  1. Any guiding results? Just to see vs the iOptron encoders. Would you be able to grab a unguided log for the worm period with fast frame rate like 1 second exposures using subframe mode? Just to see what the true native PE is and if there's any issue with the encoder implementation. Your setup looks quite massive. Must be a lot of work settings up and taking down!
  2. Finally. https://www.astrobin.com/ci0vg7/G/
  3. 2 more frames left.
  4. Working my way over.
  5. One frame at a time... frame two. Of course after last night clear, tonight forecast clear but turns out overcast. https://astrob.in/ci0vg7/D/

    The single sub is still noiser.
  7. Yeah I know, it will have the whole lot when it's done. When you have something so big what do you call it is sometimes unclear to me anyhow. Can't call it Bob LOL.
  8. Yep I'll try for 6 and see if I get enough nights to do it. 10 inch scope is not something I like to put on and take off every few nights so mosaics allows me to keep it on. And it is fun to get a larger picture.
  9. https://astrob.in/full/ci0vg7/0/ First of 6 frames. Hopefully whole image will turn out quite well.
  10. Don't have a Ha filter this is an OSC image. Thinking about getting the tri-band type filter maybe, or a mono setup.
  11. Saturating was the way to get the faint details to separate from the background. I already masked the stars but it still seems to have an impact. More data might help in that regards. I am debating if I should go out tonight with the nearly full moon or if it would be a bust trying to get more data on something faint with the moon blazing. Thoughts?
  12. https://www.astrobin.com/wghzkc/D/?nc=user Had some trouble before with the faint bit, but some more effort and sub seems to bring a bit of it out. Maybe add more hours?
  13. The rainbow one however, especially the smallest one seem to have quite bad PE. So I'd becareful and hopefully buy with a good return policy.
  14. Not going to suggest you get an iOptron because support in the end for me wasn't so great but maybe different in Europe. However, I am running right about 22 kg at 1000mm and 0.7" scale on a cem60ec. It seems to work fine and my images are dominated by my collimation or optics issues. I don't know if you need encoders for an RASA thought. It's not going to be a small image scale system is it?
  15. The one example of the RH was not impressive. Maybe needs more adjustment but at the asking price you have other options. Encoders are not needed for even long lengths if PEC works or native PE is low. It's a nice idea if it works.
