  1. 6 years later I stumble across this golden nugget of information, which resolves the issues I experienced whilst starting to use mirror lock-up. Thank you
  2. Hello and welcome from another new member who has recently converted from the casual looking up to owning a scope. The learning curve is certainly steep and can appear to be over-whelming in the beginning, thankfully SGL is the font of all knowledge. I also highly recommend Wolvas for their online talks and of course the local support. I have already met up with a few members for observing sessions and have been exceptionally grateful for the help, support and encouragement given.
  3. With the age of my scope and my gorilla like approach to stopping things falling off, the thread has stripped in the holes for the tube-ring clamping bolts on my Celestron C6N, so I am exploring the option of using 'Helicoil' thread repair inserts. I don't have thread gauges or accurate verniers, so all I've managed to do is confuse myself: The shank is 1/4" but the thread is larger, somewhere around 0.3" or 5/16" or 1/4" The threads are somewhere around 20 tpi UNC? Does anyone happen to know, or is able to measure, the precise size and thread of the bolts please? I came up with 5/16th" 20 tpi UNC however, it seems Helicoils aren't available with those measurements? I have added pictures showing the clamping bolt and where it fits. Yes, it would probably be easier and quicker to buy new tube rings, but I am was hoping to repair instead. Thanks in advance. I am bracing myself for the all comments about being gentle with optical kit
  4. I need to attend this to return all the items left in my tent from March .... oh and also to prove that I do actually know how to align my scope now ! (note to self - pay attention to GMT / BST setting) Count me in
  5. These forum posts are timeless. I am researching adding a helical fine focuser to my Newt, so it's been great to find that someone has previously done so. I was cautious about the intended 'guidescope use' and also whether it actually fitted correctly.

    My Astrophotography

    My first half decent picture of the moon just using the camera (no scope). Only cropped in PS, no other alterations to image. Constructive criticism or advice appreciated, either for camera settings or PS to enhance. Canon 500d with 55-250mm STM lens. F5.6 1/160s ISO 400. Handheld, manual focus, single shot.

    My Astrophotography

    A visual record of my progress from total novice
  8. I am happy to report that the extra night was definitely with staying for, very clear skies as forecast. I managed to get aligned well, so was able to take a tour of some of the double stars, then went on to a few stars of interest to me before finishing off with a few Messier objects. I had a great time observing but when ice formed on everything I decided it was bed time (11pm) So that officially closes PSP 2020 and all that remains is for me to thank everyone involved in the organisation of the event, thank those that made it along and wish everyone a safe time until Corona is over. Clear skies !!
  9. I am overwhelmed at the kindness, generosity and support from everyone at PSP, thank you for making me feel so welcome. Your gifts of food, beer, heater, warm clothing, planisphere and astronomy knowledge are so gratefully received. With people leaving through health or needing to be back home for family, I am the sole survivor for Sunday night. Hopefully the predicted clear skies will materialise and I get my first proper viewing in a relatively dark area. Looking forward to the next start party....
  10. Thanks, that's the impression I got. Time to load car ..... it's
  11. Before I load the car and head off to Derbyshire, can we confirm that PSP is still going ahead please?
  12. Thank you in advance, all of those would be greatly appreciated, I really hadn't expected all of this to be on offer.
  13. Myself and SteveWolves are both still down to come. We are currently consuming alcohol as it's rumoured to kill covid
  14. Hi Chris, I have recently joined SGL and just found this thread. I am in Newport (Shropshire), which in our rural area makes us near neighbours Having only just bought my first scope I am still finding my way with it all.
  15. Thanks Geoff, the Cambridge site is is a great way of trialling Turn Left before buying.
