  1. All valid points. As rto the first, I should have stipulated arc-saconds but didn't as I just assumed everybody used them as it's the only way to get meaningful data unless the guide setup is identical in every respect to the imaging set up. As for guide resolution and RMS, very good points. For anyone still reading this thread, could you please include your guide resolution as well. If people only have guide logs, that's also fine. I'm looking specifically at data from NEQ6/EQ6 mounts at the minute, though by the end of the project, the results will hopefully be transferrable to all Synta style EQ mounts.
  2. Ladies and gents, I need your help: For all owners of NEQ6/EQ6 mounts who image, would you mind sharing your guiding graphs with me? It's for a univesity project so I need guiding graphs from an average night's imaging with RMS displayed. If you are having issues, an older graph is fine, providing it displays the type of guiding you usually achieve. I also need to know whether you are running the original gearing or have the belt mod. No other data, personal or otherwise, will be collected. Any help you lot can give me would be greatly appreciated. Either post them here or PM me. Thanks in advance. Tiny.
  3. Ha to R, SII to G and OIII to B. It's a shame because this target can look stunning in the Hubble pallet, but 600s exposures just weren't long enough to pick up the sulphur. And although it's 18.5 hours of data, I honestly think it needs a lot more. Maybe double that.
  4. Spent a few nights on IC410. Unfortunately, there seems to be next to no SII around, at least not without going to much longer subs, so Ha is mapped to red in this. Ha; 67 x 300s OIII; 69 x 300s SII; 43 x 600s
  5. You're not the first person to mention that. A slightly warmer tone might improve it a bit. With regards to the histogram, the only way that I can see it being misleading is if the final image were composed of other images that had been only slightly clipped. If it was anything more than that, the histogram would show corrupted data. Having looked at the different layers used in this, none of them display clipped histograms. And I honestly can't see it. Maybe I should get my eyes checked? If one person says it's clipped, an argument can be made (and has been), but if others are saying the same thing, perhaps it's time to turn the gaze inwards.
  6. As is mine, but more importantly, the histogram shows that it is not clipped.
  7. I think that that might be your monitor as it looks fine on mine and the histogram shows no clipping.
  8. I revisited M33 over the last couple of nights whilst I was trying to sort some guiding issues out. L: 57 x 300s R: 25 x 300s G: 25 x 300s B: 25 x 300s Ha: 15 x 300s All at 200 gain, offset of 65 and temp of -20 C with the ASI 178 MM-Cool and the Altair 60 EDF.
  9. I'm after an old unmodified EQ6/NEQ6 mount head, to borrow for a couple of months for a university project. It doesn't matter if it's broken or not working. I basically need one to strip down, measure certain parts and examine wear etc. If someone has one that is laying about doing nothing and is willing to lend me one, I'll pick it up, drop it off and, if it's a working head, I'll clean it up and re-grease it etc before reassembly. Failing that, if it's a dead one and you want rid, I'm happy to contribute to the beer fund. Cheers Matt
  10. Don't know if it's just me or maybe my laptop, but it looks kind of dark. A boost to the midrange maybe?
  11. This is by far the biggest selling point for robotic focusers. A few years ago I got an old Robofocus as part of a used bulk buy and it has made life so much easier. If I had to buy one brand new though, I'm not sure that I would as they are very expensive to set up, as Olly said.
  12. The EQ5 should handle an 8 inch reflector for visual observing... just, but as others have said, for imaging, you'll need a smaller scope. I've imaged with the 130 PDS (Newtonian) and the Altair 60EDF (refractor) and my advice would be; when you come to decide on buying a scope for imaging, buy a small refractor. They are just easier to use and noting ever really goes wrong with them. They do have a higher capital outlay, but your saved time in the long run is worth more than that initial outlay. For observing, an 8 or 10 inch Newtonian will deliver stunning views.
  13. This is absolutely spectacular. And I agree with everyone else; the green works and gives it more depth.
  14. I've imaged this before with my old rig but thought I should try it with the new 60 EDF. There seems to be less detail, but overall I think a better image. The bubble is certainly more prominent, though that is due to having a lot more data. ASI 178 MM-Cool Altair 60 EDF with FF Altair 7 nm Ha and 6.5 nm OIII Ha; 50 x 300s OIII; 66 x 600s T; -20 C Processed in DSS and Photoshop CS5
  15. Using the Altair Astro 60 EDF scope and the ZWO 178 mm-cool camera.
