  1. Hi all. I have googled around and can't seem to find an answer.to this basic question. Having found it near to impossible to get snapshots through the eyepiece, I bought a T adapter and attached my mirrorless camera to the diagonal and testing it out in daytime it was great to see how easily I could get focus, the camera seemed to default to MF, but it would not fire the shutter! I'm guseeing it is lacking information from the lens that it requires or some such thing? Do I need to set everything manually somehow, I'm a bit of a scene selection auto/fully auto shooter.... It's a new camera I'm not too familiar with all the digital menus etc. It's a canon EOSM100. Anybody know what I need to do to make it fire the shutter please? (I'm not ever going to get into serious astrophotography, strictly the moon, planets and maybe a glob or two, I'm not technically minded, as you can tell) Thanks folks Clear skies, Dave
  2. Thank you very much! I heard the series 5000 has 60 deg and "comfortable" eye relief? I think I'll go with bst.
  3. Thank you. I'm stuck between a super plossl and a starguider and can't decide. I know I love a plossl and the BST's seem to good to be true at £49!
  4. To be concise, what is better, a series 5000 plossl or a bst starguider, for planets, bright globs and double stars in a 127mak? I'm thinking of between 9-12mm max as my skies are generally poor and I've rarely been able to go much higher than 150x, or even go that high. Alternatively are there any better suggestions. I'm interested in comfortable fov and eye relief, I'm not using tracking. Thanks everybody Dave
  5. I hope this isn't out of place on here. I have always wondered so I thought I'd put it to the forum.......whydo many large Maks even up to 150mm, feature the dovetail bar on the side edge of the ota, when surely it makes 100% more sense to place this on the underside, in terms of balance and just common sense really it seems a bit nutty hanging the ots from one side of the mount and tripos when clearly it should be atop and central to the whole setup? Just seems so daft. Any thoughts or explanations anybody?
  6. These are becoming scarce with just the 15mm and 20mm available in 1.25" . I would love to get hold of a 15mm. Will @FLO be stocking the 15 any time soon please?
  7. I'm after a star diagonal to replace my Tak prism. The problem is the twist lock. I use Baader Hyperions and Baader zoom and I keep on twisting the wrong part of the setup. Hyperions come apart and of course zooms zoom so I want a diagonal with retaining screw. I've seen one on Amazon that looks like quality for under £10. Is this a case of when something looks too good to be true, it probably is? or does anybody have experience with one of these? I know with diagonals you need to pay huge sums to imake tiny improvements but is this thing going to be just too cheap? I'll post a link as I believe that is allowed. https://www.amazon.co.uk/Dielectric-All-Surface-Multilayer-Telescope-Diagonals-default/dp/B08KRLHRHG/ref=sr_1_1_sspa?dchild=1&keywords=dielectric+star+diagonal&qid=1624979072&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExM1Q4Tk5HR1RVWEJWJmVuY3J5cHRlZElkPUEwMDI3NDM5VzhMNjJOV0lSVVhQJmVuY3J5cHRlZEFkSWQ9QTA1ODczMDkzSjFUNk1INk5NUVFQJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ== Cheers everybody. Come On England
  8. I don't think it was actually, but that looks very interesting as well!
  9. I'm sorry to post this but I have used the search function on here and got no joy. I do remember news of a june launch of a 1.25" zoom, approx 7-21mm with a 70 deg FOV at all focal lengths. I cannot for the life of me remember the manufacturer and I can't find anything on google but I do know it has been mentioned on here. Can somebody please remind me and does anyone know if it's still expected to be available this month because it sounds hugely exciting? Thanks Dave
  10. This might be a ridiculous question but.......I have a solar filter and I'm enjoying being able to enjoy astronomy during the day and in warm temperatures! I have seen that projecting the image onto a screen can create a large image that more people can observe and in safety so that seems like a great idea. My question is, can the same method be used with the moon, after all the moon is extremely bright in the telescope. Do people ever project an image of the moon onto a screen? Or is it a completely stupid question? Cheers dave
  11. I have purchased a sheet of Baader solar film to make pair of solar filters for my Canon 15x50 IS binoculars. I had intended to modify some pop up objective lens caps, outer diameter 70mm, by making 2 circular cells with 50mm central openings, out of the film and stiff card, then gluing them to the inside of the lens caps which have a good 25mm of depth, so that the cap can still be closed and protect the film when not in use. That was my plan, However the film comes with instructions showing an overlap around the objective lenses which could be square or circular. Is it necessary to have this overlap, considering that with binoculars your eyes are looking directly towards the Sun, whereas with a telescope they are not? The issue is that the 15x50 objectives almost touch so there is no room for any overlap. I would need to make a rectangular or oval shaped filter? I do have another option which is to make filters for my smaller 8x30 Nikon Monarchs, or even for a cheap pair of Nikon 8x42's? or should I go the whole hog and make a filter for my 127 Mak. Does aperture or magnification matter when observing the Sun? I hope that's not too confusing I have tried to be as clear as possible. I am torn because I love the 15x50's, the objectives do not move so a single, rectangular filter would probably be the solution? Thanks everyone for any advice. (Of course, safety is the most hugely important issue!!) Clear skies Dave
  12. I know fall back spring fwd, I just don't understand the term "Daylight Saving Time"! My Synscan init was correct anyhow, thanks!
  13. Yes cheers I will have to find that level and north option then. I did watch some youtube vids and they seemed to suggest that it wasn't critical. I know a lot of constellations but names of stars I am poor I'm afraid, very poor.
  14. Thanks. I can see the point of using stars rather than the moon or even planets to get an alignment! I just don't know the names of too many stars. I guess I'll have to get the laptop out to be sure I am looking at the right stars.
  15. Thank you, this raises the question (shows how little I know), I am levelling the ota, not the mount! Schoolboy error?
  16. I just mean that mounting bracket on the ota that's sort of wedge shaped and a single albeit large thumbscrew on the mount holds the ota in place. There was definitely a bit of give there. I use the handset because I couldn't get on with using the app on my phone but I use an app Synscan init to set up the scope. I'm never sure what daylight saving yes/no is supposed to mean. All I know is the clocks went back about a month ago!! Thanks.
  17. Since buying some Canon 15x50 IS, I haven't used my scope much, and I've shied away from the technical stuff, star alignment ets. as at first it just didn't seem to work very well. I took it out last night for another try. 127 mak on azgti wifi with hand controller. Set level and north, input co-ordinates etc. etc. It wasn't yet properly dark so did a daylight alignment using just the moon. Tracking worked great, which is the main reason i bought a motorised mount. GoTo was poor, asked it to slew to Jupiter and it placed the planet within the 10x50 finderscope but not in the 24mm hyperion FOV! I expected it to ask me to centre Jupiter in the FOV and confirm but no, it didn't so......Asked to return to the Moon, and it had no problem! Same thing with saturn and Mars, was outside the FOV. I won't be able to locate faint DSO's if they aren't even close to the center of the view in the finder! In my skies it's quite difficult to find them at the best of times. I did later notice a bit of slop which was the OTA moving a bit on the wedge that holds it to the mount so maybe next time I need to tighten that thumbscrew? Any thoughts anyone? I have to say the stars look so gorgeous in the binoculars and the colours come out beautifully and it's so effortless to just sweep around and take it all in, but i have this expensive telescope and I'd like to get a bit more use out of it! Any advice gratefully received thanks for reading.
  18. thanks. the 15x50's arrived yesterday. for me, and its a personal think with binoculars, these things blow the 12x36 out of the water. My concerns were after reading on the web, the eyecups, the weight, the fov....nope...no issuee, I Iike these things they feel nice and comfortable, the fact you can press and release the IS button is a MASSIVE plus for me makes them so much easier and more comfortable to hold. Only caveat, the focus does seem to drift in and out with the is on but if you twiddle the focusser out then in again it seems to settle down....anyway.........these are amazing things.
  19. So, I may be talking to myself on here but another update on the Canon's. I went out walking on a hot day yesterday, and I took my Nikon Manarch 8x30 with me. I didn't fancy taking out the Canons as I like to travel light as possible and the Nikons hand from my belt strap in their soft pouch. That told me all I need to know about the Canons as a pair of all-round use bins. So if they are going to be just for Astronomy and very occasional use in the field, I may as well have gone for the 15x50, for the extra aperture. So I am returning them and exchanging them for some 15x50 is! I shall report back again when they eventually arrive..................
  20. Finally a gap in the clouds on a day when I haven't got a 4am alarm call. Took a look at jupiter and saturn and a few milky way constellations (Cygnus, Cassiopea. It was not fully dark before the cloud blanket covered the whole sky but meanwhile: Beautiful pinpoint stars, lots of double stars and colours showing up well. The best views of starfields I've seen in binoculars. Jupiter showed a large disk, no bands visible, perhaps a bit too bright? 3 moons clearly shown, biggest surprise of all, Saturns rings showing quite clearly which I did not expect at 12x! Tiny yes but clearly showing. This is not my imagination is it? Because I know what I'm looking at I wondered if my brain could be doing this to me? I swear I could clearly see the tiny planet and the rings. Hoping for better skies tonight but what we really need here is a storm to clear the air. Clear skies all Dave Btw I found some fab objective lens caps for the Canons on Amazon uk! 37mm opticron fir perfectly and quite nice quality soft rubber. The retaining O rings are loose due to the tapered barrels of the bind but that's not an issue to me.
  21. Today, I took the both bins out, just birds and planes and rooftops, usual thing and did a proper side by side comparison, Nikon Monarch 7 8x30 vs Canon IS 12x36 and I changed my mind. the colour fringe is there in the nikons, it's just less noticeable, and everything else is less noticeable in the Nikons, the Canons in terms of resolving detail are a world better, and with the batteries replaced for Energiser ultimate lithiums the view seems almost like tripod mounted. What you can see observing a pigeon on a nearby rooftop well there is no comparison. You see the pypils of that bird like it's sat on your arm it's mad. All clouded out still so awaiting a look at the moon or stars some time soon.
  22. Finally my Canons arrived, they have been so out of stock during this lockdown. It's thick cloud tonight but I've had a chance to play with them before dark and I'm slightly underwhelmed. I owned some of the original square chunky versions back in the day and was amazed by them but since then I have purchased some Nikon Monarch 7 8x30 bins and optically I think those are far better than these Canons for less than half the price, plus smaller, lighter and with a wider fov. The Canons are showing a lot of colour fringe around anything against a bright background, I'm used to better. The stabilisation is great and definitely makes a difference in terms of seeing detail but it's not a 100% steady image, definitely not like tripod mounted bins. I need a clear night to check these out on the night sky where the Nikons are pretty much useless as you need a steady image for astronomy and I can't hand hold them. I probably expected too much. I do remember being amazed by the original 12x36 is but I didn't own the Nikons at that time! I'll get back after I've had more time to evaluate and consider the advantages/disadvantages. Cheers Dave
  23. UK Heads up. Tonight we have the moon, jupiter and saturn lined up beautifully and the ISS will pass directly across the face of the moon at 22:36:20. Times may vary depending upon your location but not by a lot. Check Stellarium. Clear skies, enjoy. Dave
  24. To be fair I'm not sure my Skymax 127 can take any higher mag than 150x in normal circumstances, so I'd really be looking at the zoom as a 10-20mm! Still, with the 24 Hyperion and then the zoom that does cover every focal length I ever need. I still think I'll be looking out for one, maybe a used one.
