  1. David All this detail is amazing and guess I know how I'm doing my roof now. I particularly like the Benny Hill music on the second video. That show is a fond memory from my youth, probably never to be repeated! I was going to ask how the roof stays on but guess that is the pivoting arms that do that! What is the roofing material? David
  2. David What size is your observatory? I need to downsize mine and now seems a good time as the roof needs replacing. Yours seems perfect, especially how the roof opens!! Thanks to Gary for reinvigorating this thread and highlighting your set-up! Kind regards David
  3. I was recently allowed to purchase the excellently reviewed RVO Horizon 72 ED and field flattener but am struggling with the spacing/backfocus between flattener and sensor (1600mm). Its meant to be 55mm but test shots showed the sensor to be too close. I've increased the spacing to 60mm with the same results. Seems odd that I've increased it so much so doubting what I've done. Has anyone else here had experience with this particular combination or can offer advice? Attached is a shot from the other night showing my problem in the corners; trails all pointing to the centre. Please for
  4. You are quite right. My bad. I hadn't noticed the closing date so judges please ignore my entry. David
  5. Excellent data, yet again. Thank you. Here is my attempt in SHO palette and processed completely in PS CS5. Initial stretch of each channel with levels and slight curves. Removed stars from each using Starnet++. More stretching of each channel using levels and curves. Removal of some of the larger artifacts in each cannel using Spot Heal Brush. Brightness & contrast. Local contrast enhancement (Astronomy Tools plug-in). Tweak of levels. Combined each channel in PS. Selective colour, hue, saturation and vibrance adjustments.
  6. Welcome, from another Cambridgeshire resident!
  7. yeah, I'm happy with the 3B+ but there is always something better. Programming it (following instructions that is) right now!
  8. 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
  9. 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
  10. 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
  11. 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
  12. 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!
  13. Thanks Steve. They were generous in providing a few hours here or there, if I'd been good which cant have been that often.
  14. 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.
  15. Thanks guys. Nice to know that I'm on the right track so far.
  16. 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. Deta
  17. 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 -
  18. 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
  19. I wonder if it is the same as in DSS. Select it as the reference frame but leave the checkbox in the file list unchecked? David
  20. Yes there is. I'm at work at the mo so not too sure but either on the Register tab or Integrate tab there is a large button labelled 'Set Reference Frame'. If you are stacking frames that are binned with those not binned, ie when processing LRGB for example, you need to ensure that an unbinned frame is selected so that APP knows to resize the frames that are binned. Hope this helps but sure someone can supply the facts shortly. David
  21. I had a similar problem and found light was entering from around the primary. Quickly cured by covering the mirror end with a few thick bin bags. Didn't notice at night because no ambient light!!! David
  22. That's excellent! I have the same 'scope and camera combo. What were your gain and offset settings? David
  23. New camera, new pc, flocked tube, belt mod and new auto focuser and not enough clear skies, hence why probably rushed last night. At least did all those upgrades over the extensive cloudy period! Think next task is to get auto focuser sorted and then guiding.
