    I haven't been able to collect more data as yet due mostly to wind on the few nights it's been clear so I have had a play with what I have available so far. Approx 8.5 hrs total LRGB integration, only a quick throw together in PI . Shane

    Narrowband Image of dust pillars inside the Rosette. Total exposure time 9 hours, Ha, SII and OIII @ 3hr each. Noise removal in PixInsight, colour balance and layer merging in photoshop (haven't got that far with PI yet). Image still needs to be sharpened and stars also need some attention, I'll work through these over the next couple of nights. This is about half the size of the chip at 2x2 binning, so I'm getting some good printable pics for my wall, not to mention good image scale (the C14 goes deep). Worth doing a quick comparison. Click here for a random pic of the Rosette on Google, my C14 FOV only captures what is below, you can see the image scale of the pillars in that photo on Google. So the C14 is resolving great detail IMO. However at this focal length, everything from guiding, collimation, wind, focus is torturous. Comments feedback welcome. Anyone know how to sharpen stars in PI please? Cough, Erhem, Shane, erhem, Cough. Ray

    I am going to start the ball rolling for this Christmas with a photo from my good friend Kerryn Murphy, a very keen photographer and Astronomer. Kerryn holds all rights to this photo. Having said that may I wish everyone on the Forum a very happy Christmas and Great New year from Perth Dave, Valentina and Mark. Image of Fir tree topped out by Venus. Great Stuff Kerryn

    Here is an NB image with no luminance added yet. About 3 hours per channel. Took a while to accumulate all the data and I throw away quite a bit that doesn't cut the mustard. I use CCD Inspector on every sub frame that comes in and I make live focus adjustments throughout the imaging run to ensure focus stays tack sharp. I do PA, collimation before every imaging run these days. My pier will suffer from PA drift as well due to temperature changes at the FL of 4 metres, but I'm overcoming all these challenges and loving it. Admittedly once the observatory is open, I do most of my AP from the couch with Teamviewer on my iPhone. There are some beautiful foreground dark nebulae (top centre, left and right sides and lower left) that come out well because of the bright background. I've done this object before in RGB but never in NB and never up this close, but I'm impressed with how active and dynamic the object is. I could still probably tighten up those stars and reduce the red halos but I'm happy with the result. C&C's welcome as always. Ray

    Hi all, Thought I'd give this a go to try a few things as I rattle my brain trying to remember imaging. This planetary is way too small for my set-up. I know it's not centred and far from great, but I just wanted to check the edges of the image using a basic star field with a bonus small object. Plus I've never looked at this object either. I'm going to try my 0.85x focal reducer to see if it helps or makes the edges worse. At least the guiding seemed to be alright. Dan

    Hi all, Been a long time. New hobby of fatherhood has been consuming. But anyway...trying to get back into it. Here's my first attempt for ages. I've discovered a few issues. My memory for starters. Plus a bit of focal tilt. Got some time off work to sort out though. Sorry - Not sure how to upload a better quality pic either. What's the max file size again? My original sizes are approx. 350,000 KB. Talk soon, Dan.

    It's been some time since I have visited (something like 4 years or there abouts). I thought I might post one of my recent images of the Eagle Nebula. Taken in NB and RGB wash. Only 12 hours in total but acceptable levels of noise in my opinion. Click here for large resolution image.

    Planets. Finally, a 'sort of' clear night. Started off shortly after sunset with a nice view of our Earth's shadow projected onto the atmosphere. Then was able to revisit Jupiter, Saturn and Mars. Not much detail on the side of Mars that was facing me at the time due to a very large dust storm currently in progress. Cheers, Tim.

    Finally had some clear weather. I was so out of practice when I started these (and a few glasses of wine in) I completely forget to take notice of my histogram on my first run of Jupiter, so rather than embarrass myself, I will only post Saturn, Mars and Venus (and not in that order). Hopefully tomorrow night will be clear and I'll do some more. Each image is approximately 500 frames per RGB channel (I should take more notice of that). Regards Ray

    I think it has something to do with the Moon being upside down at your place Greg

    Only 4 x 30-min subs so tons of noise, and I can't use statistics to get rid of plane trails when 2 of the 4 subs has a plane on it However, what this does show me is that if I ever see a clear sky again I need to get a lot more hors with the 200mm lenses on this region. Greg

    When I was in the Norfolk County Constabulary, (1957 - 1968) standing outside the Norwich Gates at Sandringham House for 4 hours at a time and within the grounds, surrounded by 6ft drifts of snow it was not amusing, especially when the Superintendent in Charge of Sandringham Division (Lt Col R B Mitchell) drove up in his heated car, winding the window down and saying ..."But think of the honour chap!" I spent 9 Christmases and many other occasions at Sandringham House being one of the "honoured" chosen few. Dave

    Clear from 7:30 until 9:00 p.m. last night, intrusive Moon, so went for Ceres. 18 x 15-minute subs from the Sky 90 array. Will go for this again tonight if it is clear even though the Moon will be even worse. Greg

    Very quick and very dirty process of current target, NGC 1365. approx 9hrs integration RGB. Still need Luminance data but needed to see progress as I haven't done any processing for a while. Shane

    From 15/02/2018 here are 36 x 10-minute subs on the Sky 90 array of beautiful blue star Gomeisa (Beta Canis Majoris). The averaged data shows a nice bright asteroid near centre (not visible in this SDMask stacked image which is used to get rid of the hot pixels). Greg

    It just doesn't get any better than this for my locale. Almost, got the Enke division. I may try stacking less frames just to see if I can get a little more detail. Same image, just displayed differently. With the ZWO ASI120mm. Tim.

    Joke right? No such thing as a digital sundial, or is there? Just 3D printed out this little beauty. Shows 10:20 when it was actually 10:23 and shows mid-day when it was spot-on mid-day. Resolution of the sundial is 20-minutes with the printer at its highest resolution of 0.1mm. Greg

    I spent the evening up on Hergest Ridge in Kington Herefordshire again last night as the weather was good. I knew that it had been raining up there earlier in the week and I was hopeful that there were going to be some pools of water to catch some reflections from the stars during the time lapse. I found one pool which is where I set my Sony A7Sii and Tamron 15-30mm f2.8 zoom lens on my Rhino Camera Gear Evo Carbon slider with motion and arc. I shot two short time lapse videos during the night shooting a total of over 700x30 second exposures with the zoom lens at the 15mm setting and f2.8 and at ISO 25600. Although it was quite breezy the water in the pool remained calm allowing for some nice reflections. In the second clip the very bright areas are from the light pollution in Leominster and Kington The video can be seen at the link below and is best viewed in at least HD Best wishes Gordon

    I've got heaps of reptiles where I live. Mostly good ones. But every winter I have to save many of these marbled geckos in my firewood. My little daughter and I gathered quite a few on this occasion and relocated them to another old tree stump with lots of hides and moisture. They are slow and sleepy this time of year. They are so cute. But have to be careful as they drop their tail in defence. I was told their tail is the source that gets them through winter without the need to eat. Summer is a completely different story. So many jacky dragons, lace monitors, brown and black snakes and even turtles, yet, hardly see these geckos.

    Carbon star in Taurus. 5 hours of 10-minute subs with the Sky 90 array. Greg

    As I had the full 11.5 hours for IC2087 it made sense to remake the 2-framer with the 10-hour frame to the right. So the new process Taurus Molecular Cloud image - all 21.5 hours of it - now looks like this. Greg

    Captured a decent Saturn despite the high humidity we've been having. Used both of my cams, this time the ASI120MM won out over the Skyris. Tim.

    And here is a video of the 10 p.m. ISS pass last night taken with the Canon 5D MkII and a 15mm fisheye lens. Couldn't take any stills of a few seconds duration as it was far too light. The ISS will be clearly visible to the centre right about 1-minute in. The ISS exits top left. Turn off the annoying audio

    Nice one ! I have been watching them getting closer, but timing was all wrong at night so missed out. Nights getting cooler here and not conducive to crawled out of the sack !! Dave

    Finding guys that will do small one off jobs are becoming very scarce. I had a mate at Willeton (next suburb) who had a decent sized CNC machine and he did a number of mods for me for focusers and scope adapters. But they jacked up his rent so high they put him out of business and he went back to being an employed CNC machinist. I think he sold his CNC to the company he went and worked for. Even hard to find a GP Welder, had one of those at Willeton, same routine, rent increases and he took off back to New Zealand. Yeah, Willeton used to be great area for small business, but the property owners got too greedy and now half the properties are empty. I have all the parts etc to build a small CNC machine, I need a round tuit and enough enthusiasm to build it. We also have a small MIG welder here which I used to build rotator cages for my ham radio masts, they went reasonably well. Dave

    An extremely quick process of last night's data (I didn't even remove the plane trails) as I was itching to see what I'd caught. 18 x 40-minute subs (yes that's 40-minutes!!) using the Sky 90 array. It brought out more of the faint stuff in the area than I have managed to get before with my kit Greg

    I did a pretty crap job of putting the two 200mm frames together (IC2087 and SAO76573) to give a 2-frame mosaic, so you will have to wait until Noel Carboni gets around to looking at this one for a decent image. But the crap job is here below Greg

    From the album Paul C Swift

    Finally complete after seven nights of photography: Sh2-119 the defuse emission nebular in Cygnus only a few degrees away from the North America Nebula. The object consists mostly of hydrogen, with some sulfur-II and faint amounts of oxygen-III. This is a two panel mosaic.

    I need to brush up on my narrow band imaging processing (more like learn how to do it). This is 40 minutes each through Ha, OIII and SII. I've tried to reduce the star bloating in photoshop a bit. I'll gather more data (once these storms clear again Shane!), and keep tweaking the final product. Overall, I'm happy with the result considering how out of practice I am. I've got a luminance channel to add to it later. Feedback on reducing star bloating and removing the red hue from the background (and anything else) welcome. Ray

    Most, (I think) are feeding their egos on FB. Almost no one explains the images they post, people who know absolutley nothing about what they are looking at are 'ooohing and awwing' their pics like they work for NASA. Everyone's an expert, noone offers suggestions to the poster on how to make their images better, details are non-existent on what they did /used, I could go on and on with my personal OP, but somehow it seems counter productive. I like this site, (the much needed remodel especially.) I like the current 'active' members and I will continue to post, comment/contribute and be an occasional pain in the arse. I get around to several other 'genuine' astronomy forums, (mostly lurking) but I've also noticed a fall off in posts in general (by date/time etc.) nearly everywhere. Tim.
