  1. Just a thought regards earlier post about the camera/usb possibly playing up...

    I used to use a 550d modded with a 130PDS on an EQ3 Pro a few years ago before I sold the lot to help with costs of our wedding but before doing so and after some frustration with the camera conking out randonly both when just connected and also whilst usong BYE, I discovered that when using a 10 metre USB extension cable for some reason the distance to camera seemed to lower the signal/output and after I replaced it with a usb cord with 'signal booster' attachment (still really cheap on fleabay) the problem immediately went away.

    Worth a try??!


  2. I always found trying to focus with a DSLR/lens very finnicky. I also found that setting the lens to 'infinity' very often was not 100% accurate.  Best advice I can suggest is turn AF off and just use manual focus, set to infinity and be prepared to adjust the focus ring a tiny amount each time. I once used a 70-300 on a Pentax DSLR and ended up making my own Bahtinov mask to achieve focus but even then it was a faff.  You might struggle with an 18-55 unless you can zoom right in on live view?

  3. Hello all.

    As a lifelong stargazer and previous participant in the great halls of SGL, I have returned to the fold and very quickly encountered an 'issue' I'm hoping to get some kind advice on please??  So firstly...hello again everyone.  It's nice to be back :)

    I took a couple of years away from this brilliant hobby fully intending to get back in again when the time was right.  Well, in January I was involved in an accident and had a serious leg fracture. I treated myself to a fairly cheap, but enjoyable Celestron LCM 80 to do a bit of visual from the confines of the back garden whilst mincing about on crutches and one thing led to another...

    I have since added an ST80, all manner of EP's and bought a cheap but strangely enjoyable Bresser Skylux 70/700.  As a previous practicer of the dark arts, I ended up adding a camera into the mix and have taken some half decent 30 sec subs & got some pleasant enough shots of a few DSO's.  

    Now, my problem that I'm hoping to get some tips on is this...

    I've decided to cut the Bresser down a bit. I have an Orion flip mirror (mirror box is 3 inches long) and when rigged up, all is within the weight limit of the LCM but I just don't quite have the inward focuser travel needed to bring the EP/camera to focus. I reckon a bit of careful cutting of the optical tube will do the trick, but my query is this. If I'm about 1" shy of focus with the flip mirror, can I take off 4 inches without ruining the scope?? I'm thinking the length of the mirror box will cancel out the shortening of the OTA and the extra inch will allow the whole thing to focus with minimal outward travel - keeping it stable. I've already cleaned & blackened the lenses and modified the rack & pinion to make it stiffer, more stable and generally better to use. I know there is maths involved but rather than give myself a headache, I thought I'd come to you guys again.

    And before anyone laughs about using the LCM for AP, having been the proud (and sometimes frustrated) owner/user of an autoguided EQ rig before I know what the LCM mount will and wont do, and its surprisingly good fun getting some 30 sec subs with a rig that takes me about 3 minutes to set up and take apart.

    All suggestions welcome.  And it's good to be back.

    Clear skies :)

  4. Thank you for all the kind words folks, it is very much appreciated. 

    I will actually stick around here anyway from time to time to 'keep my eye in' so to speak.

    I also still have my OTA, imaging rig, mount & full spectrum DSLR for sale, so if you wish to have a look, or spread the word that would be good :)  ;) 

    Clear skies ...........

    Sorry to hear you are leaving us, but it is understandable. For many years I was an armchair astronomer, reading books and magazines. Retirement and a grown up family allowed me to return to the fold. I am sure at some stage you will too. Best of luck to you and your wife to be.

    Thanks very much. I most certainly will return to!!  :)

    Good luck Scott.  

    It's a break rather than a goodbye! I gave up astronomy completely for around 5 - 6 years. The interest will come back (marriage will ensure that sitting in the garden on your own will suddenly appeal more) :D, but there is no point forcing you to do something and of course other things get in the way!

    Look forward to seeing you back at some point.


    Cheers Ant. I'm hopeful it wont be too long. I plan on kicking the boy out when he turns 18 and the future Mrs T had a habit of kicking me out into the garden when Holby came on, so it all works/worked rather well.  See you around soon ;)


  7. All,

    It is with a heavy heart I have decided to sell my whole astro kit. Working shifts and normal daytime photography (when I can), and the impending marriage to my lovely better half this coming December dictate that it's time to say tatty-bye for now.  I have listed my stuff in the classifieds for all to nosey at.

    I plan on hanging around still from time to time and checking out the great images posted by the other practicers of the 'dark art' of guided imaging.

    So see you all around and clear skies!!!

    Scott :(

  8. Chris, this is a superb final image.  How on earth do you manage to get 20 hrs worth of clear skies?????

    I haven't managed to get 20 hrs worth of subs since I started out (although working shifts doesn't help).

    Brilliant image, thanks for sharing it  ;)

  9. That is a very detailed image. I think the stars may be slightly too heavily processed.  Maybe a touch less would be good but it might just be the compression on the forum- not sure.

    For what it's worth I agree.  To me looks ever so slightly over sharpened (but I am no astro imaging expert!!).

    However, I do love seeing the veil in wide field.  Looks like it blew apart just yesterday. 

    Thanks for sharing :)

  10. 'Eggy stars' (?!)  Yeah right ;)

    What a stunning image. I had a crack at this  a while back when I first got my TS 65mm quad but alas, got nowhere near the depth of this (although I did only manage about 2hrs worth).

    It's crying out for a mosaic to include the other nebulosity creeping in from bottom right !!


  11. That's a superb image.  I wouldn't worry about the double spikes - they are not that easy to notice really.  Very eyecatching indeed.

    I haven't taken 18 hours worth of subs this year for all my imaging runs combined, so you've done very well with this.

    An image to be proud of I would say!
