  1. hey guys, im reallly new to this, and ive bought a celesron astro fi 130mm newtonian telescope. but i really dont know what should i buy next for making the observation more clear? any advices? thank you so much.
  2. Hi astropeeps Can anyone explain why the view through a 21mm celestron ultima duo eyepiece frames the moon perfectly, but when I attach the camera it acts more like a 18mm eyepiece and a third of the moon is out of frame? Do I need an extender of some sort or a better camera? I have a LUMIX G7, micro 4/3 mount. Cheers The Nut
  3. Hi Folks, I have a full set of Baader Hyperion EP's in black (purpose made) hard case For Sale Also included in the bundle are the two extensions rings 28mm & 14mm - Just research online what this complete set will give you in terms of power and eye relief. EP's are a great condition and I also have individual boxes if for some reason you want to box individually. So that's 7 EP,s Two extension rings and the Baader Hyperion Carry Case.... 24mm 21mm 17mm 13mm 10mm 8mm 5 mm £350 Collection from Birmingham preferred...
  4. Good day to all. I primarily observe with a Celestron C80ED, f/7.5, and a 150mm Newt-DOB, f/6. May I ask?..... I have a couple Celestron Omni Plossl eyepieces, 12mm and 9mm (newer China mfg). I also have 2 Meade Series 4000, Plossl, 12.4mm and 9.7mm (newer China mfg). And finally I have 3 older Edmund Scientific Volcano Tops, 12.5mm, 9mm and 7mm (1970s Japanese made). With the eyepieces, I use a TeleVue, 2x Barlow at times, which is an excellent performer. Seeing in my area has been so bad for such a long time, I can't seem to get a handle on which set might have an edge over the others. I've tried on several occasions to compare them side by side, however it is very difficult to do so under such conditions, though I'm hoping with the cooler weather better views may be had. I'm speaking primarily of quality in sharpness and detail for planetary and lunar views. I'm wondering if anyone has had a chance to use any of these brands - or all of them - and if you feel one brand or type would have an advantage, if and when good conditions present themselves. Any opinions would be appreciated. Thank you. joe
  5. Revelation binoviewer for sale, complete with two pairs of eyepieces. In very good condition, complete with original aluminium box, a pair of FMC 12mm wide angle eyepieces and a pair of FMC 20mm wide angle eyepieces. New from Telescope House the binoviewer alone is £125. For both sets of eyepieces plus the viewer the price is a mere £120, plus postage. Postage will be £8. Can also be collected from Victoria area of London.
  6. Would anyone care to recommend an 8 mm EP to complete my collection. Will be used with the 200 Dob and primarily for Planets. I really like my WO 6 mm but they don't make the 8. The Vixens are fine but again no 8 I am not a great lover of Barlows.
  7. Item on the BBS News Science & Technology site Flat lens promises possible revolution in optics See http://www.bbc.co.uk/news/science-environment-36438686 Apparently, using chip-fab techncology it should be posible to make super-quality lenses 30 cm dia or more for pence (cents). Big, cheap refractors here we come? Regards, Doug
  8. Have you seen the Bresser 70°-Series 6-piece Eyepiece Set for 250 bucks? I am after a 35mm EP, and the set has 2" 25, 30 and 35mm for less than any decent 35mm I have seen...what gives,? are they poor eyepieces? The 15mm would also fill a gap that I was planning to purchase a 14 mm for. Seems to good to be true, like when I found out about the 3-6mm nagler zoom with its yellowing effect,small field and not recommended for focal lengths over 900mm. The set has my interest.
  9. My telescope is the Skywatcher Explorer 130P GoTo Is it worth getting a 2.5mm EP for my telescope or a x3 Barlow lens. I'm asking because i would love to see mars and Saturn closer up for finer detail.
  10. OK, a little bored today, so I thought I'd line up all my EP's to attention. Half of them are stock EP's which came with various scopes (1st photo) , and the other lot in the 2nd photo are all EP's I've bought seperately. A quick run through of the guys are as follows (from left to right); 2nd photo; TMB Planetary II 4.5mm - Celestron Omni plossl 6mm & also 12mm - Vixen LV 15mm - Skywatcher plossl 17mm - Explore Scienticfic (2" EP) 25mm - Celestron Omni plossl 32mm 1st photo; Skywatcher stock 4mm and 2x 10mm - Celestron Stock 10mm, 20mm, 20mm erecting EP - Skywatxher stock 2x Super 25mm Plus I have two other stock EP's from a scope in the loft which are also stock Celestron's to at 10mm & 20mm EP's. To be honest I surprised myself how many I was awash with EP's! Hehe! I'm sure other members can outdo this shady mob of EP's too! OK fellas! Stand down now! Oh! With three pairs of the same stock EP's, I'll be in good shape when I buy a binoviewer at some point later on this year too! Edit: sorry the order of the pictures uploaded came up wrong, so edited to reflect that.
  11. Well I just now bit on my first expensive-ish 35mm panoptic Televue Nagler eyepiece on Ebay. I've only ever owned 1.25" cheapy Plossl lenses that came with my Dobsonian, but I recently bought a nice little refractor that allows for 2" eyepieces. Seeing as how star party season and warm nights are almost here I decided to spoil myself by getting my first nice eyepiece. Whether I win this one or not I'll eventually be getting one, haha...but for the sake of it wish me luck! I'm sharing this with you all because I don't think my husband or kids really give a Rubbish and I'm pretty excited about this, haha.
  12. I've been hanging onto this mount for a while, but not really bothered using it since I got the NEQ6. thinking of getting a new scope for visual later this year, and will a) need the money and need something bigger than the EQ3-2...so here it is up for sale again. I got it a year and a bit ago from FLO in clearance. It is missing the polar scope cover and doesn't come with any form of dovetail. One of the leg clamps has cracked, but I have secured it with a heavy duty rubber band and it still works fine - I have not had any trouble with it. the legs are filled with sand to aid stability. All the counterweights, accessory tray and slow-motion controls are included. The mount currently has a polar scope fitted and I also have the RA motor installed for long exposure AP - I have managed to push it to over 2 minutes, but that is at the limit. But it is a good mount for getting started with or for widefield photography with a DSLR. It won't get you taking the glorious pictures you see some of the members here coming up with, but it is a cheap way to have a go and see if it is for you or for grab-and-go widefield. It all cost me about £220 so, bearing this in mind, and the damage. Would accept £130 for the whole lot. Collection preferable, but happy to look into postage, although I suspect that will be over £10 easily. Delivery/meeting half-way could be "doable" as well depending on location. Prefer to sell as one lot, but would consider splitting.... tripod and Mount £70 RA Motor £40 Polar Scope £ 25 (again plus postage) While looking for this under the bed I also found a couple of Skywatcher eyepieces (the ones that come free with your scope) - 10mm and 25mm. These seem to be around £6-8 on Astro boot, so would be asking £13 for both including posting, or £6 inc. postage for one. And, finally, I found this Hanhnel BH-40 Ball-Head I used when building a barn-door tracker a while back - don't use it now, so no use to me. It is in great condition and has a screw in adapter on the base to fit thick and thin threads. Think these are about £25 now, so £17 including postage Thanks for looking Mark
  13. Hi All, I've been getting along reasonably well with observing but I find the glasses really annoying having to take them off most of the time. Are there any recommendations for long eye-relief eyepieces suitable for glasses wearers? Thanks, Neil.
  14. Hey guys I know that a 2x barlow decreases the light by 2 squared so 4x. The question is: If I have an 8mm eyepiece and I 2x barlow it, how does it compare to a 4mm eyepiece of the same make, range, etc. Is it also around 4x less light?
  15. Hi. I have got myself an ED80 scope, and have been using the 28mm EP that came with it, but when trying to look at Saturn, it just looks like a bright dot. I would like to see it larger and in more clarity. On doing some hunting around I have read that the Tele Vue Nagler Zoom EP's are regarded as a good quality EP that will last. So the question is, will the 3-6mm EP or the 2-4mm nagler EP's be suitable for my ED80. I got this scope mainly for AP, but I am intersted in visual work as well, so eventually I may get a scope that is a dedicated visual scope, and hopefully the Nagler EP would suit that scope as well. Any advice would be great!
  16. Hi I've been thinking about investing in a better short focal length eyepiece for planetary and other high magnification work. I currently use a 7mm Baader genuine ortho, but this suffers from a couple of issues: first, I can't bring it to focus with my 250PX f/4.7 Dob whilst using my Orion precision centering adapter (which is great, btw); and second, it's got a pretty small apparent field of view which makes for a lot of shoving the Dob around to keep targets in view. Has anybody got any recommendations, or thoughts on ideal focal length? I'd want something that works well with my other 2 scopes as well (6" f/10 Celestron SCT, 4" Skywatcher f/5 achro refractor). Interested in views! thanks
  17. Hi All, I have a 250mm f4.7 Dob and am looking for a quallty eyepiece or eyepieces in the 25mm - 40mm range although I realise that 40mm may be pushing it a bit. Recommendations please, especially from those who have used them with similar scopes. Simon
