  1. That’s quite scary for a beginner in a light polluted area. I guess we just have to deal with cards we are dealt and be prepared to drive to a darker site.
  2. Just re read your original post. Don’t put your scope out so early. It is important to get your scope equal to outside temp, but if it is running in water then not so. I have the same problem. Scope out to cool down, half hour later ringing wet and no viewing. A lot of it is not our fault. My last clear sky was Oct 9th, then rain for ever. First clear night after forty nights of rain is going to be saturated. Just because I can the see the stars tonight does not mean ideal viewing conditions. The other thing is, put your scope out to cool down but put a light weight rain coat over it, why give the dew a head start. Marvin
  3. There are many well educated people on here that will direct you to specific anti dew systems which you are going to need. Plus the power system to feed them. Dew is a bane of of our lives. You say after three hours, you lucky duck. I have tried wide field photography destroyed by dew after fifteen minutes. I guess it depended where you are. There are dew bands that Velcro around your scope and accessories that run on battery packs. Check out FLO under dew control as it starts simple and can get very complicated depending on the amount of external areas you wish to keep free of dew. If you are visual only then it is not a big deal. For visual I have a small hair dryer on an extension lead from the house, does the job fine. Marv
  4. For fear of anyone on this thread thinking I am picking a fight, or dising anyone’s efforts in Astro photography, I can clearly say I am not. I am quite new to all this Astro stuff but not new to photography. I came up in the 35mm film era which is a pain as I became that age group that embraced computers or got left behind and I am in the second group. By the way I bought the bought the book. ‘Thank you Steve’ and I was most surprised by your personal reply to me, which I did not expect. The ‘thing’ that is bothering me reading this thread is the utter reliance on software and computer compatibility. Now I realise that if you want a remote obs then computers have to be running things. Here come the tough bit... How many clear nights have been wasted trying to get systems to ‘integrate’, domes to aligned, mounts to track, etc. I am at present a visual observer with small kit, and I have had diddly since October 9th without missing an opportunity. Frankly with this amount of opportunity, adding all that infrastructure seems restrictive as I would have no images to process. I can see what you are all trying to achieve and it is a thing of wonder. But with modern weather and system errors and incompatibility I am wondering if it is something along the lines of the law of diminishing returns. I see so many posts with software issue this, problem using version that, I wonder where the astronomer ends and the IT tech begins. All this from a guy that wants to do astrophotography sometime in the future. Marv
  5. I was certainly taken aback by how aggressive he is reported to have been. I know there are rules on here for keeping it clean and I have seen some comments about swear words in inverted commas with the central letters missing, to leave it to our imaginations not being acceptable. However, this is the work product of Sir Patrick Moore, Brian May, and Chris Lintott I am going to quote. (Despite copyright law as I am going to also say buy this amazing book, perhaps their legal team won’t kill me) ”He references to his colleagues as “Spherical B’st...s” Spherical, because they appeared to be “B’st...s” no matter which direction you looked at them from. According to this record he threatened the life of Walter Baade who was a colleague at the same university simply for being German at the time of WW2. What an unusual guy. Clearly exceptional in his field but I am unclear as to how to feel about him as a fellow member of the human race. Marv
  6. That’s the stuff, you have the beginnings of your own Astro society. M
  7. I reply to all of the above as the questions are valid. I live in a very rural environment. I have one neighbour who is lights out by mid afternoon, different story. Nearest village is three k away to my north west and the street lights go out at midnight. My Southern horizon is somewhat compromised by three large towns and a nuclear power station 25k away, which do not effect visual normally, but show up in photography. My North and East are totally uncompromised and the air quality here is superb, especially as the rain has been cleaning the sky for over a month. The Pyrenees mountain range is 100 k away and after rain I can see snow on it’s slopes. The thing that really got me is the uniform ‘unseeing’. We all get used to something getting in the way, ‘but the whole sky’. I can only think it was a high level super thin over cast, uniform across the whole sky reflecting light. Marv
  8. Hi Draven There is a current thread in Communities about the Bristol Astro society. They will have the stuff you need. Marv
  9. Nice one, you got some crisp detail for day time. I am going to get my lunar map and check out the southern lunar crater area. Please try this shot night time if your weather allows, my best ep shot is still my screen saver. Marvin
  10. Thousand kilometres south and full cloud here and back to rain by the morning for a long period. Farmers plowing the fields through the night with flood lights attached, never a good sign. If it wasn’t for the cloud I would complain about the mobile light pollution. last proper clear night October 9th!
  11. I will get a copy of this, as I was just this morning reading the fascinating book BANG the complete history of the universe, by Brian May, Patric Moore (no Sir) and Chris Lintott. In the back pages are short biographies of the most important and Zwicky certainly stood out. His picture is highly animated and I thought about posting it here but I am aware there is something called copyright law. Marv
  12. I don’t know if you get like this, but I thought I would try to interest non astronomers to our past time by talking to a few friends. I managed to persuade my friend John that this was going to be epic. He has never started gazed, but has an open mind. 4:30am he text me to say he was up dressed and ready to go outside at his location 25k away, I am impressed. He says he is in thick fog so I am expecting the next text to say he going back to the warm inviting embrace of the duvet, but no... John is going to walk a kilometre out of the village in the dark, three deg above freezing to get away from street lights to the water tower on high ground above the fog!!! He gets there to find that the Orion portion of the sky is clouded out. He didn’t even moan about it, I have had no abuse. Perhaps he should be the next astronomer royal, John you are a gem. Marv
  13. I had the camera running as well and as far as I can tell I got zip. I have to down load them and look on a decent screen. Hopefully next time it will be the big one.
  14. I did go back over the original report on Sky and Telescope I believe and they do say debris field is very small I guess earth just skimmed it, not ran right through it. As for getting out I am motivated, I have not seen a thing due to weather since October 9th.
  15. I put a heads up on this site about this one as it was going to special..... I feel like I persuaded people to get of bed at dark o’clock in the morning for next to nothing. I was up and out 4:30, set up the camera, text a few friends to gauge interest. For the first time in over a month I have a clear sky, can’t believe it. shower peak 5:50 my time and I saw a grand total of six meteors! The expected zhr was 400, what happened? Did anyone else get a better show? Marvin
  16. I have now returned to the warmth of the house after seeing the shower. I will post in observing. Marvin
  17. First night out since October 9th, weather has been terrible with the exception of three clear nights bang on the full moon! So didn’t bother. 20th November, 20:00hrs no clouds, no rain, no fog or all at the same time which has become normal. It’s dark, I can see constellations, and a light milky way. After observing for thirty minutes I am finding it more difficult not less. I have no moon at present and the sun set two hours ago. I know it is far from ideal time but I work, so going out at 2am is reserved for days off. I step away from the scope and just take stock. The whole of the sky from horizon to horizon and to the zenith has an equal opaqueness. Like a reduced full moon effect, but with total uniformity. I can look at stars and can see Andromeda and a few open clusters in Cassiopeia. I can only guess the cause is a full thin high overcast reflecting light pollution. My issue is I have no light pollution to the north of my position but the sky was equal all round. Anyone else had this phenomenon? Marvin
  18. Just seems odd posting an account of not being able to see anything on Observing, but I will give it a go. M
  19. Wired thing it is uniform across the whole sky from horizon to horizon. Any indicators as to where I should post this as a topic, I am thinking observing? M
  20. Just come in from an hour or so of observing. Feel really bad moaning as my last opportunity other than three clear nights dead on the full moon was October 9th. No observable cloud. Constellations clearly visible, little if no star twinkle, some milky way visible, great. It’s early evening so ideal middle of the night conditions but I am a working man so that’s how it is. Some open clusters in Cassiopeia but trouble finding focus, nothing is really clear. I stand away from the scope and just look around. There appears to be a sky glow, like a uniform light source across the whole of the sky, like a toned down version of a full moon. I have no moon at 8pm where I am. I can only conclude that a high ultra thin overcast has come over and is reflecting distant light pollution that is not normally an issue. Anyone else have this problem? Did think this should be posted in observing but I really didn’t see anything. Marv
  21. Seb-B John that just posted on this thread is someone you should follow. He is one of the people on here is mainly visual based and nothing but sense comes from his posts. Another is Stu. Marv
  22. Rudd is spot on. Stellarium is free and a great portable planetarium software which I use.
