  1.  

    Last night i had front row seats to the best show in town. 
    North Wales has some of the darkest skies in the UK. hence why i spend alot of time in the area.

    There was meant to be a chance of the first decent auroa of the season but it never really came, so i focused on some other aspects of the night sky.

    I had a Sigma Imaging UK 14mm F1.8 on loan for the evening and i was eager to see what this lens could do after hearing great things about it. 

    Nothing could of prepared me for the back of screen moment after the first exposure. What a beautifully crafted lens.

     

    Shot wide open at F1.8 

    ISO 1250 

    4X4MIN

  2. Are you you using a tripod collar on you're 70-200?  I'll be adding a vixen clamp my self just for some more stability.

    I'm not a fan of manfrotto products I think they are over rated I've brokenteo of their tripods and that head you use has failed on me. 

    I found using a heavyweight tripod makes a big difference to my exposure length and an accurate polar alignment. 

    Is you're camera a crop sensor as it will give you 1.6x crop factor vs a full frame sensor and could be the difference between out set ups so you're trailing would be slightly more exaggerated

    Hello,

    Just a small question. I want to use a DSLR on the SA included dovetail without having to remove the quick release plate from the camera. One option would be to atach the whole ball head to the dovetail, but I'm worried about the extra weight. My question is, would I be able to just get a arca swiss plate and clamp from amazon and attach the clamp to the fine-tuning end of the dovetail? If so any clamps you recommend. I have seen some pictures with what seem's to be panning bases doing this job but i'm unsure if they are standard bases or something custom built.

     

    thanks in advance!

    This is how I run mine.  No issues really and I'm getting 300 secs 

    Just for scale this is my tripod no broken backs for PA for me!!

  4. im currently getting back into a bit of WF deep sky stuff. basic rig for now but the idea is to be able to capture data at home as well as from the datk sky's of Anglesey. 

     im looking for a LP filter but im struggling. the only one i can find is the IDAS 67mm that will screw onto the the end of my lens. this is ok but its very expensive. im just wondering if there are clip in filters for Sony mirrorless cameras yet??  it's been a while since ive shopped around for anything imaging wise. 

     

    Cheers

    Good project. Weird how it's soft only in one corner (tilt?) Fingers crossed you get the weather you need, it looks promising but I dare not say anymore than that.

    cheers Chris, yeah its pretty strange i have a feeling its a bit of sag on the bayonet of the sony. It's a problem thats been there from the start. you can however buy a cnc machined new one for about twenty bucks.  its now on order so time will tell if its that.

  6. Im back to having a tracker for the coming season and managed a night out last night to test the gear.  The plan is for this to accompany me on some trips to dark skys and do some wide field mosaic images of nebula regions. 

    im using a Sonya7rii and a sony 70-200mm F4 OSS G 

     

    image details

    70MM 

    ISO 1000

    F4.5 

    x121 seconds 

    im actually quite surprised at how sharp this lens is, apart from the top left which is very soft every other corner is very good.   hopefully over the next few nights i can get my mosaic done of this area around Deneb & Sadr. 

     

    image sequence as follows ::
