  1. If you have a uhc try that. i thought it helped last time i tried it.
  2. Same here and even when i could see them they were all over the place.
  3. Looks like AS hasn't aligned them quite right. I tend to use around half a dozen manually placed points on the edges of whatever strong features I can see within the disc. Don't know if that's the best way but seems to work. As mentioned above maybe pick different point size. i last used 48 and that worked out.
  4. Fantastic set of images, and very very useful. Thanks!
  5. Much better than my first go at Mars. A bahtinov mask will improve the focus though, which should help things. It could just be the seeing on that night though, as that makes a big difference.
  6. It may be new to NASA but I think I have an idea?
  7. Nothing here for days I'm afraid. I'm still waiting for a handle for mine as they seemed to be out of stock when I ordered. I hear a chap in the Derby area may have a garage full though?
  8. Yes if you've got a few video files then add them to pipp and there is an option on the first screen "join mode" that should then put all the images from those into one output file that you can then put through As3 to select your best from. Select the tick box for planetary. I've only merged a set of files that are about 15 or 20mins apart in pipp and that seems ok but 2 hours would be too much. There is another piece of free software winjupos that can derotate and stack separate files and I think I read you can probably get about an hours worth on mars with that, but I've only used it once and wasn't convinced it helped in my case. If you've got data taken over several hours you could always separately process those files an make an animation showing the rotation of the planet? There's a good video that someone recently posted (apologies i can't remember who) by Damian Peach about how he goes about planetary astrophotography which does include a bit about processing which is definitely worth a look. There should be a few things on youtube about pipp too if you want more detail on that.
  9. That's a good image. There's certainly some nice surface detail there; you can definitely be pleased with that. Can you combine your files in pipp before running through AS3? That would give you an avi file with more good frames. You might try stacking more than 10% too. Worth experimenting as I sometimes find more can improve things. I often try 20 or 30%. I haven't seen mars for weeks it seems with the constant cloud, so its good to see.
  10. For me, binoviewers do greatly improve my viewing experience when it comes to the moon and planets and on the moon it is more immersive. I find it much more relaxing to have both eyes open than it is using one, and either covering the other to keep out stray light or closing it. I think this is key to why they appear to show more detail. Anything you can do to make your viewing more comfortable allows you to concentrate on what you're looking at. They don't suit everyone though, and you do have to tweak them a bit to get both eyes right, but this isn't difficult. I think the reason for the low power eyepieces is that the corrector fitted to the binoviewers acts to magnify the image, so with the william optics ones I use, the supplied 20mm eyepieces act more like 10mm. The image you get is less bright than a single ocular though, so for me they are a much poorer thing to use on deep sky stuff. They also add weight to the setup and alter the balance point and I've heard that some scopes don't always have enough focus travel for them to reach focus, although all mine do. Best to try before you buy if you can.
  11. If its planetary imaging you should be ok. My exos2 copes ok for visual but it looks a bit undersized for the scope. Not tried imaging yet but think the heq5 can take a couple more kg than mine.
  12. I've had my 8cc out a couple of times now. The first was a pretty damp night with lots of dew on the outside of the tube after around an hour or two and the finder was completely dewed over, but there was nothing on the mirrors. I'm guessing dew straps would be a good addition if you're planning a long session in this climate though.
  13. Gorgeous looking scope. like others, keen to know how it goes.
  14. That's what I did and it looks much better. Amazed how sensitive the secondary screws are, so only tweaked them slightly each time. just need some clear sky now!
  15. Sorry to hear that. Mine was out too, with both mirrors needing a good tweak, presumably from transit.
