The Sculptor or Silver Coin Galaxy ( NGC 253 ) in the Sculptor constellation - re-processed from the original subs The Sculptor Galaxay ( NGC 253 ) ( Please click / tap on image to see larger and sharper ) .................... The Silver Coin Galaxy ( NGC 253 ) in the Sculptor constellation ( aka the Silver Dollar or Sculptor Galaxy ). Caroline Herschel in 1783 was the first to recordthis bright ‘nebula’ in an area of the southern sky that Nicolas de Lacaille had called the “Apparatus Sculptoris” or “the sculptor’s studio”. Whilst relatively close to us compared to the billions of far more distant galaxies in the Universe, the great size of the “Sculptor Galaxy” and the huge distances involved are still hard to comprehend. To put this into some perspective, the light that is just now reaching one edge of the great disc left the opposite edge when the Earth was in the grip of last great Ice Age 70,000 years ago and the light we now see has been travelling towards us for over 11 million years.

Does anyone have a link to a user manual for the new Synscan App? I currently use the hand controller to set up my scope and then use SkySafari to control it via a SkyFi module. If I can replace the hand controller with the new wifi module and App then I can setup and control the mount while sitting inside my roll-away shed. Before I order the new Skywatcher wifi module, I want to find out to what extent the app is a full implementation/emulation of the hand controller. In particular, from the screen shots and the greyed out buttons on the app, I cannot tell if it is missing any of the functions I use on the hand controller. Some of the important ones I need are: - Park to custom position - Auto Home ( including calibration ) - Pointing Accuracy Enhancement - Periodic Error Correction Does anyone with the App know if it is a full implementation of the hand controller? Cheers Mike
I've been toying with te idea of getting the skymax 127 for a while, and I've noticed the picture has changed now to one with a rather unsightly green dovetail. https://www.firstlightoptics.com/maksutov/skywatcher-skymax-127-ota.html After seeing this video, I noticed that the older one says Schoot glass on the side, and came with 2" diagonal. The newer version seems to have a 1.25" diagonal now and doesn't have the label on the side. Can anyone confirm this? Would it not using Schott glass anymore have an impact on quality?
I bought this at the start of the year with some xmas cash i had, and its been great, but recently ive had back issues from the gym, and my neighbour has installed a load of lights in their garden, meaning i now need something a bit lighter and more portable so i can go elsewhere to observe. It is a used scope obviously but as far as i know its in good condition, all the GoTo system works, ive never messed with any screws for collimation etc as i dont know how to do it lol, the previous owner assured me the mirror has never been cleaned or touched, and its been kept in my garage under a telescope cover, the middle cover, the EP cover, and the elasticated end cover are all with it. The previous owner has fitted wheels to the base which does make it moveable, but i thought that by pushing it up the street it might affect collimation so ive only ever pushed it a few feet and then lifted it out of my garage. Also fitted is a counterweight, I found this really helps. It will also come with a light shroud, pretty sure its the Astrozap one, and the original EP's. As far as im aware it was the previous owner who added the GoTo handset to this scope, im pretty sure it didnt come with it from new, it had a smaller controller with no display which will also come with it, it all works fine ive never had a problem with it, the only small issues ive had were all user error as this is my first scope, wrong date and time etc Being reasonably new to astronomy im not quite sure what to price this at, and it would be collection only im afraid, from St Helens, Merseyside. I still have the original boxes if required but obviously the base is built up so wouldnt go back in the box. Pics to follow soon Looking on eBay i can see two 250 dobs priced at £400+, neither are the flextube or have GoTo Price reduced to £500 as id like a quick sale, ive bought a new scope now and need to the money for a few bits for that before i go away on holiday
