For  a test shot i would be be chuffed !!

My next major purchase must be a SCT though it will be an 8 or 9.25 , my Heq5 pro couldnt take a C11

Lovely image

If this is the sort of image you get with a C8 then look out credit card

will give it a try

Cheers

I set the binning in APT in the image plan settings but im not sure how i would do this otherwise.

I use DSS and Gimp though i am trying Photoshop now

The ST102 focuser itself had a mechanical wobble when i took it off the mount so i have retired it and gone back to the Skywatcher 

ED 72 that should improve things hopefully. I used the 102 due to its aperture over the ED72 . 

I have been back and forth over binning with the 183 and used 2x2 for a while but i decided to go for 53 gain instead of 111

and to use 1x1 binning and 60sec exposure to see if that improved detail and dynamic range as i felt that at 2mins ,111 gain and 

2x2 binning i was oversaturating the chip and losing detail. i recently imaged the iris nebula with these setting as was dissapointed with the results hence the change in settings.

Thanks for your input .

The weather is about to change for the worse again !

Thank you for your advice and  comments

Clear Skies !

Thanks for the advice 

I took flats this morning and restacked. I took flats using a white box and APT ccd flat aids

I use DSS to stack my images 

I am thinking about buying a ZWO 533MC pro to replace the 183 or compliment it 

Here we go

Cheers

Took this last night , sky was a bit hazy i think

Any comments appreciated .... Processing not my forte unfortunately  i dont have the patience

No flats were used and as usual the filter wheel shadow is there

ASI 183MM Pro 60x60s Lum, 30x60s RGB, SW ST102 Guided

NGC 898 is in the centre by the way

Cheers

My next target as well thanks for posting

What gain did u set for the 183 ? i used 2min exposures on M76 at gain 111 and felt the inner details were blown out . it was luminance only as well

thanks

Wow something to aim for ! Well done

i will have to invest in a complete HST set of filters. M31 is also on my list to do well with my modified 450D though i may try a 

mosaic image  with my 183..... a zwo dual narrowband filter looks interesting

How do you find imaging with a newt ? i have looked at getting a 150pds 

It was set to -10C using the latest APT which has improved support for ZWO cameras now. To be honest it was so cold i could have done without it !!

I agree about the feeling but i rush things now due to the weather.  i got runtime errors using CDC and eqmod and nearly gave up

if you would kindly post your image as well

Cheers Mike

My first image of M76 A bit rushed as clear nights are a rarity now

30x120s Bin 2 Luminance ,SW 102 , ZWO 183MM Pro , OVL field flattener ,guided , processed in Gimp

Took some Ha as well but poor results for some reason

Seems an Oiii filter may have brought out some more detail

i know its not great but just chuffed to have imaged it

My first M82 with my new HEQ5 Pro RBM after many frustrating attempts and threats to sell the lot

Finally managed to polar align with polemaster 

Telescope is Startravel 120 with OVL field flattener and Astronomiser modded EOS 450d

 with CLS CCD filter

30 x 1 minute subs DST cropped  

I have tried to removed artefacts
