  1. Finally found time again to process some more data that I'd captured on holiday in rural Wales (after growing ever more frustrated trying to image in London). Only had time to capture 8 x 60s and 1 x 240s subs with the usual set-up: Opticstar ARC102-S + unguided eq5 + canon400d. Here it is, my first attempt... Let me know what you think!
  2. Ahhh right, I hadn't come across this definition of noise before. I quite like the idea of picking up the occasional gamma ray, terrible for the sub, but satisfying to see when you think of how they come about Living in London, I can definitely sympathise when it comes to light pollution, especially from the new broad spectrum LED street lighting that they seem to be installing everywhere. Luckily they aren't too keen on making the transition in my area but it seems to render most LP filters useless. That being said, narrowband filters should still work on LED lighting to some extent right?
  3. Thanks for all the info pyrasanth, I'll put the Bracken on the to-buy list long with Making Every Photon Count, which I've also seen recommended quite often. Wrt. using narrowband filters to reduce noise, I thought noise was an unwanted effect of the electronics being used, in which case the filters wouldn't reduce noise but only light pollution and unwanted wavelengths right? Again, I'm not too savvy with this, so let me know if I'm thinking about this in the wrong way. I've heard great things about the RASA and if that image above is anything to go by, it deserves the praise. Wonderful image
  4. thanks for the advice pyrasanth. I'm only imaging with DLSRs for the time being, though a CCD might on the horizon after I have a little clear-out. I tend to use a UHC filter for when the light pollution gets intolerably bad (nearer the horizon etc.) but it doesn't work so well on some objects. A decent lp filter is on the Christmas list, but I'm told that they can be quite hit-and-miss, dependent on the type of street lighting nearby. I'll certainly give the IDAS a look though. I'm still trying to get my head around S/N, but I thought it scaled by the square root? Surely longer exposures woul
  5. Thanks for the comments all! It was nice to finally get an image out after such a steep learning curve. Thanks Reggie, I can't remember exactly but I think the subs were 4x60s, 8x90s and 2x120s. Bit of a mixed bag, but I was trying to see how far I could stretch the subs given my fairly poor alignment. I'm ashamed to say I didn't take any darks/flats...still all seems like witchcraft to me. Cheers angel, being a student the equipment is all on a fairly tight budget. The scope was an Opticstar ARC102 f/6.6 (great scope for the price) on an eq5 with dual motors (unguided). The camera is an unmod
  6. Hey all, finally got around to processing some data I'd captured on a recent holiday to rural Wales (slightly more astro-friendly than London). Not too sure what I'm doing when it comes to post processing, so any advice is greatly appreciated. Happy to send over the data if anyone wants to mess around with it, see what comes out. Here it is, my first attempt: (had to rescale image to 1MB posting limit). Cheers, Jay
  7. Cheers for the map Paul, I'll give it a when this cloud decides to clear. Okay, I'll get hunting for a UHC. How much use are narrowband filters?
  8. I've only recently moved on from the "point and hope" method. Star hopping is certainly working better, managed to finally catch a glimpse of M94, M3 and Cat's Eye last night (3 in one night, a personal best ). A dark sky might show you more Paul, but what about the thrill of "is that a smudge or a galaxy?" Cheers for the list DD, should get a go at ticking a few off if this weather holds . What would you recommend filter-wise? I've tried a SW LP filter, but it didn't seem to do much for my skies. Probably even less now that the local school has decided to leave their LED floodlights on 24
  9. Might have to dig out the soldering iron again...that rarely ends well. Are there any benefits to controlling the camera through APT as opposed to via an intervalometer? I've noticed that my laptop has a D15 serial port, not the D9 for the cable from Andy's website trip to Maplin methinks.
  10. Also, could someone explain how this is supposed to work...I need an rs232 cable with a 2.5mm jack on one side right?
  11. Cheers guys. Once again, buying more kit seems to be the only option
  12. Hello! Haven't had much experience with this program, but it seems to be absolutely fantastic. However, I've encountered a bit of a snag. Everything works great...so long as I don't try and take a bulb exposure, at which point the software thinks the camera is capturing but the camera doesn't respond at all (no shutter sounds etc.). It's happy taking up to 30s exposures without bulb, but refuses to take any length of exposure on bulb. Any help appreciated! Jay
