  1. Hi, i'm looking to by the 127 Mak next year for Moon photos, i awtched a short review of the scope and the guy briefly mentioned that AZ mounts may not be the best for astrophotography. He didn't go into it at all, what are the reasons for that? I've not even held a proper mount so only have a vague idea how they rotate. Happy new year
  2. Hi folks, I captured a few shots of Mars and Saturn in the early hours of Monday morning. Unfortunately the Saturn images were waaaay too dark and dim to be useable. Even though they looked bright enough on my laptop screen when I play the avis back now, I realise I needed to bump up the settings significantly before I’d be able to create an image recognisable as Saturn! So anyway, boosted by my attempt earlier in the month with the 2x barlow, I thought I’d have a crack with the 3x. Truthfully I was pushing my luck as the seeing was pretty poor, and very few frames actually captured the round disk of Mars. I believe this explains the ‘mist’ of noise around the planet in the images from both cameras! When I ran the DMK21 version through Registax, I noticed a white splodge on the upper right section of the planet itself. Bit frustrating I thought, but then there’s streetlamps everywhere here and I’m using a £9.99 3x barlow of no known brand, so these things happen. But when I processed the SPC900 version taken about 10 minutes later, it cropped up again, and appeared to have moved a distance relative to the other features on the images, in line with Mars’ rotation. Any ideas? In comparing the cameras, I think these confirm the suspicions I’d formed from the Jupiter images I'd managed earlier in the year, that this camera is very strong in good seeing conditions, and picks up a lot more detail in good seeing than the SPC900 does. However, in poor – average seeing, the SPC900 actually does just as good a job really. I guess ultimately any equipment we have is going to be limited by the atmosphere we have to look through... Can't wait to have another crack at these two fascinating targets, hopefully in better seeing, and when I get my settings right!
  3. From the album: Imaging Jupiter

    Jupiter - 127Mak-Cas - F12 - AS!2 - 840 Stack - Denoise / Sharpen - Histogram Stretch - RGB Rebalance - Midtones adj This was taken on the 22nd at about 2C did about 1400 images, but due to clouds and poor seeing has been reduced to 840. I read a great post which helped me a great deal in getting a better image. http://stargazerslounge.com/topic/184821-beginners-guide-to-stacking-planetary-images-with-autostakkert2/?hl=+registax (Thanks James) Going to continue processing and see if I can get this better.

Powertank was bought at christmas and has only been charged once The star diagonal got dropped and the silver insert (the bit that you put the eyepiece into) that screws into it became slightly loose in the threads so I repaired it by putting superglue on the threads and screwing it back in. It is held solid now and no glue is visible and all the eyepieces fit perfectly. All instruction manuals and tools still in bag. Non Smoking Household £400 ono reduced Location Bolton, North West England. Collection or I can do local delivery in person. I would prefer this as postage would be expensive also the risk of damage in transit. If needed then I estimate around £15 due to size and amount of items if sent by courier.
  5. Hello there! If someone has a 127 mak, in great condition (and reasonable price), that doesn't use/want anymore, (and he's/she's willing to post to Europe, at buyer's cost) can surely drop me a message! thanks!!!
  6. Hello stargazers, I've been stalking this forum for a good couple months now in my search for a telescope. My main focus will be the visual observing of planets and DSOs. I like photography might plan that later if possible (i'd like it to be). The skies where i live is somewhat polluted but not so much. I can easily spot most constellations with the naked eye if my drive my car on a hill outside the city. I was thinking about one of the models below. I'd like the get the best bang for the buck and minimize the risk of being disappointed and then wanting a more expensive tube later on. I'd like to learn the sky by heart thus steering clear of a GOTO for now. I'm not going to buy anything right now because I'm putting some hard earned cash in a pair of binos first. My options: (but I'm open to any and all suggestions!) Skywatcher Skymax 150 PRO €569.37 + Skywatcher EQ5 Deluxe €269.02 Objective Lens Diameter: 150mm Telescope Focal Length: 1800mm (f/12) EQ5 because it's a good stable mount that I basically can keep using if I ever upgrade the OTA Skywatcher Skyliner 250PX Dobsonian €463.49 Diameter of Primary Mirror: 254mm Telescope Focal Length: 1200mm (f/4.7) Celestron Omni XLT 127 €647.16 Objective Lens Diameter: 127mm Telescope Focal Length: 1250 mm (f/10) Skywatcher Skymax 127 OTA €274.42 + Skywatcher EQ5 Deluxe €269.02 (Or EQ3-2 for €442.96) Diameter of Primary Mirror: 127mm Telescope Focal Length: 1500mm (f/11.81) I might also get the less stable EQ3-2 for a 100 euros less. But again, the EQ5 is a good investment I believe Skywatcher Explorer 200P EQ5 €504.55 Diameter of Primary Mirror: 200mm Telescope Focal Length: 1000mm (f/5) I got all the prices from FLO. Some questions that I still have: (thanks for staying with me so long) - Would you be able to see some DSOs with anything up from f/10? - Is a dew shield necessary if i live in the Netherlands? - I know its been asked a lot but what eyepieces would you recommend? FLO recommend BSTs. Then again which lengths? I thinks thats all for now:) Thanks so much for checking this post out. Clear skies to you all!
  7. I’ve been enviously watching the detailed Mars images appear here on SGL from the 8+ inch scopes, when my previous efforts over the last couple of weeks have been absolutely awful. You wouldn’t have known it was a planet, it just looked like a small fuzzy splodge, through the SPC900 or the DMK21! I’d been starting to wonder whether that was all I would be able to get on Mars, and I’ve been struggling to reconcile that with the view I had of Mars a couple of years back through the little Mak, where I could see bags of detail (by Mars standards anyway! ). Anyway, just after midnight I set the camera up to run on Jupiter and the moon for a while, before I realised I was about to lose Mars behind a huge tree for an hour or more, so I swung round and had a crack at it. Thought I could see a hint of detail, just a dark patch on the right hand side when I was trying to find the right settings, so figured I must be close. Did 3 runs with different settings, praying the dew didn't get any worse, packed up for the night and came inside. OK, so in hindsight, imaging the ‘Red’ planet in mono means that a certain amount of the wow factor here might have been lost, but I was dancing around like an absolute loon when this popped up in Registax… Far from perfect I know, but a huge ‘personal best’ for me on Mars. The seeing wasn’t great here either, though it wasn't terrible like it has been recently, though most of the frames looked real fuzzy. This gives me some hope that I might even be able to improve a bit more over the coming weeks. This was 5 minutes at 30fps, Exposure -6, Brightness 15, Gamma 97, Gain 809, with a stock Skywatcher 2x barlow, run through PIPP and then stacking the best 20% in Registax. I’ve been on a high ever since! Picked up a couple of reasonable lunar shots as well – I think the DMK21 (which I actually picked up in FLO’s clearance last year, but have had very little time / clear nights to use it) will be amazing on the moon once I get my settings and focus right. Can’t wait for Saturn to rise a little earlier – I tested the camera out very late in the Saturn season when it first arrived last year, and it outperformed the SPC900 by a mile, so even though Saturn isn’t going to be particularly well placed for us this year, I’ll be ready for it!
  8. I need some advice on how to get the detail up and the size of Jupiter. My goal is to get to a postcard print worthy imagine (for personal use.) I am using a 127mm Mak (F11) on a EQ5 Pro and imaging using a QHY5LII (Colour) Current progress - Some detail but lack size / detail and colour for my print. Some questions that I need advice on: Jupiter rotation: I have heard that you should not exceed about 90 seconds? (I just use a image limit 1000 not a time limit @ 5FPS = 3+Min) Barlow: Should I increase to F22 or F44? (Currently I stick to native F11) Filter: What is the preferred Filter to use? (I sometimes use a moon filter.) Format: Raw format and debayer in PIPP or Registax? (I have real problems with Raw so I capture in BMP at 800 by 600 or larger for moons.) Once I have captured the raw data based on your advice. I will process and repost to get more advice.
  9. From the album: Imaging Jupiter

    First image of Jupiter for 2014. Taken on 04th of Jan, at about 4C Nice clarity on this one, transparency was excellent, but occasional clouds to be dodged.
  10. From the album: Planets

  11. Hello Please find my first attempt at Saturn. Advice needed on how I can improve capture and processing. My adventure started at 6:00 am this morning taking on -2C ice and frost, to capture Saturn in the South before sunrise. The transparency was good though and the stars looked really crisp against the still dark sky. (Exciting!) I managed to capture two run of 39000 images at 65FPS at 15ms exposures, raw mono data. Using my 127mm Mak (1500) with a 2x Barlow to get it up to 3000mm Anyhow just finished processing, process followed was. (Was done in a bit of a rush.) Dark Frame 10000 stack at -2C Reference Frame AS!2 - 25% using 4 quality setting, sharpening and mix in raw 50%, REGISTAX - Wavelets and gamma adjusted, Histogram stretched. Main Frame AS!2 - 50% using 4 quality setting, sharpening and mix in raw 50% REGISTAX - Wavelets and gamma adjusted, Histogram stretched and increase size to 1.5 I have been a bit aggressive with my wavelets and placed this on a black background, with a bit of mid-tone adjustment. It feels a bit blurry and very yellow, not much in the blue channel, is this normal? Do I need I need to up my FL to from 3000 to 4500? Lack detail for +-20000 images, should I up the exposure and reduce the images? I am being overly critical for my equipment? Thanks for the feedback, appreciate it guys.
  12. From the album: Saturn Journey

    First image of Saturn taken at 6:30am on the 5th of Jan 2014. Second round of processing, this time I have created a luminance layer and enhanced with a Blue Filter.
  13. From the album: Imaging Jupiter

    Jupiter - EQ5Pro, 127Mak-Cas - F12 QHY5l - Colour +-1000f (1.2 Gb 1min05') -7C Pipp, AS!2, Registax6 (75% Stack, Wavelets, RGB Align, Contrast) This was taken on the 28 Dec 13 at about -7C did about 1000 images
  14. From the album: Imaging Jupiter

    Jupiter - 127Mak-Cas - F12 - AS!2 - 750 Stack - Denoise / Sharpen - Histogram Stretch - RGB Rebalance - Midtones adj This was taken on the 22nd at about 2C did about 1400 images, but due to clouds and poor seeing has been reduced to 750. I have sacrificed some detail on the planet to include the moons, think it is better like this though.

    Have had a play with the 3x Drizzle
  16. From the album: Saturn Journey

    First image of Saturn taken at 6:30am on the 5th of Jan 2014. First round of processing, will reprocess again later, see if I can improve. Seeing was poor, but transparency increased through the morning. Caught this image just before sunrise at 65FPS, got 39000 images.
