    Need help with Fov...

    in EEVA - Discussion

    Posted · Edited by SIDO

    Took this stack under high cloud last night after hacking together a new finder for my static eeva rig out of a 6x30 Celestron Ler finderscope objective a 25mm binocular objective for use as a reducer and an infra red blocking filter, should be 4.6 x 2.6° but not sure I couldent see hardly any stars visible with the high cloud and just took the stack blind on a camera tripod outside while sitting in my kitchen as the low temps last night were more like winter. So target area unknown to me/would like to know. Field of view unknown/would also like to know.

    The original image is 1936x1096 and because its a static livestack png the crop removed the under exposed overlap leaving 1655x1018, I did the crop and a quick edit on my phone to help bring the details for identifcation purposes.

    My system for eeva is static so just like manual visual observing I need a good magnified finder as the laser often only gets me close and this should speed things up. It can also be a fair eeva wide field set up I am discovering and already thinking I could start a stack on it as soon as a target is located then while busy making ajustments to the main scope camera I can toggle back and have a look after starting the main scope stacking application.

    Any help would be great, this is all quite new to me, I know I've chosen methods that are uncommon so please bear with me here.

    Teleportation of humans - will it ever be possible?

    in Physics, Space Science and Theories

    Posted · Edited by SIDO

    It's all about information storage, to store all the individual atom details for every atom and its precise location and type in a human is a massive data storage undertaking.

    One analogy stated it would take our current hard drive technology with a stack stacked to the edge of the Milky Way to contain this information for a single unique human then a processor that could process and realocate all the atoms almost instantly so one would not be bleeding all over the place upon arrival...This equipment would be needed at both the point of tranmission and collection, to do teleportation without collection and reconstruction equipment at the receive location would require a force field with the dexterity to place single atoms at precise coordinates at great distances and if we look at current force field experiments the science is quite unsteady to say the least.

    My understanding is we haven't even yet reached what would be considered the stone age of  teleportation technology advancement, the good news is experiments in teleportation may not bring dramatic results but do indeed reveal limits and new discoveries none the less and are always an interesting read.

    I completed all my out of body experiences as a young man and now just do coffee induced thought experiments instead ?

    What's EEVA?!?

    There are no wires, no computer screens, just a glass objective lens with plenty of eye relief to look through. 

    Its just a highly advanced piece of military technology powered by electricity with circuts to control power used and for photon emitting and collection, just a glass objective lens is quite an understatement ?

    If I look through your telescope we are making observations together, if you take a photo through your telescope and share it with me (like here on SGL) we are making observations together.

    In as much as dedicated imagers like to be described as such they are really just making long period observations were results are far from instant but their intent is to reveal the maximum detail possible with their particular equipment and record their results or observations to share with others...They are indeed Observers in the purest sence, we all are weather it be nv eaa va eeva visual radio spectrometry or any other or weather we have no equipment at all and just look through someone else's or share their observations via images...Comment discussion and learning the likely results.

    Since the new eeva threads have been created there has been a serious uptick in discussion regarding the new eeva forum or in finer terms eeva itself and one of the most interesting reads currently on SGL in my humble opinion, my thoughts here are that a lot of these discussions would not be taking place in other threads had it not been for the creation of the new outlet that the eeva threads provide.

    I'm absolutely sure that some beginner astronomers will learn, benefit and succeed via these new forums as I have done being an eeva novice working towards beginner status, being a long time visual observer transitioning into eeva or specifically va I had some at a crossroads issues going primarily digital verses visual but now consider it just another method for observation but with specific advantages other methods do not incorporate.

    For me the real kicker was observing mag 10 galaxies with a 50% waning moon and high cloud so thick the bright stars in Ursa Major were barely visible all this with a static mount to boot, not like I'm going to head out regularly and observe under skies that bad but it does speak to the awesome capabilities eeva can bring to bear.

    After reading through this thread a couple times now I thought it was time for my two cents...

    What's EEVA ?!?

    EEVA is Awesome...

    Aperture Fever!

    My biggest scope was 16" and that hit it for me, I would say for visual go as big as you are willing to port move lift  or house as long as your heart is in it on scale with the apertures you choose.

    Astronomy Cameras and Night Vision equipment can add many inches to a given aperture so if you have a dual purpose visual/eaa (electronic assisted astronomy) 8" telescope you will see far more than someone using a much larger aperture for visual only (especially with light pollution). For a user like this one a small/medium aperture telescope may completely satisfy the need for further aperture.

    Travel to a darksite will also help you see more with less, gas is cheap if a darksite is close by.

    Starting out folks often buy smaller more reasonable scopes that are usually quite forgiving with faster cool down times, easy setup and are quite workable and rewarding to use, going up in aperture it's good to keep one of those small scopes available as the larger apertures will have you reminded of how handy and useable they were/are.

    I dident give it the credit of a cross section drawing, like Gina's failed artist description best so far.

    My obsy consists of a table some chairs several scopes, cameras computers and other bits all on wheels now newly conserved in garage, completely all utilitarian of course but I do understand the need for an in ground pool and a couple Jaguars nearby...I have built in bar and senic over look close by too ?

    So I guess I'm not so innocent on the luxury side of things, intresting to know what others posting here have nearby their observatories...

    EEVA with DSLR?

    @SIDO Well, I'm very happy with my 224, just really tempted by the field I could get with a DSLR I have sitting at home. My choice today will be to get either a 294 or 183mono but I like to explore with what I have and experiment around, that's also part of the fun for me. 

     

    @Martin Meredith Uhm, yes an ASCOM driver for Canon is interesting and would make things simpler...  but eh my camera is a Nikon ?.

    I was reading around and found on the SharpCap manual that, in theory, everyone could just use the "virtual cameras/ virtual folder monitor camera" option to scan a folder and still be able to use darks and flats and keep using the main live stacking functions. https://docs.sharpcap.co.uk/3.2/#Virtual Cameras ... 

    Now, I can see few software like DigicamControl  http://digicamcontrol.com and probably Astrophotography tool https://ideiki.com/astro/ (and I'm sure others) to set up scripts or batches for running and saving multiple shoots from DSLR and that should work. 

     

    ....but now I see a problem why a DSRL may be not really ideal for fast EAA imaging...  clack clack, clack clack, clack clack, clack clack, clack clack,... unless I can take 5-10 seconds exposures (or more) directly from the live-view mode the sound of the shutter, running all the time, will probably drive me crazy and it may be not that good also for the life of the camera.?

    Or maybe, is it feasible? Only few shots to goto/plate solving and then run ~50 shoots for stacking? I need to try and see... 

     

     

    You would get a nice wide field with your 224 and a 50mm camera lens you likely have and with no clicking noises, at that f ratio you've got some fast light so the zwo model is not as critical.

    Could be another experiment for you ?

    The clicking thing would drive me somewhere too.

    A bar on the ground floor?. I'd never make it to the scope, because the stairs on all floors don't connect.

    This is ment to be some weird sort of "out of scale with itself" cut away drawing so intoxication might have more consequences in the final build than pictured, do take plenty of money I think the drinks may be pricey and so will the valae parking...

    Your asi224 using livestacking might be your best bet, using a Dslr really is an ergonomic stretch for live viewing and then the small screen too. 

    With your 224 you can livestack wide fields with a camera lens or all sky too, I am doing it with my imx385 and it's just fancy with my 16 or 17 inch laptop screens. I don't save anything and delete everything Sharpcap saves as for me this is just a sub for visual observations of the deep sky so when I roll my portable digital obsy back in the garage for covering nothing beyond the shorthand in my logs is undertaken.

    I am using the Zwo asi385mc as it is their recommended camera for eaa, they have advised me well the camera is very sensitive and has  an ampglow reduction circuit that really brings it under my Bortle class 4 skies.

    I am new to eeva myself...and glad to share what little I've learned so far.
