From: Sgl - How To Use The Blogs

Posted by ant in SGL - how to do stuff., 07 June 2012 · 1,739 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...


Barlow or telecentric amplifier - What's the difference?

Posted by russ.will in Musings from The Fen Edge, 29 March 2015 · 105 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...


Chasing the Eclipse

Posted by Hawksmoor in Blog 19648, 23 March 2015 · 115 views

As the weather forecast -Lowestoft seafront for the 20th March - was for cloud, cloud and more cloud, my partner and I set off for predicted 'clearing skies' in rural Lincolnshire. This required an early morning call at 4.30am. Strewth this was just like being back at worK! Anyway after quick coffee and cereal, we leapt into rhe 'family wagon' and heade...


Dark matter and dark energy source

Posted by ngc6872 in ngc6872's Blog, 22 March 2015 · 213 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...


The Mechanical Event

Posted by Geryllax Vu in Geryllax Vu's Blog, 18 March 2015 · 184 views

According to Galileo, Newton, and Einstein, the classical principle of relativity states that no mechanical experiment can be done to detect absolute motion, or motion of a material object relative to an everywhere stationary medium (similar to Michelson-Morley). A common reformulation of this principle states that:

♦ The velocity of any motion has dif...


EQ5 Upgrade

Posted by IenAABQDVmk32Xq in IenAABQDVmk32Xq's Blog, 14 March 2015 · 331 views

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...


Time for a new lap

Posted by crashtestdummy in crashtestdummy's Blog, 16 February 2015 · 261 views

I finally managed to test my mirror after going back to 600 to get rid of a centre problem and as soon as I got the mirror on the test rig in the dark I could see immediately that the centre wasn't polishing properly so I've decided that I'm going to start afresh with a new lap.I can't be certain yet that I've cured the centre problems but I'm hopeful and...


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 · 336 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...

I brought my son a 127 SLT Telescope for Christmas this year after seeing a few videos online.. I was taken back on what you can see with the scope and that is why I purchase one. After getting the 127 SLT setup I pointed the scope to the full moon and here I get a bright light. I tried focusing in the telescope focuser knob but still the moon shows up...


When shall we five meet again in thunder, lightning, or in rain?

Posted by Andy69 in Andy's Column, 10 December 2014 · 411 views

This week the challenge of finding a good dark sky site is tackled. Unsurprisingly the answer is to meet up with your local astronomy group which in my case was CLASS. Whilst your group and members will have different names I imagine the cast of characters will no doubt be similar.
Oh and Paul’s dog is actually called Tilly, the reason for pointing this...

Another damp cloudy evening

Posted by Alienfox in Alienfox's Blog, 23 November 2014 · 454 views

So I have had my scope for a month now and have had only about 2 hours with it in the dark pointing upward.

And again this evening another damp rotten evening, so it looks like it's back to the books for another read on Astronomy for the newbie, me, I have purchased 6 in last 4 weeks and have read about 3, so still a few more pages to plough through, it...
