PH-R

M33 captured over 4 nights, 16hrs of data using 300sec subs, darks from library, mixed flats for an average and bias frames. Camera: Canon 600D. Everything put into Deep Sky Stacker and the resulting image processed in PS. I used a video made by Scott Rosen on processing to help me process and I learnt some really powerful techniques to use in PS. I think this is my best processed image to date, so I feel happy I have made some progress. Looking forward to reprocessing my old data armed with the new knowledge 🙂.

I agree, really gives a sense of the vastness of space..

This was my second target I started collecting data on back in April this year. After my first attempt on M101 using 180sec subs I went for 300secs, which I think is much better for my set up. 100Ed, Canon 600d, 300sec subs 98% 13hrs 35mins. I will look to add another 7hrs when I can. Calibration frames used. Crop + original:

Really good way of presenting your work. great images.

Very nice and sharp, almost like you are shooting through clouds on earth!

Excellent!

Upgraded my old EQ6 (non GOTO) to EQ6-R and Canon D10 to 600D and now I can do proper long exposure pictures 🙂 My first image is M101 11hrs 30mins captured between the 22 and 25th April 2020. Obviously a lot to learn on the processing side. However, I am really chuffed with this result, especially considering I am using my good old gold Skywatcher 100ED (0.85 reducer). Watching APT do an auto meridian flip was a sight to behold and very satisfying. What I think I learnt, I should use much longer exposure times and higher ISO(gain) on faint targets like these. I could hardly see M101 without stretching sub at 180 secs ISO 800. I imaged M92 on my last night as a test at ISO 1600 and subs of 300 secs and the back ground looks great. Fingers crossed for clearer weather tonight as I am hoping to start getting M51 data later on. ( we all live in hope 🙂 ) Full size plus crop attached.

Hi all, I need to replace my shielded USB cable as it is not long enough. Can anyone recommend where to buy a good quality one. Also I noticed a HDMI port mini B I think on the camera. Could I use that instead and what are the pros and cons between the two standards? Thank you.

Happy to get something last night after all this rain! Now I just need Mars, Neptune, Uranus and Pluto to complete my set.

I was very lucky between 12:30 and 13:00 then the showers started.

I had a look in PS and with my limited knowledge I would say no. The red channel is 0-5% on the histogram, blue about 30% and green 40%. My flats show all channels at about 50%. Hope this helps.

Thanks for the replies. I have just been out and taken some flats and everything is looking good (1.51 exp. peak in centre of histogram). I discovered my error. When I was putting the tablet on top of the telescope even though it looked flush, light was still getting in. I rectified this with blackout over the top of everything. I set my tablet to the lowest dimness and needed one sheet of white paper between tablet and dew shield.
