  1. My first crack at the planets this year reasonably pleased at the outcome, unfortunately only got a couple of runs on Jupiter before daylight! Images taken with a C9 & skyris 236m camera! Thanks for looking!

  3. I had a go at Jupiter and Saturn using my 8" Dob but this time I did a movie with my DSLR and stacked it in Siril. I tried an eyepiece projection with my 8mm. I need to invest on a proper camera mount setup for my DSLR (I have the M42 ring for prime focus but I was hand holding it on the EP). Very pleased to see the red spot in Jupiter but my Saturn was not so sharp.

  4. Just had a 4mm arrive so we are almost there. Just the elusive 6mm and 5mm to go. Compared to the others the 4mm doesn't have a sharp field stop and doesn't appear to be adjustable either. As long as the image quality is there I can put up with that. Exciting times! Magnifications in my 250mm: 25mm - x48 18mm - x67 12.5mm - x96 9mm - x133 7mm - x171 6mm - x200 5mm - x240 4mm - x300 The missing ones are needed!

  6. 9.55pm Tuesday, Moon (2 days to full) low, east of south, sky clear, Sun only just set. I put the fine little ED80 Triplet to use for a change, partly to avoid being overwhelmed by the glare. To the south - Schickard, near terminator - going from x80 to x120, six larger pits were seen (one on the rim), also a few smaller ones. Seeing was variable, occasionally quite unstable. Going north, Babbage was very close to the terminator, well lit, apart from the large crater in its floor. But the best apparition was from Pythagoras, just above Babbage, and right on the terminator. It was

  7. Still a 20 or more days before enjoying the first summer nebula pass over the roof. As many other fellow, this is the time to rearrange, clean, fix and prepare the setup for the nebula season. In the meanwhile, some shot from lost corner in the hard drive, left there, are a good way to spend some time. Awaiting the clear sky.

  8. Started about 11.15pm I wanted try some clusters in Ophiuchus M10, M12 and M14 they did not disappoint but the highlight was NGC 6572 (Blue Racquetball) When I first looked I thought it wasnt there but on closer inspection I saw a star not in focus more magnification and there it was a beautiful blue diffuse ball a great site. Sagitta Hn 84 + Σ2569 (SAO 1051 04) This is two pairs of stars Hn 84 has 6.6 and 9.5 mag stars with 28.2" separation and Σ2569 has 8.4 and 9.1 mag stars with a separation of 2.1" colours I could see yellow/orange and pale blue just grey dots for second pai

  10. Eplison Lyrae is the famous "double, double" star in Lyra of course and very nicely presented it is at this time Tonight though, when observing the Moon, low down amongst the stars of Scorpius, I also took some time to have a look at the nearby background stars and came upon Nu Scorpii also known as Jabbah. With my 100mm refractor at 225x this star proves to be rather special and actually a multiple system. At it's heart are a couple of close pairs of stars known as Mitchel 2 and Burnham 120. The dimmer pair (Mitchel 2) are 2.3 arc seconds apart and the brighter Burnham 120 pai

  11. Another shot of my easily accessible local subject, Burrow Mump. This time with the Milky Way arching above it. Taken over the recent new moon with my modified Canon 6D and the Samyang 14mm f/2.8 stopped down to f/3.5. This is a 27 shot panorama... 9 profile panes, 3x 20 second shots per pane stacked in Sequator. The resulting images were stitched in Autostitch and the image then tweaked in Rawtherapee and GIMP. The foreground and the ruin were lit with a couple of Ulocool LED lamps at 2500k and 5% intensity (these were a great Amazon buy!). Unfortunately I couldn't get the sheep

  14. Mystery objects! I'm adding them to my Bresser 10" dob to give me push to... I tried star hopping with it but the views from my back garden are too restrictive really and I find myself getting out the little 130PS and its AZ-GTI for goto so I get to see things instead of just looking for things.... It's an I2C 14 bit rotary encoder. I ordered two - one for each axis. Been waiting weeks - on back order for ages....

  15. Well, I’m pleased to be able to report success last night! I was using the scope Japanese style, straight through until the diagonal arrives, so it was fairly uncomfortable! I had a quick look at the moon which was a bit wobbly but fun to see. Floaters were an issue with the 15mm (x15, 0.39mm exit pupil) but still surprisingly sharp. Schröter’s Valley was on display and well illuminated. It’s a long way from my Telementor (not surprisingly) but not bad. A star test on Vega was OKish. Possibly a slight flaring to one side but not disastrous. Will check this more when I have the diagon

  17. Hi, I tried out my Atik 0.5 Focal Reducer on my Vixen VC200L, the other night which I bought ages ago, but have never used, until now. I got the reducer to enable me to have a go at some lucky DSO imaging with my ZWO ASI178MC. Anyway I went and tested it out on the Moon. I was very impressed by the extremely sharp images of the Moon on my laptop screen and thought "hey, my images are going to be amazing". However, after running my images through Autostakkert and seeing the result, I was disappointed. My images taken at 3096 x 2080 Resolution looked O.K, but the sampling? on my 192

  18. Just to bring this back to the ‘small is beautiful’ theme, I was using my Prinz Optics 550 last night for the first time at night. This is my £5 eBay scope, and last night it gave me some nice views of the Moon and a ‘just about’ split of the Double Double. Good fun.

  20. Well, I finally have a set up that i'm happy with (For now ). After cracking a 3d printed ring that held my Samyang lens in place due to over tightening, I realised I couldn't trust a lot of very expensive gear to a plastic holder. So after scouring this thread for ideas I came across a very nice system from @Adreneline that looked like it would do the job & I would like to thank Adrian (and others on the forum) who helped answer a fair few questions I had for him. I also decided to mount side by side as 'piled' one on top of the other the system had balancing issues. I still need to so

  21. The brightness of the GRS varies quite a bit from year to year. Likewise of the equatorial belts. I have seen years where the SEB was almost absent, as shown in an early shot of Jupiter with a Philips TOUCAM 2010 A year later it had bounced back 2011

  22. So.. Building work on the walls done, and a call from Steve at Pulsar to say he had a cancelation resulted in my dome being delivered / installed today! All up and running. Just a minor hitch in the moulding that I noticed after Steve and Gary had left on one of the dome's quadrants has resulted in a bit of a "clunk" when that joint passes a runner wheel. I Should be able to make it smoother with some Epoxy Putty or the like, so not a big deal I don't think. Waiting for my new mount which is on back order anyway. next job... finish the new patio, (needs a bit

  23. Hi all Well, I woke up at about 2am this morning and couldn't get back to sleep. By about 3am I'd given up trying and decided to head out into the garden to see if it was worth getting the 'scope out. I could see what appeared to be two bright 'stars' and hoped they'd be Saturn and Jupiter. I smuggled the 'scope out of my bedroom, almost without waking my wife and was proved right. I easily managed to make out Jupiter and three moons. I could just about make out a band on Jupiter, but otherwise it was just a very bright disc. I managed to make out the rings of Saturn which actually m

  26. I have no idea why they state four hours to clear the settings in flash memory !! At least this way will hopefully get you connected.... often after making multiple changes you can be chasing your tail trying to resolve an issue - often the best way is to reset and start over, and then make one change at a time, testing to see if they work. Hopefully the update you'll post later today will be a positive one

  27. I know the great red spot on Jupiter was recently given a clean bill of health: https://skyandtelescope.org/astronomy-news/jupiters-great-red-spot-gets-smaller-but-stronger/ But... this morning I was observing Jupiter at about 4:30am in morning twilight and was struck how pale GRS looked. It seems smaller than last year and certainly much fainter than the colour of the north equatorial band. This recent image by @si@nite seems to support this. I wonder what is going on.

  28. It's my belief that manufacturers tighten the mirror clips to prevent the mirror from flopping about during transit from China to wherever. One of the first things to check on the receipt of a new Newtonian.

  29. I have been running INDI/Kstars on a Rock64 (Rockchip RK3328) for several years, and also have a RockPro64 (Rockchip RK3399). Because the RockPro64 is larger, I haven't mounted it on my telescope yet. (I bought it because it uses 12V instead of 5V, so one less cable.) I use Armbian as OS, and have the stable pre-compiled version of INDI/Kstars installed, which runs without any issues. I think I must have been one of the earliest users of 64 bit systems, because I had to ask the developer of linux phd2 to add 64 bit to the repository. Anyhow, early problems were mostly related to instabilities

  32. Funding can indeed be a problem, but sometimes you don't need that much. If you can enlist a few amateur astronomers/astronomical associations and their telescopes, plus transportation, you can do a lot. About a decade ago, back when I was working in Mexico DF, we did a "Night of the stars" in the Zocalo (the main square), with people from the Astronomical Institute in UNAM and some local associations. It was just a decent number of small/medium-sized telescopes, laser pointers to show the constellations, and "ask and astronomer" stalls (well, and a few other more complex setups, but those wer

  34. There is actually a dark-sky park in Wisconsin, Bortle 1-2, up in Door County. I hauled my wife up there for a few days, figuring we could have fun during the days, I'd image and she'd play Horizon Zero Dawn at night, and I would sleep when we got home. If you look carefully you can see that the first image's field of view is almost contained in the second's; they were both shot with Pentax APS-C DSLRs, the Rho/Antares with a 50mm f/4 macro and the Milky Way with a 14mm Rokinon. The first one was mounted on my CEM70 with autoguiding and used a variety of exposures for about two hours of i

  36. I was out with my heritage 150 dob from 2am until about 3:30 am (after putting my new refractor through its paces earlier while the Moon was up ) I had to take the dob out , it was my first proper scope and yesterday was its first birthday I got a quick look at Saturn (which, with the poor seeing appeared to fizz like an effervescent tablet with any serious magnification) before it vanished behind the trees, Then switched to faint fuzzy searching, and having finally managed to see the Dumbell Nebula which is somewhat of a challenge in my light polluted back garden, , I spent the last 30 min

  37. My back garden southern observing "window" is also a narrow gap between houses. I managed to get my first glimpse three weeks ago but could split only the AB and CD pairs at 41", neither would give up any more (the CD/Mitchel2 pair should be within reach of my 6", in the right conditions). I read that the system most likely has seven components!

  42. I don't know the specifics of this scope, but some scopes actually require the secondary to be off center so it may not be a problem as such Worth a look at this guide - https://www.astro-baby.com/astrobaby/help/collimation-guide-newtonian-reflector/ If you are still sure that it needs to come further up maybe carefully remove the center bolt and add a washer or two to give you the required extra travel?

  46. Taken in daylight before the sun was set. Was pouring water all over the patio to cool it, after baking in the sun all day. Wanted to try my 245mm Newtonian. But not under these conditions. So the little scope gets some use. The EQ5 eats it up, i can actually focus and see it. Though still a tiny wobble. The virtues of long focus refractors comes out in leaps and bounds with this model. Small it might be, but its also sharp and contrasty. Not bad for £30 from astroboot. QHY462C UV IR CUT More black

  47. Some of my personal "tough tests" at this time of the year are Zeta Hercules, Pi Aquilae and Lambda Cygni. Eta Draconis is also a challenge for 100mm and below. The split there is 4 arc seconds but the brightness difference between the primary and the rather dim secondary star make the challenge.

  48. I totally agree @Stu1smartcookieI own a Skymax 127 and 72ed ds pro on az gti mount. As I live in a first floor flat portability is paramount to me, everything needs to be taken down in one trip as I image from a communal area so can't leave my equipment unattended at anytime. I can get my 72ed out on the mount and tripod in minutes and set up in around 10-15mins in az mode. I used to have a sw 150p eq3-2 when I thought aperture was king for me, as only used to view and image through a bedroom window pane and never once got the scope outside, so this was sold to find my 72ed. Now I can use my s
