Widefield Single Imaging Rig

This is based on the ZWO ASI1600MM-Cool CMOS astro camera and vintage film SLR camera lenses.  In particular the Asahi Pentax Takumar, Super Takumar and Super Multi-Coated Takumar lenses.  I plan to use this rig for LRGB and where I have only one lens of a particular focal length for NB imaging.  Between these is the ZWO EFWmini filter wheel.

Widefield Narrowband Dual Imaging Rig

This is a dual imaging rig using two ZWO ASI1600MM-Cool CMOS cameras and matching vintage SLR film camera lenses.  There will be no filter wheel and there will be one fixed filter per camera.  These will be Astrodon 3nm Ha and OIII.  A common 3D printed dew shield will be used.  This rig will be fully remotely operated with remote focussing and mount control using INDI/KStars/Ekos software and a Raspberry Pi to operate the rig.

Setting up a Raspberry Pi for Astro Imaging and Hardware Control

This is a tutorial explaining how to install an operating system and software into a micro SD card to use in a Raspberry Pi for astro imaging and control of the relevant hardware.  I have copied relevant posts from a thread in the Discussions - Software forum :- Tutorial :- Setting up a Raspberry Pi for Astro Imaging and Hardware Control

Setting up a Raspberry Pi for Astro Imaging and Control - Updated Feb 2020 for RPi 3B & RPi 3B+

INTRODUCTION This is a tutorial explaining how to install an operating system and software into a micro SD card to use in a Raspberry Pi 3B or Raspberry Pi 3B+ for astro imaging and control of the relevant hardware.  The software to capture images, control camera cooling and other things such as the mount etc. is called INDI and provides a set of drivers to control all the hardware. The Raspberry Pi will run in what is called "headless" mode - meaning that no human interfaces ar

Preparing a talk on Astro-photography

I've offered to give a talk with pictures to our local social group and thought a Blog on here would be a good place to prepare and assemble it.  Also, I would welcome any comments and suggestions.  I have a few ideas and will see how it progresses.  I will probably take me several days to get my initial ideas sorted out.

Modifying 28BYJ-48 steppers to run off A4988 driver modules (like NEMA 17)

I modify my 28BYJ-48 stepper motors to run off the A4988 driver modules, just like the Nema 17.   I use these for remote focus for my astro imaging. These motors come with centre-tapped coils with the centre-taps connected internally.  We need the full coils without the centre-taps and these need to be separate so the internal link needs breaking and center-taps ignored.  This in turn effectively changes a 5v rated motor to one that works fine with 12v. These photos show the coils and

Imagaging 2020

This Blog is to be a record of my imaging for this year including calibration data.

Ha Solar Imaging and Observing Rig

I have just acquired an Ha Solar telescope consisting of an Antares 127mm 1200mm FL telescope with Coronado PST.  I plan to set this up for both observing and imaging.  I have yet to decide on the final mounting for this but will start with a Skywatcher Pillar Mount with an NEQ6 SynScan Pro mount for testing as I want to reserve my EQ8 and main observatory for DSO imaging.

Gina's Ultimate All Sky Camera

I'm hoping this is my final and hence "Ultimate" generation of all sky cameras.  Based on the ASI185MC CMOS astro camera and Fujinon fish-eye lens of 1.4mm focal length and f1.8.  Image capture is provided by a Raspberry Pi 3 in conjunction with INDI drivers.  This is used with KStars/Ekos client software running on a Linux Mint desktop indoors.  Communication is via Wi-Fi.  The astro camera is an uncooled version but I have added a Peltier TEC cooler.  This cools the camera down to something li

All Sky Camera Mark 7

This is my latest generation of all sky cameras and based on the ASI178MM followed by ASI185MC CMOS astro camera and a Fujinon fish-eye lens of 1.4mm focal length.  Although rated at f1.8, this lens lets a lot more light through than this would imply.  Image capture is provided by a Raspberry Pi 3 in conjunction with INDI software.  This is used with KStars/Ekos client software running on a Linux Mint desktop indoors.  Communication is via Wi-Fi.  The Mark 6 ASC has proved inadequate after being

Adding 3rd Party INDI Drivers to RPi for Astro Imaging

This blog describes Installing 3rd Party Drivers into a Raspberry Pi having installed Ubuntu MATE and followed the instructions to run the AstroPi3 script to install INDI and other astro related software.  SSH has been enabled so that now the RPi can be accessed remotely from Terminal.  eg. ssh gina@rpi where gina is my user name and rpi is the computer name as set up during the Ubuntu MATE installation. This set up process is detailed in my blog :- Setting up a Raspberry Pi for Astro
