  1. Hi there. No need to panic this is easy to sort out. Firstly, GoTo and mount alignment/tracking are separate entities. Setting up GoTo 'teaches' your set up where things are in your sky. So accurate polar alignment is not crucial for an evenings viewing and accurate finding of objects by the GoTo function. What accurate polar alignment will do is make sure your view (or a camera's view) doesn't 'drift' substantially during the evening hours. If you have Synscan then its even easier. Synscan has a function that will do a pretty accurate polar alignment for you without going near the Polar Scope. That's what I use. Make a rough polar alignment by setting the mount axis pointing roughly at Polaris. Then use the Synscan handset Polar alignment routine to do the PA for you, its all in the manual. When you do that make sure you do a 2 star alignment (not 3) using 2 stars on the same side of the meridian. It takes about 10 minutes in all.
  2. Hilarious.
  3. Still can't believe what a cracking deal this is. Now just waiting for the deal of the century....
  4. Oh. Sky Safari has NGC3610 in UMa close to your region sketched but I can quite picture the asterism from your sketch which I'm sure is more accurate than Sky Safari!
  5. Tough that one. NGC3610? Three of us on Saturday night caught 41P quite easily in the ED80 and 120 I had set up in tandem Alt Az mode. The Sky Safari projection was spot on for us.
  6. Hi Sean. I'm not sure there is one thing I do that makes it "fluffy". I don't double stack but probably the majority of the effect you describe is down to sharpening and Lucy-Richardson deconvolution, so software related. As we are probably only a few miles away from each other I am happy to suggest a get together in which we can share processing routines. Send me a pm if you fancy that and you think that would work. I am between Harrogate and Ripon.
  7. Very nicely done.
  8. As you may have realised from other posts I was very busy day and night on 25th. Make hay while the sun shines I say. So I have only just got round to going through my Ha captures. Here are two with some active proms and a couple of active regions taken two hours apart. The prom near the top develops into what looks like a terrestrial tornado funnel maybe? Usual set up: Lunt 60Ha and ZWOASI174MM. 10:56am 1:02pm
  9. Thanks Pete. I wouldn't normally image planets that way but the ED120 was 'cutting' right through the seeing so I just thought I would give it a go. The 290 is lightning quick on frame rate too.
  10. Ok. I moved on from all that to using Autostakkert. It does it all in one pop and with a much easier interface. The only thing I refer back to Registax for is RGB align. Unlike most, I don't use wavelets either as it smashes the hell out of my data.
  11. It's me again. Here is a solo Jupiter this time to follow up my wide field shot posted earlier. This is with the ASI290MC on the ED120 at native f/ of 7.5 and f/l 900mm. The most I can squeeze out of the average data and a 1.5x enlargement. One stack of about 600 frames in AS!2. I should try the camera with my C9.25 at native too if the clouds will move this week of course.
  12. Thanks very much. I see I have put the processing date in not the capture date. Should read 25th March!
  13. I'm wondering why have you used PIPP?
  14. Last night was very clear. I had set up the mount in Alt-Az mode with the ED80 and ED120. A few folks came round for a viewing session, the biggest wow coming from the spectacular view of Algieba through the 120. Anyway, when they had all gone I had a look at Jupiter and despite being around 20 degrees in altitude and poor seeing I put the ASI290 on to it at native f/7.5. I can get Jupiter and its moons on the 'widescreen' chip of this camera at that f/l. Here is the result of two stacks, one for the planet and another for the moons. Stacked in AS!2.
  15. Another great shot. How I dream of catching Jupiter at an altitude of 65 degrees!
