Telescope Reviews: February Photo Competition

I don't know if this will make any sense, the translator is pretty bad, but I found only one translator on Google...

Cheap installment presents paralaktyczny, it is possible to assemble which (who) to several hours on him (it) theoretically issuing (seem) not more than 15 zloty < golden > - theoretically, because I has not counted it part < frequent >, I have found which (who) at in cellar ( but I think, that it is possible so conquests it (them) too ) darmochę. Biggest problem presents for grapple of photographic apparatus head it is possible to make her (it) -, but there will be enough problematic, it is possible to take old head from tripod - as has such, or buy rotary head with (from) case (together; time) grappling imadełkiem there will be simplest -, and also not cheap Rowi 80 zloty - Slik, Manfrotto 200 zloty - but it will be of use for for our installment not only. Principle of operation will be of use for theory ( a bit always ). About it behind movement of (traffic of) star walk hurry apparatus photographic and execute photos about long exhibitions, unused telescope as great dative (viewfinder). Fix-up, certainly < obvious > I will describe which (who) possible automate with proper transmission on here assembling engine prowadnicach, but then, problem would be with (from) to open air equipment wywiezieniem. Stars on sky around polar star arches ( approximately zataczają northern pole of sky ). Pole of sky is placed on northern equator in one on surface of horizon always point. In order to there follow stars suffice (enough) to turn down for table on hinges with (from) plank ( shoulder ) apparatus zamocowanym, put pivot on midnight (north) exactly zawiasów and bring up with proper speed or shoulder lower (go down) ( depend, hinges have been fastened from which (who) part, if to bring up it should be turn down after left part of plank in northern direction hinge want looking (look) ). Unfortunately, on other latitudes than 0 ° it is necessary to work enough a bit more ). It on luck for inclination of surface with perpendicular surface for surface of equator table fetch (come down) only said < allude > earlier so cover - or it is necessary to incline table under equal corner of latitude of place of observation. Stars to day full zataczają okrąg - or to 24 hours 360 °, it means, that in (to) 4 min. (face). They are removed about 1 °. Principle is such, that it is obliged to come up after 4 minutes about corner shoulder 1 °. Certainly < obvious > it will suffice (will enough) us, that (in order to) fix-up acted by max. Ok. 20 Min. (face) or corner will be changed about 5 merely ° we bypass several problems - due to it. Build it for considering to that remaining manner shoulder only, which (who) will be removed in definite time about required corner exactly. I will describe fix-up here, I have made which (who) in amount 5 hours for store with metal articles + walk. I have taken advantage following (step) part < frequent > table tops 3 felt 250x250 mm of leg shallow < plate > for net curtains karnisz and several polar listewek lunetka tube = 28 -mm PCV fi, peg from desodorant, from 4 hinge lunetka celownicza lunety Tasco, aluminum and steel blaszki and 46 bolt (screw) stuffing shoulder drewnowkrętów = 8 mm fi, dł. = 80 Mm, jump ergonomic = 1.262 mm ergonomic ) hand wheel from metal canister after sweets wieczko and building of carrying construction is very simple 15 bolts (screws), it don't forget about regulation of corner of inclination of table top it can be of use for - if you want to carry away installment on far journeys it ( rather endwise południków; ) ). Form of construction and they depend on it has been use largeness that bolt (screw) jump will be - that and one turn of bolt (screw) has to last from this what time. After measuring jump of bolt (screw) and it is possible to deal with determination of time of turn enumeration of distance bolt (screw) l - pivot [ ]. Here in any case I will not deduce (move out) it this exemplar simple (easy) ( be very ). Exemplar # 1 page (s) mm - jump bolt (screw) [ ] t sec - time (sometimes) 1 turn bolt (screw) [ ] l - distance bolt (screw) mm - pivot [ ] h for (after) 20 min. of (face of) work 240 - length bolt (screw) [ mm ] l = page (s) * ( / ) h = page (s) * 20 * 60 / jump bolt (screw) wypchniętej tg t t, page (s) [ mm ] time 1 turn of bolt (screw), sec [ ] t l [ mm ] h [ mm ] there should be on end of bolt (screw) dospawana kulka, which (who) would be point styku, does not have in my such prototype kulki, so, I must boost distance about 3 about radius of (ray of) end of bolt (screw) l mm ( ). It is obliged to be with proper speed simple bolt (screw) very Wkręcanie - if fix-up has to grant task as best. One turn of bolt (screw) should follow (step) in my installment that 75 seconds so, I have divided hand wheel from canister after sweets on 15 in proper places of bolts (screws) - ( ) part < frequent > wieczko wkręcając now it will be sufficed (will be enough) to stare in (to) - photographing stoper and perform that 5 seconds slip. On margin so I have run on idea - that (in order to) stick for for fishes by adhesive tape 12 hours shining bait ( candle stopera and they are cheap, it is possible to buy it (them) in stores ) wędkarskich. Setup of pivot of fix-up exactly is except accuracy in (to) on bolt (screw) important just polar ( wkręcaniu Gwiazdję though pole of sky is placed on near so ) prawde. It is proper to install in this purpose polar lunetkę or laser be . I had to install laser in plans such of pendant ( ), but as it has truth relatively to casing about many on eye cordially see that he (its; his; it) cluster it (him) thank ( saying exactly put pivot " " dewiację than with this laser assistant ). So, it is necessary to be precise fix-up it any (every) errors has wystrzegać. Behavior is most important as most exactly find (be placed) in my installment beyond plates distance bolt of (screw of) -pivot pivot ( l ) [ zawiasów, but over edge not exactly as it is presented on drawing beside calculator! ]. Next exemplar allows to define errors in execution this element of work. Exemplar be # 2 in angle (coal) measure ( ) t be sec - time (sometimes) 1 turn bolt (screw) [ ] page (s) mm - jump bolt (screw) [ ] l behind assistance of exemplar - distance bolt (screw) -pivot enumerated (account for) # 1 c min. (face) - time (sometimes) operation [ ] ex- < b > delay of work 240 page (s) be it - acceleration [ sec ] philippines = 3.14159265359 ex- < b > = ( * 60 / ) * [ * ( / l ) c t arctg it be delay of work 240 page (s) [ sec ] philippines = 3.14159265359 ex- < b > = ( * 60 / ) * [ * ( / l ) c t arctg delay presents outstripping in operation of fix-up after 15 minutes of work cause bad seat of bolt (screw) be There - ] diagram stuffing shoulder hour t. There be bad seat of bolt (screw) in operation of fix-up after 15 minutes of work outstripping cause stuffing shoulder hour . Examples are presented 4, jump of bolt (screw) is equal in (to) which (who) and it totals (take away; amount to) 1.262 mm, they differ from bolt (screw) only distance of pivot ( but that goes behind (for) on execution of one turn of bolt (screw) wanted sometimes it also ) pivot X error at distance of bolt (screw) from pivot of fix-up [ mm ]. Pivot Y delay acceleration of work be It . It be acceleration of work . Yellow diagram time of turn of bolt (screw) 120 sec, distance of pivot from bolt (screw) blue diagram 144.61 mm time of turn of bolt (screw) 75 sec, distance of pivot from bolt (screw) green diagram 231.38 mm time of turn of bolt (screw) 45 sec, distance of pivot from bolt (screw) red diagram 385.64 mm time of turn of bolt (screw) 20 sec, distance of pivot from bolt (screw) 867.69 mm important thing, I has not took into consideration which (who) be in my prototype in point arch shoulder styku - bolt (screw). Greatest corner is delay memorial < they (their) > it great wychylenia otherwise, fix-up is late gun it - saying memorial < they (their) > any longer more. But I think that photos elucidated executing max. It is possible to trouble inclinations of shoulders for 15 at small initial corner about it min. (face) ( ) not. Effect of work my at focal 135 -mm " " AstroMebla and it 8 min. of (face of) exhibition conceptual prototype ( my fix-up only, so, I do not concern on following photo delicate slip of star visible ). Photo presents constellation along with plainest star ( ) Lutni Wegą, line it along whole photo trail of some (certain) satellite running. Here, two part about a bit other montaży part of zbignev Kawalca, which (who) presents construction with electric drive ( ) Koziołka here the first time, I have informed it about such principle of operation of installment / ( http://republika.pl/kawalec, but I could not earn engine with proper transmission I have run on fine in simplicity at the end idea of building - " manual " ) Koziołka. English-speaking part of ulrich Beinerta / http://www.analemma.de. There miniature installment is presented, photographic tripod is base transmit (be suitable) for which (who) rather ( lens ) krótkoogniskowych. 17.09.2002: Mini koziołek: I have executed miniature version also ( ) koziołka AstroMebla. She (it) is suitable for practice of photo rather only lenses krótkoogniskowymi. Active time totals (take away; amount to) for 3-4 depending on accuracy of setup of pivot of fix-up on northern pole of sky min. (face) (. However, there is on it sufficing (enough) heeding, that then, it is possible to throw him (it) along with apparatus for small knapsack, when does not have capability forbid (carry away; get down) great version of fix-up, but there is yet better than nothing. Certainly < obvious > it is possible to put on tripod Mini koziołka, even if turn down for chair. There is that wanted for practice of photo behind (for) its (his) assistance except this that sole scrap of flat field ( be obvious ), watch, at plantation of pivot on a bit luck polish standard (national party). Pole of sky and a bit consistency ( but each will endure one-minute (-minute) exhibition 3 yet ). AutoZiołek: It does not exist already AstroMebel - but they have supplied him (it) new structure ( ) śrubki drewnowkręty astrografu. AutoZiołek As name indicate automatic be. It will suffice (will enough) to expose (to set out) him (it) in field on in due measure flat fragment of ground, regulate level (horizon) behind assistance of adjusted leg and target to northern pole of sky from polar star laser more or less ( 0.75 ° ). I have executed laser dative (viewfinder) from scrap of copper tube from central warming and from laser pendant. Pendant has been placed in tube and there is to similar manner zamocowany as in telescopes lunetki celownicze regulation becomes possible - due to it. It belongs as most exactly put cluster of laser so, in order to it was in due measure parallel for pivot of fix-up. It is possible to repair possible error in setup of laser turning shoulder astrografu there will be on sky - cluster laser zataczać okrąg is targeted in (to) center this district - pivot exactly so, everything it will suffice (will enough) to remove so -, in order to there pole of sky has been placed also. Say simply (easy) ( execute operations as described be identical - hardly ) principle earlier AutoZiołka AstroMebla. However, I have introduced many improvements. Regulation of upright is said < allude > one of them already. It is proper to call attention (to pay attention) on it also, that it is possible to distribute fix-up on 3 big part < frequent > and then, < sweat > again ( and no doubt, < unmistakable > that very fastly ) lodge boost (accrue) he (its; his; it) mobility. If as you can see, tongue (speech) it about mobility in my fix-up of regulation of corner of inclination of pivot for level (horizon) lack of course, makes impossible farthest journeys endwise - that ( południków, but fix-up has been designed for which (who) not parallel / 52 ° / ). However, has not to take over that it corner will suffice (will enough) to regulate behind assistance of leg - properly and ready I do not see problem for whole field - polish < poland >. Can be from ordinary supplied giving tense < tension > Silniczek zasilacza 9V, or from socket of car lighter. It gives tense < tension > Akumlator 12V, as at this tension a bit heat execute small appetizer (accessory) silniczek 7809 of turn down for it (him) - stabilizer radiatorem cool remains due to solution after very long work - even silniczek non-stop, but it is heated replacements for it radiator, but it will suffice (will enough) break that 30 min. of (face of) work. Electronic part it from old type of drive of diskette 5.25 " silniczek krokowy, head office engine ( ) sterownik krokowego and pilot (remote control) work taktujący sterownika. Engine on one in my fix-up turn of bolt (screw) execute 200 step ( which (who) total (take away; amount to) 75 second ). With the aid of digital (numeric) apparatus at 380 focal -mm not notice (remark) no oscillation ( test ). Shows imperfections in execution of fix-up about distance due to simple regulation on photo bolt of (screw of) -pivot that ( walk ) simply (easy) correct near. Due to it, that there is else simple (easy) become for shallow < plate > prowadnicą silniczka plexi. Otherwise, than this time I have executed arch in (to) under bolt (screw) at greatest corners ( correcting error work shoulder ) AstroMeblu wychyłu. I have executed him (it) from scrap listewki, I have profiled which (who) properly nożykiem, as well as bolt (screw) smoothly moves from scrap from casing from computer due to which (who) along arch at big loads of shoulders ( ) even blaszki zaślepka. I would like to thank the present (hereby) for facilities of project of pilot (remote control) mr. leshek Jędrzejewskiemu, for too sterownik silniczka krokowego and too < self-service store > silniczek, as well as this whole electronics for invaluable assistance in start-up, which (who) as it turns out guns as it belongs. But here, exemplary photo in open air behind assistance ( first ) executed Autoziołka
