  1. The TSA120/AZEQ6 arrived a while back and I was lucky enough to try it out tonight. This is just a brief report with more to come as I gain experience with this telescope. I'll get to the point here... even with Jupiter low and the seeing avg the TSA120 gave me the best view of Jupiter through a refractor so far... I can only imagine them when the planet is higher. The colors were very deep and with much detail showing in the belts and really fine shade lines through the caps were coming through. The eyepieces used were the Zeiss 25.1-6.7/VIP barlow, 3-6 Nagler zoom and a 4mm UO ortho. Th

  2. I've noticed that views through my dob haven't been quite as sharp in recent sessions. A quick check showed that my secondary needed collimating. As I've never done this before I was a bit nervous but a quiet Sunday afternoon gave me time to do it. I found it quite straightforward to do in the end. A star test was all that I needed to confirm that I had every aligned correctly but the forecast looked bleak. I still put the scope out to cool just in case! Come 9:30pm, I could see Venus shining through in a clear patch of sky so out I went. I spent a long time observing Venus, trying to pic

  4. Another Jupiter session, but the conditions were easily the best of the year so far! Obviously this is tempered by the fact Jupiter is slow and I have to play dodge the conifers ? A really frustrating week or so trying to get the best out this data, has resulted in this image. Not my best by any stretch. The usual set up, C9.25, Asi290mm,RGB filters. 90 secs per channel captured, stacked 10% Some nice detail, but I still think I am lacking in resolution with the Asi290mm at the native focal length. Stacked in A/S2, sharpened in CS2. Really struggled with Winjupos around the li

  5. After waking up around 4 this morning,i looked out the window "as you do" and seen it was clear with Mars and Saturn looking nice in the sky,so just to check it i could see Mars over the roof i opened the obsy and to my surprise i could just see it between the nieghbouring two houses, i turned the scope on,when i say could see it,only about 30% of the scopes full aperture could see Mars,but got a shot anyway, just for the record really. c9.25 and zwo 120mc.

  6. Another daylight session on Venus, but the conditions were clearly better than recently. Captured in daylight, at an altitude around 30 degrees. The usual set up, C9.25, Asi290mm, X1.8 Barlow & Baader UV filter. 15,000 frames captured, stacked 10% Some nice detail visible again. Stacked in A/S2, sharpened in CS2.

  7. Here we have Sh2-86, 88 and 90. In the upper right we see a few bright stars from the open cluster Stock One creeping in. The dark nebula (upper right) and rather attractive sea-horse-like emission nebula (lower left) have defeated me regarding identification. To get your bearings, M27 is not far off shot to the lower left and the Coathanger Cluster (Brocchi's) lies somewhat below this field. The lower panel comes from last year, HaLRGB, and the upper from two nights ago (HaRGB), both taken with guest Paul Kummer. Hardware: the house Tak FSQ106N dual rig with Atik 11000 mono CCD came

  8. With the very disappointing result with Saturday Obs session with the OOuk14. This washed and soft out views that were achieved due to the poor " seeing conditions " and certainty not the equipment set up. Then another crack at Jupiter was on the cards. This was a totally different evening and a totally different set up. The Sky's were cloudless and darkness was ever approaching. Jupiter showing brightly in the south. The atmosphere just felt different. Even though the air temperature certainty was not cold. There was a slight chill in the air and the atmosphere just felt that bit

  9. But not in one field I collected subframes for these two at the end of April and beginning of May this year, but just over last few days found the time to make some final processing. Conditions these days were not ideal - seeing was ok, but transparency was moderate under my suburban sky. So I had some hard time with colour balance and processing, but eventually I think I managed to set them close to proper values Setup was: Meade ACF 10" with AP CCDT67 telecompressor, QHY163M camera and EQ6 mount. Guided with SW 80/400 + ASI290MM. M106 details: LRGB 45:15:10:12 x 2 minutes. NGC4565

  10. I had to remove the dewshield from the scope as it was catching the balcony rail as I captured these images. I'm not sure if the blue fringing is because I forgot to check the ADC, or the fact that it was so light when i started imaging. 8" SCT 2x barlow ADC ASI224 Angie

  11. @John has sparked my interest in two double stars, Mu Librae and Delta Cygni; in particular whether they can be split with 70mm aperture. This session was under marginal conditions - according to Clear Outside, I should have been in bed - but I was at one of my better locations and Bjorn was along, so it was worth a shot. Mu Librae Currently above Jupiter, this one was located easily enough, but it wasn't going to come along quietly. That part of the sky was not the best quality just then, but we gave it all we had anyway. Still, all the way down to 200x, it wasn't apparent to me tha

  12. Hi, I am publishing this sketch from my observation last night at my very best observing site. I had an Ophiuchus theme to look at all it's interesting clusters. There is a mistake in the title, I have M10 but it's M12, both are 3 degrees apart in the middle of the constellation. The conditions were poor, transparency maybe 2/5 and seeing 3/5, the object at +-35 degrees from the ground approximately. Has usually, I used my 200x1000 Newtonian along with a 9mm Xcel-lx eyepiece, 60degrees apparent FOV, 111x. Even with poor condition the object had a clear and steady globular shape but.. all

  14. Got up at 3.00 with the Tak and Ioptron already set up. I had observed the two planets yesterday and seeing was good but right from the start it was clear that this morning the seeing was excellent. Saturn was sharp and steady as a rock. The Cassini division was visible all round and subtle bands on the planet showed up well. Given it's altitude the view was exceptional: the 3D quality of a sphere within the rings was thrilling. Titan was also clearly visible north of the planet despite the lightening skies. I had to wait a few minutes while the planet was eclipsed by my local telegraph p

  15. Hi, A large box arrived. There are clear skies. How can this be? ??? Well, I'll tell you how, its that sellout gold trim around the edge of the lens and the sellout slo-mo focuser handle! My new OpticStar f/8.8 90mm frac, from @Mr niall! Apparently this telescope produces clear skies, as the seller has testified--this could well be an alternative to @FLO's Zarkov cloud gun! It has a very nice focuser design, with just one screw not the standard 2. This works with a thin metal strip which tightens when the screw is screwed in. Hopefu

  18. After watching 'The Sky at Night', appropriately on the Juno mission around Jupiter, the plan was to image Jupiter until around midnight when clouds where expected to crawl in. So setting up my C8 on my goto mount at 10:30pm in the back garden I noticed cloud already building up, so it became a race to get the scope set up, the laptop & ZWO attached to to get some images before total cloud out happened. I managed to get 3 files of over a 1000 images each (the first one was 3000, but I limited the next two files to 1000 each). The results of the first file is as below, which came out with s

  24. Hi, In my recent thread on waterjet cutting I mentioned that I needed a quick and dirty AltAz mount to help with setting up my FSQ106ED. Eh voila - he is here! No doubt I will be getting requests from all the major mount manufacturers for details of this revolutionary product - however, the secrets are revealed here for the first time!! As you can see, a minor height adjustment was required before full operation was possible but after that - yesssss! A view of Dartmoor through a ZWO ASI1600MM. Both cameras working, filter wheel good. Altogether a much happier chappy now. Hugh

  25. Managed to get a little bit done on Saturday night before clouds rolled in and ruined everything. Looks like I’ve got the alignment issues sorted though so that’s a plus, and my new mini bahtinov worked well too. Image is fairly unspectacular, needed more subs and definitely would have benefitted from flats. But... onwards and upwards! opinions / criticisms welcome - I’ve included the tiff in case anyone wants to prove / disprove whether I’ve done ok with average data or whether I’ve messed up royally!

  26. Here are my latest two which I'm planning on being my final scope purchases for a while (fatal last words I know). ? First up my new to me Altair Starwave Classic f11 which comes to me via @DRT and @Jonk then secondly a new to me mint condition Celestron Omni XLT 102ED f9 which comes to me via @Lockie and @Saganite. I've only done a bit of terrestrial observing and some WL Solar this evening and the views have blown me away, but that's for another thread.

  27. When I started writing this first light report I said to myself that I won't make it seem that this Tak is so much better than other telescopes. I purposely understated how well this scope works Chris- it is extremely good. Even under avg conditions, with Jupiter low the 120mm + the HR2.4 at 375x showed the GRS well, riffles in the bands and polar shading. Many other things were tried and once again this telescope is top notch. I don't want to make it seem like other scopes are not good though, Gerry

  28. Well it's been a while since I last managed to get out with the scope due to work, weather and holidays. Tonight I saw Venus beckoning me when I really should have been heading off to bed ready for an early start in the morning, but I just couldn't resist. Scope out and got lined up on Venus, the planet phase really seems to have changed since last time I managed to look at it which was back towards the start of May. Managed to track Venus for about 10/15 minutes but the clouds moved in and started to obscure view. To the south I could now see Jupiter calling so I spun the scope ro

  29. ... or gray As an imager who obsesses over things like bit depth, detail, resolution, colour balance etc etc I was wondering how many shades of grey I could distinguish. I know my monitor can display 2^8 =256 levels but that doesn't mean I can actually see them all as different (my age + early stage cataracts probably don't help...). Apparently the normal human eye can only discern between 30 and 50 shades of grey. Anyway, I had a go at an online (but non-scientific test) and it said I could distinguish 37. I found it really difficult to decide whether two close shades were actually differe

  31. As it was a nice sunny day I tried a little WL solar viewing, but as it was just like looking like a ginormous white snooker ball, I decided to switch to Venus (with the help of my trusty goto mount). After looking at it visually with my C8 SCT, I decided to have a go at imaging it. The below image is the best result I got out of 3,000 images with my ZWO ASI120 mc, with a light blue filter fitted (not that you'd notice with the colour of Venus). Seeing was pants, but the image came out much better than expected. Used Registax, then PS to crop & alter curves a little. Flipped image for corr

  32. Thanks Shaun, this scope has the fastest, best "snap" focus" of all my scopes, just ahead of my 15" dob. My first view through it was across the bay at about 800 yds, at the trees. The 3-6 Nagler popped the trees into razor sharp view at 150x... unheard of in the other fracs- from this I knew it was going to be good.

  34. Gerry you have report on what your findings are..... if people think it is boasting then quite frankly that’s their problem. I for one prefer honesty every time, and I do not write reports based on what folk want to hear ? The Taks are quite simply very good scopes and you my friend just happen to have a very nice example.

  35. I'll post these in a separate thread as they may be of wider interest. I've completed all the parts for the Crayford focuser for the 66ED scope I am making. There is still some fine tuning to do to make it run smoother and correctly adjust the speed reducer and some cosmetic finishing. Also I need to make a deeper collar with a compression ring and then there's anodising... I thought I'd copy Williams Optics idea of having a hygrometer on the 'unreduced' knob, but I went for a digital one with a thermometer as well ?

  38. Yes, seeing on Jupiter was excellent last night. Only downside was I only had about 10mjns observing before total cloud cover ensued once more. I did manage to get a pretty good image of Jupiter showing some nice detail though with my first of three small imaging files I managed before Jupiter was hidden from view.

  40. Thanks for that comment Dave, as you say counter intuitive, but very true. Spent yesterday fettling and playing, and yes, reduced spring force made a great difference. Previously I'd let Sitech handle the backlash, but I've now let PHD handle it, here's last night's first run (edit, actually it's from the previous night): As you can see horrible periodoc error, so ran Sitech's Auto PEC routine for 9 worm revolutions: I was amazed at how the RA error just kept getting smaller on every revolution, really easy to apply. Let's hope that everything is now stable

  42. Mark, These are 72mm F6 TS Apos. Very easy for aircraft cabin travel. Possibly the 90 you refer to might be as well, obviously slightly heavier and longer so might depend on your bag and or airline. Performance wise very pleased, the rack and pinion focuser is really well engineered so much nicer than the SW Crayfords!

I have a nice 6" rotary table (a bit big for my mill, but it does fit) that I got to make a 10" gear for my Jovilabe (must make that gear some time!) it will be ideal for making large precision worms. I've made small worm and wheel pairs before by free hobbing, for a dividing head/rotary table and a tiny dividing head. I made two worm for each on, one in silver steel, which I gashed to make a cutter then hardened and tempered. I'm far from convinced of the accuracy of the resulting gears, which is why I ended up buying a 'p

  47. Nice write up Neil. I managed a very brief look at Jupiter, which showed great detail. Alas, clouds rolled in too quickly to end my very brief session. I did manage this image of Jupiter though that came out pretty well, taken approx 10:55pm, which shows how good the seeing was!

  48. Use DeepSkyStacker http://deepskystacker.free.fr/english/index.html You can use it for stacking and for aligning the different channels. To align channels is not immediately obvious but is briefly described in the FAQs. Choose the sub you want to align everything to. Lets say it is one of your green subs. When you stack your green subs, right click it and select "Use as Reference Frame". The reference frame is identified by "(*)" It will also be ticked so it is included in the green stack. When you stack your Red (or Blue) channel, add the chosen green sub, right click it and s

  50. Do you use a cutting fluid when turning? I started using odour free lamp oil [UK paraffin oil] after seeing a tip online. It has completely transformed the finish I get on aluminium. I just keep brushing it on while I'm turning. Cheap as chips from the supermarket. This is a 7" [180mm] cylinder for my big DIY GEM on a 2" mandrel in my old S&B 'Sable.' Turned with a boring bar to reach along the side. There was no room for the usual tool arrangement.
