  1. I have to ask, your avatar? Looks like a complete gem.
  2. Definitely not an expert in this field but I got a great look between storms this evening. Big hole in the sky from horizon to horizon but this will last one hour before the weather front rolls in. Orion, the entire sky, constellation Orion, Taurus, and the surrounding constellations. Betelgeuse is sooooo dim. By naked eye, I would say one magnitude less than Rigel. Has this been the case at anytime in the viewable past? Please bear in mind I am just one of you, so my idea of magnitude maybe less than scientific. On the other hand if a PHD wants a fist fight I am more than willing to apologise. Marvin
  3. The most important thing in all of this, are you ok? I hear laser eye surgery and it gives me the chills. I do hope all is well. Marv
  4. Dude, that really is a thing of beauty. No idea anything like that existed. M
  5. So happy to have you here. The enthusiasm and warmth for the subject are obvious and contagious. Your line in your post that something so simple could be so amazing sums up how a lot of us feel. I hope you enjoy this incredible journey. For me personally it was like having the top of my head removed, quick play with the grey matter, top of head replaced and I came out the other end a different person. I sincerely hope that you continue this amazing journey and encourage the younger generation to do the same. I hope your five year old daughter is in as much awe as me, and you, and hopefully thousands more.
  6. Wednesday was blue skies and for once it did not cloud up by five pm. Decided to put the Nikon on my 150pds and have a go at taking my first DSO picture. M31 is a single image of 180 seconds at ISO 800. I sent it to Bukko for critical examination and he very kindly asked his son to see if it could be tweaked a bit. A little bit more detail of the dust lanes became apparent. Next opportunity I will try to grab a whole bunch of these and try a stack for the first time. Marvin
  7. Fed up with everything getting soaking wet. Just received a Lynx Astro dual port dew controller and Astro zap heater band for my 150 pds. Tested it yesterday and Against all odds the skies were clear and the atmosphere was bone dry!!! Is that the equivalent of equipment anti matter? Marv
  8. Wow that sure is an in-depth answer. I would give you sixty seconds under interrogation. I will look up IC 443 and see where it resides in the sky. Good luck capturing that S11 data, I hope you get to post a complete image that you are happy with soon. Marv
  9. I am unfamiliar with IC443, any further details would be much appreciated. Looks like you captured some amazing structure. What equipment are using? Marv
  10. Nice one John thanks for the link. Very reasonable prices too. Definitely something I will get into in the future. Thats me with my hand on a very expensive nickel iron lump at Greenwich between Christmas and new year. Older than planet Earth apparently.
  11. If I have clear skies tonight I am going to get right on this. I find meteorites fascinating. To be holding something that was once flying around in space is incredible. I have always had a dream of owning a decent size nickel iron meteorite with thumb printing. I know they can be bought on the web but I have so much more astronomy kit to get so it will just have to wait. Marv
  12. Dumbo, something feels wrong about that. What an impressive first step into the heavens. Good size dob, and the smaller grab and go, although to the coffee table. I am impressed by your pictures, most people see high end images, fully processed and shy away from posting there efforts, I always think there is not enough posts from new members. Well done you for giving it a go and getting some results. Keep a diary, record everything you see no matter how 'matter of fact'. Quote "Your journey into this amazing night, will last a life time if you continue to wonder and it will be a most fulfilling pursuit" Marv
  13. Thanks, for a single image I am very happy. I am using a Nikon D3100 on a SW 150pds without any extras. So next clear night I am going to try for a big batch of these and see what stacking can achieve. I promise I will frame it correctly though as the third galaxy is out of shot for no reason. See getting picky already after one frame. Marvin
  14. I know just what you mean. Mine was three minutes which is pushing it on an NEQ5 and if you don't mind here is the end result. What do you think? Nothing done just a raw image.
  15. Rodd I love both of them. This is especially close to my heart as last night I took my first images of M31. If I can get close to your image one day I would be overjoyed. Marvin
  16. Just stumbled onto this thread. Great shot, you should be proud.
  17. Sometimes it makes me realise how far tech has come. Does anyone out there know when the first image of M42 was taken? It would be interesting to know when the image in this thread became roughly equal to professional efforts.
  18. Just finished reading the book Big Bang. I think I understood about a quarter of it. Your explanation of neutrino bursts from the sn makes me realise I need to read it again.
  19. It seemed like a silly question when I posted it, but this is very interesting and I definitely did not expect the difference of options. Was expecting ‘don’t be silly’ but I guess we are all a little in the dark when it comes to the real effects of Super Nova. On a personal note I have decided to view Betelgeuse with my left eye. If I get blinded by the explosion I have saved my ep eye of choice. Marvin
  20. I think that is a great result, considering that it is in effect a holiday point and shoot camera on a bracket clamped to the eye piece. In my opinion you have done very well. My own personal favourite is a moon shot I have using a Sony Cybershot in the same bracket as yours. It is my screen saver and I have been asked from where did I download it. Makes me smile. Marvin
  21. Welcome to astronomy b#####s. I have lost count of the amount of times I have laboriously pin pointed Polaris in the polar scope, adjusted for Polaris off set using the syn scan app, for the first star of choice given by the hand set to be so far out it is in another constellation!!! Drives me mad to the point that when the hand set asks to align to first star I always scroll to second or third option in the list as this ends up being more accurate. Just to prove myself wrong I have calibrated my polar scope and use an illuminated reticule eye piece and first star is always way out. Marv
  22. Rocked it dude. I have viewed Uranus once in the ep. Your pictures show far more than my eye ball could ever capture. Keep up the good work, gives me something to aim at in the distant future.
  23. Last night I was fortunate to get a second evenings Lunar observation, after missing the 7th due to complete cloud cover. I started with the most northern crater on the terminator which turned out to be Babbage, showing a crisp pock marked crater in the floor. Right next door Pythagoras with it’s central peak full of contrast. There appears to be a heart shaped structure joining the north wall of Pythagoras. I think it is the crater complex Anaximander finishing with Carpenter but hard to tell right on the edge. It is noticeable compared to the other craters that Pythagoras seems worn and badly erroded. J Herschel, very hard to see. A crater in the n/e wall and a pin prick post mark in the crater floor. Moving south to Aristarchus (pure white) plus Herodotus. I can now see Schroters valley, initial description ‘like a fish hook coming out of the mouth of the north wall of the second crater. At first I got confused for a few minutes thinking I was looking at Reiner and Reiner Gamma. Then I noticed the rock outcrop east and realised it was Montes Harbinger from the session on the 6th. Now I know where I am! West on the terminator to Selencus the shadow line directs it perfectly. A long wrinkle ridge glances Selencus east wall and continues to the Montes Agricola, I ponder if it is a wrinkle ridge as it is so straite, perhaps an ejector ray from a crater on the dark side? Schiaparelli has a large ridge that seems to fork at the crater. Moving south again, Hevelius with north companion Cavalerius appearing to clip the north wall of the larger crater, Cavalerius split black and white right down the middle. Hevelius showing a small sharp pointed peak, the floor has lumps and structure in the crater side wall. Looks a strait line on the outside of the eastern wall (map says rilles) going to need higher mag so I will come back this way later. Grimaldi is a monster with very complex crater walls, but really smooth on the crater floor like untouched Maria. The walls look eroded to the point of being blasted. Extremely rocky with what appears to be mountainous structure. Sirsalis, two overlapping equal craters, the older one clearly far more eroded. There appears to be lots of complex structure surrounding that area. Darwin, hard to identify. Appears to be a solid black figure of eight, so may be a double crater with collapsed joining wall? Cruder nearby and seems so shallow. Finished with Schickard which was not spectacular at this time. Time to up the magnification and head back to Aristarchus and Schroters valley. Now using a 10mm ep the valley looks like the letter W written by left hand (I am right handed) part way down the valley there looks like a split with one continuing onto to two small equal size craters. In moments of complete stillness this structure really blows me away. The central peak of Aristarchus is now visible and the wrinkle ridge/ray question is answered, it seems to be a massively long wrinkle ridge. I pushed it a bit further with a Barlow, but it seemed to amplify the seeing problems. After an hour or a touch more I decide to pack away and have a look at the Lunar 100 list that I keep hearing about Marvin
  24. Apologies if this is in the wrong place, mods please feel to move it to the right heading. Now this may sound silly, but if I were to be viewing Betelgeuse with my 150 pds at the moment the light from it’s supernova explosion reaches Earth would I be in any physical danger of eyesight damage. I thought don’t be rediculous, but after talking with an astronomer far more knowledgeable than I, his description made me wonder. I have read about a potential second sun in the sky, weak daylight on earth at night. I did initially think it wouldn’t be any worse than viewing the moon but it dawned on me that it is a concentrated point of light not soft reflected light from a surface. I ask this as we are aware of the dimming at present so perhaps we are getting close. Marvin
