These Tips And Tool Will Assist You In Decision Of Astrophotography Set. Note That Wide Angle, Medium Angle Planetary/Lunar And Solar Requires Slightly Different Equipment

1. High Zoom VS Wide Angle Imaging

• Calculate Your Imaging Field Of View (FOV) Using This Tool - FOV CALCULATOR

2. Equatorial VS Alt-Azimuth - EQ For Long Exposure DSO, ALT-AZ For Short Exposure, Planetary, Lunar, Solar. 

3. CCD Pixel Size - Resolution Matching - CCD MATCHING

4. Telescope And Mount Payload Matching - Ideally Equipment Should Peak Around 75-80% Of Rated Mount Capacity

5. Equipment Choice

• Planetary, Lunar, Small DSO - Higher Focal Length Telescope (SCT, Newtonian, RC)
• Medium DSO, Full Moon, Full Sun - Medium Focal Length (Newtonian, Refractor, RC)
• Wide Field DSO - Short focal Length (Refractor)
• Ultra Wide Field - DSLR + Wide Angle Lens
