    A superb Image, which inspires me greatly. Can't wait until my next chance to do some lunar imaging myself ! Regards Steve
  3. Hi, Many thanks for taking the time to provide the excellent explanations and advice. I am sure it will be appreciated by other members as well. Cheers Steve
  4. Hi, I am thinking of getting a Baader H-Alpha Narrowband filter, with the aim of it allowing me to do some DSO imaging with my ZWO ASI 178MC color camera, (ie) to enable me to get some imaging done on moonlit nights. Have been going over previous posts to do with these filters, however I am unable to find what the difference is between (e.g) the 35nm filter, the 7nm filter and the 3.5nm filter. The 35nm H-Alpha filter seems to be the cheapest in the range. Does the filter imaging quality results improve as the number gets lower (ie) is 3.5nm best? I would be quiet happy to go for the 35nm version, to get some experience in using one of these filters. I would be using the filter with my Orion ED80 Refractor. Any advice, or suggestions much appreciated. Regards Steve

    First Moon Images with ZWOASI178MC

    Hi, Just starting to get to grips with my new ZWOASI178MC Camera and took some AVI images of the Moon using the camera resolution (capture area) set at 1600x1200. I then processed through Autostakkert and tweaked in Registax and Gimp. The results look really promising. One of the main reasons I chose this camera was for lunar imaging, so I am very pleased with first results. Below shots taken with my Vixen VC200L. However I intend to use this camera mainly with my Intes MK67 Maksutov , and am looking forward to seeing the results I get (ie) The Intes MK67 Maksutov will probably give me super pin sharp images of the moon. Regards, Steve

    My first M31

    Hi, Very pleased with my first ever attempt at imaging M31. Photo taken with my Orion ED80 Refractor, and Canon 450D DSLR at ISO 1600. Only scraping the surface "exposure wise", I know, with 48 Lights (composed of mainly 60 sec subs, with some 30 sec subs thrown in as well). 7 Darks, 20 Flats ,20 Bias Image processed from start to finish with Astro Pixel Processor (APP), of which I have just started a 30 day free trial. I am VERY impressed with APP, after experiencing lots of frustration with DSS and GIMP. Excited of what may be possible , when I begin to expose for longer periods of time., which I intend to do as a gain more experience. Regards to all Steve

    Mars is mocking me

    Don't worry you are not the only one suffering from "Mars Anxiety Syndrome", I have got my neighbhour's conifer trees to contend with. These trees are a real pain in the neck, I can tell you! (they ruin most of my Saturn opportunities as well). The problem is that Mars is so low in the sky, and with westerly Atlantic winds and atmospheric turbulance, all put in for good measure, if you are able to get in some imaging of the red planet, you are likely to be highly disapointed when you process your hard work. Like has happened to me a lot lately. Never mind, there is always Deep Sky to turn to. Oh no!!! The moon is back again........Agh..... Agh!!! Lol Regards, Steve

    First Image using APT

    Hi, Finally got my courage up to try out APT on Thursday evening 19th July 2018. Prior to this I have been on my hands and knees, mostly on wet grass taking my shots using my hand held Canon RS60 type shutter release. Anyway APT worked fantastic! While my exposures were being taken, I was even cheekily nipping back into the house to take sips from my cup of tea! No more strains in my neck, back ache, shaky legs etc. I did my star alignment ( for some reason I find the 1 star alignment works better than a two star alignment) with my NEQ6, and then for the very FIRST time, used my Bahtinov Mask to actually get as much precise focus as possible. To do this I used the "zoom function" on APT to get a close-up view, to help me set my focus. It worked perfect. I had not been able to do this previously, before I was just looking through my Canon 450D camera eyepiece and hoping that best possible focus had been achieved. (mostly I failed on this, and wasted many evenings). Hopefully those days have gone! APT seems easy to use, and next time, I am now thinking about "Setting A Plan" in which I believe one can pre-set how many exposures you want to take for a given object. However by doing this, could it have a negative effect on heating up my camera sensor? Will I be able to set (ie) a 30 second pause between exposures, so to prevent the camera sensor warming up too much? I Cannot wait to get out again with APT. Using APT, it was so good to be able to view what my last image taken "actually looked like", ( just using the camera screen was a nightmare ), before, I was on my hands and knees on wet grass, struggling to see if the image I had captured was any good. Hopefully APT will now help me improve my Astro Imaging. Below photo - M57 The Ring Nebula. Vixen VC200L and Canon 450D, via APT. Exposure: 1600ASA. x19 1 minute subs and x1 Dark. Put through DSS and then GIMP.

    Some Moon Images from June 2018

    Hi, Also going through my backlog of lunar images from June 2018. Here are some of by best images so far. Only using the most basic Altair Astro GPCAMARO130C, but this little camera, I think, gives great results. Photos processed through Autostakkert (using x1.5 Drizzle), tweaked slightly in Registax and then GIMP. Photos 1, 2, 3 and 4, all shot with the GPCAM through my Intes-Micro MN56 Mak Newt telescope. This scope gives pin sharp views of the moon and is fast becoming my favourite imaging scope for the moon. It absorbs a x2 barlow very well, without image breakdown. Photos 5 and 6, taken again via the GPCAM, but through my largest scope, my Vixen VC200L. Again the Vixen gives stunning views (once fully cooled) and is a good telescope for Moon Imaging. Regards, Steve
  11. Hi, A few of my Saturn Images shot during the end of June 18. Saturn was very low in the sky at the time, heatwave weather, and as I shot the images it looked like the planet was bubbling in witches soup, due to the warm turbulance. Images one and two shot though my Intes-Micro MN56 Mak Newt. Images three and four shot through my Vixen VC200L. Camera: The basic Altair Astro GPCAM ARO130C AVI's run through Autostakkert, saved as Tiff's, tweaked in Registax and then GIMP.

    Recent Imaging Results and Queries Please

    Many thanks for taking time to give me some advice, much appreciated. Thanks, Steve
  14. Hi, I have recently processed images of a small section of the Chain Cluster in Virgo (see the image uploaded) after selecting the final choice in Deep Sky Stacker (DSS) of "Non-Embed". I am aware that for the final saving in DSS, it is recommended to opt for "Embed" and afterwards "pull out" the image details using the "Levels tool" (I am using GIMP). However when I try to process my images after selecting the DSS final "Embed" option, and via GIMP, things start to go downhill ! My finished images have reddish/pink blobs within the centre of the brighter galaxies, and stars. (see image of this problem). What causes this? I reverted to the DSS "Non Embed" option, because by doing so, it got rid of the reddish/pink blob problem. The main image that you see is from 45 (1 minute) light subs and x1 (1 min) Dark. Note: The processed images in which I encountered the reddish/pink blob problem, I had applied 45 (1 minute) light subs, x7 (1 min) Darks, x13 Flats and x13 Bias (the 1st time I have ever tried doing lights and bias frames). What I would like to know please (finding an answer to this online, seems impossible) is if one shoots say 45 Lights, then how many Darks do you need, how many Flats and how many Bias? Do I need to be shooting MORE Light subs before I even begin to think about adding Flats and Bias frames? Regards, Steve
  15. Hi, Photos of Jupiter taken last week using my Vixen VC200L telescope, using an Altair GP-CAM ARO130C Camera. I am a bit out of practice, as they are my first Jupiter pictures this year. Must admit it is now a more relaxing experience taking Jupiter photos with my new NEQ6 mount because last year I was on my hands and knees nudging the telescope by hand to shoot my Jupiter photos using my old Vixen GP Mount with no motors! All photos shot as AVIs and processed through Autostakkert, tweaked in Registax and then GIMP. Regards, Steve
