    Pelican and North America in Ha

    Hi, Pelican and the North Anerica nebulae in Cygnus. Photographed over two nights 20 ten minute subs with darks and flats. Stacked in DSS, pre-processed in PixInsight, finished off in Photoshop. I like the curly dark nebulosity, haven't managed to pull that out as much on previous attempts at this target.

    Spent time on this again last night but decided to add some previous data as well. All taken with 150 PDS Hypercam 183c NEQ6 Guided and dithered in APT and PHD 2.6.8 all given the same treatment, DSS and PS6 First, last night. 10 x 120s at gain 500 + Darks and Flats. Next, added previous, so 40 x 120 at gain 500 + Darks and Flats (I did not use the HLVG on this image) Then I added some Tri Band filter sub, so 50 x 120/240 at Gain 500 + Darks and Flats I'm not sure the above is a lot better than just the 10 x 120 I took last night?? Comments welcome Ron

    Bempton Cliffs

    Went to Bempton on Thursday, weather was pretty bad driving up there but once we arrived the sun came out. We left about 15.30 for the two and a half hour drive home and after dinner I looked at Birdguides and was gutted when it said there was a Black Browed Albatross at Bempton at 16.30. Apparently the last one was in 1982 so I have a long wait for the next one. There was loads of birds at Bempton and Flamborough, I have never seen so many Gannets. Hope you enjoy the photos.

    Occupational therapy

    For a bit of light relief I decided to have a go at building an Orrery. This one comes from Sweden, made by Induku. Instructions are well organised, well illustrated, thorough and in English English. The most difficult bit was making the base. It could really do with a jig for this because you finish up trying to hold too many bits in place before it clicks together. I failed with this, and spent an hour or two sorting out the mess later. Then you get on to the main mechanism. What you are effectively doing is constructing a plywood gearbox. There's a reason why your car doesn't have a plywood gearbox, and you need to bear this in mind: there has to be some slop in the system otherwise it won't turn, but tighten it up to remove backlash and you either bind it up or destroy teeth. I used a lot of paste furniture wax to lubricate things before they ran smoothly. Scientific accuracy: 3/10 Entertainment value: 11/10 Pride at getting the thing to work properly: 15/10

    Rare White Pyramidal Orchid

    We went to Pleasley Pit Nature Resrve this morning on a grey, dismal and wet day. It's near junction 29 on the M1 .. and an excellent place for orchids. We were lucky to find a white pyramidal orchid. These are normally bright pink. Cath's a huge wild orchid fan and we have travelled over the country looking for them. We have seen white versions of many, including early purple orchid, common spotted orchid and fragrant orchid, but in all of the years we have done it, this is the only white pyramidal we have ever found.. The normal is pink..

    NGC6357 - Lobster Nebula in SHO from Siding Spring Obsy

    Hi everyone - hope you're all well. I'm swapping some kit around in my home obsy at the moment but given the weather I don't think I'm missing much being out of action. So I bought some scope time from iTelescope.net and grabbed this image of NGC6357 aka The Lobster Nebula in Scorpius for an SHO composite of 3x10 min subs. Hope you like it

    IC 1318

    I started out trying to run run NINA and it failed to connect the ccd so I tried APT instead to make sure the old cam still worked and managed to grab just the 4 subs. Taken wih the TS 71 and the old SXH9 and the 7nm baader filter. I have since got NINA to connect so that is one for next time.

    Little Egret sighting

    Nice to see one of these on my walk this morning around Darley park. At first i thought it was a Great White Egret due to its Heron like size, but on closer inspection, i was wrong. The yellow feet give it away, as well as some crest plumage. This is a 'Little Egret' I've not seen one locally before ; at one time they were a rare visitor from Mediterranean areas and only found on the south coast of England, but they are more common now further north. Not the sharpest pic : full 10x zoom on my iPhone (11 Pro Max)

    Rosette Nebula

    Going through my RAW file archive today, I came across some images of the Rosette Nebula taken back in March but had never been processed, so I've spent the evening trying to drag some detail out of the noise. An unmodified DSLR is probably not the best imaging device to use on this target and I could have done with an hour or two more integration. Still, here's the result, 35 x 180s with my canon 200D and 400mm lens at F5.6, ISO 1600. stacked using DSS and processed using IRIS.

    Obsy update

    I have been using my obsy for a while with a lift-up roof, but for a number reasons I need to change it, not least because we get freak blasts of wind even on dead calm days! Last Sunday morning at 1.30am it suddenly banged shut with a heavy and loud thud!! Luckily I was imaging in the other direction so no harm to the kit was done, so a re-think!! Anyway I decided to alter it to a roll off roof design (as Phil suggested last year!!) So having got the time (only doing part time at work atm) and the materials I set too..... Roof removed. Runners added. Rear supporting framework and edging added. Front valance fitted. Started painting but there was a storm brewing! I still have the runners to fit when Screwfix get them in stock but at least it's watertight for the moment! More to come when I finish it! Ron

    Update to New Obs

    Not completely finished, but well on the way. The purling’s supporting the roof structure and runner rails have been fitted, a few minor adjustments to make, then the roof will slide a full 3 meters without bolts snagging under the existing roof. The pier has been fitted, levelled and roughly pointing to Polaris. Weather brush seals being fitted atm and the front door painted and brickwork, looks like a brand new garage with a sunroof 😂 I’ve still 3 weeks left before my new scope arrives via boat, so plenty time left 👍

    Creating a custom landscape for Stellarium

    I’ve recently created a custom landscape and it’s been really helpful, allowing me to see the stars and planets like they would from my observatory (i.e. the garden!). It’s fairly straightforward, so I’d like to share the process. There are several stages. STAGE 1 INITIAL SETTINGS FOR STELLARIUM This is personal choice, but I find that the most useful view of Stellarium is when the daylight visualisation is off (i.e. you can see the stars during daylight hours), and the background is always visible (i.e. doesn’t go dark when time gets to night time). Press F4 on the keyboard. The View Menu comes up. “Atmospheric Visualisation” is normally ticked, note the sky normally shows daylight. I like to untick this showing the sky as dark during the day.. The other setting I like to change is on the View Menu, landscape tab. It’s the Minimal Brightness check box, which I like to have ticked. If this is left unticked, when the sky goes dark, so does the background, and you can’t orientate yourself. When it is ticked you see a light rendition of your background, so you can see what you see things relative to the background. Look carefully below, you can just see my background, it would otherwise be totally black in this night view. Having changed those two settings, make sure they are saved. Press F2 to get to the configuration menu, then on the “Main” tab, press “Save Settings”. These two steps will make getting your landscape working much easier. STAGE 2 CAPTURING YOUR LANDSCAPE. You need to capture a 360 degree landscape, taken from your observing site. This can be done as a series of shots with an SLR, but I found that the easiest method was to use a mobile phone set to panorama mode. I took two panoramas, each of slightly greater than 180 degrees. However many photographs you need for the 360, stitch your photos together, I used Photoshop, but you could use Microsoft ICE, or whichever software you are familiar with. After stitching you should carefully crop the photo at the edges so that you have exactly a 360 degree view. I found it useful to look for the same object at each side to help with the crop. STAGE 3 EDITING YOUR LANDSCAPE The first thing to be aware of is that the file needs to be capable of having a transparent background. You can’t do this with a .JPG file. So use your imaging software to save as a .PNG file, with a transparent background. The resolution of modern cameras means that at this stage the file will be quite large, much larger than when it will be used later, in Stellarium. This is good though, because the extra resolution makes it easier to carefully remove the sky. Use your software and an eraser tool, or a brush tool, and eat away the sky carefully, leaving a clean as possible break between the sky and the background. Here’s my landscape, with the transparent background shown as a checkerboard pattern. STAGE 4 GET THE IMAGE THE RIGHT SIZE. 1640 wide x 1024 deep Having used the extra resolution to get a nice clean ‘cut out’, use your editing software to make get the image the correct size. Keep a copy at the original size just in case! Reducing to the correct size can take a bit of doing. You don’t want your software to distort the image during the reduction. I reduced to the correct width, and then played around adding and subtracting to the height to get the exact size. The area above the sky can be added as transparent area, the area below I have filled with green, so can be extended or cut as necessary. Most of the hard work is now done! STAGE 5 LANDSCAPE.INI FILE CREATION I create a folder on my desktop, this time called “RonsHouse”, but whatever you like. In there put your PNG file, named as landscape.png Also in that folder, with a text editor, create the file “landscape.ini” and paste the following (blue here) lines into it.. [landscape] name = Ron, Lynn and Daisy's House in Newark description = Shedatory + Man Shed type = spherical maptex = landscape.png [location] latitude = +53d03'00" longitude = -0d48'00" altitude = 20 angle_rotatez = 180 a)Change the name to the name of your site b)Change the description to describe your observatory c)Change the latitude and longitude to describe your position. The convention on longitude is that minus is West. The latitude and longitude of Ron’s house is approximately 53 deg 3 mins North, 0 deg 48 mins West Save the file. STAGE 6 FOLDER COPYING The folder on your desktop needs copying to your Stellarium/landscapes folder. This will normally be C:\Program Files\Stellarium\landscapes. It doesn’t matter what you call your folder, the name showing in Stellarium will come from your .INI file Keep the copy of the folder on your desktop. If anything is not correct it’s better to edit there and drag the whole folder again, keeping yourself a backup. You may have to give permission to create or overwrite the folder. STAGE 7 TWEAKING. Go into Stellarium, Press F4 for the View Menu, and go to the landscapes tab. You should now see the option as described in the “name” tab in the INI file.. with it’s details. Once you are happy with it, you can tick “Use this landscape as default”, then save settings. Hopefully things look OK, but maybe at the wrong angle. You need to play with "angle_rotatez", the angle of rotation of the landscape. Play with the “angle_rotatez” in landscape.ini file IN THE DESKTOP FOLDER, then copy the whole folder again. This can be a bit fiddly, persevere, it’s worth getting it right. Don’t try and edit in the C:\Program Files\Stellarium\landscapes folder, it won’t let you save it.

    Badger Cub in a bag!

    Cath and I went out to meet two friends for a socially distanced walk near the Belper Dark Sky site this morning. Just after crossing Whatstandwell Bridge I spotted a badger cub lying on the side of the road. Fliipping awkward place to stop, but stopped and it looked uncomfortable but not actually in pain. So I picked it up in a towel and very shortly it was in a supermarket carrier bag. Delivered it to a friend we know with badger connections .. we'll let you know the outcome..
