  1. Haha! Yep that did throw me for a loop! right got you, I have that clear in my head - something important learnt today
  2. Mattscar & Moonshane, good points from you both in additions to Stu's, thanks! I am happy now, after feeling deflated before. Thanks so much for your informative replies, its much appreciated. I shall be sure to ask questions re this if anything else stumps me Best Dan
  3. Hi Stu, Thank you! I am glad I had this wrong. So with the SLT127 i would need about an 8mm Plossl or similar to take it to around 187X? And if i went with an SLT 102, at 660mm FL would need a 4mm eyepiece for 165X. Is that about right? Cheers!
  4. Hi there, Im looking to buy a budget scope, like the Celestron 127slt, thats the kind of size and budget i have at the moment. Re viewing planets through the eyepiece - I have read that Saturn is pin [removed word] on most scopes under 8'' so i take it that it cannot be magnified enough to see a decent view of it, even with more powerful eyepieces? So my confusion is also seeing beginners guides stating that you can see Saturn and its rings on a good with budget gear - how, if its too small to see? I looked up two astronomy calculators which show the image possible against what telescope yo
  5. Beautiful shot Ben! Really sharp and contrasty.
  6. Guys, many many thanks for you kind replies, I am taking this all in. I shall indeed buy the book! 1) So, when it comes to focal length, if I had an F5, I can then use a lense to increase the focal length and be able to do planets and DSOs. 2) But, if I plumb for a longer F length like the Evostar 90 or 102 , can a lense be used to reduce focal length to see DSOs - and if so, is it a desirable way to go? I will then need to think of the mount - something halfway ok for a beginners that can have motors added, EQ 3-2 would seem minimum, then later I can upgrade.
  7. Thanks Rowan, the bigger refractor scope you linked to is F5, which I read is not too good for planetary as it is more rich field, so much wider an image? I guess for my first scope planetary is the prority but if you know that an F5 can do that well to that is great. I wish to study the moon as close as possible over a length of time. Grant, thanks, so if a scope is goto and motor driven only, it will not track an object well enough for AP but ok for visual observing?
  8. Hi there, I have some question and hope you can help me. I am just starting out, and firstly want to get something modest to use and then if I really love it to upgrade. I only have around £200-300 for a first scope. My main urge at present is to view planets and hopefully one or two brighter DSOs. I would also like to be able to progress to modest AP, planets etc. So, from what I have read so far, I am drawn to refractors or hybrids, mainly due to less maintenance and the sharpness of refractors. Would starting with a simple refractor like an Evostar 90 on an alt-az mount be a decent start
