  1. My brain is the same - I can read or be told how to do something...but it doesn't 'click' until I actually physically start doing it and trying to put into practice what I've been soaking up.
  2. Spot on. Magnification is OTA focal length divided by eyepiece focal length...regardless of aperture. need aperture to be able to get detail when magnified. Usually they say that max mag is 2x aperture in mm. So if you have 150mm aperture, max mag is 300x. Hope this helps.
  3. What about firmware engineering? Glad I'm not the only one that doesn't look at instructions. I do occasionally regret it later...but usually I know better, and say things like "what could the instructions possibly tell me?" Seriously though, just check it over when it arrives and take your time to understand it. You'll have loads of time anyway...there's a rule about the weather being terrible when you get new kit!
  4. As an engineer I did the typical thing and threw the instructions to the side and started twiddling knobs (the scope was a gift that I wasn't expecting and I had no experience with reflectors). I would advise against this, follow the advice above, look at it before you touch anything!! meant I had to learn how to fix it straight away, so I suppose you could say it was like jumping in at the deep end.
  5. Change of plan....again! After a lot of research and pondering (I think my family are sick of hearing about telescopes) I've come up with a plan. I found an AZ4 mount going second hand for around £100 so I nabbed that. Been looking at this for a while and just decided that a goto isn't what I want for now. I managed to get out last night for a couple of hours so decided to play with 2x Barlow and existing eyepieces to see what FOV would be like if I got a mak (currently have 700mm focal length, making would be 1500mm - I understand it's not exactly, but I was just looking for a feel). I found it really difficult to locate things (I can see why people use goto) so I've decided a mak isn't for me just now. Got some lovely views of Jupiter with current newt and actually really enjoyed just scanning about with the 25mm eyepiece. Managed to locate M44 (really beautiful). So now I've decided that my current newt will do for planet and lunar viewing in the city until I have space for a dob. The new mount should make a big difference as the current mount is a bit wobbly. Ideally I now want something a bit more rugged that can get thrown in the car and go away camping with me. I think it would make more sense to have a wider fov to take advantage of the darker skies while being away from the central belt. So I've decided to go for a startravel 102 (was gonna go for the ST80, but figured the bigger aperture was worth the extra weight). I know this won't give me very good views of the planets, but I can see the from the city and use my current scope for now. I think the st102 will be perfect for chucking in the car and taking up north for some beautiful wide field views. I may still consider the 150p at a later date, but for now I'm going to stick with my little 76/700 newt for planets and the moon. Might just hold out for a year or 2 and get a dob. I know this is totally different from the original advice that I asked for, but after some contemplation I think it's a pretty good balance for me just now. I want to thank you all for your advice...and patience with me being indecisive and changing my mind! Many thanks, Davy
  6. Nice one popeye. I managed to finally get my first session of the year last night! Jupiter was looking amazing (between gaps in the clouds) and I managed to make out a couple of bands after looking for a few minutes. I've probably only seen Jupiter about a dozen times, but I don't think I'll ever get bored of gazing at him.
  7. I bought one of these a couple of years ago and it's been pretty useful:
  8. Dom - for what it's worth, I usually collimate mine with a Cheshire during the day when it's light . Then when I take it out at night I do a quick star test. Whether or not this is a good way to do it, I don't know...but it works for me (I've not tried collimating outside at night yet). Photons hit my eyeballs and I see shiny things, so I'm happy
  9. Thanks for that John - makes sense to me now. Thought I was being clever just buying a Cheshire..."It's just something with a wee hole in the top, surely I can use it instead of a collimation cap?!" Just trying to cut corners More toys to buy!
  10. Hi John, Sorry for the silly question - but can you use the Cheshire to align the secondary as well? If so, is there a reason that a collimation cap is better/easier for secondary alignment? Cheers, Davy
  11. Hi Scott I've got 3 X-cel LX eyepieces just now (5, 9 and 25mm) and think they are fantastic - they're probably overkill for my current scope, but they were bought so that I had decent eyepieces when I upgrade my save me having to spend as much money at once! The 9 and 25 get the most use for me (77.7x and 28x for me). I think the 5mm is at the limit for my current scope (76/700 so my max mag should be 152x and the 5mm gives me 140x) so I can't really comment on it as it doesn't get a lot of use (again it was bought in preparation for next scope). I had to send my first 5mm back as there was some speckles and lines when I looked through it - think someone had maybe rubbed the lens before I got it. I've read some people saying that the quality control for the X-cels can be a bit....relaxed. But that may have been talking about the old versions (I didn't realise the LX was a new variant). I paid around £65 for mine, so I would jump at the chance of one at £32. Personally I would go for the 7mm...I actually kind of wish I had that rather than the 5mm. Hope this helps. Davy
  12. Apparently the porta II can take 6.8kg load (according to FLO website). I'm sure I read the AZ4 is around 6kg load? I guess it depends how generous they're being with their figures. Unfortunately the porta II is out of my price range for just now anyway.
  13. To be honest, I think I'll end up with an AZ4 in my collection regardless of whether I end up with the 150p or the 127 mak. I also like the freedom of an alt/az so I can see it getting a lot of use. That's a very good point you make - the stars and planets will always be there for us to enjoy. Just patience isn't quite as limitless as the sky Many thanks, Davy
  14. Hi William, welcome! I'm also a newbie. I have been bugging the good people on SGL already trying to work out what to buy. I've also lost hours reading through other peoples posts and experiences. Cheers, Davy
  15. Would be good if there was some more information about the Skywatcher AZ5. I had a google today but didn't really find anything :-(
