  1. The Baader Classic Orthos / Plossl / 2.25x Barlow set compared with Baader Genuine Orthos (and a Circle-T ortho here and there !) Introduction As explained below, the weather conditions in the UK in the early days of 2013 have prevented a really thorough examination of the optical performance of these eyepieces. However, I wanted to post something that might be of help to those considering them so I’ve compiled these notes on what I've learned about them so far. This should be considered and interim report really though so please bear that in mind. Where I use the abbreviation BGO I am referri

  2. I think I know why our weather is so bad.. You see, Tony, you landed here and opened your scopes and let out all of the cloud, now, you've flown back with the cloud no longer in your scopes, but next week it's flying over to catch you up .

  3. I own, or have owned a lot of refractors...............the Tal 100rs is still optically the best achromat i have come across in the 4" sector , the field is sharp as a tack across the whole field, stars are super sharp right to the edge, unlike chinese 4" achro`s, i own a 3" f16.5, a 4" f10 (tal) and a 105mm f15, of these scopes the Tal has the best optics

  5. Last summer whilst drooling over the beautiful looking telescopes on the Sumerian website I suddenly had the urge to ask permission for a 16" Canopus and to my suprise she said yes! Well it wasnt quite that simple as we then went through the whole haggling process as to how many pairs of shoes she could get if I got the telescope. I couldnt find alot of info about the Canopus model on the net so I started talking to Michael at Sumerian via email asking for details. He came back quickly with lots of details, advice and was very helpful right from the start. After a couple nights mulling it over

  6. There is some amazing lunar work on this forum. Kudos to you all for some very fine work. I am mostly a deep sky guy when it comes to imaging, but I thought I would try my new Pentax K-01 on the Moon a few nights ago. I still have my old T-adapter from shooting prime focus film and it fit just fine to the new Pentax. The old 8" SCT still performs well after thirty years. I added the reducer / corrector to the optic and it pretty much takes care of the crop factor the APS-C sensor takes from the field compared to 35mm. I shot this in RAW format and processed in Photoshop. 1/400 Second @

  7. I've had a 200K side by side with a 8" sct and the view in the former was more pleasing.Tighter star points, brighter image. In fact I sold myvery good quality, Intes 7" F10 Mak-Cass, as my 200K bested that, which surprised me. I've had my awesome Carton 60/1000 next to my Alcor(65mm Newt!!). The newt kept up with the renowned Carton lens. No small feat. Virtually no plastic on Tal stuff. Steel n aluminium. WILL last a lifetime. Optically excellent, both mirrors and lenses. Being in the military optics game, helps, I guess, with the super tough coatings. Scopes come with accessories that are

  8. Here's a lagoon and trifid shot i did with my 200mm 2.8L and 1000d to compare with the above shot. The Canon 200mm f2.8 is alot cheaper. And with NB and the chip size of your 314 you can use f2.8 no problems. With a dslr f3.5 and an external aperture mask clean it up perfectly. And whats more is its an awesome daytime lens!

  9. Hi Rob, I think a filter with an area of 165,200,000 km2 would be slight overkill Sorry couldn't resist Seriously tho, either of the standard filter sizes will be fine (1.25" or 2") of any make. It's quite obvious that you need 2" filters for 2" eyepieces but 2" filters also have the bonus of that some 1.25" adaptors have filter threads so you can attach the filter to that and change eyepieces without removing the filter. I do this

  10. Hi everyone! Well here I am, like a coiled spring, with my newly unpacked Skywatcher Heritage 130p, Barlow, Planisphere and TLAO on order - Stellarium on the computer and Star Walk on the iPad... All the gear and no idea! I blame Brian May. I had decided on the Dob 200p, but my lady convinced me of the sense in starting small and proving interest first. Obviously not a good night for the new hobby (well OK it has just stopped snowing), but I cannot wait to have a first look at the skies - and by the look of it I am not alone. There cannot be many left in the UK still to sign up! I have alway

  11. I'm glad Starsteve posed the question. Very interesting to see the responses. I feel like Tony said, and as Steve put it, that there IS an emotional aspect to how I respond to my telescopes - and this in fact has influenced my selections. And I think that this is right - I should have some engagement on all levels with the instruments I use in the hobby I have invested so much money and time on (well as much time as the cloudy skies of Yorkshire permit...). The first scope I bought was a Celestron 8SE. This clearly offers much more in terms of what I can see than the TAL100rs on EQ5 I bought l

  13. Here's a recent image made using the Borg 60ED f4 and a modded Canon 450D. Other than that picture from the DigiBorg blog I am not going to try to influence you towards buying a Borg over a DSLR lens but this discussion is far too interesting for me to stand on the sidelines because it is something I have been pondering and having spent two decades working in photo-retail (prior to FLO) I can see how both optics are attractive. Convenience and practically aside, it is difficult to make an objective comparison between a Canon EF 200mm f2.8L II USM and a Borg 60ED f4. The Canon lens comprises ni

  14. Just realised why they make the SkyTee & Giro style twin alt/az mounts........so we can mount a TAL100R alongside a TAL100RS! Edit. I say just realised but I confess to recently having taken a close interest in a 100RS which just sold on eBay, and I'm very aware of the cost of a SkyTee & tripod from FLO.....ahem..... Edit 2. Oh, and I didn't get it in the end!

  18. I expect that Brian May will read this forum and probably even has an alias I fully expect that he knows that he is one of the UK astronomers' heroes and that they would be proud for him to take the reins, even if it was just to hand over to another of his colleagues in this time of uncertainty. I have spoken to fellow astronomers at the star parties that have spoken to him and they speak so highly of him. Perhaps he could just do a slot on the new program, even? An equipment review or share an experience? Like the post if you agree!!

  22. You're making a big mistake in calling the mount a tripod. The mount stands on a tripod but the tripod is dirt cheap. What the mount does is track the sky with utterly phenomenal precision once using an autoguider. I mean that in a thirty minute exposure you might have a tracking error equivalent to a fifth of a pixel. Think about it; that is incredible and very hard to acheive and utterly essential to a successful photo. There are people on here using mounts costing £12,000 so that makes the HEQ5 a bit of a bargain. (I'm going to go against the grain and say that the HEQ5 is perfectly adequat

  24. I've got to say that I think that the team that supported SPM worked extremely well, Chris Lintott and Chris North with their scientific background add gravitas and stretch you and Paul and Pete make a great team explaining the night sky and photography. I also think that Brian May has added an awful lot to the programme and I really like his approach, and would like to see more of him in the programme. Jon Culshaw is great for the laymans' perspective. In short, I vote for keeping it the way it was for the moment and I'd hate the idea of it being 'brought up to date' or other such nonsens

  25. Hmmm. Following on from Michael's post, a three or so more musings from someone who cannot make an informed decision, not having owned anything else and only having spent a short time with a TAL-100R: 1. http://www.lada-owners-club.co.uk/index.html ... maybe not the best comparison, but there is something that attracts people to certain things that leaves other people just scratching their heads. TALs go with my personality 2. Many members of the SGL community who are not particularly TAL-oriented but have owned and evaluated many different scopes often lament about the TAL-100R or RS they g

  26. Good morning everyone! Long time no type! Last time I had the scope out was the beginning of January! My nan had been pestering me to let her have a kook through the 200p beast. The weather hadn't been the best and this particular day was no exception. Cloudy, misty, foggy and damp. To cut a story short, at about 20:00 it completely went clear so I let the 200p cool and got ready. 30 minutes later focussed on Jupiter and let my nan help herself to it. "oh my god. That's amazing. Oh my god" They were her words. She's been in to astronomy (reading and watching programmes) for years. She was a

  28. My moto is if it aint broke don't fix it, keep the show as it is because it has worked all these years. Ok it will never be the same without SPM but if you started to put big shouty celebs on there I can see the budget going through the roof & then the show being axed. With technology these days if kids want to watch it then it's repeated on BBC4 or it can be watched via iPlayer . May it continue for many years to come.

  29. As mentioned in previous posts, and i asked the question elsewhere on this forum, I totally agree that the current line up is just right, I would think that Brian May would probably let the BBC continue to air the program from his house, and I am sure that he would like to appear sometime, but he would say h is not the right man to front it. Keep the format the same and the presenters the same. I will be looking forwards to see what the BBC show in February and if they dedicate the program to Sir Patrick Moore. I hope they find wisdom and continue the program for eternity , there are so many p

  31. I absolutely agree with the comments that the Beeb should retain the services of Chris's Lintott and North, Pete Lawrence and Paul Abel. They don't all have to be on each month, but maybe rotating them around could be an option? As everyone has said, no one can ever fully replace Sir Patrick, but I sincerely hope they keep the programme going if nothing else as a mark of respect. After all it is only 20/30 minutes once a month. I don't know what the production costs are, but surely the Beeb can afford to spend our license money on something that is educational and that a great many people real

  32. Having decided not to keep the Antares f15, i wanted a replacement, some thing not quite as big, but a long focal length achromat, so i decided to look out for a Prinz 660, the idea was to find a slightly tatty one, and modernise it a little, with crawmach focuser and new paint job! but this rather tidy telescope came up as a result of a wanted add, frankly its just to nice to alter, so i will use it in standard trim. Its a 76.2mm f16.5 1250mm focal length achro, same as a prinz 660, but withy a different name on it, ST Astronomical, made in Japan, with the circle K optics logo. The optics are

  33. Hello! I recently discovered the stargazers lounge and thought it would be rude not to introduce myself! I am Lucy, I live in Taunton, Somerset and like many hundreds of other folks have enjoyed the recent Stargazers Live episodes on the BBC. I am new to this and look forward to exploring and learning in the coming days, months and years about the skies above us! I have been enjoying reading Mark Thompson's Down to Earth Guide to the Cosmos. Any other recommendations? Take care in this snowy weather.

  35. SGL is invaluable for advice on any aspect of amateur astronomy. Just hang on, I'm sure someone uses precisely your setup with and without the added motor drive. Tracking opens up several interesting uses. Then you'll find that tracking isn't good enough, so you'll start guiding. Then you'll find that guiding isn't good enough, so you'll get a better mount. And so on and so on ! It's never ending once you get the bug ... /Jesper

  39. Nice start! If your DSLR is not modified for astrophotography, it is not that sensitive at the hydrogen-alpha wavelength, which is responsible for the red colour. Modifying the camera can increase the sensitivity at that wavelength by a factor of four. Longer exposures with an unmodded camera can reveal more.

  40. Hi Everyone, Thank you all for your comments. I appreciate the "diplomatic" approach and will tread with baby steps. I am lucky and have 4 clubs with in reach from my home (Chipping Norton, Stratford on Avon, Cotswolds Club in Cheltenham and Swindon Stargazers). I will contact one of these and try to get along to one of their meetings. I appreciate that the final decision will have to be my own but it is nice to get varying opinions from more "experienced" people like yourselves. I suppose buying a 'scope is like buying a car performance against price, quality against economy. Graham

  41. Hi Shecks If the sky's clear, it's probably worthwhile setting up - you could try fashion a make shift dew shield from cardboard - a couple of cornflakes packets taped together might do! Better if it's black but if not at least you will still get to use your scope. HTH Paul P.s. we have all to few clear nights, use them when you can.

  42. I find the TV Sol-Searcher that came with the LS35 to be ideal for pointing the scope sunwards. No messing with goto (but then, of course, my mount has no goto ). I also find that polar alignment can be quite rough. Just point the polar axis northwards, and level the mount gives me sufficiently good tracking to snap a bunch of frames. For solar scopes with longer focal lengths some finer adjustment might be needed.

  46. I use the GoTo on my imaging rig (NEQ6) mainly to save time when trying to find and centre something, that is too faint to see visually, on a very small chip area. I wouldn't be without it now. I found it intuitive to use. The first alignment star is normally a few degrees off, but I have a Rigel QuickFinder fitted so it only takes a few seconds to get it in the right area. I have had a couple of times when it went off in the wrong direction for no apparent reason, but a quick re-sync / re-centre and all was well. Most complaints seem to boil down to operator error or biased opinion from the a
