  1. Nice lunar image James but I think you know what needs to be done 🙂

    Get that 174mm out and have a crack at it. Not sure what scope/s you have but I had a 6" SkyWatcher reflector at a focal length of 1000mm and did 2 videos, one for the top half and one for the bottom half of the moon stitched together and it came out very well in good seeing. It was at a larger resolution to what I usually do and it was one of the best lunar images I've done over the years.

    Excellent image.

    I see you are down under. What is Jupiter's elevation like down there?

    Thanks everyone.

    @maw lod qan Jupiter and Saturn are just over 79 degrees. Jupiter at it's highest just after 7pm and Saturn just after 9pm. In a couple of weeks time light from the setting sun will start to creep in for Jupiter when it's at its highest.


  3. Last of the Jupiter videos from yesterday evening, I think this was the best of the lot. Conditions average to good, Mandurah Western Australia.

  5. Nice one Stu. I would've expected Saturn's curve to be closer to Mars and Jupiter but you're right. I checked Stellarium, as accurate as that is years into the future and at mid Winter 2026 it's roughly 55 degrees at 8:20am here and for 2032 it's 35 degrees around midday near the sun 😮

  6. I don't know about anyone else when the planets were higher in the Northern hemisphere but I rarely see much detail on live view and only a couple of times visually. I guess filters would help with eyepieces. When I do see it on live view it's fleeting, very faint and always washed out by the brightness.

    This was from the ZWO ASI224MC about 6:37pm that same night. Ganymede down the bottom. The Neximage 5 couldn't pick up the moon, only some of the shadow but I would put that down to the seeing and slower frame rate of the Neximage 5.
    I much prefer the colour that the Neximage 5 gives compared to the 224mc, I can spend hours trying to get the colour better with the 224 and still not get it right. I gave up on this image in the end as I've spent way too much time of it.

    Love it! Well done! :) Jupiter up here in Blighty is pretty much pants at the moment with the low altitude of Jupiter, and the flipping jet stream blowing above us! Sheesh! ;) 

    Yes we're getting a bit of the jetstream too and need to dodge the clouds here. We seem to have sky mist which fuzzifies detail. I haven't had many good or better seeing nights where I am. The only thing going for me is the elevation.


  8. Crater Walther, approximately 132km × 140km in diameter and 4km in depth with complex crater rim. Seeing conditions average to good, Mandurah Western Australia. Captured on the 9th of August.

    I'm quite pleased with this result as I've beaten my PB to resolve down to about 2km wide craterlets which can be seen around the central region of the crater floor even when conditions were not the best on live view.

  10. Lunar early last night. Conditions started out as average to good but slipped away to poor just before clouds rolled in. Visual observations of the lunar surface were quite nice, heaps of craters to explore with good detail. This image is a 2 stacked image stitch. Location Mandurah Western Australia.

  11. The Gem Cluster NGC 3293 aka Spider Spit Cluster, Little Jewel Box from the 30th of January. I was so pleased to bring out so much on this open star cluster and surrounding area, perhaps I over did it? Not perfect star but very happy with the result.

    Very very good. I am curious - you say focal length is 1000, but how do you get there with a 2x barlow?

    Sorry for the confusion, the native focal length of the scope is 1000mm, with the 2x Barlow 2000mm. The resized image was at 200% using the Mitchell filter in RS6 😉

    This is the first 6" short tube I've had and often wondered how they get a long focal length from a short tube. There is a metal barrel at the end of the secondary mirror pointing towards the primary which houses a lens. I'm wondering if I took that lens out if it would make it a 500mm scope. The only other thing would be the focus plane and if I could reach focus if I took the lens out. If it could focus it would be a nasty f/3.3 scope and with heaps of CA I'm sure 😁 just not sure if it's a 2x magnifying lens.


  13. Jupiter and Io and Saturn from the 2nd of August before clouds rolled in. The second Jupiter image was resized in RegiStax. Conditions average, Mandurah Western Australia.

    Dave I tried M55 last night which only gets to 17 degrees at best and though it was not the best of nights I did get something to work with and get a result, the difference is, south I have nothing until Greece.

    Alan

    Nice Alan, as long as you get something for your efforts. I do like the star clusters especially the globs. Have only done a couple I think that turned out ok. I might post one just for giggles. I don't think my 10" primary mirror is a good one as my stars are always weird shapes.

    Tricky here, have to put a scope at the right spot in the garden and catch it between some trees.

    M31 ? no bother Dave :D

    Dave

    I thought you'd be in a prime location for M31 Dave. You're in the UK or around that neck of the woods?
    I'm being more selective now and only go for the higher targets.

    Very pretty Dave, what elevation is it at in your neck of the woods ?

    Dave

    Cheers Dave, about 81 degrees for some months :) It's a nice easy one, I like easy one's.

    Alot higher than in the UK I am sure, nice image David.

    Alan

    Thanks Alan, ain't all the good one this side of the rock?? 😀
    Honestly though there's some good targets in the northern hemisphere where you are that we can't get and are too low. I would really like to get a chance at imaging Andromeda M31. That's at about 16 degrees north and in light pollution from along the coastline here. I can't even see it.

    Nice image! ...and lens! :thumbsup:

    Cheers Philip :) The lens looked nice, felt nice, build quality was great and looked good on my Sony a5000 mirrorless but it wasn't a star performer so I sold it. I'm slowly collecting a few nice prime lenses from the old 35mm film cameras. I love the old glass, there's just something about them that are so appealing.

  16. The Lagoon nebula taken early May this year with a Tamron BBAR Multi C 300mm f/5.6 telephoto lens stopped down to f/8 and Sony a5000 on EQ6 Pro mount. This is a re-edit and heavily cropped just to show the nebula and surrounding area. Captured in less than ideal conditions from Mandurah Western Australia. The stacked image with this lens showed blue doughnut rings around medium to bright stars and was difficult to get rid of, I did leave some around the neb and lightened them a tad.

    I hope so - looking at my results I started when Jupiter was in Orion using webcams. Each year my gera and technique got better but Jupiter got lower and my image quality stayed more or less the same. Hoepfully over eth next six years both my skill and the seeing will improve together!

    I'm sure the planets could be moving northwards, they don't seem to be as high as last year.


  18. Well done Neil. I had a look at your first video and it's a good result for that type of seeing and at such a low altitude.

    For me in the south west of Western Australia and being near the coast, seeing for me is poor most of the time, however a planetary friend who lives about 70kms north from me and further inland away from the coast is getting very good seeing most nights now when there's no cloud. We have the luxury of waiting for Jupiter and Saturn to reach their highest and often don't start imaging if they are below about 65 degrees unless there's an early or late GRS or transit. Plus if seeing is bad, we often don't image at all.

    My last attempt 2 weeks ago wasn't so great and since this it's been nothing but cloudy nights and patchy rain. You're probably getting more clear nights now than us all the way down here 😄

    This was with the Saxon 8" Mak and Meade Telenegative 2x Barlow, fl 5000, f/24.6, ASI224mc as a comparison. You should be able to get similar Neil with more stable seeing near their highest elevation.
