  1. Yup - if you're near a power supply with the scope then a plug in 12v dc power adaptor is great. I usually do my observing in a field in the middle of nowhere but 360 degree views lol - so a field pack is more my norm. (You'll get a power cable that plugs into the scope included - but the other end goes into the power adaptor socket which you'll need to get separately).
  2. The first accessory required will be a 12V DC power supply with a ciggy socket adaptor. You can get these as a (circa) 17ah flash light battery pack available in hardware and motorbike parts stores, or a straight leisure battery from caravan and camping stores with many more amp hours (eg 85ah or 110ah). Your average Duracel type batteries run out real quick when you're outside in the cold overnight with a scope. Apart from that it's best to start with the supplied eyepieces and learn how to use the scope before going for extra eyepieces and barlows etc. Learning how to operate the scope is quite straightforward and quick - but it's learning the sky and how/where to find stuff that takes the time - the goto will be a big aid there but you still need to know what you want to see first. You also need to learn how to judge the "seeing" (i.e. viewing conditions). On a moist night a dew shield might be useful. Moon and planets will give good views in the 130P, you'll also see all of the brighter dso's like nebulae (e.g. M42), star clusters (open and globular) e.g Beehive and M13, and galaxies like Andromeda, M81/M82 etc. Binocs are often a good aid to finding stuff for a beginner, even if used just to confirm the scope is pointing in the right direction. Hope that helps and good luck to you and your friend.
  3. I have had both the telescope and mount in your link and they are both ideal for any beginner. My only reservation is that it's a bit expensive on Amazon and these scopes are much better purchased from a specialist astronomy retailer where you get better back up and support. Here's the same scope/mount around fifty quid cheaper and from a very reliable supplier: https://www.firstlightoptics.com/az-goto/skywatcher-explorer-130p-synscan-az-goto.html Hth
  4. I was way out but glad you got it sorted. Been looking at the Swift today and it's a very nice looking little scope. Congrats from me too.
  5. It is quite clear tonight in my area but transparency is around 60%. If you also have some high level hazy cloud it could easily cause the effect you describe. A thin film of dust on the mirror doesn't usually detract from the views. Depends how many nights you've spent out under the stars - the more you do the easier it becomes how to judge the "seeing". But I wouldn't blame the scope at this point.
  6. To check if your scope needs colimation - this article tells you what to test and how to determine from "airy disks" if colimation is required: http://www.backyardastronomy.com/Backyard_Astronomy/Downloads_files/Appendix A-Testing.pdf Hth
  7. Well - I don't see the need for deliberate social dysfunction - but I'll certainly give you full marks for honesty. I'm out of this thread and wish you good luck.
  8. Just a friendly thought - have you ever considered what effect this sort of statement has on other people? Does it make them think you're friendly, like you, and want to help you? Or does it irritate them and make them think you're arrogant/bragging, dislike you, and not want to help you? If you have trouble working out the answer, then there may have been a slight error in your IQ measurement.
  9. You're welcome! Last time I saw the sun in that amount of detail it was through a double stacked TV scope with TV binoviewers and Ethos 13mm eyepieces - about twenty grands worth of gear. So the Quark's doing a great job.
  10. Wow! That's very detailed - impressive stuff.
  11. At least it gave them an idea of what an orrery is and what it's to do with. They'll thank you for that later in life when they come across it and they're old enough to take a more constructive interest.
  12. Just out of interest - which software will you be using for deep sky?
  13. Don't forget that's a "projection adaptor" for plossl eyepieces. Most deep sky astro photography is done at prime focus - so unless you specifically wanted that item, it might not work as you expect. Let us know how you get on with it.
  14. Ahh - ok that's a good mount so I don't think you need worry about it. For an imaging scope you want something with fast focal ratio (around f-5) - for fast subs, and good glass - well figured to avoid chromatic abberation. A good doublet like an ED80 is a great starter imaging scope which focuses two colours - a triplet on the other hand focuses three colours at the same focal point (but usually twice the price). Beware the larger aperture you use the better the glass has to be (and the more $$'s you'll need). You'll also want a guide scope and reasonably sensitive camera to go with it - the ST80 is a popular choice with either a Lodestar or QHY5 guide cam - many folks use a combination of these. Hope that helps.
  15. Which mount do you have Tareq?
