    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.

  4. 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.

    95 x 30 seconds, ISO 1600, 50 darks.

    Stacked in Sequator, edited in PaintDotNet.

    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.

  6. 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.

  7. A couple of areas captured near each other with a heaps of varying features. Taken on the 11th of July from Mandurah Western Australia.

  8. Centaurus A Galaxy NGC 5128 aka The Hamburger Galaxy captured on the 18th of March last year with an 83% illuminated moon, conditions average to poor from Mandurah Western Australia. This is my second attempt at this galaxy, this time with a 6" achro frac. The first attempt was terrible with my previously owned C8i on it's alt az mount. I did have some slight drift and getting good collimation seems to be elusive with this older refractor. It also gives bad blue rings around brighter stars which is very annoying and difficult to get rid of.

    I've only been doing DSO astrophotography seriously for about 18 months when the sky allows and I'm no expert at this DSO bizzo but content with my progression so far, I'm always learning new things and enjoying it immensely.

    189 x 30 seconds, ISO 1600, 24 darks.

    Aligned and stacked in Sequator, edited in PaintDotNet and a rework tonight to tidy things up a little more in Fitswork. The second image is a 75% full res crop with less editing to try to bring out some central detail that's usually washed out.

    Thanks Dave, it’s always hit and miss as to whether these HDR combinations turn out ok or not for me :) 

    Ha! funny you should mention that Scoot. I tried HDR for the first time on my Sony a5000 to try and get Earthshine but camera said No! I think it had something to do with the operator.

  10. Around midnight I captued the 100% illuminated moon with a Saxon 10" Newtonian reflector and Sony a5000.

    Then from about 3am I started on the partial lunar eclipse with a Sigma 70-300mm f/4 - 5.6 zoom lens. I tried a different exposure technique setting on the a5000 called High Dynamic Range with Dynamic Range Optimizer which didn't work out so well. The moon was much lower in the sky and I should've tested these settings before hand but quite please I got what I did. I almost deleted all the eclipse photos as they didn't look that great at full res but it was a last minute decision to put a 4 shot sequence in the corners of the full moon shot.

    PIPP used to pre-process 24 full moon photos, AutoStakkert 3 to align and stack, wavelets in RegiStax 6, edited in PaintDotNet with a final tweak in Fitswork.

  12. There's the 2.5x PowerMate 1.25" Gina which I had for quite a while. There wasn't much difference I found from the PowerMate to my 2x Barlows which I have quite a few of including a couple of ED Barlows although conditions here aren't often great, plus I think the planets are very low in the sky for you there and will be for some years. You won't see a vast improvement, it will be minimal at best. I ended up selling my 2.5x PowerMate recently as it wasn't getting used. I'll just stick to my better quality Barlows for when seeing conditions are good or better while the planets are high in the sky here in Australia or not bother with them at all. I can not justify the new prices of them. If you were to buy one try and pick up a nice used one, at least then if you're not happy with it you can re-sell it and get your money back.

  13. Jupiter at 9:48pm last night. Conditions good Mandurah Western Australia. Finally some decent seeing! This is the best I've captured this season from the South West of WA.

    Captured in SharpCap, Stacked in AutoStakkert 3, wavelets in RegiStax 6, edited in PaintDotNet.

    Image was resized in RS6 to 200% with the Mitchell filter, edited, then reduced to 80% of that size. I find this much better than using Drizzle in AS3!

    The second image is only a 2 image gif to try and work out what's noise and what's actual gas cloud detail and gifs are not the best way to show this. Each image was about 197kb in size and the two image gif is now 99kb. I'm rethinking my capture settings to try and get the best faint detail while reducing noise. I've dropped gain on the non cooled 224mc to 180, adjusted exposure to around 60 frames per second and dropped the time of the recordings to 2 minutes instead of 3 minutes.
