  1. my starting point was the tals own instruction manual...some interesting translations in there I can tell you, but I understand the principles. when looking down the focuser the secondary should appear round and be central to the walls of the focuser tube..the primary should be central in the secondary s reflection...check...done all of this and in gradual steps.. but the image seen at high magnification is still a long way off sharp.. using the collimator I have laser spotted the centre of the primary by adjusting the secondary screws..check...then have adjusted the primary via the screws to find the centre of the target on the laser collimator..that's achievable.....how ever...when this is done the reflection of the secondary and the spiders veins are no longer central when looking down the focuser tube...the secondary appears a long way off centre..??? go figure??? this is my dilemma! i have considered the secondary and how its positioned under the focuser...have done very gradual adjustment there...I have also considered the primary and how far advanced up the tube it is towards the secondary...I understand the principle of focal length...but the adjustment screws at the back of the primary are so short that there isnt that much length to adversely affect the focal length of the telescope...or paerhaps this may be the case...?????? Guessing I am tired at this time of night...I will have another crack at it in the morning with a fresh approach............ thankyou for you imput :-) appreciated...as are any of thoughts from contributers :-) David
  2. Oh my...where to begin? looking for advice really. Last year I purchased an inexpensive second hand TAL-1 reflector..purchase online..came via Currier in working condition if a little bit dirty...but no bother.. it worked :-) On odd nights since last December when it arrived I have dragged it out into the back garden and loved every minute pointing it around the skies...its been like a return to younger days. okay..thats the romance out of the way. Last week I decided to give the whole telescope a deep clean..the mirrors were well dusty so I found the resolve to have a crack at cleaning them..looked at astrobabies web site and her tutorial..the job looked within my grasp so I went for it...had the OTA apart..cleaned the mirrors..gave the whole thing light lube and spit and polish...it was all going brilliantly...then I tried putting the thing back together again...went well...went through my notes about collimating..followed them to the letter..............A week later I am still playing around with this Russian nightmare!! why oh why oh why oh why did I start down this road to hell??? While you can get the telescope to within reasonable focus at lower magnification the sharp images at high magnification that I got previously are unattainable.....so today ( monday) I decided to throw money and technology at the blumming thing...yes!! a laser collimator would solve the problem..that's what's missing here!!..so off I toddled to Rothervalley optics purchased a Sky watcher model and brought it home and set about righting my bad deeds with the TAL......4 hours Ive been here faffing around with this monstrosity!!..Ive followed the instructions to the letter...christ..the end result is worse than if you attempt to align it by line of sight!! Tonight Ive just managed to stop short of pulling the whisky bottle out..getting hammered..calling the telescope rude names in the shed before sleeping off my booze induced coma out in the passageway with the dog!! Why oh why is something that should be so easy so ridiculously complicated!!!!!!!!!!!!!!!!!!!! ( now sobbing uncontrolled ) please someone help!...I promise never to do this again! I just want my telescope back to how it was and be able to look at the moon again....I feel it must be something simple that I am over looking...but its gonna have to be pointed out to me...and I am not one for admitting defeat usually...but on this occasion...I AM!!!! Standard Tal-1, not the motor driven version.. made in 1996...it has a 1.25 inch focuser and EP'S..... davsim66@googlemail.com with best regards David p.s have posted this in eastmidlands section as well as that is where I live.

  4. Yes I will have a look nicnak....one thing I did find out..there are only two shipments of tal pet year...there is no confirmed date when next one is...don't know if other stores are in same boat..may be some time before I get the scope I would like....never mind, back to the binoculars....
  5. My first experience at a retailers has been something of a let down..really was disappointed at lack of customer service... Not impressed at all... Will do My shopping online from now on.....
  6. P.S......looks like you have a bit of a TAL fetish going on the andy...... :-)
  7. with out question the 150p looks like an astounding bit of kit...but the scant amount of pictures on the web of objects imaged through it suggest its a viewing scope not a photography scope..which is fine...not talking myself out of it..havent found one picture of the moon taken through a tal..and that cant be that hard.....its design must be a few decades old...but that is also part of the attraction....yep..my head is a mess!! LOL...thanks for the link to the german site...they have some really nice pictures there of the 150p...have seen it before...when you see the range of scopes that TAL make and the number that uk suppliers stock its seems a great pity that more are not readily available..most of the online suppliers will get you a 150p but it appears its a special order...perhaps the margins they make on the russian scopes is not as great as the far eastern ones??.....
  8. One of the reasons why I keep looking at the 200p dob is because of the 1.25" 2" fittings on the focuser..and its ability to take a t-piece for what ever dslr you own..in my case a pentax kx which is k mount...you dont see much video of photographs being taken using the Tal 150p..and the reviews vary..some say that the tals use unconvential fittings for focuser and ep's...others say the the Tal is supplied with an older type pentax screw fit ring for using with older pentax slr cameras...now dont get me wrong...not looking to do deep space photography here...havent got loads of money...as I suggested at the begining of this thread..my main target is the moon...perhaps have a pop at the gas giants...I know there are limits with a DOB or the TAL..its just not knowing what is compatible with the TAL thats the problem.....somewhere on SGL there is supposed to be a TAL reflector/user group...cant find it...any ideas any one?
  9. thanks for the mini review of the tal-150p nick...perhaps you should publish one in the relevent section of this web site???
  10. TAL? DOB? TAL? DOB?....one thing I do know....I have enough computers in my life that I struggle with already with out the inclusion of another one on a telescope! damn you technology!....decided...going to travel to my local emporium tomorrow and get my hands on a few sexy OTA's...feel even greater levels of confusion on the horizon!
  11. Can you tell me nicnak, what has your experience been with the TAL 150p? And what is the scope capable of? Not actually found an in depth review of it on the Internet yet......
  12. He has documented the condition of the OTA so well..showing the scratch on the body...then when asked about the optics he begins to err....show us the scratch man if it isnt that bad!!
  13. To be honest I don't think I will bid Astro B, would probably struggle to get the thing in the car, the guy selling seems to be struggling to describe the scopes lens condition, and deep down I would like a reflector. Still considering, but in no hurry, I like to do as much home work as possible before parting with the lolly....I am going to see what price it commands..200 squids maybe right...If not more. The Tal 150p is still at the top of my list at this time, the legs do un screw from the shaft of the stand, so even as heavy as it is it will be more portable than the dob....the 200p is nice though..head ache :-(
  14. twotter the 100r looks like one big momma!!...had a look at the one on ebay...the size of it dont look all that portable...the pine box must weigh a bit on its own...how are you finding using it? what results you had with it?
  15. Thank you for the replies so far...TAL looks to be a nose ahead of the dob at this stage in the race...it's a hard choice, but I am humbled when thinking back to the choices that amateurs had open to them back in the 70's....was watching the cover disc off this months 'the sky at night' magazine..it includes the episode of the sky at night that was aired backing 1973 and covered the African solar eclipse. The equipment on display being used to capture the event looked really cobbled together..lots of home construction going on....anyway, back on subject... I am open to the idea of trying something new with a different brand, the altare astro range of newts also looks good but I can't find that much about them by way of reviews on the Internet? Are they merely branded generic models from china? Possibly...any other suggestions as to what I should be looking at will be seriously considered... :-)
  16. Its been a long time since I was last active in the astronomy hobby...as a kid the only things to hand were some really old binoculars that dad found bank side on a fishing trip to norfolk back in the 60's. They didnt focus correctly and the only way to use them to any sort of effect was as monoculars. Later a set of Boots 10x50's turned up for a birthday ( still have them..will never part with them)..my seeing took a giant step for boy kind, and along with a copy of 'The observers book of astronomy' authored by Patrick Moore, these were the weapons in my armoury, and I loved my clear nights, sat in a deck chair in the family homes back garden in sheffield, gazing skywards ...roll forward to last christmas......... ...My dear 13 year old daughter requested a half capable camera for school work..my hobby of photography has rubbed off on her in a big way, hence her interest in capturing the world around her..the Lumix bridge camera santa delivered proved very capable at doing all it was asked to do, playing with the super zoom long focal length one evening we placed it atop a benbo tripod and aimed it at the moon. Within the space of twenty minutes we had produced some excellent images of the lunar surface...conversation got around to my early childhood days and those disfunctional fishing trip freebie binocs..and then it was suggested we may get a telescope...Ive been excited ever since!! Looking to what patrick had to say about telescopes in the observers book printed in 1976, ( yes still have that as well) he laments at the appalling scarcity of affordable telescopes and suggests that from time to time rare second hand ones come up on the market at affordable prices....but patrick this is 2013!...surely that cant be the same situation now? A quick glance at the internet shows a very different picture to the 1976 market!! Heavens above there are hundreds of the things!! WHAT TO DO?.... Visits to my best friends house in the 90's introduced me to TAL telescopes for the first time. My friends dad George Heppinstall ( much missed..lovely man) had a keen interest in astronomy and would regularly have his TAL 1 out on the patio day and night observing the moon in its different phases. I immediately liked the TAL.. my first SLR cameras had been Russian Zeniths and the chunky, heavy weight, armour piercing round construction just appealed straight away. Have to say the views seen through the eye piece of luna were spectacular. So, with TAL as my only 'have used it' refrence, the question must be asked, 'where do the russian scopes stand in todays market?'... first of all, Im not expecting blistering Hubble type images...I know the reality of whats achieveable on my budget of up to £500. I want a scope that is a bit of an all rounder...is there such a thing?. As much deep sky as £500 will get you, but something I can look at the lunar surface with in detail and pretend that I am Armstrong gearing up to make history. I would prefer reflector to refractor...I understand the importance of aperture and good optics...another reason why I keep looking at the TAL 150p..I understand the differences...deep sky and planetary are two different disciplines requiring different scopes...but my involvement is going to be 'as and when I have time for it'..the budget is only so big, as is the space to keep one scope never mind two..and then there is the wife to contend with..lets forget about that for the moment...eek!...and I live in a busy light polluted town centre..so perhaps an OTA that is transportable to a dark site is a requirement. On the other had I have been looking at the sky watcher 200p Dob and it looks blumming huge..but the simple construction and operation appeals! From the same stable I have been looking at the 200p and 150p explorers..as well as the Altair Astro newtonians, they really do look well made..but i know nothing of the brand..anyone have an opinion?..but the EQ3-2 and 5 mounts dont exactly look like grab and go devices...Im not fussed about putting a computer in the driving seat..it must be an old school thing!...last of all..i dont expect to take photos through this telescope that are going to end up on the cover of Sky at Night magazine.. but coming from the photographic hobby I would love to tinker a bit..even if its just aiming the camera lens down the eye piece..the moon would be my main target..so ladies and gentle man..your thoughts please...I have confused myself enough trawling the internet looking at scopes these last few weeks...i cant be confused any more!!!.........or can I ?...and all this time a little voice keeps saying to me''buy the TAL!''.....is that you George ? ........cheers
