  1. Excellent detail Greg! Always stunning seeing insects in Macro. So much too see in hairs and scales and veins.
  2. Canis Minor

    Beautifully sharp image! Canis Minor has always fascinated me in the sense that how did they see a small dog in 2 stars. It is probably the constellation that least matches its name
  3. For an opportunity at a very interesting Image, Comet 7p/Pons-Winnecke will be passing right by the Helix Nebula on Tuesday and Wednesday nights (15th. 16th June 2021 Aussie time). It would make a fascinating photo with both in the frame. I'm definitely going to try for it if this damn cloud goes away! Here's a Cartes du Ciel map for Tuesday Night Aussie time:
  4. Great Image Opportunity

    No Ray, we were clouded out both nights the comet was next to Helix Another lost moment.
  5. Yep, that well known Company 'Vixen Optics' is shutting down. Plenty of stock at discount prices. www.vixenoptics.com/Default.asp Apparently Vixen Japan is looking for a new distributor.
  6. Removing Noise

    Ray, I use the 'Camera Raw Filter' in PhotoShop. It's under 'Filter' in the menu. In the image below I have circled the Noise level settings. I find it works best for me if I do Colour noise reduction first, then Noise Reduction, then 'Sharpening' last. What I like about Camera Raw Filter is that you can raise Sharpening without re-introducing the noise you just reduced.
  7. M87 Jet!!!!!!!!!!!!!!!!!!!!!

    Thanks Greg, at least I now know what EPOD is It's strange they didn't call it ESPOD Well done! Ken
  8. M87 Jet!!!!!!!!!!!!!!!!!!!!!

    I see the jet in his photo Ray LOL! but I don't see any photo or link in his last post to EPOD (whatever EPOD is. I've heard of APOD but not EPOD)
  9. M87 Jet!!!!!!!!!!!!!!!!!!!!!

    Where? I don't see anything Ken
  10. 1st Images from my new 450d

    Here's my first attempts stepping up from my 350d to my new (well, new to me) Canon 450d after a 12 year break from using DSLR's Tarantula Nebula (NGC2070) and surrounds in the LMC 3 x 120 second lights stacked in Sequator Processed in PhotoShop CS5 (Exposure slightly raised, black level reduced, and saturation lowered) Focus was slightly out but I'm pretty happy with this first result
  11. Street Lights For and Against

    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
  12. 1st Images from my new 450d

    Thanks Tim, No, my camera isn't modded. I considered it but went against it. I prefer the colours from the unmodded camera. I have used several modded cameras but still prefer the results from unmodded. I only do my DSO imaging at ISO 800. So much easier to process any noise out. I have used 1600 a couple of times as a test and was very disappointed with the results. But I find that planetary video looks OK at 1600 Ken

  14. Street Lights For and Against

    Ray, I can't remember which sites I quoted each time I approached council but there was a lot of them. It was a few years ago. The internet is full of information to assist us in fighting light pollution. I googled all the ones I used by searching for papers on subjects like: Light Pollution, streetlighting effects on wildlife, Light Pollution causes breast cancer, preserving dark skies, etc But also be aware, I was given some great info from council staff that at council meetings they don't really listen to facts about how we can't see stars, or how it is damaging our hobby, or that possums can't sleep. They will say these are important to them (just rhetoric). What really makes them consider reduction, or controlling further development is when you speak Dollars! Show them proof that they can save a LOT of money annually on their streetlighting power bills and then you've got their interest. That's what finally helped us. There are figures on the net showing how much less power the LED streetlighting uses. It is such a major difference that councils all across Victoria have switched over. They have take down the old power hungry streetlights and fit new LED lights. You will hear astronomers across the world complain about LED lighting because it is brighter and their wavelength is hard to filter out for astrophotography. But they hadn't done any tests with the actual lights in place. They only read specs. Why LED lights are far better for us (besides council saving big dollars) is that despite their brighter light, and multi-wavelength spectrum, they are shielded! That means that although below the light is brighter and multi wavelength the light only goes down, not upwards into the sky as most lighting does, and after many teats we don't have ANY problems with any multi-wavelengths because the light doesn't get up to the sky. At our Clubsite/Observatory our sky has gone noticably darker since the new LED lights have been fitted and we have a streetlight right out front of our observatory. Photos show a major difference. This is the streetlight out front of our Observatory. Notice how far up the trees (and sky) the 'before' light goes, compared to the light cut off completely half way up the trees and the darker sky in the 'after' pic:
  15. Street Lights For and Against

    It's a tough task Ray, getting reduced lighting is a BIG movement worldwide by several organisations and it is taking decades to get anywhere. One of the main excuses councils, town planners, communities, and businesses use is the feeling of safety and security, which has now been proven to be the opposite. I totally understand the necessity for lighting along dark pathways and back lanes for personal safety, but almost all lighting worldwide is poorly designed and implemented. With correct lighting design we would ALL see the sky, anywhere! Some of the organisations attempting to make a difference are: Australian Dark Sky Register (Australia) Australasian Dark Sky Alliance (Australia/NZ) International Dark Sky Association (Worldwide) ANPCEN (France) Astronomitaly (Italy) CieloBuio (Italy) Niue Dark Sky Initiative (Nuie) Campaign for Dark Skies (UK) Canadian Geographic (Canada) National Dark Sky Week (USA) Cheers, Ken
  16. 1st Images from my new 450d

    Yes Ray, EOS Utilities requires a computer. It is the capture software that comes on the Canon camera disk. It's very basic but works great. Obviously there are better capture programs, but they cost money . . . except ImagesPlus which is one of the best (if not THE best) capture software but it is verryyy complicated. The author/owner of ImagesPlus has retired and made if freely available now instead of the old price of $279 Personally I find BackyardEOS far better and easier to use and only cost AU$50 for the Premium Edition (link) Yeah, 450d is a great camera and plenty go cheap. Look HERE
  17. 1st Images from my new 450d

    One of our club members has a fantastic little portable kit using a DSLR. Fortunately older Canons that are more than adequate are very cheap now. My 450d was only $310 on ebay. There's plenty more on ebay. He has his 450d mounted on a Skywatcher Star Adventurer tracking mount. He is set up and imaging in about 5 minutes, and pack up takes him about 3 minutes. No fancy software, he just uses the Canon capture software that comes with the cameras disk. (EOS utilities) He gets the same results as us with our fancy gear, but his is so basic. Ken
  18. SW Black Diamond 120mmx1000mm Refractor

    Ray, there is interesting statistics available now after a 20 year research study into security lighting worldwide. It shows that areas with an abundance of security lighting and streetlighting have higher crime rates and burglaries/break-ins. Areas that added to their lighting to feel 'safer' had their burglary rates skyrocket. The reason is because burglars can see what they are doing. Lighting helps burglars. In dark areas burglars have to use a torch and people see the torch light moving, and they often make more noise. Hearing or seeing this people call the police. Also, too much lighting has now been proven to cause cancers, especially Breast Cancer in women. The human body MUST HAVE several hours of total darkness to stay in balance. In some research they found that even the slight bit of light from an electronic clock next to the bed can be enough to disturb the body's circadian rhythm, weakening the body's immunity. Lighting at night has many problems and hardly any benefits. There's a lot of info available on the internet now to use against council (and industrial) lighting. But this subject is for another thread. Not for this one about Skywatcher 120mm refractors

    Thanks Greg Cheers, Ken

    Thanks Ray. No mate, no DSLR tracker mount. I'm still using the same setup I posted a year ago (the DSLR is in the 6 inch reflector) In this link:

    Yes Ray, beautiful dark skies here. We have an agreement with our council (and I have it in writing) that any further development in our town has to be passed by our Astronomy club after the developers and the Electricity company consults with us. If we say no to any streetlights or obtrusive external lighting (which we obviously would do) then they don't get their streetlights or lighting Our council is good at working with us to keep us as a Dark Sky Town on the Australian Dark Sky Register. http://www.australiandarkskyregister.com/
  22. SW Black Diamond 120mmx1000mm Refractor

    Yes Ray, we have smokey skies every day and night for the last few weeks. DWELP is doing their annual burn-offs in the bush across our whole region and farmers are burning off their crop stubble. Gotta love living in the country We just keep imaging and looking through it or we'd have to go on sabbatical for 3 months And now with the cold weather coming we are entering Fog season. We get fogged out at least 2 nights a week on average right through till about mid November.

    Thanks Dave. I'll get used to using DSLR's again, with practice. The last 12 years I've been doing Video Astronomy with Analogue and USB cameras, but now dabbling in both. Video and DSLR's. I'm happy with my results so far
