  1. Hi everyone, My partner bought me a second-hand Tasco 302911 and I'm keen to get out and use it. I have read that these are not the best scopes but as I am a complete and utter beginner I'm not too worried about that right now. Can anyone point me in the right direction (to articles, YouTube videos etc) which can help me to understand the absolute basics of setting up and using a telescope like this? I have no clue what any of it does and any instructions I've found are all in a foreign language to me (all the jargon is difficult to wade through rather than the instructions being in French!). Any pointers for a total beginner would be gratefully received. Thank you in advance
  2. I'm having problems with my new crayford focuser I fitted to my modified Tasco 17TR. The scope is an early 90's 80mm refractor with a focal length of 900mm. The problem isn't apparent when viewing planets, etc, it's when I try to use my camera (Nikon D80) or web cam (SPC880 modified). With the original focuser, the focal range (focuser movement) was from 840mm (measured from the lens) through to 1040mm. With the new crayford and adaptor the focal range is from 910mm through to 990mm. SInce fitting the focuser, I get beautiful, clear views of Saturn and the rings, Mars, basically everything I've turned it towards but, I can't get the focal range for photography. The focal point is shorter than what I can obtain as it is. Last night, I removed the 1.25" adaptor and held the web cam head inside of the 2" eyepiece holder and could obtain focus (albeit wobbly) so I'm thinking I need to cut my tube down. Any advice?? Before you ask why I'd bother, this telescope has a previous mod done in 97, the fitting of a Vixen ED series lens and the quality is stunning, now if I can get my focal point correct for photography I'll be very happy. I can't modify the adaptor (a cost of $150 to get it machined and that's with me providing the stock and design) but I'm not overly keen on trimming the tube down. I can't see any other options though. If I cut the tube down and it's short for visual purposes I can run a 2" or 1.25" focal extender tube (80mm length seem common and readily available). Thanks! Tasco 17TR with Vixen ED lens, Williams Optics Crayford focuser, home made tube rings mounted on Skywatcher EQ3 Pro GOTO mount
