  1. Will do. In early autumn I compared the SW 32mm plossl to the 25mm BST in my 150 heritage dob (which is a quite fast f5), and find I actually prefer the plossl ,it seems to give better shaped stars at the edges, and the apparent field of view the two EPs offer is practically the same . I've not repeated the exercise in the far faster mak or the st80 yet , too busy enjoying finding new objects in the sky to look at in the short clear spells on offer over this winter ! Heather
  2. Oh, forgot to say, there is some padding to the bag , maybe a couple of mm of closed cell foam, it does afford some protection from knocks.
  3. As it may be useful to someone else, what with this tiddler of a 'scope being so eminently portable, I thought I'd post a couple of photos and a link to the bag I bought for mine. The photos are of the bag on top of the packaging it came in, with the st80 not even properly closed down for safe transport : the focuser wound part out, diagonal & EP still in place ...I just wanted to see if it would fit or should it go straight back. The RDF had to come off, but it fits in the bag lying on the focus tube. The bag handles are well sewn in and strong, a continuous band running under the ba
  4. I've really enjoyed the brief forays outside I've managed with the st80, it is ideal for swift deployment when an unanticipated break in the clouds happens and doesn't look as if it will last long : carry it out, extend the tripod legs , whip off the caps and go. I've left a 17mm 'super plossl' more or less permanently in it I'm rather attached to that plossl, it was my first supplementary EP purchase, and really pretty darn good for £20, but not getting much use in my other 'scopes now I have some BSTs . I've also used the 2x barlow (which I simply dislike using in the mak or dob for no
  5. Dear lord, and international moose/elk incident would be a serious thing , those perishers are large and somewhat likely to kick back , as quite a few random hikers and idiots attempting to hand feed or acquire a selfie with the 'cute' creature have painfully discovered. But they do have a place in the history of astronomy , search out 'Tycho Brahe's moose' online ...
  6. No need for sticks, just get yourself a beer tray, as wielded by the excellent dog rose morris
  7. Thanks for that, I tried the maths for the little Orion st80 I bought second hand recently , and got a (rounded to the nearest cm) number of 45cm , which just happens to be the exact diameter of the smaller cap-within-a-cap hole in the lens cover . Almost as if they knew Heather
  8. I assumed so too , this was the first link my search threw out https://www.skyatnightmagazine.com/reviews/telescopes/sky-watcher-star-discovery-150p-go-to-reflector/
  9. This site is a few years old, but has some useful insights http://washedoutastronomy.com/washedoutastronomy.com/content/urban-galaxies/index.html And I've posted a link to the Loughton list several times in the past, one more can't hurt : think of it as a free printable to keep you busy until you can get a copy of the excellent ' turn left at Orion' . You don't give a location, so I have no idea if the fact it has UK season references is a good thing for you or not . https://las-astro.org.uk/docs/Loughton_List_v2_0.pdf
  10. That was a long gestation period, hope the delivery goes well !
  11. I've managed a good few DSOs from my bortle 5 garden with a 150 dob, so don't give up ! I'd try without the filter, I'm not convinced they are effective with modern LED street lights. Do allow plenty of time for your eyes to dark adapt : I need about half an hour, but it varies from person to person. Only use a very dim red light if absolutely needed for tasks (to be honest, in bortle 5 the sky glow is usually enough for most purposes !) Even a moment's bright light will mean you have to start your dark adaptation all over again. Train yourself to use averted vision, looking to
  12. This thread is well worth reading: Many folk like zoom eyepieces, but every and any choice of optical equipment involves compromises, and my personal prejudice ( after decades of experience with photographic lenses) is for primes, As wulfrun says, the stock 25mm should do fine for the moment, no need to upgrade that instantly. I'd suggest waiting until you have used the 'scope a bit to make the decision where to spend your £150, it may well be that your experience with the setup points you to something else which needs an upgrade in that initial extras budget : I think the 150p is
  13. If the finder alignment is the problem , here's a link to the step by step 'how to' I typed up for someone else : they had a red dot finder, if yours is an optical finder (like a tiny telescope) the process is the same, just centre the view in the finder rather than a red dot. Heather
  14. In which case , as Arthur D. said,the world's your lobster ! And I have nothing useful or specific to add, only admiring such expensive toys from afar but I'm sure plenty of other folk will have suggestions based on actual experience ! Heather
  15. Here's a low tech way to check : if you happen to have any old 35mm plastic film pots around, one will fit easily inside a 1.25" eyepiece tube . Heather
  16. Yep, weird shadow post evaporated from the original , but still visible where I quoted it ! Heather
  17. Wise words ( some weird formatting going on there tho' : I seem to see a 'shadow post' below the actual one ! Did you use the edit option from the 3 dots to the top right of the post ?) Very local conditions can make a big difference, one street lamp and some houses with bright outdoor lighting several streets away scuppers my view for about twenty horizontal degrees in the WSW from my garden : the sky is noticeably brighter there, and I know any target in that patch below about 50 degrees altitude is simply not worth looking at, so if possible I try to catch it earlier when it is furth
  18. The original asking price on that was £36, Alan has them brand new and in stock for £43 plus P&P, so not much of a saving, which I think is why it lasted longer than the usual few minutes ! Heather
  19. Cleaning the car ? Cleaning the car ??? An activity just as likely to cause rain clouds as getting the telescope out is ! I suggest putting away or carefully covering all garden furniture , taking in the washing, and buying an expensive new waterproof jacket online . Should be dry and clear for days ...
  20. There was ... it sold (after being unsold for far longer than they usually are on here because of a slightly optimistic asking price ...) Alan at sky's the limit has stock : https://skys-the-limit-108154.square.site/shop/1-25-bst-starguider-ed/8 But if the OP is seriously considering an ES 82 , they may want to spend more ...
  21. You will get more helpful replies if you say how much you are willing to spend ... Heather
  22. I use something similar, mostly because I'm thrifty (or possibly just mean) and had a lovely little maglite solitaire (bulb version, I imagine the newer ones are LED ?) which had become redundant through acquiring brighter more efficient white light torches for non astro use.. Rather than just buy something new, I cut a circle of red acetate and stuck it to the lens with PVA glue (which is white, but dries to transparency) .One layer of acetate gave a nice bright red light ... too bright in fact, so a second disc went on top of the first. Now the light is dim, very dim, but it does not a
  23. When comparing the two remember that one is a planet where you are seeing a rocky surface with dark markings through a very thin atmosphere, whilst on the other we see the top of a reflective atmosphere of hydrogen & helium. Also, whilst the sizes shown are no doubt accurate mathematical comparisons, don't forget the solar system s dynamic, and the apparent size to us of a planet depends on where it is on its orbit compared to ours. Mars was close enough to Earth in the summer for even my beginner telescope and cheap eyepieces to show me several surface features, including what turne
  24. I think there's a bit of confusion creeping in here between the collimation screws (big , primary) , the lock screws (smaller, primary) and what Jasonb refers to as the tilt screws, which I think are the ones connecting the secondary to the spider ? Ha, beaten to it by Pixies ! I find Gary Seronik's guide https://garyseronik.com/a-beginners-guide-to-collimation/ clearer than the astrobaby one.
