  1. Great image - I find deconvolution difficult and often end up with 20 images which I have to go back to a few days later to choose the one that's both showing more detail and aesthetically the most pleasing(they are certainly not the same thing).- Tony.
  2. I had a spider in my pipe! Have you checked the pipe carefully for residents - evicting the spider cured my problem which was the same as yours- Tony.
  3. Hi - love the dense star fields but as you say you are blue to the right and red to the left so I would look at gradients in the red and blue RGB data to correct - best wishes Tony
  4. Great images Steve! I am beginning to wonder if H alpha monochrome is the way to go as so many of my opportunities are the odd night or moon limited and for colour images with a good amount of luminance I need at least 3 good nights- always think monochrome is beautiful in its own way -great result - Tony.
  5. Great image even without the Supernova!- I love those distant barred spirals!- Tony.
  6. Great wide field !- I love seeing these really distant guys and there are so many here!- Often they just crop up next to your primary image target which is always so compelling in terms of impressing on us the enormity of what we image - Tony.
  7. Hi Nigella - a windscreen motor is the right way to go with a 12v dc power supply -with the older style dome a 12v battery and motor attached via a shelf on the roof is the simplest way to go . The motor engages with a belt attached to the wall of the dome via a gear that can all be obtained from motionco an on line retailer -can pm you pictures of my setup if you want . I have gone on to use the Vellerman board and Lesvedome software to slave the dome rotation to the scope which is a great help. Best wishes - Tony
  8. I think unless you are planning to use an encoder that's fine but for slaving your dome with an encoder slow is best and leads to less mistakes and inaccuracy - mine slews about 90 seconds for a whole rotation but slaves well - Tony
  9. Hi great info - rubbish weather in the south too - fancy your NGC 90 suggestion-only got one luminance the other night before the familiar cloud and rain! -thanks Tony.
  10. Great image and fine dust lane /galaxy detail - Tony.
  11. Great !- I've just talen 8x20 minute Lum subs for this and been frustrated with bad weather and the moon so no colour- must process anyway - a great target ! - best wishes Tony.
  12. Thanks Steve -very useful - my Decon in Pixinsight has given very variable results-Tony.
  13. Yes -reducing ticks per revolution should speed up the mount - Tony
  14. Hi - I experimented with RA ticks per revolution with my Mesu as even when polar alignment was perfect it did not track at a completely reasonable sidereal rate - after finding the fine tuning spot for RA ticks per revolution guiding was much better and RA corrections much less with a flatter PHD graph-you can measure RA drift and then work out fair corrections- not sure if this is useful but certainly had to work on this a little and had good results- Tony
  15. Hi - I used the 8 ppr Bourns encoder with LesveDome and a windscreen wiper motor and my old style 2.2 Dome will track an object I am imaging pretty well which is all I wanted - the problem was not attaching a sprocket but building the dome drive system that took many prototypes as I like to call them {failed ideas others might say ) but you seem to have done this so the rest should be relatively easy - Tony.
