    Its been a while.....

    Sorry to be ignorant but what are we looking at? I've just started using a Samyang 135 with an Atik 428mono and I've been delighted so far with the results at f2. I'm waiting for a clear moonless night to give it a go with the 414osc. Adrian

    Mini-Pc - Weatherproofing

    Hi Jason, Yep, purely reliability. I have some sort of WiFi gremlin here which causes me endless problems. I've tried using WiFi but just find that invariably it lets me down and I end up with a curtailed imaging session - especially if I have gone to bed to let it get on with it unattended. Also with my very long 30m cable I can move the whole thing well away from the house and see a little bit more of the western sky. Good luck! Adrian

    NGC7000 + IC5070 - is adding SII worth it?

    You were correct Wim - try as I may I can't tease out any more detail so I've gone for colour - a purely subjective result. Time to move on to another target

    NGC7000 + IC5070 - is adding SII worth it?

    Hi Wim, Thanks for the advice. I've decided to give it a go and see what happens. Colour variation is good. The first 600s exposures are looking promising and if it stays clear I should manage to collect 12 of them tonight. I really like my new Samyang 135mm; it is great for capturing these larger DSO targets. I've tried mosaics but without a camera rotator I've found it all very frustrating. Roll on the longer, darker and hopefully clear nights! Adrian
  5. Hi Everyone This is my attempt at a combined NGC7000 and IC5070 although I have to say I'm not sure which way up it should be. The image comprised 10x300s + 10x600s Ha and 10x600s OIII. Is it worth adding SII? Will it reveal more detail? Taken with my Atik428 mono + Samyang 135mm at f2.2. Stacked in DSS and combined and processed in PI with a few finishing touches applied in PS. Critical observations would be welcomed please to help me improve the final image. Thank you for looking. Adrian

    Mini-Pc - Weatherproofing

    Hi Jason, Not really. I like the idea of minimising the cables but I also want the flexibility to access the NUC. At the end of an imaging session I bundle the cables into the plastic box and bring it in. If I need to access the NUC post imaging all I need to do is plug the box into the mains, hook up a network cable and access it from the laptop. It is also easy for me to remove the NUC from the box and use it stand-alone for other stuff. I don't have a pier - I use the tripod that came with the NEQ6 which allows me the flexibility to put the mount anywhere in the garden. This is the setup in action - imaging NGC7000 - a quick shot as the image was downloading! You can see the white network cable and the blue mains extension running back to the house. I know it's not elegant but it works for me and is so, so much better than when I ran umpteen cables through a hole in the wall and was restricted to being no more than 5 metres from the house. Good luck! Adrian

    Mini-Pc - Weatherproofing

    Hi, I did exactly what you are proposing just a few months back after 18 months of trailing far too many cables through a custom made, weather proofed hole in the wall into our extension. I now house everything in a clip-lid box as per the attached photographs - hope you don't mind me photo-bombing your thread. I run a single network cable back into the extension; the mains lead is plugged into an external socket on the back of the house via an extension cable. I use a second-hand, refurbished laptop which came with Win10Pro installed to connect to the Intel NUC (running Win10Home) via Remote Desktop; it works a treat especially if I connect the laptop to the network and do not rely on wireless. I use ASCOM, SGPro, PHD2, CdC, HitecFocus and Atik Artemis software. I usually sit the plastic box on an old wooden stool - it makes it harder for slugs to find their way into the box! When it is windy I put a brick on the box lid. I resisted drilling holes or making slots in the plastic box as it tends to weaken the box. I now find my setup and strip down time is substantially less. I also have a second 30m network cable so I can position the mount and OTA pretty well anywhere in the garden to best suit the imaging target. Hope this helps. Adrian P.S. The big grey unit in the box is an old 20 amp amateur radio 13.8V psu - it's 35 years old, weighs a ton but is absolutely rock solid at powering the camera, etc.
  9. Hi Everyone, With barely two hours of darkness and a 50%+ moon I was probably wasting my time, but I am keen to see what my Samyang 135mm + Atik 428mono can do. This is 9x600s Ha + 9x600s OIII over two consecutive nights, preprocessed and combined in PI with a bit of localised enhancement in PS. It might not win any prizes but I was pleased I could see something of the Veil (Eastern & Western) with so little imaging time. Roll on the longer, darker nights so I can add more data before this part of the Milky Way disappears behind the house! Thank you for looking. Adrian
  10. Hi. I use my ED80 with a Canon 70D and with either an Atik 414osc or 428mono. I've used it with and without the flattener and I can see no difference at all with the Atiks - and it gives me a slight improvement in the size of the target for galaxies. I think there is a marginal benefit with the Canon 70D. For larger targets (nebula) I use it whatever the camera. Not a waste of money but not an absolute necessity as far as I am concerned. Maybe so with a much bigger sensor. HTH

    Workflow.

    I am no expert but this is what I do: Take the mount, scope and box containing the power supply, NUC, focus unit and dew heaters outside. Connect everything up making sure I always connect mount/camera/focusser/filter wheel to the same usb port - everytime. Connect the network cable to the hub inside the study - via a convenient hole in the wall. Switch on the mains power and power up the mount and NUC. Polar align using the polarscope and my iPhone app - and right eyeball. Come inside and connect using Remote Desktop to the NUC from my laptop. Start EQMOD and connect to the mount and 'unpark' Start CdC and connect to the scope/mount; make sure I am using Equatorial coordinates and J2000. Start Artemis (Atik software) and track to nearby, easily identifiable, star; nudge to bring star to the centre and fix with CdC. Start focussing software and carry out my initial focus by aiming to achieve the lowest FWHM figure I can get. Track to another easily identifiable star on my way to my initial target; nudge again to bring star to the centre of the image and fix with CdC Repeat previous step once more making sure my last alignment star is near my target. Start PHD2, connect everything, pick a star and start the calibration process; allow the tracking to settle - how well things settle seems to be directly proprtional to the FWHM figure I get when focussing the main scope - the lower the FWHM the better it tracks - at least that is my perception. Stop the guiding. Finally move to my target location, check the focus once more in Artemis - refocus if necessary. Close Artemis and start SGPro, set my sequence up, plate solve if I'm feeling lucky otherwise I just take a longish 2x2 images and hope there is something I can centre on. Once I am happy I am on target I restart the guiding, let it settle, start the sequence and go and make a coffee. If my luck is in the clouds stay away, Windows doesn't update, the neighbour doesn't put his outside light on and we don't get a momentary power interruption. I've tried focussing with SGPro but it never seems to go well and I just waste imaging time so I use Artemis; this is especially so if I am doing NB and have the Ha filter in the holder. It's great when it works and seriously bad for your blood pressure when it doesn't. HTH's

    Bubble level

    I can recommend one of these - nice and big and easy to see - and a near perfect fit in the circular recess of a SW NEQ6-Pro tripod! Available from Amazon! https://www.amazon.co.uk/Acrylic-Spirit-Bubble-Diameter-Degrees/dp/B00KP8YNJG/ref=sr_1_1?ie=UTF8&qid=1527769009&sr=8-1&keywords=acrylic+spirit+level+bubble
  13. Amazing image. Congratulations on a great capture and some top-notch processing. Adrian
  14. I think pixelation will be a problem if you go too far. This is an image I posted last year using the osc. Compared with many this is a pretty modest end result but it gives you an idea of what I acheived. I used a R/F but to be honest I have also used the ED80 without a R/F and with a sensor the size of the 414 or 428 I cannot discern any issues. HTH
  15. Hi. I have an Atik 414osc and I love the convenience it affords and the quality of the image it provides with my ED80DS-Pro. There are times I just want to get an image without a lot of extra stuff, e.g. filters and stuff. The Atik is relaible and well made and cools easily and consistently to -10 or -15 and works a treat with SGPro. I also have an Atik 428ex mono and I am very pleased with the NB and LRGB results I have obtained. I would imagine a 414 mono would provide equally pleasing results. I have to say my interest is very much moving from galaxies to nebula and I've just married the 428 with a Samyang 135mm lens. The CCD calculations tell you this results in significant undersampling but I am more than delighted with my early results. So much choice and so many things to consider all the time. Good luck
