VNC works whether you have a connection to the internet or not, as it's point to point between the two devices (as long as they are on the same network, which can be isolated). If you're using your phone as a mobile wifi hotspot, then your laptop is connecting to the internet through your phones data connection. Yes, you can do teamviewer, but you're no better off than using the normal house network.

Windows 10 should be able to display the raw image (it can for my 60d Raws), but you could use the canon software, that will do it, and you should be able to see them all as thumbnails

DSS is not processing dark or flat frames
jgs001 replied to sshenke's topic in Getting Started With Imaging
That's exactly it almcl... The groups allow for stacking sets from different nights with appropriate calibration frames for each night. However, the first group (main) is used for all other groups, so if you have something in there that is for one specific night, you should remove it and put those into their own group. if you have something like a master bias frame (for example) that doesn't change, you could put that in the main group, then it will be applied to all other groups. If not, add one image file to main, to open group 1, then remove it from main. -

They look fantastic -
Rotating Stars
jgs001 replied to robindurant's topic in Imaging - Image Processing, Help and Techniques
Robin, you can push to about 2 minutes, when the target is low in the east or west, but the higher it is, and the further North/South, the shorter the subs get to avoid the rotation. I don't recall the numbers now, but I bounced on this quite hard in my early days using a Nexstar SLT mount. -
Good Ebay Score - Celestron C6 Newtonian

looks like a fantastic bargain, excellent -
Very well done Michael, Congratulations and well deserved.

If I may, I'd like to thoroughly recommend this book. I don't read biographies normally... just not my thing. This one is, IMHO, well thought out, well written and very engaging. My eldest brought it for my birthday earlier in the year, and I really enjoyed it. I don't want to say too much as it may spoil things, but it's about the year Scott Kelly was aboard the ISS and his journey to get there.

Welcome back Kev

Nasa has found a number of planets in the TOI-270 system that, based on the reporting I read, seem very interesting, and quite close. https://www.independent.co.uk/life-style/gadgets-and-tech/news/nasa-planet-new-tess-satellite-star-solar-system-astronomy-discovery-a9025621.html

If anyone fancies a new ringtone or notification tone.. NASA has made a number of 'soundbites' available in MP3 and MP4r formats https://www.nasa.gov/connect/sounds/index.html

Picked mine up yesterday. Didn't see the Saturn 5 and the rod poyle book... May have to place another order. Thanks again Paul

Alan, Yep, done it myself. Use the batches in the same way as exposure lengths.

You get used to it Paul 😎. Mine is available for pickup now, but will have to await the weekend.

Steve, you will need to stack the AVI's into a single image before using iMerge or MS ICE to complete the picture. I used to use registax, but changed to AVIStacks as it was so much faster and easier to use.

I've used various services, and most of the time they are pretty good. If you can though, it's worthwhile getting the printer preview proof settings for your editing application, and then you can 'view' the image on screen as it's expected to print. I found a couple showed as being much darker than expected.

Thanks, ordered this one... and the Apollo 11 one... same price, and a nice matching set

Good (cheap) 50 to 100mm Canon lens
jgs001 replied to Mr niall's topic in Getting Started With Imaging
The nifty fifty is the cheap Canon EF 50 mm prime lens. It's cheap, lightweight, and yet, has amazingly good optics with a fast f/1.8. Brand new is £99. https://www.camerapricebuster.co.uk/Canon/Canon-EF-lenses/Canon-EF-50mm-f1.8-STM-Lens -
Good (cheap) 50 to 100mm Canon lens
jgs001 replied to Mr niall's topic in Getting Started With Imaging
Enjoy the Nifty, it's a craking little lens, I found f/4 was needed to get a reasonably good result. I'd suggest looking at a macro lens (make sure it's a true macro, and not a macro labelled zoom) for Astro, given the price of the Samyang. Macro lenses are designed to be optically flat and, thus can be used wide open without issue... I have a used Sigma 150, and it's a belter. The canon 100mm macro can be had for £120 for example -
I have an older IDAS (not tested under the new lighting we have yet) and use it with unmodded 450d. I cannot give you any idea of the quality of my skies (although, I understand they are pretty good).

If you have at least 12 subs, statistical stacking should remove them, it worked great for airplane trails for me.. however, that's still a huge number of satellites, and without some way to 'bring down' the dead ones is going to make the orbits very cluttered.

Nifty fifty Cygnus widefield HaRGB

That looks excellent... I may have to try my macro lens out... see what that can grab. -
Samyang 14mm possible lens problems need some advice please
jgs001 replied to Danjc's topic in Getting Started With Imaging
I'm gonna guess that the camera sensor was not totally parallel to the wall, as you have a little more barrel distortion on the right hand corners than the left. The focus, to my eye, does look a little softer to the right of the image, that might be due to the distortion effects, but... For focussing, if you have an android device (tablets work really well) with a USB OTG port... connect your camera and use "DSLR controller". This allows you to use the liveview and really zoom in on a much larger screen. You can't use all it's features with the Samyang, as it's fully manual focus, but the app will allow you to remotely control the focus of the lens directly at varying speeds, and works really well. You may need to look into back button focusing to decouple the focus activation from the shutter button if you want to give this a go. -

jgs001 replied to Danjc's topic in Getting Started With Imaging
Try mounting the camera setup on a tripod, and take a picture of a wall (boring I know ;)). It may help to highlight any issues... it does seem, from that shot that the focus on the right of the image may be a little better than the left. -
Thanks all... If I'm honest... I'm still struggling with navigating the site at the moment... only just found the quick way to find your own threads
