From: Sgl - How To Use The Blogs

Posted by ant in SGL - how to do stuff., 07 June 2012 · 1,694 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...


Man Flu

Posted by Hawksmoor in Blog 19648, 25 February 2015 · 156 views

Have been coughing and sneezing my way through February. When you add "am I feeling up to setting up my scope" to "are there clouds" to "is there too much moonlight" ?? Its all too easy to leave the scope in its box and rack up in front of the fire.
Anyway, the 21st February presented a fine clear night and I enjoyed imaging the ‘king of planets’.

Thursday 19 February 2015

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 · 166 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...


Established wisdom, or opinion parroted as fact?

Posted by russ.will in Musings from The Fen Edge, 13 February 2015 · 244 views
beginner, dob, 127mm, mak, goto and 1 more...

I threw an opinion into the mix in the beginners forum the other night and decided I should expand on my reasoning here.

Even somewhere as benign as SGL, you still have to remember this IS the internet. That means opinions repeated enough by people with large post counts, gain credence as fact among the rest of the forum. It does not hurt to challenge th...


One Velocity, Two Reference Frames

Posted by Geryllax Vu in Geryllax Vu's Blog, 31 January 2015 · 232 views

According to Newton and Einstein, the principle of relativity states that no mechanical experiment can be done to detect absolute motion, or motion of a material object relative to a stationary medium (similar to Michelson-Morley). Common reformulations of this principle state that:

1) The velocity of a material object takes on the simplest formula, a...


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 · 270 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 · 362 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...


Bright misty night

Bright and misty tonight.
Having a go at the M38 area.


Another damp cloudy evening

Posted by Alienfox in Alienfox's Blog, 23 November 2014 · 401 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...

SW 200 Dobson - Eyepieces - My mods

Posted by daiwelly in daiwelly's Blog, 10 October 2014 · 996 views

After changing my mind in July and going for the SW200 dob, I love it I have come up with a list of 2" eyepieces these include:
32mm panaview which will give me 38X mag, Purchased
SW SWA 22mm which will give me 55X mag on wish list
SW SWA 8mm which will give me 150X mag on wish list

We're off and running..... well, walking.... well, maybe just milling around a bit.

So it's happened!

I've got a scope.

My initial intentions of getting a small refractor were well and truly side-swiped by RobH on here doing me a corking deal on his ST120.
Having thrown in some extras including the dovetail and scope rings, a basic electronic focuser, an old EQ3 mount and a couple of eye pieces within the price I came away a very happy...



Posted by andyin2014 in andyin2014's Blog, 30 September 2014 · 511 views

I will be traveling by car and want to transport my telescope. I have a refractor and I understand this type is the safest to transport, any advice?
