Hi guys and girls, i am completely new to astronomy and could do with some advice on what would be best to get for my first scope.

What do you think of this scope: http://www.bristolcameras.co.uk/p-sky-watcher-star-discovery-150p-computerised-go-to-reflector.htm#accessory

Seems to be good value for the money, but i honestly dont know what i'm really looking at?!

give me your opinions and any reccomendations on brands and specific scopes, this would be great thank you!

Hello and welcome,it would be good to know what your main interest is,ie visual bit if photography,what your really paying for is the electronics,personally i would go for a Skywatcher Skyliner 200P Dobsonian 8" dob,and just learn your way around the sky,you would have money left over for maybe a couple of eyepieces like the BST,s.

General suggestion (although here it's really a matter of taste/philosophy): it depends on how much time and effort you want to invest before gettings results. If you never looked at the sky before, a good monocular or a binocular are just fine to start with. If you just don't know, then I'd advise as a first scope one with at least goto and tracking: this really brings you right away to see things and relax with the tracking, giving istant gratification. After that, you can better judge whether you want to go the "pure" (no motor) way, or go on with the "comfort zone". In fact, in terms of learning the sky, I found I learnt much more from a motorized scope when a beginner, so that now I can just point without go-to: the other way around is way harder, and can be a stopover for a beginner.

Of course just my 2 cents: other people are really passionate about this and would surely advise the "pure" way, no motors no tablets etc. I think it is very personal: in retrospect, I found my passion and ability grew quickly and fast just because of the motorized approach, starting right away to spend hours and hours looking at things and learning the sky since day 1 (I still remember fondly my first two nights with a (motorized) scope, each up until 3am, and discovering the second day I had missed the real first accessory of any scope: a good adjustable chair (nothing like realizing it's 3 am again because of your back sore ;-) !

Either way you go, have fun!

this is a good telescope at a reasonable price, It's on an AltAz mount, so you won't have the woes of an EQ (personal opinion) and it has freedom find, so you don't need to rely on the computer and your can have a go at finding things manually with the fall back of asking it to do it for you when you get lost and frustrated.

as Paul mentioned though, you do pay a bit more for the mount, the same scope on a dobsonian mount (fully manual) would be about £150 cheaper.

The Sky Discovery you are considering looks very interesting for a beginner mainly interested in visual observing. I know a couple of people who have them and they are very happy. You might watch this video:

Note that the presenter mentions three areas of potential concern. You'll get better results with better eyepieces - but this is common for most less expensive telescopes (and at the top end they don't usually give you an eyepiece at all :hmh:). There is limited adjustment for collimating (aligning) the primary mirror - so, either a nightmare or a dream come true (but as said, I haven't heard complaints). The incompatibility of the cable to connect to a computer is actually quite common - Skywatcher isn't the only manufacturer which apparently hasn't seen modern interfaces!

A nice feature is the ability to remove the telescope and use the mount to track a camera. Other than that, however, attaching a camera to the telescope is likely to exceed the mount's weight capacity. I've seen some astrophotographs taken with this - perhaps fun to experiment with but certainly not stellar quality (maybe others have obtained better results?).

I would say it's an attractive option, and certainly in the right direction. A simpler manual Dobsonian would give you the option of more aperture - 8 inches as opposed to six, together with change to buy a better eyepiece. But go-to is a great feature - depending on your outlook. Starting manually may force you to learn the night sky quicker - but go-to will show you a lot more fascinating objects a lot faster!

It's rare that a goto telescope can be used manually I think, if you run out of juice on that one you are not stuck as you'll see in the video. There are several members now using this mount so a search should throw up lots of results.

I have this scope and must say it is a great for beginners and experienced alike. 

Take on board what others say about a dobsonion will get you more bang for your buck which is very true however it depends on what you want to see-if you are happy with just the moon, planets and the more brighter galaxy's then this will get you all that easily. You will also also need to remember that with a Dob you will need to learn all the skills of star hoping to find your targets so you should expect (with the exception on obvious targets) a period of frustration at not finding anything before getting the hang of it where as with this scope it really is a pint and go ( although you will need to know a couple of stars but that is easy enough to learn.

I have both the discovery and a 8" dob and I honestly think that if I had to pick one to choose it would be the discovery.

Thank you for the great responses eveyone, definatly going to go for either the discovery or dobsonion. Guess i just have to make a decision, completely torn!

Good luck! Either will be a good choice. Remember about portability though-a dob is much bigger and bulkier.

hi, so a for taking in my car and setting up elsewhere if i wanted which would be best?

can the discovery be plugged into a mains instead of batterys?

thanks

Depends on your car! A do generally can be fitted in most cars across the back seat but there is no doubt the the SW is allot more portable. If you give me till tomorrow I can send you a couple pictures of them side by side so you get a better idea.

As for power then it can run of battery's however a portable battery pack is recommended (recommend one from maplin as opposed to the SW one)

You can run it from a 12v power supply connected to the mains. Make sure it's a regulated supply, has the right rating (2 amps), the right connector and the right polarity. You are supposed to use one rated for outside use and freezing temperatures, BTW, and a proper one costs about £28. Actually, since you will almost certainly need a battery pack (or a 7AH lead-acid battery) for portable use anyway, you might as well just use that and recharge it every week or two. Fewer wires to trip over.

Yes - smashing images especially with a bike in the background - gives newbies a really good idea of the size of these scopes. Nice one Popeye! :)

      Hello
      I have been away from this forum from possibly July - I never find a lot of time to do anything these days, same to be able to relax reading and interacting Astronomy forums.
      I asked here a few ideas about making a solar scope or modifying whatever I had and I was recommended to also see Solar Chat Forums and I did.
      Thanks to solarchatforums I have been able to do something decent and here is what I have done so far - very slowly!
      1. I purchased a second hand PST and replaced its ITF with Maier one from the US and it finally had a clear image coming through + moved Etalon screw to third position - all the usual thing everybody does [after I researched it]!
      2. used a new SCT screw-on short focuser [used once or twice on a LX200 R Classic] and using Teflon tape I screwed the PST Etalon to the focuser and purchased a 2" adaptor to fit on Etalon.
      3. then used a Chinese 2" to 1.25 and modified the 2" side socket taking internal ring off and making 3x 120° threaded holes and 3x nylon thumb screws and used that as an adaptor to fit the original PST eyepiece holder - strangely enough at present this adaptor is also used as a tilter ... until I buy a proper camera tilter
      4. then fit the above eyepiece holder into the SCT focuser with 2" to 1.252 adaptor in it and screwed the whole Gold PST tube with Etalon in it and made a BETTER PST - see image

      5. I also initially tried a 2.2x DSLR camera Lens magnifier in front of PST and it decently works too - so PST will be fine for full solar disk mainly and without the 0.5 angstrom - not forcibly needed, I am probably around 0.7 as it is!
      6. more importantly, I decided to make my own 90mm solar scope using the above bits and pieces.
      7. with the help of Solar Chat Forums [great guys with a lot of knowledge, some are professional - i.e. they know the optics mathematical details - which helps] I purchased a cheap Bresser AR90/900
      8. the ONLY usable thing there ... is the main tube, a nice and thick tube - the rest is ALL plastic!!!
      I dismounted all parts and saw tube shorter ... a bit too much ! - I could have saved ~6cm really as I went with original ideas, but forgot I was using a different telescope from my initial thoughts - silly me!
      So, I added a 6cm extension - no problems there to reach the 20cm inward needed for the PST Etalon which has ~20cm FL
      9. initially I used a Tuna Fish 100g tin to adapt the SCT focuser onto my AR152 and fit Etalon inside the focuser to get near the 20cm needed- lets call it Quark unit - which it is really!
      It worked well, so I decided to add a second focuser to tune the Etalon ... getting back to AR90/900 ...
      10. I was trying to avoid overspending, I could not afford to spend too much - then I remembered I had a unused AR102SX which in my mind I guessed ... the focuser should over AR90/900 and it did!
      It just fits perfectly - then drilled three holes for the holding screws et-voila'
      11. I purchased a second hand 75mn Baader D-ERF and fit it INSIDE the AR90 tube at about 20cm inside from the front air-spaced doublet lenses, as there are the usual internal rings soldered in and just sit on it and I have about 70mm aperture  - i.e 70mm width from the D-ERF for photons to get through.
      At that ~20cm distance from front lenses the beam is still very large - probably about 60-65mm - there is no heat in between - no need for air-escaping holes
      12. when I have the time I will make a solar finder scope and fit it on the tube - not that is really needed - I usually use CDC to get there almost over The Sun [having an almost exact spot on the yard!] - then use my eye without eyepiece and look thourgh the PST eyepiece holder for solar shinging and centre the telescope over The Sun.
      Well, it works well after tuning Etalon focuser correctly and then focusing/tuning Etalon etc. - the usual.
      See some images - still learning imaging/processing and a lot more to learn about Solar ... a lot!
      I will probably need to get a Power-mate 2.5x when I can afford it!
       
       

      1st mod - without the original black box - it works so much better - better focusing and sharper viewing too.


      This is the AR90/900 shorten tube with AR102SX focuser and adaptors to test it normally
       

       
      This is complete with the Quark Unit on the right side
      Since this image there have been some changing - do not use the revelation adaptor any more and added a 6cm 2" extension.
       
      Here are some images:

      Just thought I would say hi to everyone. 
      I am a Noob, but have been googling astronomy for past year, so am familiar with some of the lighter terminology.  
      Most of my googles have directed me to this site, so I have already read forum posts here numerous times.
      Have already acquired quite a bit of kit, but just not found the time to try it out yet. 
      This should hopefully change soon as I am expecting to have a lot more spare time in a couple of months. 
      Being in the Midlands in the UK, I am not currently missing much, due to the current cloudy weather here. 
      I am looking forward to picking your brains and in time posting some of my experiences here. 
      Kindest regards, 
      Geo.

      I've been considering a short focal length frac to get solar full disk images for a while now and when one came up on ABS the other week I took the plunge and picked up a Bresser AR102xs. It's focal length meant that I could potentially get a solar full disk with my ASI178 in one frame, great for grabbing a disk quick when the weather's not so great (when isn't it). I've also got half an eye on an upgrade to my H Alpha setup which might include a Quark bolted to a short focus frac, so this fits the bill again.
      I managed a quick and dirty first light the day after I collected it but didn't really draw any conclusions due to the rushed nature of the session. Today I had a longer session and managed to explore both white light and Ca-K with this scope. After that initial look with the scope I did not think I could get focus with the Herschel wedge but I managed fine today! It is kind of tough to judge the results with no detail to be seen though.

      The Ca-k is more worrying to be honest, the concern with Ca-K is spherical aberration which limits sharpness in the final image and results here don't look great to me. The advantage of doing a full disk in one shot is that I can combine surface and prom layers like this.

       

      Not sure if I am just expecting too much from the little scope after being spoilt by my Evostar 120 for so long, or whether there is actually an issue. Jury's out until I get a session in with a nice AR to look at and in the meatime I wil try some night-time wide field viewing.

      Can I fit a camera to aSkywatcher 130. 
    • By Floyd1995
      Hey guys. After many years of waiting, I've decided to finally go for my first telescope. Yet, today find myself stuck between two excellent entry-level options, so I'm looking for some help.
      Before I get straight to my questions, I'd like to share some information about what I'm expecting to do with the equipment (among other stuff). 
      - Objectives: Deep Sky, and some planetary observation. No interest in astrophotography, GoTo, or any other device (maybe/eventually in the future). 
      - Budget: Given complementary I'll be getting a 2x Barlow (SkyWatcher; achromatic), and a starguider laser collimator (1.25-2), these are my two best available options to fit on its range.
      - Light pollution: Low-Med. 
      Being that said, here are my questions:
      - Mount: After days of heavy research, so far hardly found a review about it; What do you guys think about the AZEQ AVANT type of mount?; Could it beat Dobsonians?; Would it be a better option in my case? and if so, why?
      - Conventional Tube vs Heritage's Compact Flex Tube: What are the differences (pros-cons) I can expect from one and the other? (despite no difference between mirrors and diameter).
      - Explorer 130P AZEQ AVANT (newbie question): Would it be possible to transport the whole structure armed from one spot to the other in my yard? 
      Any help/opinion welcomed. 
      Happy 2019!
