    First Image of 2019 - M81 and M82

    Thank you, yeah the top image is taken with the Esprit 100 and 414EX combination. I've had the Esprit only for a relatively short period, but finding it fantastic, it's got great construction, well packaged and has performed really well with everything I've thrown at it so far. I went from the LX90 8" SCT as my main scope, to this being my deep sky set up, wider field of view, handles stronger wind conditions with excellent focus control by comparison, the LX90 I shall use for planetary nebulae and lunar/planets now. So for me the change was fairly dramatic, not sure what you'd experience/expect going from the 80 to the 100. Would be interested to see what you get out of it, not spoken to anyone with an identical setup yet.
  2. It's been months of rain and clouds down here in Cornwall, so I can honestly say I started feeling a little rusty by the time I remembered in which order to do things whilst setting up! Set up the scope and whilst a nearby street light is a bane, I decided to go for long exposure shots in wide-band RGB and picked two galaxies I've imaged before, but separately through a much longer FL telescope (Meade LX90 8"). With the Esprit 100ED and the same camera (ATIK414ex), I can "just" get them both in shot, along with some interesting background fuzzies, who's distance fascinates me, and I plan to research. This image is really no where near complete in terms of data, I manged: R 17x600s G 12x600s B 18x600s Guiding came out nice with an RMS of 0.45", so glad I discovered drift aligning through PHD2 those few years back. Want to get the data sets over 30x600s per channel, and then do a run of 20 or so H-alpha exposures in the 1200s range to pull out the star forming regions in M81 and capture the full extent of the starburst in M82, which showed up nicely in my 2017 photo with the LX90 8". Hoping we all get some excellent clear skies this ear.
  3. Yeah, tried running it through two laptops and my desktop, no difference. Sadly this is starting to seem like something out of my control, and will require me to save for some time to get a new mono camera. Annoying, but manageable, it's thankfully solar min currently.
  4. No one ever got back to me from ZWO, and no one else had any clues, past few years I have been focusing on deep sky stuff, had a few sunny days, so thought "new rig, new drivers", might be worth a go, nope, still giving me the same garbage performance, incredibly frustrating. I don't recall seeing the interlace patterns on lunar images, my image is 100% and sharpened, here's another one showing the limb, again sharpened, you can see how awful it is in terms of ruining the view of proms etc.
  5. Well if certainly says MM on the camera and FireCapture/windows is reporting an MM being plugged in.
  6. I've had this camera for some time now, about 3-4 years, and initially I used it for some solar imaging, but these days I use it for a guidecam, and it does a perfect job of that, however, tried some solar imaging and it's showing a really grim interlace pattern, I've tried different shutter speeds, gamma settings etc. I've tried different USB ports and even different cables. No matter what, I can't get rid of it. am I missing a trick, is this a software issue (drivers)? Using FireCapture and ASI2.

    IC1396A - The Woman Walking Away

    No star layers used, simply the raw data for each one, mapped to colours, I've attached a screenshot of the layers used in this image. Only one is clipped, which was "selective colour", applied just to make an slight "artistic" tweak to the palette.

    IC1396A - The Woman Walking Away

    I only have Ha (Red) and O3 (Blue) so in Photoshop I assign them to those colours and then use a blend of Ha/O3 to produce an artificial green channel, which gives an overall "true" colour result, but leaves all the stars white (bar halos and other artifacts). Hope that helps. I am glad it's not only me that fails to see the Elephant's Trunk, though the region you highlighted makes sense, so I will go with that! I guess all in all the only "official" name is it's rather plain designation.
  9. A few weeks ago I started work on this with the H-Alpha under full Moon conditions, and despite that Moon, got great contrast. However OIII was very washed out. Last night I was able to finally start grabbing OIII data and have created this "work in progress" Bi-Colour blend. It's made from 2*16*720s in Ha and 2*16*720s in OIII, with the aim of getting SII and increasing the data capture to around 30*720s in each channel. Now here's a question...where the heck is the "Elephant's Trunk", I look at this from every angle going, and I see E.T.'s finger, Mufasa on pride rock, and most strongly a long haired woman, with her back to us, the left hand structure forming her neck/shoulder and the lower region a skirt....but no darn trunk!

    IC 1396A - Elephant Trunk in Ha

    Ha Raw OIII Raw Both are made from 720s exposures x 16 frames. The lack of detail in the OIII suggests a couple of things to me, either there's not much OIII in the region, or that the full Moon was causing a contrast wash out. Admittedly I plan on getting around 30x720s in Ha, but now considering either longer subs for the OIII (or though does that cause an inaccurate balance of data), or waiting until the Moon clears off (when it will no doubt be cloudy). Anyone have thoughts on this, finding Ha shots of nebulae is easy on the web, finding Raw OIII data to look at online is tricky - so really hard to know what to expect from this filter. Yeah these are all taken with the ATIK414ex, and I agree with that, clear nights always seem to fall around annoying fat Moon time.
  11. A little bit of work in progress, managed two panels of 16 images @ 720s per image, so a little over 3 hours per panel. This was in "not ideal" conditions, 22mph gusts of wind, periodic clouds and a rather big fat Moon. Got to love narrow band for it's ability to fight almost everything. Planning on OIII and SII runs, indeed it's clear tonight, so will be making an attempt tonight. I've imaged this region before using my LX90 8" with a reducer, but it was a three panel effort with a much narrower field of view, so thought it was a good idea to revisit it, and have a proper go.
  12. Last night I had to work at the beach bar I run, but it was clear and from next week I am hosting star parties at the bar. So thought I'd set up the scope, pull a few pints and attempt to image M33 for the first time. It sounds obvious now, but it turns out wooden decking does not make for a stable platform for a telescope, so going to have to re-think the location for the scope during the nights (thankfully I have power leading down to a grass area) Despite this, once the customers had gone, I managed to get 6x480s in each channel to put this together in Photoshop (levels, saturation, curve, done). Going to have to revisit this object from my usual viewing platform, and get a lot more data, love the details held within the galaxy itself.

    The Pacman and the Palette

    Thank you all for your feed back on this, I have just emailed Baader with the sample O3 data and a photo of the filter box/invoice (which was fun to dig up). Hopefully they can help. Still playing with PixInsight, I really like it, just playing with every tool trying to study it's function and potential use. Going to be doing some LRGB imaging on Thursday, still not made my mind up about the target, but will be using PixInsight to process it and Photoshop to compare my results. - The debate is Stephan's Quintet with NGC 7331 or M33, neither of which I have ever imaged....oh the choices!

    The Pacman and the Palette

    40 minutes of pressing who knows what in my trial of PixInsight....powerful as this program is, I must confess to finding it "unintuitive" at first blush, video tutorials full of faff, and PDFs with not a drop of text...I shall persevere, I have 45 days with it. Oh and I am sorely tempted to save some money and bin the Baader filters.
