  1. Now I'm sure that there are already 100's of posts identical to this one, so I apologize in advance for that. Anyway, I use a laser collimator when collimating my SW Explorer 200p and the laser is way off of the centre point of the primary mirror. Because of this I tried to adjust the 3 screws on the secondary mirror, but each time I try to do so, the laser point goes back to the same point and it appears as if it isn't moving. I am applying pressure when trying to adjust the screws, but I don't want to push too hard in case something breaks. My scope has been like this for weeks now, and I don't collimate it often because I only tend to take it into the garden 10ft away. If anybody can give me any suggestions as to what I should do or if I'm doing something wrong (which no doubt I probably am) then I would be very greatful. Thanks.
  2. The 25mm ep I have isn't the stock one, although the 2x Barlow and 10mm are. I hadn't considered using the barlow, but maybe the 15mm bst might be better, as then it would offer 7.5mm too, unlike the 18mm which would offer 9mm which is very close to the 10mm ep I already have.
  3. Thanks Sirius, I have had my eyes on one of these for a while now, especially after all of the positive reviews it gets. Thanks for the reply, I'll get it and hopefully won't regret it. Thanks
  4. I have been thinking about getting a BST starguider 18mm ep it go with my sky watcher explorer 200p newt. My budget is fairly limited, is this the right choice? I already have a 25 and 10mm ep's too.
  5. Yes I've had the mount for a few months now and have the correct setup for it
  6. Thanks Steve, I'll make sure to turn daylight saving to 'Yes', but I am pretty sure that I entered longitude and latitude correctly.
  7. I made sure that the date was in US format, the longitude was 000 10' and latitude was 51 37' with the time zone at 0 and daylight saving was no. The alignment I tried to perform was a 2-star alignment, which is why I was pointing it at Vega.
  8. I bought a Goto upgrade kit for my eq5 skywatcher mount after finally having enough money to do so, and after setting it up and taking it outside I encountered a few problems, and although they are probably being caused by me being unfamiliar and slightly confused, I thought it would be a good idea to share them to be on the safe side. Firstly, after entering what I believe to be the correct longitude, latitude, date & time etc. and asked it to slew to Vega, it pointed at the floor. Then when I tried to use the arrows to manually direct it to the first star, the motor wouldn't let me point the telescope more than about 45 degrees upwards, but it still let me slew it in every other direction. The same thing happened when I tried to align it with the second star. I have no idea what is causing it, is it possible that I have entered incorrect data, or is it broken? Any response would be greatly appreciated. Thank you.
  9. I live in a suburban area which is not completely ruined by light pollution so I can make out a few constellations, along with a couple of planets. I will continue to search for visible DSO's (if there are any), and if I have any success I might think about getting an OIII filter.
  10. Thanks everyone for helping, I am now thinking of opting towards gettign the Baader Neodymium Filter instead, that Mitchelln and CodnorPaul suggested
  11. I recently bought a Skywatcher Explorer 200p and live in London, so light pollution is a big problem, and have began looking into filters and am finding everything rather confusing as I am new to this. I have had my eyes on a Baader OIII filter, as it looks quite suitable and cheap (money is an issue, and I don't really want to be spending more than £75), but I am thinking that further down the line I would like to begin with imaging. Narrowband filters also caught my eye, but all of the different symbols and stuff confused me, and they are ALOT more expensive, so I guess the two questions I am asking are: Is the filter I have suggested good enough? and Should I invest in a narrowband filter, as they look better for imaging (although like I said before, price is a major factor in all of this, so nothing too expensive) Thanks, and this is my first post, so I am sorry if I am repeating what others have said in separate discussions.
