That is normal. Finder scopes are only used to make objects easy to locate. The image orientation does not matter for observation.

  • Alt-azimuth: easy to use, moves horizontally and vertically
  • Equatorial: enables precise tracking of objects with only one axis – ideal for high magnifications and astrophotography

  • Moon: from 30 mm
  • Planets: from 100 mm
  • Deep sky: from 150 mm

Warning notes
  • General safety instructions DANGER Risk of eye injuries! Never look directly at the sun or near the sun through this device. There is a risk of blindness! Children should only use the device under supervision. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! FIRE HAZARD! Do not expose the device especially the lenses to direct sunlight! The light concentration could cause fires. RISK of material damage! Do not dismantle the device! In case of a defect, please contact your dealer. They will contact the service center and may send the device in for repair. Do not expose the device to temperatures above 60°C!
  • Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
  • Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
  • Do not expose the device to high temperatures.

EXPLORE SCIENTIFIC ED APO 102mm f/7 Alu FCD-100 Alu HEX
Highly corrected 102mm air-spaced triplet apochromat (with three lenses) and aluminium tube and a 2.5" high-precision HEXAFOC focuser.   Apochromats are the ultimate choice in small to medium sized telescopes: the combination of compactness, transportability, very high image contrast and sharpness together with the possibility to make excellent astrophotos cannot be bested. The advances in glass manufacturing during the last few years have made true apochromats available to more astronomy enthusiasts than ever before. The new Explore Scientific FCD-100 Alu Hex represents another major improvement in this field - the overall correction (color and spherical) is setting new standards in this price class. The optical design shows a polystrehl value of 0,97 indicating a level of correction that is absolutely top of the line.This excellent apochromat is a very versatile telescope: the fast f-ratio makes short exposure times possible. The high contrast and sharpness of the image provide breathtaking views of large objects like the North america nebula or the Andromeda galaxy as well as tack sharp planetary images. The telescope is lightweight and compact - the dew shield slides down the tube to minimize size for transportation. Revolutionary glass and precision manufacturing created a telescope that offers observing joy on the highest level. This does not only qualify this telescope as the ideal travel scope, it is also the perfect choice for fast observations and for astrophotography. The excellent 2,5" HEXAFOC focuser with 10:1 reduction is perfect for this - the large inner diameter of 65mm prevents vignetting by the focuser when the telescope is used for astrophotography with large sensors. These very popular EXPLORE SCIENTIFIC Triplet ED APO Refractors we do offer in 3 different product lines:Essential Line: HOYA FCD-1 Glass lens, AL-Tube, 2.0" Rack&Pinion Focusser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112084(AL), 0112106(AL), 0112132(AL)), 0112155(CF + 3"FT)) Professional Line: HOYA FCD-100 Glas lens, AL/CF-Tube, 2.5" HEXAFOC Focusser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112086(AL), 0112108(AL), 0112109(CF), 0112134(AL), 0112135(CF))High-End Line: OHARA FPL-53 Glass lens, Carbon(CF) Tube, 3.0" Feather-Touch Focusser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112165(CF))SPECIFICATIONSAperture: 102mmFocal Length: 714mmFocal ratio: f/7.0Weigth: 4,0kgBackfocus: 150mm above 2" adaptorDesign: Apochromat with three lenses, two air spaces and FCD-100 glassSCOPE OF DELIVERYOptical tube with retractable dew-shield2.5" HEX focuser with 1:10 gear reduction  2" Star Diagonal 99% reflectivityTube rings with dovetail plate and handleDust caps for front-lens and focuserUniversal finder slot

BRESSER Full HD Deep-Sky Camera & Guider 1.25"
BRESSER Full HD Deep Sky Camera with autoguider: a great camera for different types of astrophotography and for autoguiding. Not only suitable for planets, but also for deep-sky objects such as galaxies, nebulae and star clusters. Dedicated ToupSky Astro Imaging software supports video preview, video recording, video processing, image capture and processing, dark field correction and raw data output. Easy to use, but with professional results.One of the main features of the new backlit SONY IMX290 CMOS sensor is its high light sensitivity, which makes it possible to detect deep-sky objects without active cooling. SONY has increased the quantum efficiency at 533 nm wavelength up to 77%, which is much better than other CMOS sensors have been able to achieve in the past.Connect this camera to a guidescope and attach the camera's built-in ST-4 port, directly to your telescope's equatorial mount guide port and autoguide - using many popular audioguiding programs (PHD, Guidedog and more). Autoguiding enables you to take accurate pictures with long exposure times of several minutes. Thanks to the extra light-sensitive camera, you now always have a suitable guide star to hand, even using short exposure times. An ST-4 protocol connection cable is also included. Simple automatic tracking at its best.You can use this camera with all guiding telescopes, or off-axis guiders that accept a 1.25 " tube, 1.25" filter thread (M28.5x0.6) or C-mount adapter thread (1 "x1 /32").IMPORTANT NOTES:This is not a stand-alone guider camera. You always need a Windows 10/11 computer to take pictures and for autoguiding.The autoguider software is not included. You can use PHD2 Guiding, Guidedog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).DOWNLOAD PHD2-Guiding: https://openphdguiding.org/DOWNLOAD GuideDog: http://barkosoftware.com/GuideDog/index.htmlDOWNLOAD latest camera software and drivers: https://www.touptek-astro.com/downloadsDownload INDI Driver: https://github.com/indilib/indi-3rdparty/tree/master/indi-toupbaseSPECIFICATIONSCamera type: BRESSER / Touptek GPCMOS02000KPA colorSensor: SONY IMX290 CMOS color, backlitImage and video size: Full HD 1936 x 1096 pixels (video 15 FPS)Native sensor size in pixels: 1936 x 1096Exposure times: 66µs to 16minBinning: YES, 2x2Megapixel: 2.1 MPSensor size in mm: 5.6 x 3.1Pixel size: 2.9 µm x 2.9 µmBit depth: 8/12 switchableST-4 Compatible Autoguider: YESCNC milled housing made of aluminumProtective strap on the camera housingCamera tube diameter: 1.25 "(31.7 mm)Camera connection thread: C-mount + 1.25 "filter threadComputer interface: USB 2.0C-mount extension tube with 1.25 inch filter thread includedNo IR cut filter installedCompatible systems: WINDOWS 10 + 11, Linux, StellaVitaASCOM driver includedField of view for different focal lengths in mm (given in arc minutes):400mm - 48.2 'x 27.3'500 mm - 38.6 'x 21.8'600 mm - 32.1 'x 18.2'700 mm - 27.5 'x 15.6'800 mm - 24.1 'x 13.6'900 mm - 21.4 'x 12.1'1000 mm - 19.3 'x 10.9'1250 mm - 15.4 'x 8.7'1500 mm - 12.9 'x 7.3'1750 mm - 11.0 'x 6.2'2000 mm - 9.6 'x 5.5'SCOPE OF DELIEVERYFull HD cameraC-mount adapterUSB 2.0 PC connection cable with a length of 200cmInterface cable for ST-4 autoguider port with 150cm lengthDust cap for camera tubeSoftware download
