  1. After watching a youtube clip from Astronomy Shed, I installed a small cooling fan on my SW 150PDS. I had the fan and a piece of black acrylic lying around, so cost was € 0. Simple design: cut out the acrylic. Make holes for the fan, switch, screws and cables. Cut out slots for the collimation screws. Stick some velcro on the back, and presto. Hopefully it will improve the cooling and decrease tube currents. The black acrylic should also (slightly) reduce the risk of light leakage.
  2. I am currently using a Starmax 127 Mak which has a lot going for it as a compact travel scope. But it has a horrible focuser and a slow F-number. I am thinking of moving up to the Skywatcher 150pd-s Will the extra 25mm or so diameter give me a boost in visibility and usability (cool down time, focussing) as well as being a bit more astroimaging-friendly (speed)? I shall use it on an HEQ-5 so I think this should not be worried by the weight of the OTA even in imaging mode. David Opinion seems to be divided on the compatibility between this mount Ang the larger 200pd-s. Is this correct?
  3. I cannot emphasise enough my current feeling of happiness. For weeks on end, I've been looking for a seller in Japan that offers the HEQ5, but the effort was futile. Until now, that is. FLO (First Light Optics) ships to Japan! They really do! (Well, I will have to add 200£ to the mix, though). What makes matters better is that by the end of the year, I'll be able to afford the HEQ5, a good (F4) guide scope, a autoguiding camera, AND possibly a Coma Corrector! But then again, I'm thwarted by a question my beginner brain cannot answer. Assuming I have the HEQ5 perfectly Polar Aligned (Sharpcap Pro FTW) and I've balanced correctly (that biasing rubbish), what kind of subs will I be expecting with roughly 7-8 kg on the HEQ5 total? Clear skies, Leon.
  4. I have a GPCAM Mono and am looking to get an OTA plus mount suitable to go on my 150PDS. I'm aware of the ST80, but it's relatively heavy so was thinking of something like the QHY Miniguider kit (expensive?), or Altair Astro's '60mm Miniguider with Autoguider Webcam focuser, tube rings, multi-purpose base' kit (although it has nylon-tipped bolts to hold the OTA). 50mm OTAs are on the short side in terms of pixel ratio (the GPCAM+OTA/150PDS+Canon 50D), hence looking for 60-80mm. Or, should I go with an off-axis guider instead?
  5. Hello, I hope this is the best place to post this... I recently acquired a Sky-Watcher Explorer 150P DS and an HEQ5 Pro to go with it and couldn't find that much information regarding what was actually in the boxes, to know if I needed to buy anything else, etc.. So I made this unboxing video so that people can actually see what the boxes contain and get a bit more information regarding the kit. Bear in mind that this is my frist unboxing video and that I don't have any intention of being a know-it-all... I just want to share information with people out there... If you find these helpful I'll continue to do these (since I'm waiting for the arrival of an eyepiece and a Barlow, otherwise I'll just stop... Cheers
  6. Hi Guys, Long story short, - which one to buy for my NEQ6 mount? Now the long story: I am quite a beginner in this field and I saw quite a few similar posts... the main question is which one to take? 130PDS or 150PDS for AP. As I found out, 90% comments suggest going for 130PDS, as the main disadvantages of 150PDS are: it is a larger sail to catch the wind and it has a smaller field of view... But, I have managed to get a second-hand NEQ6, (not EQ5 or even EQ3 like most of the posts are about), and planning to plant a pillar for it in my garden, and usually, it's not windy in my place. As per field of view, My garden faces South, from South London, so of course, I will re-start with Orion and Andromeda in Autumn. And it looks like only Andromeda will not fit in on my Canon 1300D sensor in full and I am sure the rest objects are smaller than M31 So I am willing to go for 150PDS, However, most of the posts are advising for 130PDS... and it's confusing me at the moment... P.S. I do have 10" DOB for around 18 months, Light pollution hasn't allowed me to see Andromeda through it properly, so I have attached my Canon to it and WOW! This is how this 10" toy hooked me up on AP... and after 10", - I afraid 130PDS will be a bit too small in aperture for my back garden.
  7. My first attempt at M51 and my first attempt since I analysed what I got wrong on my first attempt at anything with my current scope and camera combination (a quick test run on the Pleiades in hazy conditions let me play with the setup but not the processing). It's only twelve minutes of data and a small scope but I'm not too disappointed with this result at this stage of my experience. M51 8 x 90 seconds, iso 800, 6" F5 newtonian. Canon 500D. Very quickly processed in deepsky stacker. Quickly processed partly because it was very late and partly because I really don't yet understand the wavelet image enhancement options in registax. Deepsky stacker does a good job of removing vignetting & dust bunnies, removing hot pixels and stacking. Registax is convenient for turning the tiff back to a jpeg but other than that I can't drive registax. The full details; All images taken through a skywatcher pds 150 newtonian (150mm F5) with an unmodified canon 500d. 16 x 90s exposures at iso800 of which the best 8 were stacked. Total exposure time 12 minutes. 18 dark frames 17 flat frames (probably badly done when I looked at the histograms later) Imaging runs at iso400 (10 x 90s) and iso 1600 (16 x 45s) were also taken but I haven't processed those.
  8. Hi to everyone! I have been asking questions, reading posts and generally pontificating for a while now but thanks to the advice of RikM and Starfox (and everybody else), I have eventually setteled on a Skywatcher 150PDS on an HEQ5 Syntrek mount. I was going for the EQ5 Pro synscan (with the goto function) but after reading all the posts and listening to advice I have decided to drop the goto in favour of a better mount. I reckon the entire setup should cost me about £980 just short of my £1000 hard limit including a Collimating EP, x2 Barlow and a 7.5mm EP. Any advice or comments would be appreciated (I assume I need to think about power adapters?). Many Thanks!
