    Been a while since I posted a photo, but having some spare time has allowed me to process some data I have. This was processed mostly in PI and some minor adjustments in PS. Shot at 4000mm, Focal Ratio F11, and probably spent about 50 hours acquiring the correct subs. The total imaging time used is more like 10 hours, but this object sits over the city lights from my observatory and many subs were unusable. C/C's welcome. Ray

    Walked outside last night about 11pm, and noticed this action going on. It was cloudy earlier, so I didn't bother trying to do any imaging. But anyway just a quick snapshot a Mars and the Moon hangin together. Tim.

    Playing about on Photoshop 2020 I put together everything I had on the Pelican nebula and then also added DSS data from the same region. Everything stitched together using REGISTAR. Greg

    I combined all my Sky90 data of this object together with the DSS data from the same region. Barnard's "E" is a dark nebula lying close to the star Tarazed. How many stars do you think are in this image?? Registar says there are 165,000 Greg

    I took this a few months ago, but I need to add luminance to it. The weather hasn't been cooperating on my nights off. First image in a while, but figured I should post it to prove I am still alive. The image is grainy and needs star reduction and a few other things done to it, but it is headed in the right direction. Ray

    Found an SD card with a few shots from the 10" / EOS 500D. And went thru them in PS. I think this one is worthy of pasting here. A rare occasion where the focus is reasonable and terminator clean. Currently its very hit and miss to find a break in the perishing cloud over W.A. Plus the temperature is not conducive to elevating myself off the electric blanket ! Cheers Dave.

    Hi For those that have been interested in my astroimages and time lapse videos, I had a website called "Imaging the heavens" Unfortunately the hosting site has announced that they are "pulling the plug" on June 30th and will no longer be hosting any websites so I've been having a go over the last 4 days at building a new website using Wordpress and Elementor and have managed to get something up and running, it will have a new name but the theme is largely the same ie night and astrophotography. It is called "In the still of the night". It is largely finished now apart from a few tweaks or possibility of extra pages in the future. If you'd like to have a look at how far I've got so far it can be found at the link below. There was no ".com" available but I did get a ".space" which I thought was very apt https://www.inthestillofthenight.space Best wishes Gordon

    lol, I know, I'm just looking for the easy way out, but its time to clean them anyway. I have had a long hiatus from AP (work, study, family, broken observatory computer). So I am looking forward to getting some photos right after this full moon goes away. I am thinking Sombrero is well positioned at the moment. Ray

    Same here Greg. I have heard some drunks talking loudly as they were walking home from the pub at about midnight probably 3 times in the 20 years I have lived here. Being out in the country we don't even have footpaths, so what do we need streetlights for? Ken

    As someone who is up all night and sees what's going on - the only thing the street lights help at 1 in the morning are the foxes to find their way home. I have never seen anyone walking around at that time. Greg

    Great captures Ken. Is your 450D modified for AP, or just using the stock filter? I modified mine myself (450D) installing a IR pass filter. Lets in the Ha wavelengths. NOTE: The noise gets rough on exposures above 5min @ ISO 800. 1600 is worse, unless you're shooting say, a comet using 1min exposures. Glad you like it, Have fun and experiment! Tim.

    Thanks guru. I am going to see if I can get my council to turn lights off a few nights a month (around new moon time) to save energy and assist kids with learning the sky (a forgotten art). Ray

    Those of you used to seeing my work may think (at first sight) that I've lost the plot with this one. Got out for the first time in MONTHS last night and did an hour's worth of imaging with the Hyperstar III on the C11. 12 x 4-minute subs of M87. Processed using the Digital Development Filter (instead of a bunch of curves) and I managed to pull out the JET!!!!! May look unimpressive - but I am really happy with this one Greg

    Hi Ray, No inversion or colour manipulation, just a bit of careful processing with the DD filter and some curves at the end to reduce the overall brightness a LOT. Greg

    Hi Ray & Tim - thanks, & good to hear from you two! I was thinking of you two (& Shane) when I dropped in here yesterday...a fairly hot day today & I've replaced the wheels with new tyres on the van a few minutes back - time for my senior's nap now..!

    Yep - to get the whole thing in it's a 2-framer with the Sky90s, that's like trying to image IC1396 (which is also huge). Greg

    Managed to get Photoshop and all the associated bits onto a more up to date machine (HP Z600 workstation) as my main computer is slowly losing the plot. Did a test process on some Taurus molecular cloud data - 42 x 20-minute subs. Greg

    And, my best effort at the 'Great Conjunction of the Century'. It will still be a good view tomorrow night if one has the opportunity, (and the weather) to have a look. This one is from the 20th. And this is from the 21st. I used the C9.25 with my now old 450da and a 2x barlow lens I fabricated some time back. FOV was about right for this event. Cheers, Tim.

    Before putting Trius M26C OSC CCDs on the back of the Canon 200mm prime lenses, I tried the lens out (for astrophotography) with a Canon 5D MkII DSLR. The results were absolutely superb, and as the 5D MkII is now an "old" model you can pick them up cheap. Greg

    It was one of those moments when almost anything that could go wrong did. New laptop wouldn't recognize camera, had to grab old laptop which hadn't been fired up in months, battery dead in camera, grab more batteries, the old GC-5 mount wouldn't come on, flick switch 57 times, yep that got it! And the result for all that fun filled enjoyment... Ahhh, there it is! Tim.

    Noted Ken, I have a number of Canon Cameras, including film versions plus the last one made by Canon H1n film cam. I have used the range from 350D to the 7D. At Present I have the EOS 500d 750d and 7d. Each have their pros and cons. Basically I judge their performance on the results I get and and personally not particularly interested in what some of the "Rivet Counters" think -- Also there is a lot of bias between brands, each one trying to outdo the other. Over the years I have handled Pentax and Canon film and Canon Digital. I cannot speak of Nikon as I have never used one. but there are two very divided schools between Canon and Nikon. The later model I have of the 7d, I use mainly for Terrestrial use and birdwatching. having a very wide range of EF lens also keeps me to the Canon brand

    Tried it again on the EQ6Pro Mount. - From the Park position landed with the moon just into the eyepiece. Refined the tuning and monitored the tracking and it remained inside the eyepiece (25mm) for 2 1/2 hours with only a slight touch to centre it. Also tried an 10mm plossl. Brilliant. Detail splendiferous. Plus the scope solid as a rock, no wobblies at all. This is a nice piece of equipment. Did something right for a change Dave

    All is good in the world once more, after a trim all looks good with round stars. I tried slightly different temperature settings as well and all still looks good, now I have to wait for our Lunar friend to bugger off so I can get back to imaging. Shane

    Even though I already have flop stoppers on my C14 the mirror still shifts sideways, and not just a little bit, enough to make my astrophotography efforts worthless. Recapping that the problems with mirror flop are poor photos not matter how good the guiding, poor pointing model, loss of focus and collimation. The standard flop stopper config is to attach screws through the rear cell of the telescope which attach to the bottom of the mirror. This mostly only prevents movement front and backwards and will remove a small amount of sideways inertia, but sideways inertia is still detectable. When you are dealing with a heavy piece of glass like the C14 mirror you will still experience some sideways shifting and this is amplified greatly by the awesome focal length of the C14. My solution to this is three M6 nylon screws at 120 degrees apart placed through threaded holes in the rear cell that push up against the side of the mirror holding it in place (very similar system to how we hold guide and finder scopes inside guide rings). I chose M6 screws because their rigidity will increase their holding power. Nylon instead of metal so that we don't chip or scratch the side of the mirror. I was able to use two existing holes and only needed to drill one more. All three needed to be tapped for the M6 thread. I will report back tonight with my results. Fingers crossed. Ray
