From: Sgl - How To Use The Blogs

Posted by ant in SGL - how to do stuff., 07 June 2012 · 1,907 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...


Western Veil Nebula WIP - framing and first pane

Posted by Robp in The Western Veil Nebula WIP report, 28 May 2015 · 56 views
veil nebula, 130pds

So I used a CCD field of view calculator to work out the framing of the nebula. I left a little overlap between the two panes. The image of the nebula in the framing isn't my own, but the default image provided by the calculator:
 The target is very low on the horizon at the moment and within the most light polluted portion of my available sky....


Now is the winter of our discontent made glorious summer

Posted by Andy69 in Andy's Column, 27 May 2015 · 81 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...



Posted by Hawksmoor in Blog 19648, 26 May 2015 · 116 views

I look forward to Saturn coming to opposition each year or each 378 days to be precise. The sky over our backyard in the early hours of the 24th of May was clear and the stars shone bright. In the east, the stars of Cygnus and Lyra were shining brightly and Saturn was a brightish yellow presence due south over my neighbour's house rooftops. Through the e...


KRONOS 3T-65 parts

Posted by ToTo123 in ToTo123's Blog, 26 May 2015 · 123 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...


Reconsidering Equipment Choice . . . . .

Posted by Nigeyboy in Toward First Light - And Beyond!, 21 May 2015 · 174 views

So, not bought any further equipment since the EQ3-2. I have been spending perhaps too much time browsing the forums. This has its positives – it gives me other ideas to consider, and on the negative side – it gives me other ideas to consider lol!! But in all seriousness, it has stopped me rushing out and getting stuff that I either won’t need in 12 month...


Do we live in a black hole ?

Posted by Bert B in Bert B's Blog, 11 May 2015 · 278 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

Posted by Investigate911 in Investigate911's Blog, 03 May 2015 · 333 views

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...


The Magick Carpet Ride

Posted by Geryllax Vu in Geryllax Vu's Blog, 03 May 2015 · 240 views

A young woman and her two wyrd sisters are practicing their mysterious magicks tonight. They will exercise their telekinetic and mathematical skills with the levitation of a massive material object. In their alchemical experiment they will test whether two events that would appear simultaneous in a reference frame that is at rest, would these events st...


Barlow or telecentric amplifier - What's the difference?

Posted by russ.will in Musings from The Fen Edge, 29 March 2015 · 611 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 · 634 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...


EQ5 Upgrade

Posted by IenAABQDVmk32Xq in IenAABQDVmk32Xq's Blog, 14 March 2015 · 572 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 · 432 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 · 449 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...
