josh (Luke) · #1 15-05-2006, 02:03 PM

Hey folks
At last, scope is fixed and i had some time with the dsi. Full moon and some haze, just messing around with settings at the moment.
Heres some i grabbed {colours are crap and focus is off but im still pretty happy to have some images}
All through lx90 at 3.3
Anyone feel free to have a go at fixing them as my photoshop is a wee bit rusty
ill try to attach now {i alway stuff this up}

Great start, josh! Can't wait to see the results of your second night out!

EzyStyles (Eric) · #4 15-05-2006, 02:54 PM

very nice for first spot josh! keep it up

how many pics did you stack and exposure time btw?

Doug · #5 15-05-2006, 03:32 PM

G'day Josh, they are pretty good first light images.
I couldn't do much with the Omega images because they are rather under sampled.
This is not your fault, it is to do with the pixel size of the DSI and the focal ratio of your optics. Also, because the DSI chip is so small relative to a DSLR for example, when a DSI image is enlarged to look as big as other images, the pixels are more noticable.
On brighter stars this is not such a problem because the stellar image is spread out over more sensor realestate that the very fant hence fine stellar images in a glob.
The Best that could conveniently done with your Glob images would be to shift the colour and maybe a bit of a curves adj.
Try imaging Omega at f10, but tracking will become more finicky. On the plus side, at f10 focus will not be as critical as is at f3.3.
here is a cheap and nasty job on A-crux, cropped and various things..

keep up the good work
best,
Doug

Congrats on your first attempts with the DSI

Look forward to seeing more.

Hey Ezy
I think it was about 10 stacked @ 8 seconds. Im not sure how to set gain and offset, i guess i need more time to play around.
Thanks for that Doug. I couldnt see those ather stars in my original acrux.
I wass all work up for another night but she be very cloudy and wet for 2 days now.
This photography stuff will be very addictive me thinks.

these are great.

i have a toucam and do planetary, so have no clues with the DSI and anything else on that matter.

EXCEPT, the old ezy is a great one to help guide you. His rise to fame and hollywood "star" dom, "nebula"dom was huge!!!

Top stuff!

EzyStyles (Eric) · #9 16-05-2006, 07:09 PM

thats excellent for only 8 second 10 pics stacked. the more you stack and abit longer exposure (probably around 60 second 84 second mark) the greater the image will become. normally you leave the gain/offset set to default which is 99-100 for gain and 48-50 for offset. Only adjust these for planetary work with the DSI. keep it up josh.

all embarassed... thanks dave.

Actually there are about twice as many stars in that image as I showed, but stretching them out really cooks A-Centauri-a so, better not to do it.
Best,
Doug

famous last words on a few fronts

Striker has a book out on how to buy equipment without your spouse finding out, it also has an emergency section on what to do is she does find out. There are also counselling sessions in a town near you.

For starters, leave the settings alone, but don't forget, no-one is an expert. This current Jupiters season has turned many capture settings on their heads because people have tried something different.

It has been an exhilarating ride keeping up with developments!
