Figure 1. The Orion 70mm Multi-Finder (MF70).Congratulations on your purchaseof the Orion 70mm Multi-Use FinderScope (MF70).The finder scope is an invaluable toolfor finding objects in the night sky. It isa miniature telescope that mounts ontoa larger telescope. Because of its lowmagnification and wide field of view, itis much easier to first locate and centeran object in the finder scope beforesubsequent viewing through the maintelescope. To properly install and useyour finder scope, please read thisinstruction manual.Figure 2. Field of view (FOV) usingthe MF70 with a 15mm Eyepiece(approximately 4 degrees FOV).70mm Multi-Use Finder Scope (MF70)The MF70 is a large aperture finder scope. Its large 70mm aperture capturestwice the amount of light than a conventional 50mm finder scope.The light gathering power can be calculated as follows:Divide the telescope aperture (in mm) by 7mm (dilated pupil diameter of ayoung person) and squaring the result.50mm Finder Scope (50/7)² 51x70mm Multi Finder (70/7)² 100xHence the MF70 captures twice the amount of light than a conventional 50mmfinder scope2
Figure 3. If more in-focus travel is required a 90 degree Prism Diagonal may be required. A45 degree Prism Diagonal requires more in-focus than any other diagonal.With its fast focal ratio (f/4) the MF70can be used as a wide field of view(FOV) telescope or as a very brightfinder scope or guide scope.Field of View (FOV)It is important to understand that awide field of view is what makes afinder scope a special tool. It allowsviewing a vast portion of the skies withlow magnification.Use a low power eyepiece to get thebest FOV with the Multi-Finder. We recommend an eyepiece focal length of15mm. This will give about 18x powerwhich is good for resolving faint starsand even to observe some deep skyobjects.Diagonal Focus Distance ChartBrand/TypeFocusDistance(mm)Orion 90 degree prism74Orion 90 degree mirror94Orion 45 degree prism102Vixen 1.25” Prism63Takahashi 1.25” Prism64Baader T2 Prism (Zeis)67Celestron 1.25” Prism67Vernonscope 1.25” Silver mirror73Teleview 1.25” Everbrite Dielectric78Astro-Tech 1.25” Dielectric94Figure 4. Example diagonal types and theirassociated focus travel distance.Reaching Focus With the 70mMulti‑FinderThe MF70 has a very limited focus range of approximately 0- 15mm. Some eyepiece and diagonal combinations may not come to focus.The light path distance of the MF70 is approximately 80mm therefore youwill need to select an accessory and diagonal combination that is within thisrequired spacing distance in order to achieve focus.Generally the rule is: if focus cannot be reached with a particular combination ofeyepiece and diagonal then it is recommended to change the diagonal for a 90degree prism diagonal which requires much less focus travel than other diagonals(Figure 3 & 4). The eyepiece may also be exchanged for one with a smaller focustravel requirement (Figure 5).When used as a finder scope we recommend using a 90 degree prism diagonalwith eyepieces. When used as a guide scope we recommend using a 90 degree3
mirror diagonal with guide camera.When used as a terrestrial spottingscope for near objects we recommendusing a 45 degree prism diagonal.Getting StartedThe MF70 comes fully assembled. Youonly need to use a standard 1.25” diagonal prism/mirror (not supplied) and astandard 1.25” low power eyepiece (notsupplied) to start using it.The MF70 can also be used in severalconfigurations.Start by installing the MF70 into thedovetail base of your telescope (Figure6). Tighten the dovetail base thumbscrew in order to securely attach theMF70 to your telescope.Insert the diagonal prism/mirror intothe helical focuser (Figure 7). Use theeyepiece thumbscrew to secure thediagonal.You are now ready to choose froma variety of accessories such aseyepieces and reticle eyepiece forvisual or photography work, or a guidecamera such as the Orion StarShootAutoGuider for guiding.Focusing the Finder ScopeLoosen the rotation locking thumbscrew so that the helical focuser canrotate to adjust focus.Loosen the eyepiece thumb screwand hold the diagonal (with eyepiece)with one hand to keep the diagonal inplace against the helical focuser. Sinceadjusting focus rotates the helicalfocus, the diagonal too would rotate ifit was locked down with the eyepiecethumbscrew.Eyepiece Focus Distance rascopic35-12OrionSirius Plossl3221OrionSirius Plossl200OrionSirius Plossl100ExploreScientific82 Degree4.76CelestronPlossl9-8MeadeSWA165MeadeSWA243 pticsUWAN162 1/2BrandTele VueEthos8-5 1/2Tele VuePlossl4012Tele VuePlossl324 1/2Tele VuePlossl324 1/2Tele VuePanoptic245 1/2Tele VuePanoptic195 1/2Tele VuePlossl156Tele VuePlossl116Figure 5.

piece thumbscrew itself can be usedas a lever to adjust focus.When focused is reached lock downthe eyepiece thumbscrew. Tiny adjustments can be made before finally locking down the rotation locking thumbscrew to lock the focuser position. Thethumbscrew should only be slightlytightened to avoid damage to the internal threads.Use the Multi-Finder As a LargeAperture Guide ScopeSmall aperture finder scopes offerlow weight and a low cost solution forguiding with a guide camera. They arehowever limited by the light gatheringcapability.Figure 6. Installing the MF70 in theDovetail Base.The MF70 boasts a huge 70mm aperture. This will have a dramatic effect onthe amount of stars seen by the guidecamera, and increases the chance toget a suitable bright star for guiding.Due to its large aperture, light weightdesign and ability to be accurately centered, the MF70 makes an excellentguide scope.Figure 7. Multi-Finder with a low powerEyepiece.Cameras normally have a very smallback focus requirement and therefore along extension/spacer or mirror diagonal should be used in order to reachfocus.This same setup will also work withCCD cameras to turn your MF70 into awide field astrograph.Use the Multi-Finder As a SmallFigure 8. Multi-Finder with a reticleAstrographeyepiece for precise centering.At f/4 the MF70 provides very brightimages. Use a dedicated astrophotography camera, such as the StarShoot G3 camera, with the MF70 to get deep skyimages of wide nebulosity or star field of the Milky Way.The MF70 can even be used with a DSLR camera by using the T-threads on theMF70 to attach the camera (Figure 10).5
The light path distance of the MF70 isapproximately 80mm so you need tocalculate the required spacing distancein order to achieve focus with the camera.For a DSLR camera, with T-threadadapter, a 25mm spacer is required(not included).We recommend using the #05528Orion T-thread Spacing Ring Kit orthe #05326 Orion Variable 12-17mmT-thread Spacer Ring to get the bestspacing combination.Figure 9. MF70 with StarShoot AutoGuiderguide camera.For the StarShoot AutoGuider or theStarShoot G3, the required spacingis approximately 70mm. This can beaccomplished by using the camerawith a mirror diagonal.How to Use the ProvidedSpacers (7mm & 15mm)The spacers are used to add additionalspacing. This might be necessary forcertain mirror diagonals that requirethe focuser to be too far out. Adding thespacer provides more stability to themechanism (Figure 11).Figure 10. Small Astrograph use with aDSLR (for full frame cameras there may besome vignetting on the frame edge).The spacers may also help to providea grip to adjust the helical focuser.Remove the eyepiece thumbscrewfrom the focusing tube (Figure 12).Thread the spacer to the focusersT-threads and re-insert the eyepiecethumbscrew (Figure 13)Lock the spacer with the lockingthumbscrew (Figure 14). This prevents the spacer from getting loose. Ifrequired, combine the two extenders toreach maximum spacing of 22mm.Figure 11. MF70 with 15mm spacer added.We recommend using the #05528Orion T-thread Spacing Ring Kit or the #05326 Orion Variable 12-17mm T-threadSpacer Ring to reach other additional spacing combinations.6
Weight BalanceThe MF70 was designed to beextremely light weight. By adding anoptional prism/mirror diagonal andeyepiece, the total weight can increaserapidly. Adjust your telescope rings tobalance the telescope.For Dobsonian telescopes you mightneed to add some counterweight tothe back of the telescope to get perfectbalance.Adjusting the Aim of the MF70Now that you have your installed theMF70 and chosen one of the configurations that best suits your observingneeds, it is time to adjust the aim ofyour MF70.The finder scope has a wide field ofview to facilitate the location of objectsfor subsequent viewing through themain telescope, which has a much narrower field of view.The finder scope and the main telescope must be aligned so they pointto exactly the same spot in the sky.Alignment is easiest to do in daylighthours.Figure 12. Removing the thumbscrew.Figure 13. Re-inserting the thumbscrew.First, insert an eyepiece into the maintelescope and point the telescope at anobject such as the top of a telephonepole or a street sign that is at least aquarter-mile away.Move the telescope so the targetobject appears in the very center ofthe field of view when you look into theeyepiece.Figure 14. Secure the spacer with thelocking thumbscrew.Now look through the MF70. Is the object centered in the finder scope’s fieldof view? If not, hopefully it will be visible somewhere in the field of view (FOV),so that only fine adjustment of the MF70’s adjustment screws will be needed tocenter it on the FOV. Otherwise you’ll have to make coarser adjustments to theMF70’s adjustment screws to redirect the aim of the MF70.7
The best method for adjusting the aim is to loosen one of the adjustment screwswhile tightening another adjustment screw.Once the target object is centered in the FOV of the Multi-Finder, look againin the telescope’s eyepiece and see if it is still centered there as well. If it isn’t,repeat the entire process, making sure not to move the telescope while adjustingthe alignment of the finder scope.When the target object is centered on the FOV of the MF70 and in the telescope’seyepiece, the MF70 is aligned and ready to be used for locating objects. Makesure all the adjustment screws are now locked down tightly so that the MF70’saim will stay the same as the telescope moves from target to target.The Multi-Finder alignment should be checked before every observing session.This can easily be done at night, before viewing through the telescope. Chooseany bright star or planet, center the object in the telescope eyepiece, and thenadjust the bracket’s adjustment screws until the star or planet is also centered inthe MF70’s FOV.The MF70 and bracket can be removed from the dovetail base for storage, andthen reinstalled without significantly changing the Multi-Finder’s alignment.Warning: Never look directly at the Sun with the naked eye or with a telescope– unless you have a proper solar filter installed over the front of the telescope!Otherwise, permanent, irreversible eye damage may result.Caring for the Finder ScopeIf you give your Multi-Finder reasonable care, it will last a lifetime. Keep the dustcap on the finder when it is not in use. If you plan to move your telescope anysignificant distance, you should remove the Multi-Finder and bracket in order toprevent them from getting bumped. You can store the Multi-Finder in any smallpadded case to protect it from damage.Cleaning LensesAny quality optical lens cleaning tissue and optical lens cleaning fluid specificallydesigned for multi-coated optics can be used to clean the exposed lenses ofyour finder scope. Never use regular glass cleaner or cleaning fluid designed foreyeglasses. Before cleaning with fluid and tissue, blow any loose particles off thelens with a blower bulb or compressed air. Then apply some cleaning fluid to atissue, never directly on the optics. Wipe the lens gently in a circular motion, thenremove any excess fluid with a fresh lens tissue. Oily fingerprints and smudgesmay be removed using this method. Use caution; rubbing too hard may scratchthe lens. For larger lenses, clean only a small area at a time.8
