  1. Just phoned Telescope House. They took a new one off the shelf and yes its bubble wrap inside. Both 8mm & 6mm are shipped like this. Alan
  2. Can anyone who owns an Ethos 8mm eyepiece please confirm if they come supplied with two pieces of shaped foam inside the televue box (to hold the eyepiece snug & protected) or have televue saved some money by just wrapping them in bubble wrap inside their box? I have E21, E13 & E10 eyepieces and they all come with the white foam inside the televue box. Thanks in advance, Alan
  3. The edge version will cool down quicker as it has vents for cooling. the edge version has mirror locks, useful for imaging with the larger c11 mirror. Just one more thing to fiddle with or ignore for visual. the edge has built in reducer for imaging, not so useful for visual. collimation is the same. fastar is the same. i decided that the same money spent on a larger c11 standard was more worthwhile to me as a visual user than a c925 edge. Aperture wins every time and does make a difference to the visual observer! Or you could go the same size and use the saving for a nice dual speed micro focuser, now that would benefit a visual user! The price of the edge should mean you get a dual speed focuser. The c11 really needs dual speed, my c8 was fine without one. Alan
  4. Double stacking makes a big difference. It cannot be overstated. I would expect a double stacked ls50 to out perform a single stack ls60. Double stack ls60 will outperform a ls80 and so on... it wouldn't surprise me to find a double stack PST to outperform a single stack ls50. It has 45mm aperture I believe? Reduced brightness will always be the downside of double stacking. With the smaller aperture being double stacked then darkening will be an greater issue than with double stacking a larger aperture. Stating the obvious. proms are the first casualty of a darker image.
  5. Yep, double stacking is expensive but there is no going back. The detail is much much better. i have never used my lunt60 in single stack mode apart from a quick look when it was new. The double stack never comes off!
  6. Correctamundo! Why indeed...?? the aperture reduction to 50mm should make the result identical to a ls50 double stack aside from the larger blocking filter that comes with the ls60. when I bought my ls60 double stack from Ian king imaging, he said that he had had complaints of lack of brightness in the image from people who had stacked a 50mm double stack on the front of the ls60. He said no-one had ever complained who had stacked a 60mm double stack on the ls60!! So I went with that and spent the extra. the 60mm double stack ls60 is phenomenal for sure. It should last a lifetime... the only other thing you may need is a "rotator" so you can rotate the ds to find the sweet spot for the conditions. There is a m90 threaded "rotator" readily available the screws on the ls60, don't know if one is available for the smaller ls50? there is a pic of my setup in the solar section, in a thread called "show us your solar equipment". On page 3 or 4. I list all the bits and bobs under the pic. Alan
  7. One 7mm is SOLD to Michael. Only one remaining....
  8. Wanted: Televue Ethos 8mm. Must be in excellent condition with all original Televue end caps, boxes & packaging. Must also include the little screw Willing to pay up to £395 depending on the age & condition of the eyepiece. Thanks, Alan
  9. FOR SALE: Two x Televue Delite 7mm eyepieces (one remaining) Both eyepieces were purchased together from Telescope House and have been used successfully as a bino pair. I have recently moved to a big dob and have decided to change to an Ethos 8mm for the wider FOV (less nudging required!) Both eyepieces are in excellent condition and come complete with all original Televue end caps, boxes, instructions & stickers! (see pictures below) I am happy to sell them as single eyepieces to two different purchasers, they do not have to be sold together. PRICE: £180 each (includes next day Royal Mail special delivery) - payment via bank transfer preferred, but paypal also accepted (please use "gift" or add 3% to cover the fees)
  10. Niall. The LS50C is a compact double-stacking filter made specifically for the LS50THa telescope. The dimensions allow it to screw straight onto the front of the LS50. The LS50FHa is a general double-stacking filter for larger diameter telescope than the LS50THa. The dimensions allow it to screw straight onto the 60mm LS60 I believe. It would be to big for the LS50. Remember that you can double stack a LS60 with either a 50mm or 60mm DS unit. If you look carefully at the online images then you will notice the border (with lunt lettering) around the 50mm central red lens is wider on the white LS50FHa. https://luntsolarsystems.com/product/lunt-ls50fha-solar-filter/ https://luntsolarsystems.com/product/lunt-ls50c-double-stack-filter/ HTH, Alan
  11. Matt, There are two main types of visual filter. UHC and OIII (O3). UHC filters improve nebulous objects that you can see already (to show more). O3 filters help reveal objects that you cannot see at all without them. Golden rule with filters is "you get what you pay for". Cheap filters are not equivalent to expensive filters. UHC is usually the first purchase... As John says, a UHC filter will be useful especially in the next 2-3 months as the milky way swings overhead. M8 and M16 reveal themselves well with a UHC. You will get improved views of M27 & M57 too. If you want to see the Veil nebula then you will need a good O3 filter. I would recommend Astronomik branded filters but the price is also "astronimic"! The skywatcher UHC is a good cheap starting point. Not the best UHC but good value for money. https://www.firstlightoptics.com/uhc-oiii-visual-filters/skywatcher-uhc-filter.html Here is a link to the astronomik http://www.rothervalleyoptics.co.uk/astronomik-uhc-visual-deep-sky-filters.html I had the skywatcher UHC & O3 as my starting filters. The UHC performed well in my C8 SCT scope. The skywatcher O3 was poor (it was too dark and blocked out all the stars spoiling the view completely) and should be avoided in my opinion. Since buying Astronomik , I have had no complaints and have seen some lovely nebulas Alan
  12. Lunt 35 was better than a PST. Lunt 50 will be miles better than a PST Go with Lunt, you will not be dissapointed. If you can stretch to the 600 BF then that will be money worth spending. The 400 has a 4mm exit hole to your eyepiece and the 600 has a 6mm exit hole to the eyepiece. Makes for a brighter view and a wider FOV. I wouldn't buy a PST. Go for an eyepiece around 14-15mm as a nice starting point. The 25mm will not give much magnification.
  13. Hi Sidd, Your budget is very small and you should consider that all mounts supplied in this price range will be weak and wobbly. The heritage 130p has a table top mount for that reason - because it is preferable to a weak & wobbly EQ one Don't be fooled by the pictures of these sexy cheap scopes/mounts - at the end of the day they are cheap mounts and you cannot get something for nothing! Alan
  14. If you are viewing with a 5 yr old then consider a scope with motors and tracking. Then you can centre the object and let the child sit and view , the object will stay in the eyepiece view as long as you need. With a manual scope you will need to keep recentering the object as they drift out of view (as the earth rotates) i would go for an AZ mount as the eyepiece will be at the back of the scope and you can get a stool or similar for the child to sit on. Avoid EQ mounts they are not the best for your scenario. personally, I think you choice of a 6se or 8se is a good one. Don't worry about collimation, SCTs hold it well and it is not a nightmare others will have you believe. https://www.firstlightoptics.com/se-series/celestron-nexstar-6se.html if you go for an SCT then you will need a "dew shield" to keep the front plate from attracting dew. if going second hand then a cpc800 is a great scope and very very stable, no Wobblies to worry about. They go for around 900 second hand. https://www.firstlightoptics.com/cpc-gps-series/celestron-cpc-800-gps-xlt.html Also have a look at a skywatcher star discovery which is also a nice starter scope. https://www.firstlightoptics.com/reflectors/sky-watcher-star-discovery-150p.html All have motors and tracking, very important to make it easy for kids. All allow for you to sit comfortably with the eyepiece at a decent height/angle. have a look at vids of these scopes on YouTube... Alan
  15. If it's similar to a skywatcher O3 then it will be pants! I am not saying you are wrong I would send it back for a refund same as you... i would just add that the skywatcher UHC is not bad for the price ( unlike their O3) if you have one of these then don't sent it to the loft! - there, that's just to be fair to skywatcher as it is Lumicron that are the butt of this thread.
