This is the new Astro camera QHY268M ASP-C size sensor ...... Unlike a DSLR where you pick up the camera and go, a deep space camera requires a lot more set up. As this is the first shot I thought for those interested just what is required. At the very start you have to make sure that your rings match the back focus of the particular camera. in this case it is 55 mm from camera sensor to the corrector that picks up the image from the mirrors. So all the bits between filter wheel and Off Axis Guider all have to fit in that 55 mm spacing ... Remember this is a cooled camera I try and always use -10 c but on hot night i have also to use 0c a second set of darks. DARKS : These are shot that are taken at the times you will be using in you photography Eg 300 sec . So you have to take your exposure time you would be using BUT with a cap on the camera so there is no image but what there is is an image of all the noise that the camera creates in those times. You create a library of about 40 shot of each. This is a 300 sec dark master I did 7 different exposure times 7 x 40 shots = 280 shot from 10min to 30 sec... quite a few hours shooting. FLATS : These are taken at about 1/4 exposure above the Dark point in between to the middle point. The good part is the program is able to work it out. Each filter has to have the same 40 shots. This is used to show up any imperfections in the optical train such as Vignetting, dust, scratches. This is a master flat made from stacking the 40 shots with also how many bias files you took. This is for the red filter you can just make out the slight vignetting in the corners center is brighter..... 7 filters x 40 shots = 280 BIAS : Bias frames are taken with the camera lens fully capped, at the shortest possible exposure time, to ensure only the sensor noise is recorded. These are use with the flats to create the master flat. I did 100 as they where timed at 0 sec... While Darks and Bias files show up noise they are both very different patterns. OFFSETS : The all important focus point the clearest filter is Luminance so this is used to get focus . Offsets are made by running through all the filters to get perfect focus 3 times each about 60 min cycle. Then in the end it calculates the difference of each focus point for the filter to Lum and applied as the offset. To make it easier to understand if lum is your base or 0 if Red is +1 focus point then filter focuses on lum 1600 but when its Red filter it adds +1 to the focus point 1600 +1 as worked out by doing the offset run for each filter. This is the new part to me as I am only just starting with filters. NOW YOU CAN TAKE A PHOTO and why most photographers will shy away from this type of photography. Is it worth it to me yes ..................... enjoy the shots. When the shots of the nebula are taken checked they are all stacked with the Darks, Flats and Bias to remove all the optical faults and noise to get the clean shot that you have seen before and above. You can not start with out all this info and shots just to get the one Perfect photo. All part of the learning curve of the last 5 years. Enjoy the result of about 1 hours editing and all the shots that make up this single image, all the very best to Ai you never can better the original or stand as proud of your work. This is un ashamedly the result of a lot of work. Do look at this as big as you can, look at the detail, not one bit of noise straight out of camera enjoy the shot.

You have seen part of this before but as I am waiting for a target to rise In the milky way that I found when I did the milky way panorama. I do not have a name for the nebula but know where it is on the milky way its one I have never see in any photo so it going to be a new look at some thing I have never seen close. A tiny red dot in the middle of the huge panorama below. The Running Chicken can be see as the second largest red nebula on the far right of the huge panorama. So what became just the" body" top left I went clockwise taking the whole of the Running Chicken Nebula as an extra 3 shot to get the whole of the Nebula. I still can NOT see it even though I am enjoying this years Shiraz I still cant see no chicken. none the less enjoy the fruits or a lot of night to get the total in all its detail. Last was a single shot ED80 and APSC ZWO as a single shot. this is ED80 and 1" Sensor on the QHY 183 gives you an idea on the effect a sensor has on a photo but this is 4 shot to get the same amount of area as the single shot on the ZWOASI071 MC pro. QHY 183C -10c 55 shots 10 min over 9 night some in moonlight. .

Lower's nebula (Sh2-261) is found on the outermost edge of our Milkyway between the Orion and Perseus arm. The target is very close to the Dreyer's Nebula that you see right next door. This was cut short by the moon rising to this target but the three nights data yield is very good target. I want to do two targets that are in the same area so I have to wait for at least 6 days to get the targets free of direct moon light. This looks to me all the look of a brain. QHY 183C -10c 34 shots each night 10 min each over Three nights.
