  1. November this year was brutal for rain and snow here in Ottawa, and December has not been much better clear-sky wise. Cold I can take. It's all this damn waiting around to justify my recent expenditure on this kit to my wife, who already had her doubts about my sanity concerning the 20 years of dob reflector use. I told her that this new bit of business would allow me to get back in the house relatively quickly after initial set-up-and the images! Up to this disappointing point, she hasn't changed her mind about my mental health. And if I drop into bed like an icicle falling from a roof one more time at one o'clock in the morning, it's my physical health I'll have to worry about!
  2. Okay, thanks for the added info. This may be something to look into in the future when I get some experience behind me. I'll let you know how it goes tomorrow.
  3. All you've said in the first line is correct. I don't remember exactly, but from the initial set-up I couldn't get PHD2 to recognize the others, so when it recognized GPINT I figured that must be the one, though to be frank, I can't say for sure that I tried On-Camera initially or not. I can see that 'On-Camera' is in the mount selection, and I have now chosen it. I hope you will indulge me in one (at least, haha) more thing: I don't know if I am using EQMOD (how do I check, if necessary?), but that is not on the list of mount selections, so can I assume that I am okay as is? I was wondering if testing could be done in the house without having to go through the entire set-up outside first. I definitely will try it tomorrow in the light of day. I'm this close, kens, I can feel it, haha. I think I have everything else figured out, at least well enough to start gathering some worthwhile data. All that's left is Adobe PhotoshopCC, and that subscription is my Christmas present, though I'll have another learning curve there, for sure. If this works out I am in your debt, you've been great, thank you.
  4. Here is the guide log. I assume by 'attach' you mean to upload it here. I've just found, in the PHD2 manual, advice to try the Manual Guide in the Tools menu to see if the mount is recieving pulse orders. This sounds like the way to find out if there is actually a connection or not. Unfortunately, there seems no break in the weather for a few days.

  5. Having no previous experience in guiding (I've had only the benefit of a dob reflector for twenty years), I don't believe now that I have a 'previous calibration' remembered. In fact I think the few times I have tried to use it once getting the new kit up and runing I assumed that it was working when in fact it was not, and the 'decent' images I was getting were due to good polar and synscan 3-star alignment (and quality HEQ5 mount), if that makes sense. I tried imaging the Pleiades a week or so ago with 180s exposures and managed to acquire 32 out of 65 that did not have star trails. The final image was 32x180s at 1600iso with no darks, lights or biases. In studying it again I see that there is still some trailing, and the stars don't look crisp. I adjusted it somewhat in DeepSkyStacker, then played with it for colour and contrast in a run-of-the-mill photo editor I have, as I am only getting Adobe PhotoshopCC for Christmas. I'll post it here for you to critique. And by the way, I did have time the other night before the weather closed in to try the 'Shift-click to force calibration', but with no positive result. The suggestion of calibrating the mount seems to be the only thing left I haven't done, and that routine is at the mercy of the weather, which doesn't look good for the next few days. The routine is to slew near the intersection on the meridian and the equator, hit Loop, then Tools> auto select star. Then hold down shift and hit the green guiding button. I don't see how this is any different from what I was doing before, but I will try it. Anyway, here's the image.
  6. Just checked that setting and it is in auto, thanks for the suggestion. It seems I need to calibrate the mount to correct this problem, as has been suggested, and of course I'm at the mercy of the weather to attempt anything further, which looks like a couple more days wait.
  7. Yes, I double checked just now and guide scope focal length and pixel size of the CCD guide camera are set correctly. Thanks for the suggestion.
  8. Duly noted. I wait with bated breath for the next clear (cold!) evening. It would be more bearable if I'd bought this kit earlier in the year instead of late October; as it is I'm spending an awful long time out in our typically chilly Ontario November/December evenings trying to get this thing 'off the ground', so to speak.
  9. My attempt to select a star (several, in fact) manually this evening in case I was guiding on a hot pixel has proved fruitless. Unfortunately, clouds moved in soon after and I could not do as you advice in calibrating the mount, which, much to my surprise, seems a necessary step to proper guiding? Every time I think I've got all the info I need something else crops up! It seems, according to the latest forecast, that I may not get another chance to try this for a few days. I doubt there is any other problem, i.e. the mount backlash, etc., because I have imaged up to three minutes successfully, though not spectacularly, with only good polar, and three star, alignment from the synscan (HEQ5). I feel on the verge of cresting that big wave to the kind of images I dream of, if I can just get this guiding issue out of the way.
  10. I will try as you suggest. I forgot to mention that when I put the mouse on the green calibration button to start guiding, a window pops up and says 'Shift-click to force calibration.' but I hesitate to try this, as I'm not sure what could happen. Are you familiar with this? (Thanks, by the way.)
  11. After building a dark library, starting looping and then auto-selecting a star, I begin PHD2 guiding. After five minutes or so the yellow cross-hairs vanish from star selected, the green Start Guiding button goes off, and this message appears: RA calibration failed, star did not move enough. I also select Display Graph to follow the guiding parameters but there is no action shown, just a dead graph. Please, what am I not doing right?
  12. I retained my original trusty stock Canon T2i as an all-round camera and purchased a T6i to modify for this new hobby. Perhaps I could have done it the other way round but the T6i has better noise reduction. I doubt that the 18MP to 24MP jump makes much of a difference, but the T2i has a half million or so clicks on it and it was a concern that it might not hold up much longer through these Canadian winters, though it has worked steadily through -25C temps on many occasions in the past.

    Let's see your 1st DSOs

    My first, and only, two. M31 (20x30s lights, 1600iso) a month ago, and M45 (16x180s lights, 1600iso) a few days ago. My scope is 900mm with a .85x reducer/flattener, so M31 is mostly core, but the Pleiades fit very nicely. No flats, biases or darks, both worked somewhat in DeepSkyStacker, and the Pleiades falsely coloured in a Microsoft photo editor, because my wife says I don't get Adobe PhotoshopCC until Christmas! I did a lot of preliminary groundwork before attempting anything, and I'm very proud of them.

    Hell and The Devil in Astronomy?

    There is little doubt in my mind that hell is a White House, and the devil resides within.
  15. If you go with an IDAS clip-in for prime focus imaging like I did for my Canon T6i, keep in mind, if you also plan on using camera lenses for wide-field imaging, to make sure that the lenses are compatible with the clip-in. My 50mm and 50-250mm EFS lenses will not fit with the clip-in in place, and I now have to purchase a 2" LPS filter or buy new EF lenses. I was told that trimming off the superfluous flange on the EFS's will allow it to fit, but in trying this with an old beat-up EFS 50mm, I found it did not work (and as a millwright I know it was not because of anything I did wrong). Just curious r.e. your comment about not modding the DSLR. I think you may be limiting your ability to capture the widest possible range of colours without this mod. I checked out the tutorials and was ready to give it a go until my brother, who has worked all his adult life repairing electric and electronic instruments and equipment, told me he had done several over the years, so I jumped at the chance to have it done by a pro I trusted, and at 1/3rd the price! Perhaps a member of this forum has a connection to pass on? Just saying.
