IMT3b – Build Part II

2nd December 2020

So now the work begins. How to turn a vegetable patch into an observatory. The first thing any good person does when moving into a house is perform a harvest! So we set about harvesting and found some rather large parsnips (which we have been having every Sunday lunchtime since) 🙂

Once done, we removed the edging boards and marked out the dome diameter using the stakes we found in the garden.

Once done I left Luke to dig the rest of the dome base out with a little help from my daughter and as you can see digging in a vegetable patch is rather easier to start with than hard ground due to years of using the land.

Dome base dug out….but what about the pier hole?

Okay, so that’s the dome base which is a nice 6″ deep. Next, which was a slightly bit more problematic was to dig out the pier base through chalk to a depth of 65cm x 1m wide. Yes I know I am mixing my scales but that is because I can 🙂

I then had to wait several weeks for the weather to improve before I could start creating the former for the hole.

I must add at this point, that despite building and installing many domes before, I sought out the experience as one should, of another astronomer and friend, Nigel, who sent me a well prepared document of contracting a concrete base, that I have used as extra guidance on this dome build.

Next up will be more preparation for the foundations and connecting the electric and ethernet from the house some 100m away the way I have to run the cables!

IMT3b – Build Part I

21st November 2020

So after the shortest time in a house, I have now moved to a much better astronomy home, surrounded by fields and forests, ancient woodland and with some of the darkest skies in the North Hampshire Downs. I am fortunate in my location, however less fortunate that the build of this observatory, unlike my other observatories is happening in the middle of a pandemic of Covid-19. This as you will see makes it extremely hard when you can’t have astronomer friends over to help with the preparation and installation.

The move started to with the dismantling of IMT3 and in the final days at the previous house we dismantled the dome, at least at the time I could have some friends over to the garden to help with Mil Dave, Alan and Shane lending a much needed hand.

Dome has gone!

So on a quick dismantling, which was much quicker than constructing the astronomers put the dome segments on the lawn 🙂

Oh there it is 🙂

However as I found that night when a storm front came through, which caused me and my daughters boyfriend to get up after midnight to secure the dome segments in a more wind resistance piece of the premises.

The following day Luke has had his first angle grinding lesson to take out the remains of the bolts and plugs which to be honest I think he really enjoyed.

Then the moving day came and I put all the important scientific astronomy equipment in my old Landy to make sure it got there safely.

whilst the rest of the observatory went in a further truck kindly supplied for free by our removal company who are the best removal company ever! Thanks Camberley Removals!

IMT3 tucked up and ready for shipping

By mid November, some 4 months after we accepted an offer on the house I landed up with my new more astro friendly observing location surrounded by fields.

IMT3b Location is a vegetable patch

Next up is removal of the local vegetation and preparing the ground for concreting.
