings. Cheers Pete
  16. Thanks for the link Steve. Phew, wasn't expecting the DSUSB to be over 70 quid in price, plus another £6 for the cable to the DSLR. I might have to look at alternatives. Pete
  17. Thanks. I didn't realise one needed a special cable. Any idea about the type of cable? Not tried the free APT yet. Might just do that. Does that need a special cable too? Pete
  18. Hi, I'm trying to set up the DSLR Shutter software to control my Canon 1000D. I've connected the 1000D to the lap top with the USB cable that came with the camera, but every time I start DSLR Shutter there is an error message about not being able to detect a USB port. I've tried all the USB ports on the lap top. All of them work as the computer can see the camera (and all the photos on the camera). Any suggestions as to why DSLR Shutter can't connect to my 1000D? Many thanks Pete
  19. Hi everyone, Been looking at using Rawtherape to process RAW images. Has anyone any experience with this software? Any hints or tips. Many thanks Pete PS: I'm just getting into RAW imaging, could anyone point me to a tutorial or to a guide as to how to process RAW images (not astro-images at the moment, just ordinary ones ... I hope to 'graduate' to astro-images soon).
  20. I have two note books. An A4 notebook that I record the session details, like date, time ... seeing etc but also equipment settings, problems ... how to do things ... tips and tricks. Where possible I print out a photo captured using the web cam and stick it into the notebook. I also have a small note book that goes in my tool chest that contains all my scope tools, eye pieces, spirit levels etc. This note book has extracts from manuals (e.g. how to align using 3 stars, Synscan menus etc) and also capture settings for various objects using SharpCap (Mars, Saturn etc). The reason why I have this smaller book is no matter how many times I set up my scope, I always forget how to do something ... for example, how to find a particular menu option on the handset. Works for me. Pete

  23. Hi, Great post. I have a HEQ5 pro mount and it took me quite a few sessions just to get comfortable with man-handling the mount to my observation site, fiddling with the legs ... getting it horizontal (a digital spirit level is the bees-knees for this task) ... setting up the tray ... attaching the scope ... but it is worth it in the end.
