  1. WOW for a first attempt well done! Really nice, bet you have some amazing skies as well
  2. Thanks Ian, good to hear what others do. Not had a clear night ina couple of weeks to try it out again though!
  3. Amazing - was wanting to try this myself with my daughter who just started studying Astrophysics. Will see if we can replicate what you have done

    Yep I did the same, although if the mount is brand new I would not be expecting to do this myself so I would send it back for replacement

    A couple of firsts for me: NGC6888

    I have been using 5min subs at max gain when doing narrowband - not sure if i should shorten them but how can i tell? great image though!
  6. Here is just the Ha uncropped (had rotated the camera for the O3 so its cropped)
  7. I had a problem with the O3 when i took it - was out of focus so its not going to win any awards!
  8. How does this look for my first narrowband

    I have to say I have never really noticed any issue with the smaller images and if I want to see the high quality version I know I can click the picture to bring that up. I do think its going to make browsing on a mobile device a lot harder, although maybe you can have different settings for the mobile version of the site?
  10. Im new to narrowband imaging and have a few questions around the way the narrowband images are converted to colour - I know there are no rules and ultimately it is down to the individual how they combine and present but I just wondered about some general 'rules of thumb' to guide me in this new aspect of imaging! So.... Do you always try and get all three narrowband images, so Ha, O3, SII and then resort to creating a false channel when you dont have time etc or are there reasons/targets that Ha only or Ha & O3 work best? I suppose I mean are there targets that gathering one of the channels is not worth it as there is no data? If you are generating a missing channel, is it a mix of the other 2 or can/do you use one of the channels twice? What colour do you assign to each channel and again, in general, do you always go with the same combination, or again does this depend on target? Do you go for the same exposures? I found the other night that I had to double my O3 when on the Heart Nebula (which has been my only target so far), and again what about number of subs, do you try and get the same for each channel? Are there any gotchas to watch out for when imaging and combining narrowband into RGB? My last camera was a OSC QHY8 so this is all new, but so far Im enjoying the new challenge
  11. I’m building an auto focuse for my zs70 so that I can refocus between filter moves
  12. Well I got out last night and did as had been suggested, stand the scope in its end and add the bits back on so gravity is assisting. This worked a lot better and seems to be back to normal, still seems I need to add more spacers between the flattened and the scope but I will order some of those spacers from flo, at the moment though it’s an issue of elongated stars as I originally had and the out of focus ones are gone!
  13. Tonight looks to be partly clear, will do a has been suggested and try again - wish me luck!
  14. Thing is the left hand image is before adding more spacers and focus in the centre was bang on both times as I used a focusing mask. So it looks like the before image was in better focus than the after image but the before image was closer to the FF which does not make much sense to me.
