Full disc in Ha 05/11/2014

Recommended Posts

Hi all

Really really struggled to get this working in photoshop. I think I've screwed up the exposure on the prom capture so the disc ended up being a fair size larger than the surface detail which was always going to give me a bit of a halo around the image. Hope its not too bad but comments and advice are always welcome :)

Taken with the Coronado Solarmax SS60 and PGR Grasshopper today, 700 frames proms, 1000 surface. Not much happening today when I took this which is a shame because I've just seen some cracking pictures of looping proms from yesterday!

Clear skies all

Cheers

Will

Solar Full Ha Disc 05/11/2014

Looks top notch to me. The seeing has been really bad this week and to get anything has been a struggle.

You might want to try one exposure for the surface and one (over-exposed) for the proms, then combine in layers? This is the usual method for a full disc with proms.

Personally I think colouring the disc orange/red and the proms light blue (with a bluish background) looks really natural and helps bring out the detail in the proms.

Thanks Robin, yes thats the method I've used here. Surface disc and proms taken separately and combined in PS. I think the problem I had was that a) there wasn't much happening in terms of proms so I've B) pushed up the proms exposure too high to try and force it. What ended up happening is I increased the diameter of the prom exposure a bit too much so increasing the surface detail mask and feathering it has led to a 'haloing' effect. 

Having said that, I'm pleased with the way it has come out and really appreciate the great comments too, it means a lot :)

      I currently have a Canon T6 with a Opteka 500mm f8 lens ($87) that I use for lunar and solar photography. I recently purchased a full frame Canon EOS R and am thinking about getting a 800mm f11 Canon RF lens ($899). Will the quality on the new canon lens be significantly better than my Opteka lens? Is it worth the upgrade? Also, should I use my new full frame or my crop sensor (1.6 factor) to shoot? I want to get the best quality possible.

      Selling the Astronomik 12nm clip in Ha filter for 120€. Bought it for 270 usd including vat, customs and shipping so it's a really good price.

      The filter is still in excellent condition, used only twice. No fingerprints, no scratches not even dust (image attached).

      I will also handle the shipping through my post office without cost. If another shipping method is requested, then we'll have to to discuss the price.

      Contact me if interested.

      Clear Skies,
      Anthony

      Hello,
      I'm selling these 2 filters since I'm getting a mono astro cam. The filters are barely used and in perfect condition, no scratches, no fingerprints, not even dust. They are both amazing filters, probably the best investment I've made. I've attached some images
      taken with these filters, using a 100$ celestron newtonian, a 250$ Canon 500D and the infamous AVX. Also attached are images of the filters showing their perfect condition.

      Original price including VAT is 155 Euros (around USD 182). I got it for around USD230 including VAT, shipping and custom taxes.
      Selling for USD 100.

      Selling for USD 150
      I am willing to ship them on my own expense using LibanPost (from Lebanon). Shipping might take time; if you would like to use some other shipment method please contact me to discuss the price. 
      Feel free to buy one or both together.
      Let me know if you have any questions.

      A few months back, i bought my first mono camera, an Atik 383l+ from Martin @Xsubmariner off here. I hadn't had a chance to give it a whirl until last night. 
      I thought about getting the 80ED out, but i've been wanting to do some widefield stuff for a while, so i attached an old Tamron 135mm F2.8 vintage M42 lens i picked up last year for next to nothing. The lens needs to be stopped down to F5.6 (perhaps less, i haven't tested though) to produce acceptable stars in broadband, but i was hoping it could be used more wide open for Narrowband. I used step-down rings screwed on to the end of the lens hood to bring the aperture down to 37mm, which is about F3.65 (i did briefly try it wide open in Ha, and it wasn't that bad tbh, but i could still make out some comet-shaped stars in a few places so i opted to stop it down a bit to play it safe). I have a TS Optics filter drawer in the optical train, so i can still swap out filters without too much fuss. I still have about 3-4mm of extra backfocus space to spare, but i can already find focus as it is, so i'm not sure if it's that important that i haven't fully used it all up.
      Focusing was tough. I was focusing using a Bahtinov mask on Deneb, and i had to use 10s subs (subframes) at 2x2 bin to get bright enough spikes for Bahtinov Grabber to pick up to the spikes ok. Even then, it was showing the focus error moving about quite a bit, even without me touching the focus ring. In the end i just got it as close as i could and went with it.
      Conditions were not great. Some clear spells, but there was a lot of cloud passing through. I figures it would be good enough for a test session. The Phd guide graph looked horrific, and was somewhere in the 1-2" range (image scale is 8.4" so not a big deal hopefully). I bodged together a couple of old dovetails to add enough weight to counter-balance the 5Kg counterweight. It just about does. It's not perfect by any means, but hopefully sufficient for this purpose. 
      I would ideally like to shoot 1200s subs, but couldn't last night due to the constant clouds (Phd lost the guide star countless times). I was about to give up, but persisted and aimed for 600s subs. Glad i did, as i ended up with 6 useable subs, even if a couple were affected by some thin cloud. 
      Did a quick stack in APP and a 10 min process in PS, just to get a rough idea of what i can expect from this. I used Flats and a couple of Darks just to do a rough calibration. Didn't do any gradient reduction, was in too much of a hurry after packing up last night. Overall i'm fairly pleased with how it performed. I'm obviously not aiming for Samyang 135mm F2 levels of performance here, but for purely NB bi-colour mosaics i think it can do a job. 
      I've included a picture of the rig below as well, in case anyone's interested.
