  1. Hi Astrogirl

    It's a beautiful image!

    I don't think I've ever seen this one before. What is it like visually?

    When I first saw the image download I wasn't sure whether it was going to turn out to be good enough to post but the more I looked at it the more I liked it, as for visually, I would stand no chance where I live even with seriously big optics and I am not sure how easy it would be to see even from a very dark site with the right filters as it is relatively faint.



  2. Hi Ray

    Thanks for the comments. I think the graininess is a combination of the following

    1. Not long enough for each subframe, may try 20 minute subs next time

    2. Not enough subframes, ideally I like to use at least 20 to help smooth the image but conditions were against me this time

    3. My poor processing skills, I think I clipped the black point which didn't help

    The Paramount ME is better than you can possibly imagine, bear in mind I am still using it straight out of the box, ie no PEC and very basic settings when doing a mapping run. After doing two 15 star mapping runs I can get within 10 arcseconds (within a sixth of an arc minute) of the pole. This takes me less than 30 minutes to do. You can't get that accurate with drift alignment after 2 hours. Richard Crisp of Narrowband Imaging fame suggests I try 20 minute sub frames as the Periodic error of the Paramount is so negligable (as can be seen from the images). How long I can track unguided will depend on the weather ie clouds and how accurate my polar alignment is.



  3. Hi all

    Finally there has been a bit of clear weather where I live, albeit for half a night. I didn't get out till late so I had a go at IC 405 (flaming star nebula) with my trusty Ha filter. As with previous Ha images I used 10 minute subframes unguided. I only managed 6 subframes as it was getting very close to the horizon where there was some cloud creeping up hence the image being quite noisy.

    TMB 115 with Starlight Xpress H36 and Astronomik 13nm Ha filter on Paramount ME unguided, simple autodark subtraction done in Maxim DL, with curves, levels and contrast done in Photoshop CS2.

    There is a better quality image on my website http://www.imagingtheheavens.co.uk

  4. Hi HP

    I like the images, very crisp and plenty of detail, it's nice to see others using monochrome. Sometimes you just can't portray the same atmosphere in an image with colour, especially the horsehead. A lot of my imaging is now going to be done with monochrome + Ha filter (everybody should have one of these in their equipment)

    All the best



  5. Hi Chris

    It is always very difficult when you have two choices that are similar specs and prices. You are quite right with your comment of the G11 being in stock or not. I had a similar dilema when I was getting a new mount as I had originally ordered a Losmandy Titan but there were so many delays I decided to really push the boat out and get a Paramount ME which was readily available and I'm glad I did. Anyway back to your choices, if I was in your shoes I would probably be inclined to go for the takahashi as I have heard that the tracking accuracy is more consistent, tracking accuracy on losmandy mounts apparently can vary quite a bit from batch to batch, this shouldn't be a problem with the use of autoguiding. Also I have heard that some owners of losmandy mounts have reported motor burn outs when using maximum slew speeds with heavy loads.

    Hope this helps

    Good luck with your choice



  6. Hi Del

    Thanks for the comments. This particular nebula is IC 1805 or the Heart nebula in Cassiopeia. The bright appendage towards the bottom right is known as the Northern Bear or Ghost nebula, I can't remember the catalogue numbers for these but they can be checked on any search engine. Beyond the top of this image is another nebula called the Soul nebula which together with the Heart nebula make up the Heart and Soul nebula complex which is commonly imaged with wider field scopes and camera lenses.

    Best regards


  7. Hi all

    I've just joined the forum. I live in Hereford in the UK and although my interest in astronomy has been active over the years I have just recently been seriously bitten by the imaging bug, to the extent that thanks to working a ridiculous amount of overtime over the last two years I have been able to put my current system together which consists of the following

    TMB 115 f7

    Celestron C14 + fastar

    Paramount ME

    Tri-pier 2

    Starlight Xpress SXVF M7C, M8C, H36 and lodestar

    Nagler 31mm and Ethos 13mm

    + odds and sods

    I have only just got the TMB 115 and H36 and have recently got a full set of filters and due to the full moon and light pollution I have been trying out a Ha 13nm filter

    My efforts are below


    This was 8 x 10 minutes unguided, fog stopped further imaging that night


    This was 15 x 10 minutes unguided a couple of nights later, again weather conditions cut short the imaging run


    This was 18 x 10 minutes unguided just as the clouds came in

    All of the images had very basic processing of just a few mild itterations of curves and contrast enhancement in photoshop. I will post more as they materialise. All the rest of my images can be see on my website


    Thanks for looking
