  1. Regarding barlows, I have a x2 and x3 but only use them when using the webcam for imaging Jupiter. I can split the double-double in Lyra with my 5mm X-Cel and going any higher in magnification does not seem to be useful as focus is too difficult. My 10mm X-Cel gets a lot of use, second only to my 32mm. So if I had to choose two EPs, it would be these. I suppose if you want to keep EP to the minimum and use barlows: Starting with a very good 32mm on it's own; would become 16mm with x2 barlow; 10mm with x3 barlow; 5mm with x2 plus x3 barlows. I've never tried to do such comparisons though. dag123
  2. Hi Vacuum, I replied to another your posts in another thread on a similar topic. But to respond to the things being discussed here... I don't use the red-dot-finder, rather just manually star hop with my 32mm EP from the EP kit. I chose the EP kit for no other reason than to learn about how the EPs behaved and to find out myself what works well and what does not. The results are quite simple. The 32 is used all the time for locating targets, the moving up to the 13mm. The 8 and 6mm are not really used much, instead I have the two XCels that are much easier to look through. Hope this helps. dag123
  3. Hi Vacuum, I have this scope and have been able to view M82 quite easily given a dark-enough sky with no clouds. I use the 32mm EP from the Celestron EP kit to locate both M81 and M82 in the same field of view - no need to use the red-dot-finder, just align the whole scope roughly at the right point in the sky and in the 32mm FOV it is quite easy to locate, especially if you have used the ocular view in Stelarium so you have an idea of what to expect. If looking at one or the other I'll then switch to the 17mm, although to try and spot the current supernova I have been using the 10mm and 5mm X-Cel EDs, the 10mm probably giving me the most confidence I did actually see it. Hope this helps dag123
  4. Thanks for all the replies so far. I don't think I have heard enough positive comments to get a light pollution filter for now. I am sure when older camping and staying up late will be something to look forward too. dag123
  5. Regarding the dew shield, I have already wrapped my scope with sections cut out of a camping mat. This includes a tube about 30cm long, painted matt black which acts as a light shield. dag123
  6. In fact I did use a sketch to double check, although compared to Moonshane, mine was just a scribble. - even with my light polution it was far to dark to be able to see the pencil marks on my bit of paper as I did my best to draw my EP view. From the view in my EP, I noted a group of four stars in a kind of cross shape below M82 and there were what looked like four stars starting to the left of M82 and going accross it heading to the right. When I went inside and compared with what Stelarium showed, once I had matched the correct rotation with the cross shape of stars as a reference, I had an extra star on my scribble overlayed on where M82 would be. I am hoping this extra star is the supernova. I too understand that the supernova should increase in brightness and so will hopefully confirm what I saw. Certainly when I viewed the SN in M101 a year or so ago I was able to watch it fade to nothing over a few weeks, confirming it was the supernova and not a star. dag123
  7. Thanks for the replies so far. Unfortunately, going somewhere darker is not so easy if you have little ones asleep in the house to watch over. I was looking at the follow filters on the FLO website http://www.firstlightoptics.com/light-pollution-reduction/baader-neodymium-filter.html http://www.firstlightoptics.com/light-pollution-reduction/skywatcher-light-pollution-filter.html The latter at less than £20 is perhaps worth a try, but I am not sure it is worth going for the more expensive option if there is little to gain. dag123
  8. Hello, I had clear skies last night and so ventured outside to try and spot the supernova that has been seen in M82. I was able to find M82 without too much trouble with a 32mm EP but the light pollution made both very faint againt the background glow. When I switched to a 10mm EP I would like to think I managed to spot the supernova with averted vision. Anyway, to my question, I don't have any light pollution filters and so I was wondering if they might help. My road has has orange streetlamps but a more whitish glow seems to be coming up into the sky from the direction of the local shops. Any ideas? Thanks dag123
  9. Well the event last night certainly suffered from the Brian Cox, Stargazing Live effect. The car park was overflowing and it was standing room only during the presentations. A pity the cloudy skies meant most scopes were left in car boots and and the visitors were unable to experience a proper look at the night sky. dag123
  10. I thought these glasses were rather good too, I've just ordered a few for myself and the children, hopefully by the time the glasses arrive we might have some sun! dag123
  11. Hi all, As a member of the Hertford Astronomy Group I thought I would pass on the invitation to the following event. dag123 Happy New Year to you all. The Hertford Astronomy Group is delighted to invite you to our Stargazing Live Event on Wednesday 8th January at the Cricket Club Pavilion, Ascots Lane, Welwyn Garden City.This is our special event to coincide with the BBC Stargazing Live programmes being shown this week on TV.We welcome you all to come along with some friends if you like to share our enthusiasm for this exciting subject. Starting at 7:00 and going on until 10:00 we have presentations throughout the evening covering Space Weather, the Milky Way and other Galaxies and Space Exploration. The event is suitable for all ages from about 8 years old onwards - children must be accompanied at all times by a responsible adult - there will be some delicate instruments around.Refreshments will be on hand and, hopefully the weather will be clear, telescopes to look through to see some of the wonders of the night sky. There are some amazing sights at this time of year from the wonders of the Orion constellation, the beautiful Pleaides star cluster and even distant galaxies!The majestic Jupiter is in a superb position for observation and if you have never seen it before through a telescope then you must come along and see just how it changes from what looks like a bright star to become an object of wonder and delight.We promise you a fantastic evening even if it is cloudy. There will be lots to see and chat about so come along and be a part of the event that will be exciting the country this week.We look forward to seeing you there.Details of this and much more can be found on our website www.hertsastro.org.uk
  12. Hi, For what it is worth my most-used EP is the 32mm that came with my eye-piece kit. I no-longer bother with the red-dot-finder, rather just sight along the length of the scope with the 32mm in place and most often than not I get what I am looking for somewhere in the large-field-of-view. I then centre and add magnification as required. Although I do use my 5mm EP to split the double-double and try and spot those difficult targets in the Trapezium, in most cases I find 10mm gives a clearer, albeit smaller image. dag123
  13. Hi George, I trawed back through some of my posts from a couple of years ago, my first attempts at imaging Jupiter with my Celestron 130EQ and a cheap webcam.. http://stargazerslounge.com/topic/76963-embarrassing-jupiters-webcam-clinic/page-18#entry1238404 http://stargazerslounge.com/topic/76963-embarrassing-jupiters-webcam-clinic/page-17#entry1234420 This whole thread is a very interesting read and you will clearly see what you might get with many different scope. Plus loads of tips for the whole process of setting up the scope to the image processing of the results. Hope this helps dag123
  14. Hi, I have this scope and my experience of observing Jupiter. (following aligning scope with Polaris, switching to a 5mm EP and defocusing to check collomination) For my viewing of Jupiter I use my Celestron X-Cel ED (10mm & 5mm) EPs. As has been suggested the higher magnification is not always better. While I can get a reasonable view of Jupiter with the 5mm I find that it is slightly washed out by the brightness and shimmers a lot more, resulting in less detail being visable even though the disk is larger. If I want to observe the bands in detail I find it far easier with the 10mm as that gives a crisp clear disk, albeit smaller. Hope this helps dag123
  15. Hi, I have had this scope for a couple of years now. I agree that the red-dot-finder is not much use, and so I just don't use it. I have a 32mm eyepiece, from the Celestron EP kit, and with that I just line the whole scope up in the general direction of what I am looking at. The field of view is so large that it is very easy to get your target somewhere in view, then centre it with the controls and then increase the magnification. This method is far quicker than when I was mucking about with the finder and ended up getting cold before I'd even found my first target. Regarding images, I have done rather well (IMHO) with a cheap webcam, jupiter, mars and the moon. For the moon I have also done reasonably well holiding up a camera phone to the EP. The quality is not as high as some of the amazing photos you will see posted here, but for a beginners scope certainly good enough for you to decide if you have the astrophotograhy bug. Hope this helps. dag123
