Meade ETX-105
Maksutov-Cassegrain astro telescope with Meade #884 tripod and Meade #497 Autostar controller. D=105mm; F=1470mm; f/14 |

Meade #140 Apochromatic Barlow
With the camera this gives about 3670mm effective focal length or f/35. A superb lens. |

Scopetronix
STVB Visual Back for ETX To attach camera or Barlow + camera to the ETX rear port |

Scopetronix
STFD Field Doubler for ETX With the camera this gives about 730mm effective focal length or f/7. This lens has fairly bad comatic aberration. I prefer the Mogg focal reducer lens. |

Scopetronix
STDC105 DewClip for ETX Dew preventer heats the corrector lens to eliminate dew formation. Works great. Necessary for deep sky photography. Runs off 12V cigarette lighter socket. |

Steve Mogg F-0.6FR
focal reducer lens Threads onto 1.25" filter threads on the nosepiece of a camera adapter. This lens produces a nice sharp image across the whole sensor. With an extender to increase the distance between the lens and the sensor I get 0.55X reduction. |

Sirius
Optics NIR1 near infrared blocking filter, 1.25 inch
diameter Increases the sharpness of moon and planet images and preserves natural color when used with silicon chip image sensors. 1.25" IR block filters are hard to find. I got this one from Adorama. |

Scopetronix
STSF105 Class "A" Solar Filter The Sun appears yellowish white through this very nice filter |

Registax image "stacking" and processing software I haven't tried other stacking software, been completely satisfied with this one |

GIMP
image processing software A good, free, photo processing application. I do the final processing with GIMP including color balance and enhancement, gamma correction, gaussian blur, unsharp mask, etc. |

Compaq X1000 Notebook
Computer Nice machine. Batteries last for four hours of imaging. |
