From: Sgl - How To Use The Blogs

Posted by ant in SGL - how to do stuff., 07 June 2012 · 2,081 views


Hi All,

It'll take a little time to write all of these things up, but here is the first.

A guide to making an entry on your BLOG. Wasn't quite what I hoped adding content mid post, but I guess I still need to get...

In Search of Intermediary Motion

Posted by Geryllax Vu in Geryllax Vu's Blog, 26 July 2015 · 35 views

The question I want to ask is: can the following thought experiment detect absolute motion, or does a sort of intermediary motion emerge which is neither absolute motion, nor absolute rest? It is like Einstein relative motion, but without using a Galilean or Lorentz transformation between reference frames. It comes about when sound waves are used to inv...

Excitement mounts

Posted by Hawksmoor in Blog 19648, 24 July 2015 · 62 views

It's a very miserable afternoon in Lowestoft. It is raining and the sky is an unrelieved expanse of grey stretching from horizon to horizon. Early this morning the sky was clearer but not sufficiently devoid of cloud to permit the useful deployment of my 'scope. Due mainly to my overwhelming cheerfulness, I spent a happy pre-dawn hour with my 11x80mm bi...

Wide Field Ambitions . . . . . .

Posted by Nigeyboy in Toward First Light - And Beyond!, 21 July 2015 · 114 views

Hi all,  
So a quick blog today, just to keep things ticking over, and to keep track of my ideas etc – more for me to look back on more than anything else!  
Foot is a lot better now – I am getting around ok, and have even started a new fitness ‘regime’!! I have lost 6lbs in one week, by cutting out crisps and flapjacks, and doing 20 minutes...

Western Veil Nebula WIP

130pds, veil nebula

So the last week was kind and I managed another couple of sessions under the stars.
The lack of dark nights has made this a labor of love indeed. I have gathered 5 hours for each Ha pane so I have managed one of my bonus goals. Total integration time so far is 17 Hours:
 I may not add any more data to this until the darker skies return :sa...

Sky watcher star travel 102 problems

Posted by Phil42 in Phil42's Blog, 07 June 2015 · 612 views

Hi guys , I have just purchased this telescope and it's the first one I have had. I know nothing about astronomy only I wanted to buy one to attach my Slr to it to get some good photos. I have seen the moon close up but I am having problems seeing any stars as when you look through the viewfinder nothing appears to be in line through the scope . There is...

not much of an update.

Posted by crashtestdummy in crashtestdummy's Blog, 04 June 2015 · 355 views

Well what can I say, not much further forward than I was at the last update.The new lap I made worked out great and polished much better than the last one but the outcome seemed the same with a centre problem so I took my mirror on the 350 mile journey north to see John again.We tested my mirror for warping and that turned out ok, no warping or mirror dam...

Now is the winter of our discontent made glorious summer

Posted by Andy69 in Andy's Column, 27 May 2015 · 259 views

I originally wrote this one back in May last year and since it is time of the year relevant it make sense to post now. This one has a slightly nostalgic tinge to the usual mix of pop culture references and dubious facts wrapped around a vaguely astronomical theme.  
As we enjoy the longer days and the slightly warmer winter weather that here in the...

KRONOS 3T-65 parts

Posted by ToTo123 in ToTo123's Blog, 26 May 2015 · 330 views

Hi Everyone, 
Thank you for the warm welcome. As you can guess I'm new to this. I have just purchased a Kronos 3T- 65 telescope for very little money. I purchased it so my daughter could gaze at the skies at night as she has a few issues going out during the day. The telescope is in great condition but there is two items missing from the telescope. T...

Do we live in a black hole ?

Posted by Bert B in Bert B's Blog, 11 May 2015 · 439 views

I am told that a beam of light gets bent by the gravitational pull of our planet.

If so, the same beam of light will get bent every time it passes close to a celestial object.

As the beam of light travels through our galaxy and out into the universe, I imagine that it must constantly get bent by millions of objects.

As the beam of light gets further fr...

Imaging Jupiter

Hello, I am relativley new to astrophotography , and I have a question. I'm using a n 8 inch Shmidt Cassegrain Celestron Telescope, with a 2x Barlow and a webcam. I tried removing the lens from the webcam exposing the chip, however it completly ruined the image, I would just get a big blur of light and shadow, so I put the lens back into the webcam, and b...

Barlow or telecentric amplifier - What's the difference?

Posted by russ.will in Musings from The Fen Edge, 29 March 2015 · 764 views

It's a question that comes up regularly, but what is the difference between a Barlow and a telecentric amplifier (TA), otherwise known as a Powermate, ES Focal Extender. Meade Telextender, Bresser SA Barlow, etc? A telecentric amplifier does give a 2x magnification, just like a Barlow but that's where the similarity ends.

A Barlow is a negative double...

Dark matter and dark energy source

Posted by ngc6872 in ngc6872's Blog, 22 March 2015 · 780 views

I would propose the material currently missing from our universe was all there at the Big Bang moment but over the billions of years much has radiated off into the void. Every star,pulsar,quasar and black hole radiate out, from birth, their contents over time. Some of the material would be retained but much would be lost especially at the outer fringe of...

Hi. I have a Star-watcher 200P scope on a EQ5 Mount. Is it easy to upgrade it using a SynScan Go-To Upgrade kit for standard EQ5? If so please could you give me some tips to help?

It's been quite a few months now since I've been out for any serious sessions with the Telescope. However the bad habit of smoking does get me outside on a regular basis where naked eye observing was regularly taking place during those months.

My latest purchase is a GoPro Hero 4 Silver. Working in IT and having a love of gadgets the camera has opened up...

29/01/2015 - 30/01/2015 New toy day - laser alignment tool.

alignment, laser, 130slt

29/01/2015 - 30/01/2015 New toy day - laser alignment tool. I thought the 130SLT was working pretty well until I checked the collimation: way out. There should be a warning that your new scope will be off focus until a laser alignment tool is used and the collimation corrected. So that done I got the scope outside only to have the batteries die. Then I fo...

First night of 2015

Posted by lonick in A Rush And A Push And The Sky Is Ours or Astronomy, Here We Come, 18 January 2015 · 539 views

So the much belated start to 2015, while the real year started 17 days ago but, with the weather in Edinburgh having been on the terrible side of atrocious, the star gazing year only got going last night. For the first night of the year i thought i would do something a little different and i had my first night out at Harperrig Reservoir (Edinburgh). What...
