This 3D printer makes a bit of a departure from my others in that it is designed to give the best accuracy I can achieve rather than concentrating on speed or size, though I did want to print at least as big as my Titan printer (290mm x 290mm x 250mm). Like Titan it uses a box as the main frame but unlike Titan and my other printers does NOT use "pink string and ceiling wax". It uses tried and tested 3D printer designs rather than my usual "way out" ideas. I took advice from a friend who has
A belated Merry Christmas and a Happy New Year to everyone! I do hope everyone had a fantastic time over the holidays.
Well, Santa has been very kind to me this year, and on Christmas morning I awoke to a huge box in the living room – it had been too big to wrap, and anyway I knew what I was getting lol!! So, I am now the proud owner of a Skywatcher Explorer 150PL. it was ordered from RVO at 4pm on Thursday afternoon, and arrived early on Saturday morning – great service!! I had um’d and ah
Invited by two of our children and grandchildren to meet them, early on Christmas morning, on the beach at Southwold for a swim. Had serious misgivings about this: as I dont do getting up early, I do not have a wet suit and recently have been under the weather. Anyway as my partner does have wet suit and was keen, a few bah-humbugs thrown in my general direction got me out of my 'toastie slumber chariot' before 8:00 UT and by 10:00 we were at the water's edge. There had been a hard frost over
As you may have read in one of my previous posts, my job with Greene King sees me coordinating till and IT installations during pub refurbs. Well, these last four weeks have been solid. We are trying to get as many pub refurb projects completed before the end of this month. Doesn’t do to have pubs closed at the busiest time of year! However, things are beginning to slow down on that front – although the meetings for jobs starting in the New Year are already coming in!
Based on some of my other clocks this will be a wall clock for my living room to go above the fireplace. It will have a dial of around 3ft diameter with a sweep seconds hand as well as the usual minute and hour hands. It will be driven by a stepper motor controlled by an Arduino Nano with Real Time Clock module to ensure excellent time keeping. Unlike other clocks it will not have any extras such as moon dial or striking, nor a pendulum. This will be of the simplest design using an epicyclic
So, been another busy week, but not so much travel – just been pottering around the local area which makes a nice change! Also means I get home at a reasonable hour! Had a good weekend – my 10 year old son and I went to the Donnington Car Museum for a look around. He is mad about F1, and when we saw two of Senna’s cars, he was over the moon! I read that it is closing down for good on November 5th, as they can’t afford to keep it open any more – such a shame, as there is so much history there.
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.
Well, it appears to have been over three years since my last Blog entry . . . . . so what's been happening?
Well, shortly after I my last entry, I was made redundant from my job as a Projects Coordinator. When I say 'Redundant', I was contracting, and the work dried up which was pretty crap. However, I wasn't out of work for long - got some more contracting work, and then just over a year ago I got a perm job with Greene King Pub Co. as a Regional Systems Manager - basically, I look after a
September - what I have observed with comments and rating out of 5 stars by constellation for this month
M13 ***** Quite open globular cluster, can make out individual stars around the edge and center, looks to be thousands of stars and seems very dense almost nebulous at the center. Best in 15mm EP and 2x Barlow
M92 **** Dense globular cluster, can distinguish individual stars around the edge, nice in the 8mm EP and barlow
Epsilon Lyrae **** - double dou
Looks good full index of constellations, objects by type and the charts are very detailed. Charts are organised in 8 ascention sections each by when visible in the evening, midnight and morning so all in all very logically set out.
Has a telrad finder symbol for star hopping which is a nice touch
Was hoping it would contain what to view guides etc but there is no such info but can get this elsewhere to plan observing sessions
Hope the pictures are useful as I never came across any
Clear Outside said it was to be a clear night so I got set up and set about tonight's challenge - Polar Alignment.
I've struggled to do this properly since I got the scope, lack of visibility of Polaris being the major issue as I set up close to my house facing south. I've now got the camera, mount and guide camera running through a USB hub and have managed to set up far enough from the house that I could see Polaris.
It took me a while to find the star, and longer to convince myself th
Having done a few nights observing with my new 200P Skywatcher I've found its too low for comfortable observing
So got a 9x50 right angled finderscope which had made things a lot better with positioning the scope as had the Telrad finder but the focuser was still too low for comfort having to crouch down all the time so went to the local garden center on the way home and bought a water butt for £10 which has worked a treat and had a good session observing Jupiter before the clouds inevitabl
After my experience with the standard finderscope on my 200P Sky-watcher and you having to either bend over the scope when looking low or crouching down on the floor when almost high vertically I ordered a right angled finderscope (https://www.firstlightoptics.com/finders/skywatcher-9x50-right-angled-erecting-finderscope.html)
Now fitted I can see its going to be so much easier pointing the scope and its also the "right" way around so up is up and left if left
With the finderscope fitt
First night with the new 8" 200P Skywatcher
Well after lots of cloudy nights finally managed to get a few hours observing with the new 8" 200P Skywatcher dobsonian
Firstly what is the 200P like to observe with - well after collimating it when it arrived I tested this on some bright stars and all looks good when viewing the stars when slightly out of focus, its bulky to move around but manageable as one piece. The finderscope is painful to use, you need to strain your neck to view low l
After doing my usual research\looking around the web I have bookmarked the following useful web sites I will keep this blog entry updated as I come across other useful websites;
Light polution web sites
I've used the first website to shorlist a few locations within an hours drive or so from my home for dark sky viewing
Interactive Observing Tools - such as Jupiter moon tracker \ Neptune tr
Since getting the telescope (a week ago) I have had no luck really with getting some observing in as there has been 100% cloud cover
But one evening early on before it got too dark I managed to view Jupiter and its 4 moons low in the sky with the new BST Starguider barlow lens and eyepieces
At the same time I setup the viewfinder so it was dead on using the 15mm eye piece
Well what can I say compared to my 4" reflector Jupiter looks great. Could clearly see the four galilean sat
In preparation for my first nights viewing (been cloudy since I bought the telescope) I readup on how the ZWO camera is used and supporting software
Firstly went to the ZWO website (https://astronomy-imaging-camera.com/software-drivers) and downloaded the following onto my Windows 10 laptop;
ASICAP software - to capture images with the camera
At the same time I also downloaded FireCapture (http://www.firecapture.de/) as this seems to be the most populate so
As I ultimately was to get images of what I observe I acquired the following book from FLO
Making Every Photon Count
read the first few chapters - is very good so far and aimed at the absolute beginner
I also bought 2nd hand Turn left at Orion
Ok book - pretty basic diagrams of the constellations and star maps\objects of interest (all in sketch form) but good enough to find objects of interest and there is info about them
Well being new to all this and doing much research and reading up I knew I would need to check the collimation of the telescope so bought a collimation cap for this
With the instructions provided with the telescope it was pretty straight forwards to do and as I have also watched a few youTube videos and read some how-to's so I knew what to expect and do
So firstly fitted the collimation cap and check things - things were not ideal (see attached image)
So using the instructions the
While waiting for the telescope to arrive I went and bought the the following;
Telrad finder - looks like a nice piece of kit and looks useful to star hopping as I plan to view deep sky objects (DSO) and the dimmer planets not visible to the naked eye
BST Starguider 2x short barlow lens
BST starguider 60 degree 15mm eyepiece
BST starguider 60 degree 8mm eyepiece
Rigel Aline Collimation Cap
The 200P Skywatcher 8" Dobsonian telescope arrived in two large boxes, one containing the base, tools and screws etc and another containing the actual telescope\tube and accessories (viewfinder \ eyepieces)
Assembly of the base was straight forwards and all the tools required were provided - allen keys \ screwdriver - overall took around 20 mins and due to its size is a little cumbersome for a single person but not an issue - once built seems sturdy enough
Telescope was very well packa
Is the blog like a forum, with blog entries being the threads therein ?
Or rather the entries like posts in a thread ?
PS: up to when can I edit the entry ? could that be used for evolving an initial publication ?
