  1. Hi John, welcome to SGL. I have visited La Palma on several occasions and I really love the place. I remember well my early disappointment at the cloudy late evening sky at Puntagorda on my first visit and how I woke up half way through the night and ventured out to see if it had cleared. Looking up, I noticed a long tendrilous cloud overhead and was about to go back inside disappointed once more only to realise that this was the most breathtaking swathe of the Milky Way that I had ever seen! A visit to La Palma is never complete without a visit to the Roque de Los Muchachos and the amazing feeling of clean, thin air above the clouds is intoxicating.
  2. Lovely images, Olly, the close-up in particular - very, very nicely done.
  3. There are plenty of great resources out there but here is a good starting point that doesn't assume any prior knowledge.
  4. Wouter, that was a really wonderful start to my day - a beautiful presentation with some stunning images - thank you for sharing!
  5. You need to run either the Straton or StarNet++ processes twice with different settings so that you end up with a second image containing just the stars. If you are using PhotoShop, to add the stars back in again after you have processed the starless nebula, copy the stars onto the nebula as a separate layer and then change the blend mode to 'Screen'. This can be a very effective way of processing as it gives you extra 'headroom' for stretching the nebulosity. However, there are also strategies for producing star masks to protect the stars in both PhotoShop and PixInsight.
  6. Very nice indeed, John and so lovely and close in! Good luck with the op.
  7. It's not the domes per se, it is the fact that they have thin uninsulated glass fibre skins. I run a desiccant de-humidifier in mine to completely alleviate the problem.
  8. Wow, that's a cracker - so much lovely dust! Beautifully done.
  9. I use both PS and PI and like both of them. The two programs work very differently from one another but both have their strengths. For years I have used MaxIm DL for calibration, registration and integration and have found it to be fantastic but in the last year or so I have moved these tasks over to PI as I prefer the results it achieves although it is not a straightforward to use as MaxIm DL which is, in my experience so far, typical of many facets of PI !! I also use PI for deconvolution as it is the only software I have ever used that actually seems to work consistently on this important task. However, as soon as I have my integrated and deconvolved master image I happily move on to PS for the rest of the processing. Why? PS works almost entirely in real-time which means that I can readily see the minute changes that I make immediately, as I make them - something that PI cannot match. I also love the 'layer' features in PS as they are so intuitive to use and again, you can see everything that is going on. PI will do all that PS can do and more but it is not to my mind as intuitive to use and that is the rub for me. However, I can see that because of its immense power, aimed at our specific requirements, PI is a force to be reckoned with and is worth persevering with UNLESS, like me, you already have an investment in both time and money in PS. For me, I use the best features of both programs.
  10. Well it looks in great condition and that explains the modification to the skirt on the dome section - I guess this is an additional drip rail?
  11. Great news - you are in for a treat! A couple of pointers:- 1. Concentrate on getting the base of the dome and the top of the walls flat where each section butts up to the next as this will ensure smooth rotation. 2. Don't rely purely on the pre-drilled holes - file any out that impede 1. above - To be fair, my bolt holes were very well aligned straight from the factory 3. Spend plenty of time ensuring that the north-south diameter matches perfectly the east-west diameter on the walls before you bolt it down to the plinth.
  12. Thanks for your comments, Adam. Thanks, Mick.
  13. Thank you Rudd, I'm pleased you like it Thank you Richard, colour is such a variable thing. I like subdued colours as they make deep sky images look more 'dusty' which I guess is why I settled for my first rendition but the more saturated version also brings out some added depth! It is not unusual for me to do several orisons and in fact, my original is in fact two versions combined ....... Thanks, Martyn much appreciated.
  14. I have my dehumidifier running all the time that I am not actually imaging and it has kept my gear in perfect condition for years.
