  1. I would agree about Pembrokeshire as I was staying at my aunts last year who lives in manorbier, the sky was excellent, truly dark sky and no light pollution. I got a brilliant view of the milky way, in fact this was what got me back being interested in astronomy.
  2. Here are my first ever attempts at imaging. These were taken on a 250PDS on dob with a Meade 4000 SWA 40mm lens which I attached a Panasonic GF2. Most of the images are not to bad but toward the end the cloud coverage was starting to cause the images to blur. I also do not have any of the moon at full eclipse as just as it became fully eclipsed a cloud bank rolled across my vision and stayed there for about 45 mins.
  3. I have got the ES 2" 2x focal extender but do not have the TV powermate so cannot compare, but I have found it to be an excellent addition to my collection as it gives nice and sharp images when in use with no apparent lose of light due to more glass and very well built ( but it makes it a little heavy ). I have read that the performance of the ES focal extender is very close to a TV powermate ( the TV is said to be slightly better performing ) but it is a lot cheaper and when I was looking for a barlow / focal extender and wanted one that did not change the eye relief, I could not warrant the extra cost of the TV powermate as it is at least a third more expensive than the ES focal extender and as I had read it was not a third better performing.
  4. Well had my new 16mm lens out last night, did not get much stargazing in because of bad seeing but I did manage to get some views of the Orion nebula ( very good but hazy due to fine cloud ) and got some wonderful views of the moon ( I need a moon filter badly as I nearly went blind ). With this eyepiece the moon was fantastic, bright and detailed and absolutely no signs of CA or any other distortion ( it was even more detailed with my Tele extender ) and once I had got used to the eye positioning there was no problem with blackouts and I could see very well to the edge of the image. If this eyepiece works just as well when I get a good night viewing of the stars ( and a few galaxy's plus nebula's ) I will be buying the 7mm version as well. I will report back again when I get some more viewing in with this eyepiece.
  5. That is exactly the same thought I had concerning the focal lengths ( and the 18mm was to far away from the 11mm and to close to my 40mm on a focal extender ). I will do a small review when I get some viewing time in on the eyepiece. P.S. This will probably be posted in my thread in the eyepiece section.
  6. It is quite a nice little package at the price it is at, and it is supposed to be sealed and gas purged to stop condensation in this new design but still using the original optics. In fact if this one works out ok I will probably buy the 7mm one as well. The only thing I wish was that one was made with a focal length of around 10 - 11mm, as it stands that length will probably end up being occupied by a Explore Scientific eyepiece.
  7. Well I finally got around to ordering the first of the eyepieces that I wanted, a Nirvana-ES 16mm UWA. Quite nice looking and very light, had look though it on the scope during the day, nice and clear views ( apart from the murky sky and the moment I got concerned that I could not get the eyepiece to focus with the focal extender on it ( forgot to put the 2" spacer back on )) and I managed to get 10 minutes viewing in tonight and was quite impressed with what I could see. When I do get to put some serious viewing in with this eyepiece I will try to do a proper review.
  8. The first of my wide angle eyepiece collection.
  9. Well had this out tonight for its first proper use thanks to a neighbour who lent me some short focal length plossel lenses and all I can say is wow, we hit the pleiades then Andromeda then the north American nebula ( which was not to good thanks to poor seeing ) and mars, then the moon which even with some cloud was fantastic.
  10. Hi I was wondering if someone could give a little advice on choosing some eyepieces for my new scope ( 250 PDS on a dob ). At the moment all I have got eyepiece wise is the stock 28mm LET which comes with the scope ( not impressed with ), a Meade 40mm SWA ( japan ) ( gives lovely clear images ) and a explore scientific 2" 2x focal extender, what advice I need is on some shorter focal length eyepieces. I will be using this scope for a mixture of looking at planets and DSO. I have been looking around and a couple of eyepieces have caught my eye, SW Nirvana-ES 16mm and 7mm eyepieces, I was wondering if anybody has any opinions or experience on these lenses particularly on a 10" F4.7 scope, another range of eyepieces was the BST Starguider lenses but with these lenses being only 60 degree will require more nudging of the dob to stay on target plus I have read that these lenses are a bit marginal on a fast scope, again I would like any advice on these lenses would be helpful as they might be useful for looking at the moon and planets. I would like the explore scientific 82 degree lenses but most of them are a little out of my price range ( I might look at the Opticstar 82 degree range ). If I stayed at 82 degree lenses I was thinking of eventually ending up with this range of lenses ( but it might take a year or so ) 40mm Meade SWA ( 68 degree ) 28mm Nirvana 82 Degree or ES or Opticstar 24mm 82 degree 16mm Nirvana-ES 11mm ES or Opticstar 82 Degree 7mm Nirvana-ES 4mm Nirvana-ES plus a ES 2" 2x focal extender Any thoughts on this line up or any other recommendations would be appreciated. Thanks in advance. Karl.
  11. Hi after wanting a scope for over thirty years I finally got around to buying one ( a second hand 250 PDS ) and as I am at the moment only going to using it for visual use I thought that a dob mount would do the job. With this in mind I did lots of research and then designed my dob stand to suit my scope, the dob was mainly constructed of chipboard, laminate worktop and hardwood I had laying around left after other DIY projects from around the house. I also machined up some nylon bearings to run on the laminate surfaces of the altitude and azimuth bearings ( this is quite smooth but it needs a little lubrication with some Teflon spay every now and again ) and to make moving it around a little easy I fixed some braked casters to the base, The dob was also sprayed with some paint I had left over from spaying my car. There are some further mods I will be making in future such as making the dob easy to take apart so I can get it in the back of a car and I fully intend to make and fit a DIY digital turning circle setup which will be paired to sky safari on my tablet at a later date, but first I want to get some viewing in as it stands.
