  1. I have been mulling this for a while now and finally bit the bullet and bought a Pegasus Astro Pocket PowerBox Advance.  This powers the mount, camera, filter wheel, focuser and mini PC and makes wiring very straightforward.  

    I have also just bought one of these

    Bison BATTERY BOX CARRIER WITH USB CHARGER, LED METER, BREAKER & 12V SOCKET : Amazon.co.uk: Electronics & Photo

    So, car battery in the Bison, 12v cigarette charger type lead from Bison to PowerBox, PowerBox to everything else.  Job jobbed.  I have a little wifi travel router thing so can hook into the mini PC to control it via Remote Desktop. 

    So, process will be.  At home log into mini PC and using NINA create the imaging sequences I think I'll go for that night and save them.  Then, at the field set everything up and then using the iPad, hook into the mini PC and load and run the imaging sequences.  I do have full control from the iPad so can change targets etc if necessary however it is a little bit fiddly just due to lack of keyboard and small screen but perfectly manageable.  But the more I can do at home the better in the initial set up the better.

    The Bison will easily hold a 70A battery however mine is only a 40A but even then I'll get a good few hours imaging or observing.

    Any thoughts of adding a longer dovetail bar under the existing one?
    Preferably one with the slot for the mounting screws [assuming the existing dovetail has some threaded holes in it] then you could 'slide' the rig up and down accordingly. I do this with my 're-modded' ETX105 when it is rear-end heavy.
    Apologies... I don't have an image of it to show at the present time.

    Yes - funny you should say this as it just occurred to me after I posted I could look at a longer dove tail.  That said some form of weights would likely be cheaper!.  Good quality Losmandy bars are pricey :).  It is probably the correct solution though...

    I was chatting with someone recently about this who posts on various platforms. Facebook, Twitter, Flickr etc... all use different methods of compression so that their pics load faster, so there is a difference in how it gets presented.

    I ve found Flicker posts darker images, than Twitter for example. No idea what Astrobin is doing.

    Tom

    Astrobin has it right.  It is SGL that has a fondness for dimming my jpeg files for some reason :)

    One of the technical guys on Admin, maybe? Grant, perhaps? I'd double check that the same copy was sent to both sites, though.  Is your colour profile sRGB?

    Olly

    100% the same image and when I post to Facebook, even through its horrible compression at least the brightness is correct.  I have noticed this also when posting IKO competition entries and stuff as well.  My monitor on my workstation is fully calibrated so I know what I have on my screen is correct but then whenever I post here it dulls.  I am not for one minute suggesting any of my images would win any competitions but I feel at an unfair disadvantage here as I need all the help I can get :D

    I wondered if this might be an illusion created by the colour in the rest of the page but, no, your SGL screen shot is indeed darker. Here I copied one onto the other (Astrobin over SGL) and deleted a square from the middle of the AB image to reveal the SGL.

    I've no idea why this should be happening and I don't think it happens to my own images because I'm very fussy about background brightness.

    Olly

    Thank god it's not just my eyes.  It happens to all my images and is a bit annoying as I try and optimise them!  Do you know to whom I would raise this with.  And many thanks for taking the time to compare them :)

    How about if NASA uses Hubble to take an image of webb, at least the back of its sun shield, if anything.

    Would Hubble show anything useful though? JWST would still just be a small dot as Hubble does not have the FL or resolution I don't think to produce a detailed image of a small satellite some 1.4m km away from it.

  7. I captured this data last March and didn't really think I had much there as it is only 50 mins each L, Ha, SII and OIII.  It was also before I even owned a Bahtinov mask and was manually focussing using the gloriously over-engineered focus mechanism on my TMB 105/650 LZOS which is an utter joy for visual use but a bit agricultural for AP.  As a result the image is a little soft.

    However, it is my first full NB image and having worked the data in PI and then Affinity Photo I am happy enough with the end result to share it.  Certainly if someone told me two years ago I would be taking photos of DSOs like this I would have been very happy indeed.

    And it gives me a useful base to look back on and see how I have progressed in the hobby.  I will be revisiting this target this year for sure as well with a view to improving it a fair bit...

  8. Well I've got my little diary started.  I just used an Excel template for a month to a view calendar that allows a little of text to be typed into each day field.  I have 4 colour codes - green = clear and did something, orange = clear and didn't do anything, blue = cloudy but did something astro related (say worked on getting software running smoothly or serviced some kit etc) and red = cloudy and didn't do anything.

    Then I have just typed in a few words about what I did (or didn't) do on each day.  I will try and keep this up for the year now and hopefully it will give me a record to look back on :)

  9. Your amp figures look out to me. 6A for an ASIAir? A Pi4 only draws 3A max that is under heavy load and will often run happily on 2A.

    3A for a guide camera and 5A for the main camera seems incredibly high as well. The guide cam I would have thought only draws milliamps and OK my camera is a Starlight Xpress with a small CCD but even with the cooler and two fans running full pelt barely draws an amp.

    That said a 5A power bank isn't huge and I would have thought you'd get 2-3 hours from it - once up and running and slewed to target is expect you to be drawing 2-3 amps per hour. 

  10. @malc-c - yes this is absolutely the case unfortunately. There is no direct contractual relationship between your CC company and the the supplier therefore S75 does not apply to disputes regarding receipt of goods etc.

    PPs own buyer protection may well kick in however it is not entirely nailed on that you'll get your money back from it. In this case I think the buyer would be outside the 180 day time period to raise a dispute...

    If they had used Paypal, and it was linked to a credit card then yes they could possibly have some form of redress under the credit consumer act and get their deposits back.

    Sadly not and whilst slightly OT worth explaining for anyone paying for anything on CC.

    A quirk of Section 75 is to whom your contract is with. If you use a CC via PayPal then the contract, as far as S75 is concerned, is between you, your CC company and PayPal. 

    Assuming PP then forward the funds on to the end supplier they have fulfilled their contract to you and you have no rights against the end supplier under S75 should goods not turn up etc.

    So, you are always better protected if possible, to pay the supplier directly with CC.

    Clearly this isn't an option with HOUK however of course. 

  12. Ooo I like this idea as last year I was convinced it was cloudy every night expect 21 June which was also a full moon of something 😅.

    It somewhat dampened my enthusiasm and perhaps keeping a record like this will show me we do have decent nights and that it is I that does not always make the most of them. 

    Might knock something up accordingly :)

  13. Looks like it's going to be a beautiful clear night here in subby Sheffield however I have just tried to walk to the garage to get my tripod and PSU and very nearly slipped and fell.  'Tis like an ice rink out there!

    Discretion being the better part of valour and all that I am not going to chance carrying heavy and expensive kit about regardless of whether it means missing a night!  I value my telescope and neck more than that (and in that order too :D )
