  1. Hello, i am having so many difficulties as far as i remember to make some nice flats to match my images.For some reason it it impossible for me to find the secret spot in time and adu for my Flats. This is my equipment : Telescope: Redcat 51 Camera: Atik 383l+ mono (i know the shutter problem that's why i always aim for 3sec and above for taking my flats) Filter Wheel: Atik EFW2 (36mm) Filters: Astrodon Ha & Oiii 36mm 3nm FlatBox: Geoptic flat field generator 164mm (dimmable) Image aquire software: APT Tool v3.71 Software: Astro Pixel Processor This is what i get...i am uploading some images converted in jpeg for the site... Photo A is a MASTER FLAT Ha (Bin 1x1) created with 30 Darks, 50 FLats (3.7sec adu 22000), 50 Dark Flats, 100 Bias Photo B is a MASTER FLAT Oiii (Bin 2x2) created with 30 Darks, 50 FLats (5sec adu 46000), 50 Dark FLats, 100 Bias Photo C is an example result of stacking my fits of Helix Nebula at Bin 2x2 , with the above calibration master frames (this is the Oiii in this case) Are my calibration frames Over correcting ? if yes what can i do ? Is the Optical path problematic ? as i can see at photo A ? what can i do , what to check ? I have checked also the filter wheel position related to filter change , but it comes centered...i couldn't see a fault on it. i Believe i have a problem also finding the correct ADU value....i made any experiments by changing the adu value and i have tried at 22000, 32000, 47000 by using the CCD Flats Aid.......but nothing all come out the same. I hope someone can help cause i am loosing my mind and my fits

    From the album: Galaxies

    M31 - Andromeda Galaxy L= 52 x 600s R= 15 x 600s G= 15 x 600s B= 15 x 600s Equinox 80 NEQ6 Pro Atik 383L+ Taken on the nights of 11th,14th,15th,17th,18th and 19th August 2012 Captured with Artemis. PHD Guiding Stacked, aligned with Maxim DL Flats, Bias and Darks applied. Processed with Pixinsight, MaximDL, Images Plus and Photoshop CS3.
  3. After nearly 4 years of imaging I have finally got a CCD. Got an Atik 383L off a member and intend to do some narrow band, starting with Ha and will see how it goes. Here it is attached to my Canon 70-200mm L. Could'nt get out to obsy tonight so gave it a quick test indoors. Just aimed it at some cards on a wall and took a 10sec exposure thorough an Ha filter.
