    The centre light fitting in my living room is looking tired and I want to replace it with something funky that fits my interests, like 3D printing and clocks as well as astronomy, so my idea is a giant 3D printed gear wheel with five globes as shades for LED lamps.  The gear wheel represents both 3D printing and clocks which contain lots of gears.  The globes can represent moons or planets.  Thinking about this, I guess I could add a star in the middle - I'll give it some thought.

    All Sky Camera Mark 7

    By Gina,

    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 in use for some time. 
    This blog will describe the problems of the Mark 6 and report my progress in developing this new version.

    I'm starting with an empty area about 10 x 4 metres between sun lounge and observatory in front of living room window and facing roughly south.  I have killed off most of the weeds and grass by covering with an old tarpaulin for a year or so.  This has also stopped the ground from drying out and making it easier to dig.   In addition to providing a path to the observatory, this will provide flowers and shrubs to see from the living room window.  Plus a small pond and fountain.  The latter is something I have been working on in 3D printing and plan to have something unique.  Apart from the pond there will be planting areas and slabs and ornamental stepping stones.
    I have removed most of the tarpaulin and started digging a hole for the pond.  The latter is a pre-formed pond I bought from Amazon :-
    Bermuda Sand Pre Formed Pond 128 x 84 cm.
    Here are some photos of pond hole digging and the general area.

    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.

    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.

    Gigaclear have provided optical fibre cable to our village of Upottery in East Devon with full Fibre To The Property at 1Gb/s both download and upload.  We are the first village west of Bristol to be provided with this ultra-fast fibre broadband. 
    They provided connection to a pot (like a water D head) just outside my premises and I am arranging the fiber optical cable connection from there right into my house and to the router they have supplied.  This blog describes the process of digging a trench and laying the cable then running it into the house.

    Overview

    By Gina,

    This is my progress in buying, modifying and making 3D printers.
    Velleman kit UP Plus 2 - Proprietary 3D printer "GinaRep Pilot" created from the Velleman kit with variations and new parts "GinaRep Titan" - a larger printer with 300mm cube print capacity "GinaRep Giant" - larger still with over 400mm cube capacity "GinaRep Mini" - a replacement for the Pilot with improved accuracy and printing speed

    Test blog

    By Gina,

    I'm new to blogs - never used them before so I don't know what I'm doing   I'll just experiment and see what happens...
