  1. Welcome, from another Cambridgeshire resident!
  2. yeah, I'm happy with the 3B+ but there is always something better. Programming it (following instructions that is) right now!
  3. Its the confusion on the advert and my inexperience with RPi which caused my error. Got a 3B+ on its way as we speak. Just wanted to offer it to anyone on here before returning to Amazon. David
  4. Ordered the wrong Raspberry Pi for my All Sky Camera Build and so it is for sale. It is this one: https://www.amazon.co.uk/gp/product/B00LPESRUK/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1. I have taken it out of the static bag just once but put straight back in when realised it wasn't the one I wanted. £20 +P&P
  5. Both Starnet and Annies Actions are very good; Starnet to remove stars so the you can stretch an image without blowing them out, and Annies actions to reduce them. Starnet is free and standalone, and Annies Actions for PS. Both are an integral part of my processing. Davis
  6. Agreed. Pretty sure that darks are applied to each individual frame in APP rather than on the final stacked image meaning that both are valuable in the overall image. Going through the APP work flow, Calibration is the step before any stacking is carried out allowing you to check effectiveness of the calibration frames; darks, flats etc, before Normalisation and Integration. You can select this at the top of the graphic display for each individual frame in APP. Hope this helps. David
  7. Thank you. Its the first time I'd done NB and whilst its quite straight forward to get the basic colours following all the advice on here and other places, the time consuming part is fine tuning them to taste, and a calibrated monitor helps too plus clean glasses!
  8. Thanks Steve. They were generous in providing a few hours here or there, if I'd been good which cant have been that often.
  9. I had this problem and went around the gap between the mirror and tube with black insulation tape. Latest solution was that I made a foam cap to slot over the end. I also tried a good quality black bin bag. Never thought of a.......... Was only a problem if I was taking darks or flats during the day. Easy to solve but guess its more annoying than anything.
  10. Thanks guys. Nice to know that I'm on the right track so far.
  11. Following on from my previous post, another hard fought battle to get enough subs to make an effort producing something this year. Anyway, my attempt at the Tadpole Nebula. Found this one a challenge to process and kept starting again. Couldn't decide on the best way to process the stars; processed starless stacks and tried reintroducing then through a Ha Luminance layer or adding a star layer but wasn't happy with either so settled upon leaving them in and masking them whilst doing the stretch. Forgot to say on the last post, stacked and pre-processed in APP and processed in PS CS5. Details: Ha - 82 x 3 min Sii - 62 x 3 min Oiii - 38 x 3 min Total - 9 hrs 6 mins Gain 300 Offset 20 Thanks for looking. David
  12. My first posted picture for quite a while. Been battling gremlins that resulted in stripping down my mount and regreasing etc, all to reduce the amount of lost subs due to being overweight - the scope that is, not me though I could do with shifting a little. Unfortunately do not have the luxury with reducing the scope weight - almost 13kg on the HEQ5 Pro but got the rejections down to about 10% rather than 50. Like the rest of us UK based fools, battling the clouds for some time too. Anyway, woes aside, here's my attempt at the Monkey Head Nebula. Equipment below. Details: Ha - 90 x 3 min Sii - 68 x 3 min Oiii - 75 x 3 min Total - 11 hrs 39 mins Gain 300 Offset 20 Constructive criticism more than welcome. Thanks for looking. David
  13. There are a few simple gotchas with the polar scope and I'm ashamed to say, both have caught me out!!!!!!! 1. Have you removed the black cap from the opposite side of the mount? 2. Is the Dec axis in the correct position. There is a hole in the Dec axis spindle/axle that is aligned with the polar scope. A symptom of either of the above, as well as not seeing any stars, is that the the polar scope illumination will appear too bright. Hope this helps but both can easily catch you out. David
