  1. Hi guys Pretty happy to inform that I succefully debayered my first ever 550D and...oh boy does it perform! This is just a little over 2 hours quick and dirty processing (14x10 min. @ 1600 ISO made with the mono 550D, this camera is still assembled with the frontal LPF1 original IR cut filter and has no cooling, I'm studiyng a way to apply cooling and I will do it soon The image was captured on my extremelly light polluted back yard with the mighty SW ED80 with 0.8 reducer (480mm f/l) @ f/6 and it's a stack of 14x19 min. subs @ 1600 ISO (13Cº on the exif info). The sensor still has quite so

  2. Had a great day off putting this together and sorting myself out with it. I haven't looked through it yet but so far I'm over the moon with it. I had to set it up indoors because of the weather. Here's a few pics.I took some close ups of bits so you can see a bit more detail than just the final version. I set everything out on the Dining Room table first The mirror box came like this, cotton wool between the mirror and the cover, & cotton wool pads protecting the mirror by the clips. It was wedged in the box with little foam wedges. There are two collimation wheel bolts like the one

  3. After many, many attempts and nearly giving up I finally saw the Horse Head nebula and I must say it is a great challenge and test of sky conditions. One of my favorite sites, the quarry, was 10 deg colder than home- I lucked out and hit a nice bubble of transparency @ 21.2 mag and -33c. The 25mm TV plossl gave great performance on the Veils "thin thread" earlier on in the season so I knew the EP was up to the task and my Astronomik filter showed other faint nebs well. Still, I had no luck so many times, I had accepted I may never see this object-what a surprise when I saw IC 434 under Alnita

  4. I have finally started processing various projects gathered at the end of last year. This is the first of them, M45 - The Pleiades, gathered on 23rd and 24th November 2014. 80ED with reducer, QSI 683-WSG and Baader Filters. RGB = 12 x 300s each L = 23 x 600s Total integration time = 7hrs 50 minutes It should have been 24 L subs to take it to 8hrs, but one sub was wrecked by a bright satellite trail that wouldn't come out in the stacking. I use Nebulosity3 on the Mac and used the Standard Deviation Filter at 1.5, but it was still too evident in the stack. I often see that people can remove sat

  5. Well after a long time imaging I have decided to call it a day and sell off my stuff to move on to other interests but I wanted to say a most sincere thank you to all my friends that I have met on this forum over the past 5 years. This forum is such a great place to learn about the hobby and meet others and dont think I would have achieved half of what I have done with out the stargazer lounge and all the great people I have met on here. So thank you from the bottom of my heart to all of you. Im still going to carry on my observation of the night sky with my local astronomy group but the imagi

  7. Hi fellow SGL peeps. I have been under the radar for a while as my work laptop was replaced and all my software was installed on it. It has taken me about three months to re-install everything. I have decided to go down a slightly different route this time. I have purchased a samsung netbook (2gb, atom 1.6) for capture, which I have setup with APT, EQMOD, PHD and AT. For processing I have installed DSS, Photoshop CS5 and Image analyser on a virtual machine using virtual box (pretty cool free piece of software from Oracle.) So setting everything up and getting it all to work has been a journey,

  8. Hello World As a novice to the sport, 2014 was my first year in, so I have started with a very budget kit. These are shown on the bottom of each image. General kit bag consists of a 127MAK reduced to F6.7 and a 80ED reduced to F4.5. These light scopes give me a range from 360mm FL through to 1200mm FL. I run these on a old EQ5Pro via trusty EQMOD, which is corrected by a 50mm Finder guider and a QHY5ii. My aspirations for this year ... still in new years resolution mode ... is to get a mono CCD. (Yes I know a CCD cost more than all my kit put together, but to progress it must be done.) He

  9. It's been a while since I posted in the Lunar section so considering the Moon is the only object iv'e been able to image recently then this is an appropriate time. We had some calmer weather on the 29th of December (and the 30th) where the seeing was fair to good for a time from my location so I made the most of it and captured quite a bit of data over the two days (around 200Gb). This has taken quite a while to work though!! These are two small mosaics (3 panels for the Apennines and 4 for Aristoteles and surrounding region). Hope you like them and thanks for looking. Pete

  13. I finally had a few hour gap in the clouds and couldn't resist capturing this lovely comet! I was struggeling with the color balance, as it kept falling over to the cyan/blue side, while as far as i know it's supposed to be more green(?). I tried to correct it, but not sure how far off i am, and wich verson looks best? Either way i'm quite happy with it. Taken with the 550D and the Explorer 200 PDS. 40x 30 sec @ ISO 800, flats and bias added, no darks. Stacked in DSS, processed in PS.

  14. Evening all I had the genius idea to try the Iris in wide-field. Not normally and LRGB person but went with it - likewise little experience with the dark nebula processing. After many attempts I finally got subs flat enough to stack (gradients in RGB are not pleasant!). Found the target very challenging but think it is starting to take shape. Ideally I would have used less noise reduction but seeing was poor last Saturday with a great deal of cloud dodging. About 5 hours data 3 of which Luminance rest RGB. Comments and critique welcome as ever. If anyone is an expert in processing that da

  15. The day started with heavy cloud but cleared to reveal beautiful sunshine.... just as I started teaching at 9.30. The solution? Take the students out into the car park with me! It was a great success, and to my great surprise, the seeing was pretty good, even though it was not long after sunrise. The second image is with the 3X Barlow and hence is rather soft,

A large coma, a hint of a tail, and a subtle hint of green shading .... This is the first comet I've ever seen so clearly (as a starry-eyed teenager I did catch a glimpse of Halley's Comet)! I'm really looking forward to more views of Lovejoy as it continuous to brighten Along with lovely views of the Pleiades, the Hyades, the Orion Nebula, the Double Cluster, and winter star fields .....

  19. So your Astromaster has a focal length (as advertised) of 650mm (distance from mirror to where light is focused) To work out your magnifications, divide the Focal length (650mm) by the size of the EP (also in mm): 650mm / 20mm = x32 magnification 650mm / 15mm = x43 mag 650mm / 10mm = x65 mag 650mm / 6mm = x108 mag so what the barlow does if x2 is to take the 650mm and double it. Then do the math again: 1300mm (double the effective focal length) / 20mm = x65 mag 1300mm / 15mm = x86 mag 1300mm / 10mm = x130 mag 1300mm / 6mm = x216 A lot of people just double the initial magnification though ;-)

  20. The only real victory here is I guess that it stayed clear all night and what a clear night it was. My first 7 Planets, The Moon and a naked eye comet, that can't happen too often? In the order of view, Venus, Mercury, Lovejoy Neptune, Mars, Uranus, Jupiter, The Moon, and Saturn which is not as low as I thought it may be. Even managed some sleep between Jupiter and The Moon.

  22. Thank you everyone some time off fishing rather then imaging will be a nice change and I can always go imaging at my local astro soc so its not that bad really. If any one out there would like to know what I think 5 years on it would simply be this, Astrophotography is one of the most wonderful hobbies I have done and although it can be very frustrating at times the rewards far out weigh the problems. When I look up at the night sky now my mind can picture clearly all the wonderful Nebula and Galaxy's cluster etc that are up there hidden in the stars, totally priceless to have that experience.

  28. Ok, Polaralign (JD version). Its pretty easy, and you dont need to be concerned with transits etc. And its good enough to PA for an imaging run lasting all night with no dropped subs. A quick runthrough: 1) Enter your Lat/Long, this will be the only time you need to do it. It will then display where polaris should be at that particular time (takes time from your system clock). 2) Looking through your polarscope, rotate the RA axis slightly so the crosshair in the polarscope is like the crosshair on polarfinder (like this: +). Take a moment to get that right. 3) Now use the alt/az adjustment bo

  34. It has been fabulous watching this comet over the last couple of weeks. Slowly getting brighter and higher as it continues its long journey. Easily the best comet since my full return to the world of astronomy. 18x120secs with my Canon350/200PDS. I did hope for a little more detail in the tail, but seeing the images on here its looks about the same as most of them. Also really should have done some calibration frames, but its been a long road getting everything working on the new laptop (windows7)

  35. There's nothing quite like the joy of a Dobsonian - I've had one nearly a year and am now a convert. I feel your pain with the dark site thing - M31 in suburban London is a blurry let-down, although it is quite cool in and of itself. Transparency can yield surprises though - M32 is an easy one to pick out and a couple of times I've even managed to find M110 from the park. Best things to look at under light pollution are the planets and the moon (As you've found out) and planetary nebulae which tend to have low surface brightness. Oh, and invest in a UHC filter - a real game changer. It brings

  39. Nigel, First off a good selection of scopes for visual use (and the HD versions are imaging ready....though see below). The Edge 800 is a nice scope (and not as little as you think). It has done well for me in terms of imaging the lunar surface, and just started to have a go at planetary. Both lunar and planetary use small CMOS cameras to take lots of frames and then you stack them (choosing the best ones). Both the 800 and 925 are great for this aspect: What can the Edge800 do? (when you also have a CMOS camera) so this is with the 800...the 925 would get you closer....: However when using a

  41. Hello Simon - you are probably not far away from me! There have been a few threads on here about astigmatism and observing. I started one recently re the possibility of using contact lenses and, in fact, I have just returned from an appointment with the optician. I have astigmatism in both eyes but one (the right) is worse than the other. I also need glasses for reading so I have varifocal lenses. But for some reason and despite everything that I have read about long eye relief etc, I simply cannot get used to using glasses to observe either with binoculars or a telescope. I always feel that I

  43. Well done! I waited what seemed like half a lifetime to see Halley, expecting wonderful things, and in the event I saw nothing at all. And to this day I still remember the massive disappointment of fruitlessly scanning the night skies for Kohoutek in - what was it - 1974 or thereabouts? By the time Hale-Bopp came along I had reached such a level of cynicism about comets that I nearly didn't bother looking. But that, in the event, was a lovely comet, so all was forgiven. And thankfully Lovejoy was, I think, never predicted to be on the scale of those others, so frankly any view at all has been

  44. Looking at your image the stars in the middle and on the left hand side do look nice and round, the problem is the right hand and to me this does not indicate a fault with the optics of the scope but probably a tilt of the camera sensor to the optical axis. You ought to investigate this first before jumping in for a flattener that may or may not work with a Petzval design. A.G

  45. I agree with Russell. That Konus is undermounted and does not look to be in very good condition. Not good use of 350 Euros I feel. I'd probably avoid it even if it was half that price. I've owned two Konus scopes and they were clones of Skywatchers and decent scopes but they also have some not so good scopes under that branding I'm afraid.

  46. I can't see that being a good buy. The mount doesn't look meaty enough for a 10" newt and by the time you've bought the missing slow-motion controls/motors, new tube rings, etc, you'll be back to 500E easily. For 500E (plus shipping), you can get a GSO 10" Dob brand new from TS is Germany. I've even seen Skywatcher Flex-Tubes going in the UK for £500/600E (ish) and with a bit of patience, a 12" solid tube could be easily found, be it GSO or SW. Russell
