Splash screen at start up

I apologise for this truly awful request, but is there any way to reduce the length of time the splash screen displays at startup? On my machine (i7, 16Gb, GeForce GTX 1660 super) it takes approximately 7.5 secs to disappear. Appreciate there are probably things going on in the background, but if it...

Re: how to add rgb stars to HOO image

One way to achieve this (may not be the 'correct' way) is to set up a star mask on the foreground layer and set layer mode to 'Color of fg', then adjust 'Blend amount' to taste. Screenshot below of adding RGB stars to a bi-colour of the Eastern Veil (ignore the offsets, my RGB stars didn't line up w...

Re: Everything goes great until I try to balance color

I am no expert, but your data looks very nice, thank you for sharing. I had a very quick go using the compose module for the initial load and got the the result below. It would be handy to know the integration times of the four channels, to get a better result, but are the colours closer to what you...

Re: Using Heal to process stars and background independently

It still seems to work the same way here, Mike. You don't use the repair module, rather you create a star mask (that's where the exclude color comes in) then go into the Heal module and select New Darker than old. Exit, then clear the mask and save. After that go into the layer module, Undo bg and t...

Re: StarTools 1.8.506 public alpha/preview now out

That's a very interesting point, Jochen! Unfortunately none of my star atlas/ planetarium programs seem to go into that much detail, although Martin Meredith's Pretty Deep Maps shows the 'resolved' star as a double, it isn't shown in that orientation (sorry, this one is upside down compared to first...

Mike Having followed with interest, I can say you are not alone in this. I had a go at some previous data this morning and got a similar although not as pronounced effect: Selected star Selected star1.jpg Before SV PSF Decon: Selected star2.jpg After SVPSFD Selected star3.jpg A lighter pixel has bee...

Re: Combining RGB with Duoband for natural star colour

You might find this thread of interest:

viewtopic.php?f=4&t=2003&p=8798#p8798

About half way down Ivo mentions how to combine an RGB starfield with bi-colour data.

Is that what you are looking for?

Re: 1.8 closed alpha feedback

Had a few goes with 504 and it seems very stable. Nice! Just concentrating on the SV decon module and selecting stars in some M13 data I have from last month, and this is very minor point, but when trying to select 'green centred' stars, sometimes the blue boxes disappear from round previously selec...

Re: 1.8 closed alpha feedback

Don't know if this is of any importance, but when attempting to select stars in the GSVdecon module, I try and click on the central pixel (example below) and while this sometimes produces a blue box centred on the subject star, sometimes it doesn't. In the example below it seems pretty obvious where...
