  1. Hi Guys, I thought I would share with you my first hand experience of the Skywatcher ED100 Pro Esprit Telescope, I have only had it a few months, but so far I am extremely happy with the results, it is so sharp and the contrast is very high. I live in a small town, Stowmarket, Suffolk, UK, where the light pollution is not to bad, but still I have to be cautious with the direction I choose to point the telescope. All my astrophotography is done from the back garden on my patio. I have had a few different telescopes over the years, but I always found myself moving more and more into astrophotography, so after some research I selected the Skywatcher ED100 Pro Esprit, as many of the other users had commented on the sharpness and contrast. As I wanted to focus on more wide field astrophotography the F5.5 speed giving 550mm seemed the right choice, I also use an ED50 Skywatcher Guide Scope with an Altair Astro ASI130mm camera for the guiding and of course PHD2 software, all mounted on my Skywatcher HEQ6 mount. Here is a shot of the Andromeda Galaxy, 20 x 30s stills at ISO 800 on my Sony A7Rii, no filters just RAW images processed with Photoshop, Stacked Mean option. I used the Trevor Jones video on his BackyardAstro You Tube page for processing DSO's and it seems to work very well. What you will see from the image is just how sharp it is, something that really surprised me when I processed the images. This has inspired me to spend more time outside in the garden to photograph more objects, plus I have recently purchased an Astronomic CLS Filter for my Sony A7Rii, so I am looking forward to using this to see if it improve the contrast. I will keep you informed. Also I am looking forwarded to trying my Olympus EM1 MK2 camera, yes I know it does not have the capabilities of the Sony A7Rii for light gathering, but it does have a really clever mode where it can stack the images in camera to reduce noise, so I will also let you know how this went as well. Best Regards Jamie
  2. Having had such a great experience with the Orion Nebula, my next target will be the Andromeda Galaxy! My Sky Safari app tells me it should be to the west northwest near the zenith. I assumed it would be visible to the naked eye but I can’t find it. Am I just not looking hard enough?
  3. One of my favorite deep sky objects in the night sky, the great Andromeda galaxy. All the processing has been done with Pixinsight. The scope was FSQ-85 with the good old unmodded Canon 6D. Around 5 hours of data with 5 minutes exposure. Hope to add some short exposures to the core someday.
  4. Messier 31 Andromeda Galaxy Distance from Earth - approx 2.5 million light years After spending ages getting a decent polar alignment, the clouds were on their way in so I only had a small window of opportunity remaining. This was my first real run with the new setup (minus the ST80 and ZWO ASI120 as i was having issues there) and I almost gave up. SO glad I didn't!! Focus was off a bit though I think and I've definitely over-processed EXIF: Nikon D5300 270mm f / 5.6 @ ISO 800 21 x 30 second subs Bortle 5 Stacked in Sequator. Very quick minor crop and global edits in LightRoom. No darks/flats/offsets
  5. I’m a beginner, I started of with a 70mm focal length telescope with a 4mm lense. With this I am able to see the moon in fine detail however all other planets appear very small. Mars for example, I can see with me eyes and when I look through the telescope it is barely magnified. My question is; What telescope could I buy at a £300-400 budget to see all the planets in the solar system and perhaps even nebula from Andromeda.
  6. Partied out from Saturday (my belated 40th), I decided to have a binocular tour in what were truly clear skies. Ursa Minor could be seen in its entirity, the Milky way was visible from the North of Aquila all the way to Perseus (and this is with one or two neighbour's lights still on!). It would have been nice to have a big scope session but work tomorrow and fatigue have conspired against me. Hercules: Both M13 and M92 stood out nicely. So I said goodbye to them for the year. Pegasus: Globular cluster M15 was barely inferior to M13. Aquarius: M2 was less clear but still easy enough to pick up. Vulpecula: Brocci's cluster (a.k.a. the Coathanger) lokked resplendent and M27, the Dumbbell nebula was very clear and bright. Sagitta: M71 came through nicely like a cross between a globular and an open cluster. Cygnus: M39 was lovely, M29 came through nicely, NGC 7000 (Caldwell 20) - almost certain. There seemed to be a paler patch of sky rather than any haze and I think I could detect a dark knot roughly where the gulf of Mexico should be. The sky was nowhere near good enough to see anything close to the distinctive shape but I am pretty sure I have cracked it. I also could see the Cygnus rift reasonably clearly. I can't remember noticing that from home before. Casseopeia: Fast becoming a favourite constellation. I managed to identify, M52, NGC 7789 (easiest of the new finds and quite large), NGC 129, NGC 225, NGC 457, M103 and NGC 663 (all open clusters). There were many other named parts of the constellation I absorbed but did not note. Andromeda: M31, the Andromeda galaxy was as big and bright as I have seen it. Definitely managed M32 in binoculars for the first time, possibly M110 but am far less sure: I have only managed with my scope a couple of times. Triangulum: It was not that high in the sky but M33 was no problem at all. And to think I once had problems with this one, I could look directly at it in binoculars. Perseus: NGC 869 and NGC 884, the Double cluster looked beautiful given it is nowhere its zenith yet. M34 very good too. The best bincular session for a very long time indeed. Great stuff! __________________________________________________ ______ Observing Session: Sunday 16th September 2012, 21:10 hrs to 21:55 hrs BST VLM at Zenith: 5.4 - 5.5 New - Revisited - Failed
  7. I decided it was about time I had a go at Andromeda, so with 2 clear nights this week I've managed to gather just shy of 7hrs worth of colour and Ha for the star-forming regions. I've had a couple of realisations while working on this: It's MASSIVE! This is a 2-panel mosaic and it still only just fits! It's a real challenge to process. Even with a fresh set of decent flats, I had real trouble combining the 2 halves. Don't think I've quite got it right yet. It's one of those targets where I think, if I started again from scratch with the processing it would look completely different each time! I might try again some time, as I'm not happy with all aspects of the image... Also, I would like a bit more colour data for the faint areas. Colour: 2 x 26 x 300s Ha: 2 x 7 x 600s Camera: 450d, modded Scope: Skywatcher 150PDS Mount: Vixen GP (getting long in the gear tooth now!) Any tips on processing M31 would be greatly appreciated! M31 was actually the first DSO I ever attempted capturing on camera. At least my new version is better than that!

  14. Whilst I was at work today, Parcelforce delivered 2 large boxes and a little jiffy bag. The two boxes contained my first scope- Sky watcher explorer 150P complete with 10mm and 25mm eyepieces, a X2 Barlow and my EQ3-2 mount. The jiffy bag was my planetary and moon filter set. I unpacked the gear and spent some time setting the equipment up then had dinner. As soon as I had eaten, the excitement got the better of me and I was outside where the cloud had cleared and the Moon was high and bright. I aligned the mount with Polaris and used the moon to centre my finder scope with the main scope. I then set to having a look at our nearest neighbour. Wow! I am hooked. I spent a good 40 minutes swapping between eyepieces and the Barlow, getting a feel for how they perform and the relative merits of each combination. Having fallen back in love with the moon, I decided to try for a DSO and, utilising Starlight for guidance along with some remembered tips from on here over the last few days, I located the rough vicinity of Andromeda. I aligned the scope using the finder and then started to do a bit of 'fishing'. After a few minutes of using the slow motion controls on the mount, a hazy blob came into view. I centred it and, again falling back on advice from here, relaxed into looking through the eyepiece and averting my gaze slightly. Before I knew it, the hazy blob had resolved into a milky cloud with a brighter heart. I was looking at my first ever galaxy! Another 40 minutes exploring the effects of the optics on my view of M31 and I then had to call it a night. I dedicate this report to all who have advised and guided me since my arrival in the lounge. Thank you all! P.S. Is there another smaller fuzzy feature in close proximity to M31 (i think right and slightly up as my view moved so slightly left and down in real orientation)? If so, I may have seen this also but it could well have been tired eyes playing tricks.

  16. Last night there was no moon and the sky was pretty clear. I decided to take a bright object and experiment with dithering. (APT and PHD) I had some trailing in the end of the session and had 20 subs of 150s each to work with. I was amazed what I was able to get out of the data with just 5 flats.darks and bias frames.. Actually its one of my best images I made since I started this year with astrophotography I am with it.. 20x150s ISO 800 with Baader Neodymium filter

  21. When everything goes well and you are not pushed for time or work/family commitments this hobby is the most relaxing and interesting hobby there is. Last night I finally had the chance to use my star adventurer for a full evening instead of racing against the clock or trying to work around a cloud or some other inconvenience. I decided to target andromeda as it was the easiest and from my back yard as it was perfectly positioned and also I wanted to give my star adventurer a good test. I set it going on a 200mm lens for 1 minute exposures at 1600iso. It was great. I just set it going taking pictures and sat back in my camping chair taking in a very rare beautiful clear sky by eye only. Its easy to forget just how beautiful it all is when only observing by eye as we get draw in by more tech to aid us. I think this might just be my new observing technique whilst also getting some great pics or maybe get a pair of binos. Anyway this was andromeda which is by far the best I have ever taken. I also took pleides and had a go at m33 but that didnt work. I think I missed the target
  22. From the album: Deep Sky Objects

    M31 Andromeda Galaxy, taken using LRGB filters. No Moon, but heavy light pollution and a battle with dew. Plenty of tracking problems, the LX90 mount is showing the effort of tracking is this much equipment with a lot of errors. But I'm relatively pleased with the result. I have fine tuned the Orion ST80 and the end results seem very much improved over previous efforts so it looks like the hard work has paid off. The astrobin link if you want more information is: http://www.astrobin.com/238758/ Let me know what you think.
  23. Having another crack at Andromeda tonight, my last chance before the weekend, and I've got opportunity to be in a dark skies pretty much (going by local light pollution data maps.) I've noticed that my last couple of attempts I've totally blown the core. Trying to find the optimal ISO to shoot it at as I've been doing 10000 and 12800 in heavy light pollution. Working with a Nikon d5300 at 200mm and f / 4.8, which I know is far from ideal but for now that's the kit I have to work with. Doing 2 second exposures with darks and offsets. Any quick advice would be much appreciated
