    The AZ-EQ6 arrived from FLO on Tues. Last night was its first outing, meeting up in a field often used by the Chester AS. The day had been sunny with deep blue skies, but en route it clouded over, of course! Set the mount up in AZ mode on the Berlebach Planet tripod and a C9.25 and waited for dark whist relaxing with a can of beer (astronomy has to be relaxing ). The flight of several skeins of geese moving from one field to, presumably, their overnight roosting spot which they do this every evening at dusk at the moment, signaled it was time to do the 2-star alignment, which was really easy (experience with the AZ-GTi helped). Had to make do with gaps in the cloud, but this is where a GOTO really helps: “there’s a gap in Andromeda, let’s head there!. Jupiter and Saturn were remarkably good and reasonably stable – probably the best views this season. Added two further planets: Neptune and Uranus. As the conditions weren’t brilliant, I’d already decided I wanted to observe some globulars, so I caught M2, M56, M71, M72, M15. I was really impressed with M2 – it’s been quite a few years since I seen it. Also threw in a few planetary nebulae: NGC 7009, M27, M57. Oh, and M11 the wild duck. Complete cloud at 1 AM brought a stop to proceedings, so it was a matter of loading up the car and driving the 15 minutes home. An evening that had started poorly, yielded quite a bag of objects and I felt worth the effort.

    Out observing the Moon from 1.40 am this morning prior to the Hyades occultations later - the first event being the occultation of a 3.8 mag star at 3.43 am. The lunation was truly wonderful. The pictures below show the terminator from Copernicus to Frau Mauro (and the Apollo 14 landing site), Mons Recti Teneriffe and Pico (the latters peaks just visible) and sunset over Clavius and the area around it. The detail was stunning in the 120ED visually. The pictures are all crops from the same single frame taken at 4.14 am, 1/250 sec at 500 asa. In addition to the disappearance of the 3.8 mag star at 3.43 am, I saw a second occultation of a 4.8 mag star at 4.26 am and finally the best event was the reappearance of the same 3.8 mag star from behind the dark side of the Moon at 4.53 am. When it popped out it was like a bright lamp suddenly being switched on. It was beautiful with the bright star (yellowish to my eyes) adjacent to the dark limb and then the illuminated lunar service. Great views of the Moon and occultation events, well worth only getting 1 1/2 hours sleep!

    Rob's comment above regarding a observing hood is good advice. Many members on SGL bought this quality observing hood from this company in Russia. I use it whilst solar observing, binocular viewing and DSO hunting especially those objects that are faint. https://r-sky.org/en/products/observing-hood

    Working my way through it and taking it seriously, even though ATM I pretty well know everything in Week 1, as, I think, pretty much everyone on here will. Went through the Week 1 quiz with full marks (Would have been ashamed if I hadn't), now onto Week 2, Visual Observing and Telescopes.

    Here you go, mentioned in this report from Devon. Mag 20.5 skies with the C8 Edge so should be a doddle with your scope.

    8.55pm, just a little thin cloud, Jupiter on show - set up the ED80/GoTo, aligned on Jupiter, spotted the Galilean moons in a nice line, two each side. I checked the GoTo with Albireo - a close pair at x24, but the blue and yellow components stood out beautifully. Next, Sigma 2523 (Vul) - a matched binary, 6.3" separation. Just split at x80 - a fine spectacle with other stars nearby. AV really paid off, easily showing fainter neighbours which otherwise were elusive. (See image.) On to the famous Coathanger Asterism, part of Brocchi's Cluster (not actually an open cluster) again in The Fox - the ten bright stars showed the (inverted) shape very well. Right at its western end lies the dense, elongated open cluster NGC 6802. I had just the briefest glimpse of this before heavy cloud stopped play after one hour of action. Session no. 56 this year - short, yes, but no less enjoyable for that! Doug.

    Me three- though for only 3 hrs Nice to think of us all out there separately looking up- connected in some way. Seeing is getting better and better- last night was the best session yet- found loads of new things including first look at Uranus! Gave up a bit frustrated not finding Hercules cluster but I couldn’t really make out the constellation so was just swinging the scope around in vain not really knowing what I was looking for. Sometimes it’s tempting after a few nights of clearish skies to think I’ll not bother- just more of the same, but persistence definitely paid off last night for me

    The Moon this morning at 03:15 to 04:00 BST 20.7 days waning. Seeing was 4-5 on the Damian Peach scale and a high mist at the start. As I have had to send my LX850 handset off for repairs so I used my 9.25 SCT on the Evolution mount. Cameras were the Canon 650D as a 2 pane mosaic for the whole shot and the Altair GP290M for the detailed shots. I was worried if I tried 5000 frames there would be too much image rotation as the Evolution is an AZ mount. Each image was 2000 frames and between 25 -70% of the best frames stacked in Autostakert, wavelets in Registax and finsihed with PhotoShop. The GP290 is a very very good camera https://www.flickr.com/photos/165584972@N02/albums/72157710492838572

    Hey guys, three days ago I started gathering some data for the Dark shark. Due to the FOV of my setup I can't fit the whole nebula in one pic so I'll have to do a 2 panel mosaic. As it's my most favorite nebula and so far I only captured it in a widefield using Samyang 135mm with Canon 6D so it was super tiny. Now I finally tunned out my setup to do it properly. As I already mentioned I think it's just so amazing and the resemblance to a shark is really uncanny so I'm planning on spending some real time on this one. I've planned out 15-20 hours of luminance data for each panel with 5 hours for each colour filter for each panel. My current record is 22 hours of integration time and I aim to surpass it more than twice . It's gonna be real pain but I really hope it'll be worth it. This is the result so far after three days. 103x5min (8,6 hous) of L data for the left part of the mosaic. I was surprised how visible it is after this short amount of time, I processed it in Pixi but only did DBE, Stretch, Resampled it down by 50% and fiddled with curves. In the full resolution the noise is still problem but it should slowly disappear after I add more data. Telescope: Explore Scientific 102/714 APO Triplet with 0.8x reducer Mount: iOptron CEM60 Camera: ASI1600MM Pro - Gain 0, Offset 50, Cooled to -20 Update 28.8.2019: Last night I finished shooting of the head part and mannaged to squeeze a few shots of the tail part as well so this is first preview of how it's gonna look like You can see the difference between the head with 12 hours of data and the tail with just one and a half, I need some clear moonles nights. 7.9.2019 Update: I've managed to finish Luminance acquisition, so far 31 hours but I had to throw 7 hours out due to a lower quality. Now I'll have a couple of weeks of NB imaging as the moon starts to grow, then I'll hopefully do the RGB. Cheers Jan

    This was my first attempt at a sketch. Was battling clouds the whole time, so that added to the challenge. Let me know what you think.

    I have been modifying my Heritage over some time and I thought I would show what I have done. Starting with the Dob base. I have added an Alt scale and Az scale. Improved the secure knob on the base. Added a compass Added a spirit level. On the main OTA Added new adjustment screws to the secondary (my Bob's Knobs) Added a finder bracket for my 9x50 finderscope Flocked the area behind secondary Painted the edge of the secondary Flocked the inside of the scope Added a neoprene shroud Added yellow stickers to make sure the mirror cell and tube go back into the same screw position Added plumbers tape to the focuser Finally added an additional dovetail to use on a flat alt/az tripod Hopefully these photos will show what I have done. Looking at the photos perhaps I need to clear the main mirror and secondary

    That's such a hard decision to make right now!!! I really don't know.. It's still around 422$ and very expensive for a guide camera. Maybe I could get the 120mm and then invest in the 071 cooled, but if not I'll for sure get the 294mc.

    In light-polluted skies you should get a much better dark-sky experience if you put the eye-patch on to your observing eye

    Hi Alan, As Laurin suggested, best check which camera is Asi camera 1 and Asi camera 2. I have been down that frustrating road and an easy way to see which one you are connected to is to check the pixel size for each camera (online specs etc), then click on the brain on PHD2 and select the Camera tab. At the bottom left of the screen you will see the pixel size being used for calibration. If its your imaging camera pixel size, then you need to go back to the connection settings in PHD, click the spanner icon and choose the alternate camera which will be your guiding camera and remember which is which. Hope this helps, John

    Hi, here is a simulation of what you can expect to see of Saturn with your scope and a 6mm ep (as Peter says 150x magnification, with your scope having a maximum practical mag of 140x).

    Excellent session Jeremy. I do like the AZEQ6 mounts, really stable and easy to use. A bit heavy but manageable. The Berlebach tripod will help with stability too.

    2" will certainly give you a wider FOV but you will struggle with the DL due to its longer focal length. The DC is just on the limit really, ideally you need about 650mm focal length or less to be comfortable. John's lovely Vixen is f6.5 and that does it nicely, my Genesis is f5 so is even wider. These charts show the DL, DC and Genesis with first a 24mm Panoptic (1.25") second a 30mm 82 degree ES (2"), the third one is a 41mm Panoptic (2") and finally a 56mm Plossl (2"). In each one, the DL is the inner circle, DC mid and Genesis outer circle. So you can see the DL is always going to struggle, with the Plossl giving the same field of view as the 41mm but with a larger exit pupil (6.2mm) which may help when filtering with an OIII under dark skies. It is certainly the cheapest way to start experimenting! So, you will get wider with 2", but it may be simpler to get a different scope with a shorter focal length although you would still need the 2" eyepiece.

    LCO take twilight flats at the end of each night but other observatories use dome flats - some do have huge light panels for this purpose Helen Ps what are you doing with LCO? Is it FT? I work with the FT team

    Nice report! the ST80 is such a handy scope to have. When you upgrade to a larger scope you can still use it as a super finder or guide scope, as well as a grab n go!

    It's very easy to flip the glass in a mounted filter, just cut a plastic sheet to fit the locking ring to unscrew it and flip it

    Thought I was in for a good night but high level wispy cloud interrupted viewing constantly. Started off with Jupiter which was ok at best, Saturn was crisp and detailed before cloud came over. Managed a glimpse of the eastern side of the Veil with my OIII filter & 24mm pan, thinking I will have to invest in a lower power eyepiece (35mm pan?) to see the whole nebula instead of bite sized chunks. M13 was an absolute delight with my 3-6 zoom, like opening a box of jewels. Finished off with Zeta Herculis, not convinced I managed to split it at x225 it seems like a wobbling miss shaped airy disc on one side? apologies for poor description!

    I can understand issues with storage, but problems with setup? You place the base on the ground, and then put you OTA on that base and you are ready to go ... Not sure that any other scope will have advantage in this regard - it is as good as it gets - place the mount on the ground, put the OTA on the mount. Only thing that is going to beat that is grab&go setup - you place the thing on the ground and you are ready to go. Mind you, such grab&go will have much lower light gathering and you won't be able to see as much of deep sky as with 8" aperture. Planets and the moon will be doable (although again, aperture is important there as well).

    I have the Meade LX850 running again and tried an Altair Astro GP 290M cam, a small mono ccd fast frame camera. Though a smaller chip than my AA178C I normally use the performance is excellent. 20th August morning at 03:00 BST was also very very stable for seeing. On the Damian Peach scale, almost a 5, something we do not often get in the UK. The GP290 was running in MONO12 bit mode, and I used either 2000 or 5000 frames. Easy as the camera was working at 45 fps, fast. For the detailed shot I added a Powermate 2x to the chain. The whole shot was a a mosaic of 4 images shot on my Canon 650D. Processed in Auto Stakkert and the adjusted in Registax using a 1.5x drizzle and a final tweak in Photoshop.

    Hi, I'm relatively new to the hobby. I was doing just visual observation but have decided this year to give AP a shot. Just wanted to let you know that I received the Ed72 today, looks like a great little scope. I have mine mounted on the Eq5 seems to be fine, will keep you posted once I can get out and actually use it

    Some really neat targets in Aquila. Not the best of skies , had to use a bit of magnification to tease out some more contrast. Very nice.y place for a comfy seat snug up against the fence. Our hedgehog came for his feed, topped it up (again). A real stunner was Σ 2677, just by averted vision , the very faint secondary popped out . Seeing was superb with good transparency. I use π Aquilae as a tester . Getting h881 was a real triple treat , under ,clear skies ! Nick.

    I can add this here aswell now, Tak on my Vixen GP mount, dual MT1 motors and DD3 controller. The pillar is also Vixen, puts the scope at a nice height but can still be carried around easily.
