  1. JOC. I get your message entirely, well said. Perhaps I was too strong in my opinions and voicing them. If so my apologies. In a more measured way I was trying to say that the challenges can sometimes seem like an arms race. And if an SGL’r doesn’t have a bunch of post processing software and the knowledge to use it, it can seem pointless to enter the challenges. After reading my post I want to apologise to Grant. You seem to have enough on your plate without someone (me) deciding on a unilateral boycott. I have looked through the mirror the other way and decided to enter any future challenge if I can meet the criteria. It was pointed out to me that perhaps that is how the winners got their mugs. Yeh.... my wife was right. “Stop moaning and do something about it” M
  2. Ahh nice one, they go by far worse language in my house. Heavens know why, they keep the monsters from our doors. Might be a legacy of family stories, due to the fact that my grandfather may have worked for the Richardson’s. Could just be a healthy distrust of authority. Got to keep free thinking alive. Can you imagine what Galileo must have lived through? Let alone Copernicus?
  3. Thank you if you could that would be great. I did think about running back to the house and grabbing the tripod and DSLR but the clouds were moving quick so I knew it was just that moment in time. like a night time circular rainbow round the moon, a first for me, but I have only been at this two years so I thought I would ask the question.
  4. Just working out who is who. Who is plod? Unless I am missing something they are are not part of this thread. I assume that Paul is Paul M, but I am still confused.
  5. Good stuff, I hope you see a few in your lunch break. As for the question? Perhaps but the chances are that the moon and exposure rates for lunar photography just wouldn’t pick it up. Bit like trying to photograph Mercury, much better in transit or by orbiter, I would imagine it is possible with a sizeable bolide, but when does that come along and crossing the moon!!! not to mention at night in the northern hemisphere. perhaps it should be one of the SGL challenges. Could run longer than time itself. Marv
  6. If the skies are clear you can count me in. I will stand in the freezing cold for a meteor shower no matter what. Sort of an unofficial club for night sky lunatics that don’t even need scopes. Could get you arrested for loitering in some places. Try using astronomy as your defence in court and see how far it gets you. Those binoculars will add five to your sentence. M
  7. As a leveller the persons own back yard might Snowdonia and yours inner London, hardly a level playing field. I know there is no such thing, but I feel that software for the beginner is exclusive not inclusive.
  8. As it is caused by the moon I thought I would post it here. Heavy winds and heavy rain here yesterday which cleared to blue skies and horse tails into the night. Didn’t get the scope out due to the full moon, but took the dogs Marvin jr and Lexy up the lane for a walk. A huge high piece of horse tail crossed the moon, very thin but like a work of art. The moon very bright had a halo five moon diameters in circumference, and a further four moon diameters of the bands of the colour spectrum. I realise this is a circular version of a rainbow caused by second hand light reflecting off the moon back through the ice crystals of the horse tail. What surprised me, other than how beautiful it was, was I that I think it is the first time I have seen this phenomenon. Does anyone out there have a name for this as it stopped me in my tracks. Marv
  9. I like the idea of the one above. How about adding an extra dimension. Just what you captured! No stacking or computers allowed. Just the single original image. Might be a leveller for us, might not be spectacular, but those of us without a server in the basement might actually want to enter future challenges. I entered my first shortly after joining SGL (Lunar terminator ep pic) and quickly realised that the challenges were purely photographic and I had neither the kit nor the photoshop know how, let alone the program to get even close. Sorry Grant, but I will not enter another as I know I am under gunned as at present I am a visual astronomer and I have seen what it takes to get a mug. They all deserved them by the way, terrific entries. Marv
  10. Yes I did get it added after the kind help of Jamesf. It was some time ago and worked first time. Perhaps one of those dreaded Microsoft updates has added a gremlin into the works.
  11. Any idea how you attach the brass DSLR? Let alone how you connect up the bronze laptop. Must have weighed a ton. Does rather put things into perspective though. In 1923 how many people had electric? But I am guessing that if you had 21k for a telescope you had shares in Westinghouse. Strange irony that the person with the scope probably had all the lights on to show off to neighbours, so there starts urban light pollution at the hands of an astronomer. M
  12. Yeh, lead balloon that crashed into the Pyrenees due to bad weather that goes on for ever, except in Spain it seems. Only joking, it’s just that I am quite close but have UK weather which is a long version of “I am envious”. Marv
  13. John, done us proud right there. Can’t stop comparing this picture with the over head from Johnturley. Never noticed the deformation in the right crater wall. Enlarged the overhead image to see the crater nearest to the close end of the wall. Doesn’t really show up on the overhead. Next opportunity I have a mission to try and see that magma rille to the right of the central crater in this shot. Can’t imagine what it looked like to the naked eye. Marvin
  14. The smell.. that gasoline smell. Smells like... smells like victory.
  15. Cloud sweeper. I was first light last night with a 150 pds. About 20:00hrs Rupes Recta was astonishing, the equal small craters either side symmetrical. Been a while since I observed Lunar, need to do more, so easy to forget it is in reach. Marvin
  16. Cheers, always interested in a local source especially as buying from elsewhere requires a monetary exchange. Thankfully I bought a big roll from FLO first time around so I think I have enough left over for the 150. If you don’t mind I am going to pm you. Reply if you want. Marv
  17. Got my new SW 150 pds yesterday and clear skies for first light and I loved it. Tonight, no cloud at all............ but pea soup thick fog. Really hurts that 300 meters above me it is amazing.
  18. The double ‘that’ was not a typo. It was a stutter because I want one.
  19. Not a reply to anyone of you in particular but I am gob smacked by that tripod. I am a love of the old school (not everything has to be carbon fibre) I know, you are all in the know and one of you has it in his or hers house, but some info to the uninformed would be nice. Who makes that that thing of beauty? Marv
  20. No intrusion, these questions are just what this part of the forum is for. To a certain degree your comment is quite true. Level your tripod facing north, roughly level the thing and get Polaris in the cross hairs of the polar scope. You have a rough polar alignment. However. If you require more accuracy in your tracking say for photography, then polar alignment needs to be spot on. As a basic the reticule in the polar scope needs to centred (already touched on). And using a phone app to tell you where to adjust your mount to in relation to the pole star is invaluable. The more accurately you can follow the app after following the previous stuff the better your alignment and tracking will be. The flip side is if you are doing a one hour multi target visual session then that much effort is far less important. Its up to you how much to sweat it. Marv
  21. Thanks for the advice, I will look into it. Small inexpensive changes I like. Going to use it for a few months then floc it, blacken edges and a light shield. Forgot to say that it was massively out of collimation. Thankfully I have a laser so in a couple of minutes all was sorted. I like to think that they are shipped with all the main mirror screws loose to allow the mirror some cushioning whilst in transit M
  22. Forgot to say before you loosen the grub screws unscrew completely the eyepiece to get access to the reticule.
  23. I had the same problem with my EQ5 factory fitted polar scope. Turns out they screw in the polar scope until it tightens and where ever the reticule ends up is your problem. You can change the position of the reticule by slightly loosening the tiny Allen key grub screws (three) and rotating the reticule until you have the 0 top dead center whilst the mount is in the home position. Be aware that if you loose too much the reticule will fall out onto the floor, plus there is some grease in there that you don’t want in your polar alignment view. Once rotated and gently fixed in place (don’t over tighten grub screws) you can have ago at centring the reticule. By using the grub screws in the same way as collimating a secondary mirror. I found all this on YouTube, so I am sure you will too. I certainly understand previous comments about perfect polar alignment not being necessary but a degree of accuracy can’t be a bad thing when we spend money on this kit. Marvin
  24. Happy birthday Stu. I took receipt of Skywatcher 150 pds today. I got a text on my phone to say it was coming so my lovely wife couldn’t hide it till my birthday tomorrow. Well happy, as the sky was clear for the first time in an age, finally flying in the face of buy kit get clouds. Such a small jump from 130 to 150 and what a difference. Despite the more than half moon I could see Andromeda better than ever before, far brighter core. Didn’t know it came with a 28mm 2 inch eye piece my first. Absolutely huge compared to my wee box of plossle’s. Marv
