The Celestron 14 is mounted on a Paramount ME that I have been using for about 10 years now - you can see that it is mounted on a tripod so is a portable set up. I still manage to transport it on my own and set it all up even though I have just turned 70! It will run for hours centering galaxies in the 12 minute field even when tripod mounted.
Wednesday, February 18, 2015 at 8:08AM I managed to get an image this morning of the 14th Magnitude Comet 32P/Comas Sola in the constellation of Leo.

Monday, February 9, 2015 at 6:57AM I used telescope T9 at Siding Spring to image this open cluster using V and B Filters. Telescope T9 is regularly used in Hubble Space Telescope support missions. This cluster was discovered on 15th February 1836 by John Herschel, the son of William Herschel. The stars are generally around 12th Magnitude. The cluster is approximately 5' across. The field of view of telescope T9 is 13.6 x 20.4 arc-mins. The cluster lies at a distance of 2650 Parsecs. (Ref 1) The bright foreground star is HIP 38197 with a magnitude of V =7.95 and B = 7.80 so is slightly brighter in the blue. It lies at a distance of 1,716 Light Years which is 526 Parsecs so it lies at about one fifth of the distance of the cluster from us.

Tuesday, February 3, 2015 at 7:11AM This is the view looking south tonight at 10 p.m. local time from the latitude of my location in Lancashire.
Chart courtesy of Software Bisque
The panoramic horizon is of my view in Spain last year - unfortunately not what I see now in a town in Lancashire! Gemini is in the south with Castor and Pollux approaching the meridian line. Castor will be the first to get to the meridian at 22:51 followed by Pollux at 23:02. At 10 p.m. Castor is at an altitude of 67 degrees and Pollux at 63 degrees.
The constelltion of Gemini is shown in a closer view below.

NGC 2331 is an open cluster in Gemini with a diameter of 19 minutes or arc. Uncle Rod from Possum Swamp observed this in 2009 at Chiefland Astronomy Village in Florida but didn't seem to think much of it! Several descriptions of it are given in the Deep Sky Observer's Companion.
Monday, January 26, 2015 at 12:10PM I have just set up a home based "Cloud" service that allows me to back up everything from my various computer devices to a special type of 2 TB hard drive that plugs into my router. My main laptop now automatically gets backed up onto this on a continuous basis through my wireless network. Obviously the one drawback is that if my house burns down the drive goes with it. The advantage is that I buy the drive once and don't have to pay a company recurring fees for external service. However my Dropbox account (only a free one) links to the cloud system as a device so if I want to use that as well I can.
That is only part of it - it also backs up my photographs and music to the home cloud from my PC, iPhone and iPad. Now if I want music I go onto my iPhone (or any device), run the iPhone cloud App and select the music from the cloud drive! Centralised music. I also have a bluetooth speaker so I usually just use my iPhone with the cloud, set it to bluetooth on and play the music.
This is not just from the house! Anywhere I have internet access I can access anything from my cloud drive - so if I am in Spain and want to show photos from my cloud I can do so!
The same applies to WORD Documents and PDFs etc - for example If I am working on a WORD document I can drag it from my PC to the cloud drive and immediately access it from my iPhone or iPad.
I found that it is an excellent way of managing PDF files. I have subscribed to the PDF only option for "The Astronomer" magazine for some time now. I usually forget to save them or save them somewhere I cant find! I have just stored (all 12) 2014 issues on the cloud and can now go onto my iPad(wherever I am) , open the cloud app and "The Astronomer" folder and there they all are. PDF magazines are ideal for reading on the iPad. I will work back through the issues storing them when I can.
I also now subscribe to the online only editions of "Sky and Telescope" and "Astronomy" US based magazines. It is very straightforward to save these as PDFs and I now read those on my iPad as well.
If you are a BAA member and have registered on their website you have access to any issue of the BAA Journal online as a downloadable PDF. A word of warning - they are all there from issue 1 which was October 1890!! At 6 a year that adds up to quite a lot. However I now have a BAA Journal folder on my cloud!
I have copies of astronomy magazines going back to the seventies so a large chunk of my house is packed with them - I may soon be thinking about selling them off!!
Monday, January 19, 2015 at 11:04AM Satellite scores a bullseye! How to ruin an image of NGC 4459
Saturday, January 17, 2015 at 5:04PM This is NGC 4349. Although it was the 17th January 2015 here it was 04:51:38 in the morning of 18th January in Siding Spring. It was a 300 second exposure. It lies at a distance of 2176 parsecs.
NGC 4349 North is up and east is to the left
This is the data from the plate solution
NGC 4349 is arrowed.
This is where you find NGC 4349. If you look closely you can see the actual image to scale at the chart position marked.

So NGC 4349 is situated in the southern consteallation of Crux which is The Southern Cross.
Wednesday, December 31, 2014 at 9:15AM I took this image of M37 yesterday using the telescope T11 in New Mexico.
Tuesday, December 30, 2014 at 7:30AM I received an email this morning from the American Association of Variable Star Observers (AAVSO) telling me that the AAVSO Photometric All Sky Survey (APASS) catalog had been updated yesterday so that it now contained 50 million stars with measured photometric magnitudes. In the past it has been difiicult for amateurs wishing to measure the photometric magnitude of a new or variable object because of the unavailability of comparison and check stars in the same field as the target object. APASS greatly increases the chance of being able to do that so is potentially a major step forward in advancing science. I was working on the open cluster NGC 2477 and imported APASS stars within a 3 degree diameter around the cluster. I set up database using these APASS stars and added this to the SkyX software. The result was over 8000 APASS stars and the resulting image with a 3 degree diameter of these looked like this!
The individual APASS stars are labelled and a path is shown in blue to move the telescope from APASS 1 to 8177 - if I wanted to do that. This illustrates the vast number of comparison stars that are now available to the amateur photometrist.
