    Cassiopeia Widefield (NGC7635;NGC7538; M52; Sharpless 157)

    Hi everyone - This is a widefield shot I took of the bubble nebua (NGC76350, Lobster Claw Nebula (Sharpless 157), M52 star cluster and NGC7538 in Cassiopeia using my Altair Astro 72 ED_R and Canon 450d late last year - finally got round to soing it some processing justice. Shot in Hydrogen Alpha with colour added on PS CC for contrast.

    This has been a labour of love I don't mind telling you - so much contrast in the dust and reflections - but glad it's done C8+Hyperstar+178MC Cool - 32x5 min subs taken Dec/Jan - processed in Pixinsight, PSCC and LR

    My current eyepiece pairs

    Although i don't consider myself to be an eyepiece hooligan as such......... i thought i'd have a look at all of mine together. They number 14 😳 From left in order of focal length : TS Wide angle 26mm illuninated reticule. Used for initial alignement purposes only. 28mm Edmund RKE 24mm Tv Panoptics 19mm " 16.8mm Orthos 14mm Denkmeiers 13mm Naglers 9mm Nagler. Out of this little lot, the Pan 24s are my favourites, and are, together with the Pan 19s, and hopefully the D14s, my 3 main workhorse eyepiece pairs. I brought the Nagler 9mm on a bit of a whim, used, for a good price, with the idea of pairing it up as a high power pair. Problem is, i don't find them, like their bigger brother 13s particularly comfortable to observe with. I will probably sell the 3 of them eventually, and look for some 11mm Naglers if i can source a used pair. 9mm is likely to be too much power anyway. We will see. At the other side is my 28mm, 2 inch TS illuminated reticule. I tried it out the other night for the first time. The IR is great, and is laser etched. The illuminator, while reportedly poorly designed, works really well. The eyepiece has a load of eye relief, and is of a wide angle design. Build quality is good. If i want to increase power for more precise alignment i have Powermate options. As i was only doing alignment tests to see how my new alt-az encoders performed, and i wasn't that interested in a proper viewing session as such, i decided to leave the reticule in and use it on its own, cyclops style. Heres where i was taken aback....... COMA. My word, i never realised what it was all about until i looked through this eyepiece. It was pretty dire to be honest ; the outer third of the fov had those unpleasant comet shaped stars. Even in an F4 Dob, with my Tele-vues its never been an issue. They are that well corrected. I never needed the Paracorr at all. Also the binoviewers corrector lenses help remove it as well. But this was Coma on a big scale and i'd not seen it before. Of course, the IR eyepiece is not about edge of field performance, but rather, as designed, as a premium reticule eyepiece. In that regard, it performs very well indeed. It's a keeper.

    Denkmeier D14 Pair

    Every now and again, i have a bit of a clearout and sell some gear. I've recently sold 5 telescopes : all 3 of my refractors, and both my catadioptrics. At present, just my Dobsonian remains. Also, my 2" glass (N 31mm) 2" star diagonal, and my Powermate have found new homes as well. I've been after a pair of these for a good while, and with funds in the black, decided to finally purchase what i hope, after a long search, is my goto mid / high power eyepiece pair. Magnifications for high power viewing will be : Refractor : 170x approx Dob 96x / 152x / 192x approx, with the 3 'Powerswitch' settings Enter the Denkmeier D14mm (From Denkmeier Optical, New York, USA) They are pretty beefy (i'm not talking Delos size though) Allegedly, they are actually 15.2mm rather than the stated 14mm. Puzzling. Some stats : 250g each - pretty heavy 20mm eye relief - nice 65ΒΊ fov - similar to Panoptics Big eye lenses - nice, similar to Delos 'Bat wing' eye guards - very nice. Some pics..... Comparison with 13mm Nagler One of the things i don't like about the 13 Naglers is the tight (for me) eye relief, and the abnormally long barrels, which prevent them from fitting flush in the bino. No such issue with the D14, and they have a smooth barrel, with no silly tapers or undercuts. In the Mk V from above They fit well in the Mk V, and are as big a pair as i would want (Delos was way too big) They don't match the perfect asthetics of the 24 Panoptics though. Here they are in my Newtonian binoviewer system. Check out the weight. Now you know why i need a Moonlite focuser on the Dob. This is a pretty heavy load on the focuser for a visual set up.

    Conditions were poor, with cloud ruining most frames but I rescued 26 and stacked them. To the bottom left, the sickle of the constellation of Leo is partly visible. https://www.flickr.com/photos/philippughastronomer/39773660273/in/dateposted-public/

    ED80 Binoscope first light

    Well would you beleive it, a pair of 32mm Celestron Plossls arrived yesterday, to be used in the bins for low power, 18x, and it was clear for a bit, enough to have a quick second light through the ED80 bins. Early on I caught the thin crescent of tge moon low down before it set. Very nice at low mags with earthshine all the way round but higher mags were out due to atmospherics. I had about 15 minutes on this then it clouded over. About 21.00 I set up again and revisited the objects I viewed on first light but this tine with the 32mn eyepieces. Firstly the 32mm eyepieces with their good eyerelief were really comfortable to use, making observing very relaxed. Collimation with them was easy as well due to the low mags. First on the agenda was the Double Cluster, now it was good before with the Vixens at 25x but at 18x the colours of the stars came through really well. There were distinct reds and yellow components, lovely. M31 was better with the Vixens but 110 and 32 were still prominent in the 32s. M42 was washed out a bit by lp with the 32s but the Vixens at 8mm showed much more than the other night. This time I got M81/82 dead easy with the 32s. M45 fitted fully in the 32s fov and what a great sight very 3d. M36,37,38 and then M35 all looked good. I am very pleased with this rig now, it performs about the same as a 5" I reckon pulling in similar faint detail but the experience of having an objective for each eye at higher than normal bino powers is really good. So, conclusion, was it worth it? Hell yes! From the fun of learning, building to using it. Im very pleased with it and looking forward to a dark site session
