Let's see your 1st DSOs

Well I've been in to visual astronomy for about a year with a little 100mm f5 refractor and recently acquired an 8" f10 Meade LX-10 from Dad-garage-bay.com it's the first time I've had a clock driven scope so i decided to give imaging a go As the scope has no autoguider input i had to get crafty with with a box of tricks to convert the ST-4 output from my borrowed autoguider to a hand controller type input that the LX-10 accepts and it seems to work fairly well... my polar alignment still sucks but i can guide some of that out at the expense of image rotation...

So on October the third i attached a borrowed Canon 500D to the 4 incher and after much fidlling, cursing, crying and then processing in IRIS i came out with my first Deep sky images!

M31 - 24 frames at 120sec iso 400 100mm@f5

M42 - 18 frames at 60sec iso 400 100mm@f5

M45 - 12 frames at 90sec iso 400 100mm@f5

M57 - 15 frames at 150sec iso 400 200mm@f10

This is my first DSO image of the Orion nebula taken very recently with a Antares 80mm f/6 refracter on an ra driven basic eq5 mount, 4x10 seconds and 1x15 second exposure at ISO 400 with a Cannon D1100 SLR, stacked in Deep Sky Stacker and sharpened in Photo Pro.

Well here goes, Some of my first attempts at deep sky imaging, I,m fairly new to this astro imaging of which (I,m Hooked).

M31,M13 and M42.

Skywatcher 80ed on a eq6 using a nikon d90, unguided. Im just learning to use guider now, so i shall send more images.

HELP! How do i get my images on here.

Hmmm,

Here's my naff 1st attempt at a DSO......M13 (noticed this is quite a favourite with newbie imagers....wonder why?) This is a SINGLE 30 sec sub, Starlight MX7C using AA3 for capture and process......the rest are far too blurred (naff mount)

These are my efforts with a Skywatcher 150PDS on an NEQ3-2 mount and a Canon EOS 60D - unmodified.

I would like to get into guiding but I'm not sure how to interface the RS232 connector to my laptop.

Hi, here are my first 3 attemts:

M82, EOS 5d mkII on C11 edge HD 8 minutes ISO 1600, would need more time to get it better.

M31, QHY8L on SW Evostar 80ED pro, 120 minutes

M33, QHY8L on SW Evostar 80ED pro, 40 minutes, need more time.

All guided with SW synguider.

My first DSO is actually my best so far by a long way. Taken of the Orion Nebula about a year ago.

Telescope - Stellarvue SV105

Camera - Self modded Canon 350D

Exposure - ~85 minutes total (12 x 5 min, 12 x 2 min and 10 x 10 sec)

Mount - Skywatcher EQ6 (with EQMOD)

Guider - Orion starshoot (with PHD)

Guide scope - Stellarvue SV80ED

Subs are the individual exposures which vary in duration depending both on the target being imaged and the capabilities of the equipment being used. Several subs are typically stacked together to produce an overall better signal to noise ratio i.e. 10 exposures of 5 mins each = 10 x 5 min subs. When stacked together you have a total of 50 mins worth of exposure. If you left the shutter open on say a DSLR for 50 mins in one go, the amount of noise (heat interference on the camera's chip) would ruin the image, that and it would take a really good set-up to be able to track for 50 mins with no star trailing. Taking shorter exposures and stacking them is a technique used to obtain more data (signal) but in shorter time frames to help reduce (noise).

Of course, that's a very simplistic version :-)

Hi guys, Hopefully these have attached ok,

The first pic of m42 is my second attempt at a DSO and was under nearly a full moon, and was my first attempt at stacking (my very first picture is on another computer but looks very similar)

it's 15s x3, 8s x2 and 4s x2 at iso 1600

and then my 3rd attempt form wednesday evening (the moon was much lower for this one) i think that's 30s x6 and a couple of shorter exposures at iso 1600

and also my first attempts at m33 and m31, both 30s x 3 at iso1600

I was very happy :icon_salut: considering the light pollution in my area, the fact that the moon was bright, and the small number of subs

Still waiting on my coma corrector to arrive.

It's interesting how some peoples first attempts of DSO imaging were guided with modded camera.... :) they're some very nice shots
