From: Sgl - How To Use The Blogs

Posted by ant in SGL - how to do stuff., 07 June 2012 · 2,379 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...


More Jupiter Imaging

Posted by JohnSadlerAstro in JohnSadlerAstro's Blog, 28 November 2015 · 51 views

I got up at some unspeakable hour this morning, and found that the sky was not only clear, as had been forecast, but also that the seeing was very good! I had some trouble focusing, but I think most of the images turned out ok. I'm processing at the moment, images to follow! The bahtinov mask that I made seems to work, but it sometimes cuts of a bit too m...


Piston broke...... or rather I will be shortly !!

Posted by ASTROSTUART in ASTROSTUART's Blog, 12 November 2015 · 220 views

Well a productive week and weekend, new piston arrived and was fitted and then the engine refitted on Saturday afternoon / evening. A transmission fault, being stuck in reverse gear ( automatic gearbox) meant i couldnt start. So Monday morning the diagnostics was connected and the gearbox error sorted out, much to my relief the engine has started as run...


EQ3 mount not as bad as is claimed?

Posted by Stub Mandrel in Stub Mandrel's Blog, 07 November 2015 · 355 views

Last night I took 35 80 second subs using my camera with a 400mm tele lens mounted next to a 70 x700mm scope on my EQ3 mount on an EQ5 tripod. Quick and dirty aligned using the polar scope, no drift align. 
Over 1 hour 7 minutes, the images offset by a total of 32 pixels vertical, 8 pixels horizontal, but almost all the horizontal drift was on the fi...


Components, Progress and Plans

Posted by Dwarf Nova in Orkney Observatory, 03 November 2015 · 255 views

Concurrently with the dome assembly, I am cobbling together the potential contents. Initially, I intend to install my HEQ5+250mm f/4.8 Newtonian on a tripod.  Have tested mount operations successfully indoors with indilib on a RaspberryPi, remotely connected to KStars. I think indilib (http://www.indilib.org ) is brilliant from many point...


Acoustic Simultaneity

Posted by Geryllax Vu in Geryllax Vu's Blog, 28 October 2015 · 230 views

According to relativistic mechanics, two events occur simultaneously if the light from each of these two spatially separated events meet at the midpoint of the line adjoining them, at the same time. Additionally if this simultaneity occurs in a reference frame that is considered to be stationary, then the events will not be generally regarded as simultan...


Les Granges

Posted by Hawksmoor in Blog 19648, 28 October 2015 · 311 views

Toot and I had a wonderful week with Olly and Monique in the Haute Alpes. We enjoyed the magnificent dark skies, the stunning Milky Way, looking through Olly's big Dob and drawing and painting with Monique. 
We saw for the first time: The Crab Nebula, The Swan Nebula, The Eagle Nebula and all of the Veil Nebula. The Witches Broom was fantastic and t...

Ups and downs. Early Days Frustration.

Posted by GuyR in My Nexstar adventures, 20 September 2015 · 417 views

Before I carry on with my 6 SE experiences I just want to thank all of you for reading my ramblings and for your comments and PMs. It is very much appreciated. I finally have some "me" time to continue the story. 
The first thing I did when I got my box of goodies home was to unpack everything. A cup of tea came next. 
My initial impressions wer...


my new hobby

Posted by crashtestdummy in crashtestdummy's Blog, 02 September 2015 · 579 views

I've mentioned a few times that I've recently bought a road bike and have started riding a lot more and I though since I've not got anything astronomical to discuss I would do this instead :) I bought a nice giant defy 0 bike on the cycle to work scheme and spent an extra £200 swapping the brakes, chainset and front mech so it now has a full ultegra...


Stabilized videos of aircraft

Posted by GreatAttractor in GreatAttractor's Software, 02 August 2015 · 611 views

It turns out ImPPG 's image alignment (via phase correlation) function comes in handy when trying to capture a video of passenger aircraft at cruising altitudes. My rig for the experiment was a SW Newtonian 114/500 (hence the coma visible in asymmetric highlights) on AZ4 + PGR Chameleon 3 mono (ICX445) camera: 
Raw video looked e.g. like this...


Wide Field Ambitions . . . . . .

Posted by Nigeyboy in Toward First Light - And Beyond!, 21 July 2015 · 568 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...


New to Astronemy

Posted by TraderBoo in TraderBoo's Blog, 05 July 2015 · 580 views

Hi all relatively new to Astronomy I have a StarBlast 80mm from Orion without the Syn scan hand controller!!
Has anyone had any luck using Stellarium to drive the scope without the $420 hand controller??? :laugh:


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 · 884 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...


Now is the winter of our discontent made glorious summer

Posted by Andy69 in Andy's Column, 27 May 2015 · 439 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 · 575 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 · 650 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 · 724 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...


Barlow or telecentric amplifier - What's the difference?

Posted by russ.will in Musings from The Fen Edge, 29 March 2015 · 1,006 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 · 983 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...
