  1. Maybe I didn't ask the best initial question! Perhaps I should've asked what is the best software combo alongside PHD2 to enable me to capture images using dithering between exposures.
  2. Yes I could do, but not sure that this can handle dithering linked to PHD2 ?
  3. Yes I have a 12v powered Startech hub, but struggles with USB3 over the 6m cable length I have. I use a Lindy active cable
  4. Thanks Steve. Yes, I've tried connecting my cam (various ZWO) using USB3 cable through a powered USB hub, but I often lose the connection - probably due to cable length being >3m. I've tried an active USB cable connecting the hub to the laptop but with little success. Not sure how to resolve this, other than to plug the cam direct into the laptop. My aim is to to have my laptop in my warm room, rather than next to the scope, but this requires longer cable runs. Any ideas to improve this would be very welcome! Thanks
  5. I currently use SharpCap for planetary / lunar SER video capture, which I am fairly familiar with. I now want to take the dive into DSO image capture using CMOS cameras (up to now I've used simple DSLR imaging for DSO). I use EQMOD to link my planetarium software, CdC, to my EQ6 mount, and use PHD2 guiding with a guidecam plugged directly into the laptop. My question is how APT connects into this system. I want to use dithering between image captures. So the stupid questions..... I presume that APT completely replaces SharpCap for image capture. Is this right? For dit
  6. Thanks. Yes, I've got the 8mm adapter. I'd considered using this but I've not seen the extension tubes you mention. I'll have a browse to see if I can find any that add up to 55mm with the required M48 and M42 female fittings. Have you seen these?
  7. Hi I use the dedicated field flattener for my Esprit 100. The back focus distance to the sensor of my ASI294 must be 63mm. The sensor itself is 6.5mm from the front of the camera body, so I need an adapter of 56.5mm. Is there anyone in SGL land that has this combo and can advise on a suitable adapter or adapters for this combo, or suggest an alternative method of attaching the camera? I won't be using a filter wheel. I can't find a single adapter of this size, not surprisingly, so am probably looking at multiple rings to make up this distance. The fittings need to M66 femal
  8. Thanks. Yeah I'm keen to have a proper go at a longer animation sequence, but haven't had a decent night since I took this one!
  9. Yes, I have WinJupos, but have not looked at it yet! I hear it's a great program though
  10. This short animation is made up of 5 images taken on 22nd Sep at approx. 15 minute intervals, spanning 1 hour. Equipment - Celestron C11 working at f/20, and ZWO ASI174MM. It would be interesting and fun to try and go for a longer duration if the clouds and seeing play nicely
  11. No, this was just a single exposure with a mono camera without filtration.
  12. Thanks . This is lifted from the BAA website I think. A really useful tool, but many finer features are not labelled. Still really good though
  13. Thanks I'll take a look . EDIT - ah yes, this is the BAA site map. I use this already, and it's excellent at showing the features at any particular time. I do think that the labelling is rather poor though. Not always clear which bit the over-laid label is referring to, and there are many feature names that some people refer to in their posts that are not labelled on this map. Still really useful though
  14. Thanks. Learning curve - tell me about it! I still haven't cracked how to get it in sharp focus. I tend to take loads of videos, refocussing each time, process the lot and choose the best 2 or 3. Nights of good seeing are obviously easier. This wasn't one of those!
