    Tak 102 SX694 62 x 300secs test shot to compare the finder guider and the OAG with the tak, they came out pretty good so i combined the lot. The outer halo is starting to show so this may become a project.

    Celestron C8 Hyperstar - First light report

    Hi everyone Here's my first light images and initial thoughts using my Celestron C8 Hyperstar. For the purposes of the report, I am using a ZWO ASI 178 MC Cool camera, Baader Neodymium Moon and Skyglow Filter threaded onto the Hyperstar unit. All images captured were 2 min exposures using APT and Unity Gain setting on the ASCOM driver. Camera was cooled to 0 degrees C. Setup I have the luxury of time being on holiday from work so spent Monday morning setting up the rig and testing the camera through the Hyperstar on some passing clouds etc. We did get some clear breaks in the clouds so I took the opportunity to shoot some flat frames against a neutral sky? Observation #1 - you can't use the t-shirt method for flats because of the camera position so, following the guidance on Starizona's website, shoot these against a neutral sky. Balancing the scope with the Hyperstar on it was surprisingly easy. There is enough weight in the rear cell of the SCT to counteract the camera and Hyperstar on the front. I left my focal reducer and diagonal on for good measure but these are completely redundant. Once night fell I completed the setup with a polar alignment and star alignment using Sharpcap for alignment and initial focus and the finderscope on the OTA for visual reference. Job done. Pick a target I wanted to give this a good test without a daunting challenge of the faintenst thing in the sky so I plumped for NGC 7000 - Cygnus Wall. After a bit of faff with APT I managed to get the framing I wanted. Observation #2 - the live function in APT and the Hyperstar really do help because you can get some good snapshot images visible straightaway. Observation #3 - you need the touch of an angel on the primary focuser to get this right. It's so critical at f2! Guess I'll be asking Santa for a feathertouch focuser!! Once in position I set PHD up and off we went. 60x2 min subs please. First image OK - so I'm a kid with a new toy. The first few subs that came back looked really good so I grabbed 8mins worth and did a mini stack in DSS, no calibration frames - just lights. A quick process in PS CC and here's the first image out of the can. OK, it's a bit ropey (satellite trails, gradients, ampglow, noise - you name it) but it looked good for 8 mins worth. I carried on and finished the 2 hrs and then turned the scope onto M33 - Triangulum Galaxy. By now it was 1:45am so I figured I'd grab 30 mins, again to test the speed of this thing. 30 mins later my eyelids were drooping so I warmed the camera up, pulled the roof over and went to bed. Final results After some well-earned kip I set about shooting some darks and started to process the 2 images in Pixinsight. Here's the results. 2hrs integration on NGC7000 - Cygnus Wall 30 mins total integration on M33 - The Triangulum Galaxy. Quite chuffed with this one - took me more time in processing to extract the detail but it was worth it. Not bad for 30 mins - this would normally take 3-4 hrs with my DSLR Final thoughts - I guess it's like everything in this hobby. You need time to practice and every change of kit, no matter how small brings it's own challenges. I'd welcome some feedback but for now I'm happy where this is taking me Cheers Chris

    Added the 9 plus hours of OIII I got last night to this. Had a heck of a job lining it all up as I must have knocked the camera and had quite a bit of rotation between the HA and the OIII. Came out a tad on the bright side on this monitor. Totals so far. 5 and a bit hours of HA 9 and a bit hours of OIII Just the SII to go. Click on the image a couple of times to get to full res.

    Cocoon Nebula

    Perfect clear night and 4 hours+ of imaging, but I'm not happy with it!! Although it's mono (& Ha) it seems to lack definition and contrast. I spent quite a bit of time getting the focus as spot on as I could but stars still look a bit bloaty! Then having to refocus for the adding of the Ha filter was a pain but I did it properly using Deneb to focus. Maybe this adding of the reducer/flattener will help, we shall see!! Anyway results are these, Cocoon in mono, Cocoon in Ha and IC63 in Ha. All 300 sec exposures Mono x 6 Ha x 12 and IC63 Ha x 3 + Bias frames. No Darks

    Found this on my travels thought it made interesting reading showing how our great great great grandparents heard about monthly events in the night sky. From the Daily Graphic Wednesday January 7th 1903

    That needs more data and colour, it's just begging to be added to. Great image Steve.

    Baader VariLock spacer

    My Baader VariLock spacer arrived today, 29 - 46 mm adjustable and lockable spacer. I can now use my reducer/flattener with my SVX-H9 CCD having got exactly a 55mm spacing between the reducer and the CCD sensor.

    Hello there!

    Hey everyone. Asked on Facebook about meets and the sort and was sent here. I'm an absolute beginner at all this so I really am sorry if I ask stupid questions. O used to have a telescope when I was a lot younger but nothing too serious. Argos special I think. It's my birthday soon, and I was thinking of getting a more serious scope. I have no idea what I want it to do let alone what I want to do with it. Any advice is gladly received. My budget is Β£150-200 mark. I was thinking this budget (whilst it may seem low, is actually quite a big chunk) I'll have to go second hand. Anyway. Hopefully see some of you at the next meet. Thanks.

    Very nice. NAN looks great for just 8 minutes. Your M33 really looks superb and has brought out son much detailed structure. πŸ‘

    The North American Nebula

    It's been a while but finally managed to get a clear sky I could use. This is my first try at this. I was only able to image part of it but now sure which part. 14 x 300sec @ ISO800 with Darks, Flats and Bias frames Processed in Star Tools and finished in CS2 [img

    I’ve gone hyper(star)πŸ”­πŸ˜‰

    I really think you have to give Celestron the thumbs up here. From what i can see they are one of the few scope manufactures, if not the only ones developing systems like the Hyperstar, and introducing the RASA imaging scopes for the masses. They are bringing out an 8" RASA very soon to go with the 11" which looks very interesting as they have completely redesigned the focuser. Imaging at F2 with an 8" aperture sounds very compelling, especially with a OSC type camera. Really looking forward to seeing your results Chris. Good luck with the new set up.

    well.....it fits at least.... I now have a x28 faster exposure of my shed roof and a minor heart attack removing the secondary mirror. What I now have is a 390mm focal length scope operating at f1.9 - again, according to the blurb
