  1. Will do. A little way to go yet to get the new observatory weather proof
  2. The powerpole distribution boards and connectors are cheaper than the neutricks and the distribution boards are compact and already made up. No sockets to mount and wire. The plugs are also crimp connections so no soldering. I am about to wire up my rig using them, so I will find out how easy it is in practice.
  3. That is pretty damned impressive!
  4. Roof completely clad and flashings added Protective plastic is still on the flashings as it was about to chuick it down with rain . Not sure I can be bothered to remove it . Next step the South flap, at which point it should be weatherproof enough to lay the floor in the scope room and start installing equipment .
  5. A good days work yesterday on a blustery but dry day. Finished protecting the roof frame and got it up on the rails. It moves! It lives! It breathes! And started work on cladding the rolling roof. I hope to finish off the cladding in the next couple of days and permanently fix down the rails.
  6. Roof shingles certainly look nice, but I found no problem with an EDPM roof for my warm room. Installation was easy after watching the required youtube videos, and fast. One of the quicker and easier jobs for me in my build.
  7. Roof frame delivered. Now in the process of cleaning and protecting it. You can see the wheels and the gate opener rack that will be used to open and close. A slightly odd view as it is standing on end while I spray it with cold galvanising spray as recommended by the man who made the frame. Now I have run out of spray and the builders merchant who stock it don't open again until Monday. Curses!
  8. Very useful. I have been thinking about Voyager for my new observatory. Never had a need for that level of automation before, but interested to try. I like the approach of Voyager and your videos have helped me understand it. Thanks
  9. If you have only used Paint to make adjustments, then there is a lot more opportunity in Photoshop. Clever things like using the high pass filter on a copy of the image and then blending it into the original using the overlay mode. This can make your nebula images much, much better. In Photoshop it is fairly intuitive, and you just adjust sliders to change how much of each layer you want. Sounds complicated, but it is easy to do because you can see exactly what is happening. I am sure it is possible to do the same thing in PI, but I have not achieved the same effect (no doubt a PI guru will rock and give us the exact recipe). probably the best thing to do is look at some online tutorials using PS and see if the make sense to you and if they look like they fit the way you think about what you are trying to do.
  10. The user interaction model is very differnt for PI and PS. In my limited experience PI thinks about data and what you do with it. There are tools that give you previews so that you can see what effect you are having, but fundamentally it feels like an image processing package. Algorithms and mathematics to the fore. PS is more image driven and takes its metaphors from photography and painting. You do things that you don't necessarily have to understand while watching the effect on the image directly. That means it is more immediate, possibly more intuitive, but less clear what is happening. Two different styles of thinking. Many people use both. A good example of a master craftsman (at least compared to me) is @ollypenrice. He uses PI to do all the basic processing to get the integrated and merged image. Then he moves to PS to enhance using multiple layers and masks, touching up and blending to get the effect he is looking for. A more artistic and less scripted process. I think personal preference comes into it a great deal. Ask yourself whether you think about applying known algorithms to enhance your image in various ways, taking a step by step approach with total control, or do you favour working directly with the image and 'painting' your way to the goal? Both deliver outstanding results, but different strokes...
  11. A very pleasant couple of hours just sweeping around looking at favourite targets. Lots of mist and thin cloud creating major light domes from nearby towns, so only the easy stuff. First view of the Pleiades and M31 this season! Always nice to remake their acquaintance.
  12. Yep! Going to heave the Dob out into the drive in a minute.
  13. Article from New Scientist https://www.newscientist.com/article/2218628-andromeda-galaxy-ate-several-dwarf-galaxies-in-two-course-lunch/ analysis of globular clusters left over from galaxies absorbed by M31 shows two distinct populations. One with a lot of retained structure from the original galaxy and orbiting one way around M31 - indicating a more recent interaction - the other with less retained structure orbiting the other way round - evidence of a separate earlier event.
  14. Thank you. I hope I can turn the promise into performance. I am not a natural completer-finisher, so this is all difficult stuff!
  15. So, there has been some progress over the last couple of weeks. Now in a mad rush to get things at least operational before we lose the light and definitively move into the Winter observing season. Unfortunately not everything in my control. The warm room has been completed, insulated and lined. Power and data in, and a shelf/desk constructed out of the leftover OSB from the warm room roof, strengthened with some leftover battens. The strange blank panel on the right is a result of a late decision to power/automate the roof using a gate motor. That gap is where the gate motor will go in some yet to be determined fashion. There are narrow double doors from the warm room to the scope room. After playing around with a sliding door, this seemed to be simpler. Also a window to check what is happening out there. Doors have no fastening mechanism at the moment so being held shut against the wind with a paving slab. There is a main door into the warm room. And a view of the scope room and warm room wall. The tarp is because the warm room wall has not been constructed to be directly exposed to the torrential rain we have been having, so a little protection until the roof is in place. I have been to see the roof frame at my neighbour's and it is nearly complete. He might bring it up tomorrow. Then it needs painting/protecting with a cold galvanising spray, aligning and fixing the rails so it runs smoothly and then adding the cladding. After that I can install the scope room floor and start to set up the equipment. Lots of bits and pieces to do like corner flashings, end flap, rainproofing, painting warm room etc, but at least I will be able to turn part of my attention to whether the new mount/pier/scope combination works OK. Longer than I thought (inevitably!), but the end is in sight unless I discover a new "oh [removed word]!".
