  1. Thanks for advice. Now have dew shield ordered. What would people advise to get rid of existing dew? Bringing scope indoors or just blowing a hairdryer down the tube?
  2. Hello all, I'm very happy with my 10" dob but I have noticed that when looking at Jupiter there is the kind of blooming of the light that you get when looking at headlights through a rainy windscreen and I wondered if it was dew on some part of the telescope and if it is, how I get rid of it. I keep the telescope fully set up on its mount in my garage with an old settee throw over the top of it - might that be causing the issue if that's what it is? Thanks for any advice, Noreik
  3. Thanks for all the advice. I don't have a bad back (yet!) and would be storing the telescope in a cool location most of the time, which should minimise the cooldown time needed, so I'm going for the 10" Skyliner via FLO. Fingers crossed it's here for Friday's (seemingly) clear skies! Thanks again all.
  4. Hello all, I'm trying to decide between an 8" and 10" Dobsonian, for most DSO but also occasional planets. Not worried about astrophotography for the time being and would not be worried about this scope being able to produce pictures of any quality. I was thinking either: http://www.firstlightoptics.com/dobsonians/skywatcher-skyliner-200p-dobsonian.html or http://www.firstlightoptics.com/dobsonians/skywatcher-skyliner-250px-dobsonian.html But if people have recommendations of others, e.g. : http://www.telescopehouse.com/revelation-10-f-5-m-crf-premium-dobsonian-white.html I'm open to suggestions. It might be a question for a separate thread, but what is the difference (apart from the size, obviously!) of 1 1/4" EPs and 2" EPs? Thanks in advance, Noreik
  5. Just been for my nightly exercise in futility...2nd star was in the right section of sky (i.e. I could see what it was trying to do) but still needed significant adjustment as was outside the FOV of the lens, completely defeating the object of the GOTO aspect! After starting again for the 5th time this evening and aligning using 2 star, with the second star being Dubhe and the first being Sirius, I then asked to see Dubhe...the star that I'd just told the mount it was pointing at...and it slewed anti-clockwise about 10 degrees and down about 2! Surely that can't be me being thick?! Anyway, I'm sick of it now so I'm going to ask to change it for an 8" Dobsonian so that the money I spend will actually improve the experience rather than frustrating me.
  6. Update - checked the voltage for the mount, which says 11.4V - is this sufficient? Also, after aligning the handset says something about 'caution previous NP or NL values applied' - does anyone know what this might refer to as it had FLO stumped?!
  7. Hi Popeye, Once it slews round to second star, it is always off - usually azimuth rather than altitude - so after changing the rate of slew up to about 8, I centre to finderscope first, then to 25mm eyepiece and then to 10mm eyepiece and then I press enter. Alignment successful is displayed, followed by something about previous NP values being applied or something similar - I have no idea what this is - and then I test it by pointing at another star and it's miles off, again, usually azimuth rather than altitude. Then I post another message on the forums! Mikea - I think I remember checking the voltage when using the rechargables and it came up as 9.6V as you said, so I will check again with the batteries I'm currently using to confirm that it read 12V. The only other thing I can think of is can anyone in Northampton swap 30 minutes of their time for selection of drinks of their choice? Easy on the methuselahs of Dom Perignon though!
  8. Thanks for the feedback. I'm struggling to get my current scope aligned correctly using the GOTO system as it claims to be aligned and then when I test it to look at another star it doesn't point anywhere near where it should - but my woes are in another thread! I think maybe changing to a Dobsonian might be the best advice because it seems like I wouldn't get a huge amount of change out of £800 with a 130PDS, motor driven mount, CCD and laptop, which is a bit much seeing as I didn't have a telescope at all until 3 weeks ago. The Dobsonian would then let me just enjoy finding my way around rather than getting annoyed because I can't get the GOTO system that I paid extra for working correctly!
  9. Tried again tonight with alkaline batteries (I don't want to pay out for a battery pack if I can't get this working) and tried both methods of aligning but without success. The two-star alignment method was about 45 degrees further east than it should have been when I asked it to slew to Alderbaran to check the alignment, so I don't think the red dot could have caused that. I've double-checked I've got the names of the stars correct on Stellarium before and after going out too. Can anyone suggest anything else? I feel thoroughly disheartened as I can't even align a GOTO scope correctly so actually finding anything worth looking at may well be beyond me
  10. Hello all, I wondered if I could have a little ramble and more experienced stargazers who may have asked themselves the same question when starting out may be able to offer some sage advice! I received a Celestron Powerseeker 114EQ for Christmas, but there was a problem with one of the slow motion controls so it had to go back. It was an unexpected present, but one that really excited me as I have always been interested in astronomy. I found the EQ mount complicated and I was unsure if I had set it up correctly, but have since found numerous youtube clips that would probably help. However, by that point I had ordered a Skywatcher Star Discovery 150P, putting the extra money to it myself. I went for a GOTO mount to avoid having to learn EQ mounts, to be honest, and so that I could tell the scope I wanted to look at Jupiter or Saturn or the Orion Nebula and I'd be there pretty much straight away. Due to inputting the wrong date format and using the wrong batteries, I still haven't got the scope working as it should but I have learned a lot more about the night sky already by learning more of the stars that are used for alignment purposes. I was thinking of sending it back and replacing it with an 8" Dobsonian as my thinking was that if the GOTO wasn't working correctly, I may as well have a larger aperture for the same money. I have found it very beautiful looking at the stars for alignment purposes and got a buzz of success when I located the Orion Nebula without using the GOTO system, but what I actually saw was a little disappointing. While I knew I wouldn't be seeing the glossy photos from the books I've read, I expected a little more. I was still proud of finding it, but if I get the GOTO system working, then that may take away that sense of achievement... So now I'm wondering should I go down the imaging route with a 130 PDS, EQ3-2 mount (with dual axis motor, which I'm guessing is essential for imaging?) and something like a Celestron NexImage CCD - but I don't have a laptop and I'm guessing a 10m cable to my desktop would be a little impractical! It may even be that I don't even get the extra imaging equipment yet, but from what I've read the 130 PDS would allow me to very easily move in that direction whereas the 150P wouldn't as it's on an Alt-Az mount? Any suggestions, advice or feedback would be great! Thanks, Noreik
  11. Hello all and thanks for the kind words. Out again tonight to try using the correct date and straight away I was encouraged to see names of stars come up that I could actually see and were not below or on the horizon. Brightest star again did not seem to work, so I tried 2 star alignment with Betelgeuse and Alioth (as I read somewhere to try and select stars greater than 60 degrees apart for greater accuracy). The scope slewed round to Alioth on the edge of the 25mm lens so made some quick adjustments and thought I was sorted. Asked the scope to view Saiph to check the alignment (I also figured that if it 'knew' where Betelgeuse was then a star in the same constellation should be a doddle) and it was quite a considerable way out as in the width of Orion away from Rigel even. The altitude seemed right, but the Azimuth was what was way off. On the bright side, I did manage to see my first galaxy, the Orion Nebula, by using the direction keys to align...but I sort of wanted Synscan to do that for me 'cause that what I paid for! The only thing I can think of that I'm doing wrong is not polar aligning (but my understanding is that isn't necessary with this sort of mount) and/or I'm using rechargable AA batteries (which I charged two nights ago). I would consider getting a powertank, but not until I have the Synscan system working! Can anyone else suggest anything I'm doing wrong? Thanks in advance, Noreik

  13. Chris - you may have solved it! I'm pretty sure I put in dd/mm/yyyy. In fact, I've just looked at Stellarium for the date I was inadvertently entering and it makes perfect sense for the mount to be telling me to focus on the stars it did. Will try it again the next gap in the clouds and will use the slew keys. Does it matter where the scope starts from? I.e. do I need to point it north and at 0 degrees altitude? Thanks, Noreik

  15. Hello all, I have recently got one of the above telescopes for Christmas and I'm really excited about finally having a proper telescope BUT the Synscan does not seem to be working correctly. If I can just list below the steps I have used: 1. Set up the tripod, using a spirit level to ensure it is level.2. Attach the OTA.3. Turn on system and enter the relevant information - Long first, around 0 degrees West and the Lat, around 52 degrees North; time and date; +0 for time zone and no to daylight saving4. Choose alignment method - at this point, Skyscan usually suggests Altair, Vega or Deneb for Brightest Star Alignment, none of which I am confident in finding (and don't believe the location information on the handset - more about that shortly) so I usually try 2 star alignment. Tonight, I chose Alioth as the first star and then Capella as the second star.5. I manually moved the tube in the right direction (I mention manually just in case this is wrong, but I did also start from 0 altitude and then use the motor subsequent and got similar results) and then centered in scope using the 25mm and then the 10mm eyepieces. 6. I confirmed that Alioth was centered in eyepiece and then the scope slewed to Capella, only it was nowhere near Capella - only 23 degrees of so of altitude whereas it is much higher (Stellarium confirms that Capella is at 82 degrees of altitude at the time of night - 9pmish - that I was looking).7. Not to be disheartened, I used the motor to move Capella into the center of the scope, first with the 25mm and then the 10mm.8. Alignment complete came up.9. It did say something about NLE or NPE, which I'm not sure what it meant.10. I tested the alignment by asking it to find Dubhe and the aligned itself roughly halfway between The Plough and Gemini.11. I started again, this time starting with Capella as the first star and the results were even worse!Is there anything I'm doing wrong?If it isn't me, then I'm thinking I may as well have a larger Dobsonian mount scope or an EQ Refractor at a reduced price (my budget is c.£400). If I do need to return the scope, what would people suggest in place - probably going to be more into visual astronomy that astrophotography?Thanks,Noreik
