  1. Cheers Frances - I have read your threads on the 294! A main reason I went for the 294 was that at the time I was imaging unguided at 60s subs - the 294 seemed to perform well at this, with tracking I wouldn't push much past 180. I am used to stacking hundreds of subs (I recently discovered the Blink function in PI - AMAZING). My dark library is ok, my flats and dark flats are useless, I suspect when I get good flats a re-run of the data will come out nicer. We have poor weather this week so I wanted to spend time on calibration data, I just need the kids to give me a free evening
  2. Not a ramble at all - I was really leaning toward Mono. Ultimately, OSC just suited my ability and expectations. As you say it is nice to have a recognisable image at the end of the night. They are not award winners by any means but if you look at my very first images compared to the newer ones it like I've hired Hubble I am planning to upgrade my mount in 2020 and once that is up and running I would most probably look to include a mono cam and filters. I think to jump straight into that would have been a bridge too far for me.
  3. I have read that the 294 struggles when it is cooled right the way down - uneven cooling against the sensor. I have so far only brought it down to 0 so cannot comment. I plan to run my winter images at -15 at most. I have also read that pushing exposure time too long can again bring up issues. That isn't a problem for me as I have so far primarily imaged unguided at 60's but only plan to run guided images at 180 - I am using an AVX.
  4. I just thought I would throw in my 2 cents along with some images in the hopes that it might help someone who is sitting on the fence. I still have a long way to go, good calibration frames is the next task but I am loving the 294. For me learning how to use a dedicated astro cam via the OSC route has really been great.
  5. Hi All I have the below for sale: Celestron Edge HD 8” SCT Dew Shield T adaptor for Canon Excellent condition, obvious indents on the dovetail, primarily used for visual and lunar imaging. For the right owner it really is a cracking scope, easy to handle and pinpoint starts across the FOV. Pictures to follow when I finish work. I would like £950.00 (RRP £1,280.00). Collection ideal (I am based in Essex) however I can arrange courier at added charge. Clear Skies
  6. Thanks! I was using a canon 700D before I got the ZWO. It took me a while to get the hang of the new camera but I do think it is the way to go. A couple of major benefits right off the bat are that you can cool the camera and also create calibration libraries. Rather than for example shooting darks at the end of your session.
  7. That is great to hear! I have the ASI294 I am assuming I just need to ensure that the mono camera I go for has a similar size sensor etc? I would like the asi1600 pro but need to properly look into it.
  8. Hi All - I thought I would throw this post together as I like many people spend hours trawling through forum posts when I am deciding to invest in a new Astro toy. After following the well trodden path of DSLR imaging, spending some fabulous nights taking pictures of the night sky you come to that split in the road. A dedicated astro cam - OSC or mono!? The respective camps will come together and argue this way and that about the good and bad of each - OSC useless under moonlight, mono you have to take calibration frames for each filter etc etc. It can be quite daunting d
  9. Cheers mate. Crikey we may be in trouble then! Hopefully it comes out nice. To be honest, I have never imaged M33 and considering the conditions, no tracking and my beginner level gear - I am already quite happy! When I have a finished data set will keep in my re the colour. Clear Skies
  10. Over a fully moon lit weekend in bortle 8 skies, I managed to get 4 hours unguided data on the Triangulum Galaxy - I think my expectation was so low that I am actually quite happy with the end result. I will attach both nights images below. Scope: SW ED80. Camera: asi294 (cooled to 0) Mount: AVX. Subs stacked in DSS and processed in PI. I have two questions: (1) I wonder how many hours under the correct conditions would really bring this image to life? I know the rule of thumb is as many as possible..but I wonder what other imagers use as a ball park, I was thinking 15-20.
  11. Thank you again Louise for making me revisit this - I hadn't factored in the 294 has 6.5mm of back focus already. So I was indeed out! Corrected now
  12. Hi John - I am based in Essex too so encouraging news you are having success with the Camera. I have no doubts it is a capable piece of kit, once I get it up and running. My previous gain setting was 200 which was resulting in Mono images. I haven't added any calibration frames as I only wanted to see if I could get some data that produced colour - Looks like lowering the unity gain solved that. Now to collect better data when the Moon isn't so obstructive. I had a dark library for the winter (-15 same as you) but now we are getting in to the warmer months I need to redo for the summer se
