Eastern Veil - first light with my new (second-hand) QHY8L - and my first ever colour image. Taken on 21 Sep, 2017 @ 23:15 ~ 24:00 QHY8L camera @ -5 C Quattro 8" with CC Avalon M-Uno mount 10 x 5 minutes, guided & dithered (with PHD2 / Nebulosity) FLATS, BIAS, Bad pixel map, de-Bayer, and a bit of stretching and saturation (also in Nebulosity.) It's somewhat cropped since the CC spacing was a bit wrong. -

The Lagoon Nebula ( Messier 8, NGC 6523 ) in the constellation Sagittarius - by Mike O'Day ( https://500px.com/mikeoday ) The Laboon Nebula ( M8 ) is visible to the naked eye under dark skies from most latitudes except the far north. Seemingly covering an area about three times that of the full Moon, M8 actually covers an area somewhat greater than 110 light years and is around 4300 light years from Earth in the Sagittarius-Carina spiral arm of the Milkyway galaxy.

I'm planing to delve deeper into AP - previously did only widefield with my DSLR - so after digging the internets for the past few days I decided to buy a fast newt along with all the additions that will be needed. This is what my current list looks like and some parts of it is what I need an advice about because there is more than one possible choice and I'm not sure what to pick. * NEQ6 (just to be a bit more future proof) * SW Quattro-8CF (I know that it will be more complicated to handle compared to something like 80ED because of collimation (probably needed each session?) but I'm more than willing to cope with that) * Coma corrector (?) - really not sure which one to buy, my current picks are either Baader MPCC Mark III or SW Aplanatic Coma Corrector. From what I've read, SW one seems to be better. I've also seen some good reviews of Paracorr but this one is over my budget * OAG (?) - I decided no to go for a guidescope because I really want to keep things compact as I'm going to transport whole setup from time to time, also possible flexure issues. Plus, I may consider getting SCT in the future, so I'd like to be able to reuse current setup with it. Here, I'm not sure which OAG to get. I will be imaging with my Canon 60D and, when budget allows, I'll upgrade to Atik 414EX. Would be cool to get something that would work with DSLR and won't have backfocus issues later, when used with filter wheel and CCD. * guider - Lodestar (I suppose it will be sensitive enough to be used with OAG?) What do you guys think about this kind of setup? Also, any advice on what coma corrector/oag should I get?

Decided to take the plunge and replace my (very) old Fullerscopes 8.5" f6 Newtonian by a 12" Quattro (which at f4 has much the same focal length as the Fullerscopes). Turns out that I can't get anything much bigger in the observatory, so although an f5 12" would have been easier on coma etc, it would probably have hit the walls! It arrived in two parts - one box for the OTA (large enough to hide a person in) with secondary attached and one smaller one for the primary mirror (in its cell) and a pack of springs and screws. Seems I got the last one in OVL's warehouse, and it went 'missing' for a few days, so for a while it wasn't clear if there were any at all in the warehouse! Turned out someone had 'put it aside' then promptly forgotten about it. Anyway it turned up only a few days late in the end. Strangely there were no instructions in either box, so attaching the mirror to the OTA required a bit of guesswork - turns out you need to unscrew the white 'collar' at the end of the OTA and attach this to the back of the mirror support, then man-handle the whole lot back into the OTA. The assembled beast is not exactly light, but it can be carried by one person, although attaching to my EQ8 was a bit of a struggle. Did a quick collimation with a laser, which showed the secondary was surprising well-aligned to the centre spot on the primary, which is just as well so far I have not been able to loosen either the centre screw on the secondary, or any of the three adjusting hex screws! No idea how Skywatcher have managed to get these so tight. Another slight issue is that I was planning to buy a Skywatcher Aplanatic coma corrector, but due to production difficulties none are expected in the country until the end of October. Anyway, in the meantime, here is the first light image of Albireo (28secs, ISO1600, Canon 1000D), cropped to hide the coma! NigelM

Comet 252P/LINEAR passing through the constellation Mensa and approaching Earth on the 18th March 2016 by Mike O'Day ( 500px.com/MikeODay ). Comet 252P/LINEAR is a near-Earth comet that was discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) project in April of 2000. 252P has an orbital period of 5.3 years and passes close to the orbit of the Earth. In 2016 it passed 'very close' to Earth (in astronomical terms) on the 21st of March 2016, when, at its nearest, it was only 14 times the distance to the moon (~5.3 million kms). This image was taken three days before comet 252P/LINEAR made its closest approach when it was at a distance of about 5.9 million kms ( position as at ~16:22 Fri 18 Mar 2016 UTC as seen from the Blue Mountains above Sydney Australia ) Links: https://500px.com/MikeODay http://photo.net/photos/MikeODay Details: RA 06h 40m 38s, Dec -80 deg 18' 37" (Epoch 2016.2) Skywatcher Quattro 10" f4 Newtonian Skywatcher AZ Eq6 GT Mount Guiding: Orion Shortube 80 guidescope, Starshoot Autoguider, PHD2, (guiding on star) Baader MPCC Mark 3 Coma Corrector Hutech IDAS D1 light pollution filter Nikon D5300 (unmodified) Field of view (min) ~ 74 x 49 Stack of 185 x 7sec images @ ISO6400 Pixinsight (incl.

The Rosette Nebula and Cluster ( NGC 2237 and 2244 ) in the constellation Monoceros edit: updated 30th Dec with improved colour balance and slightly increased brightness ... ...... original: ( please click / tap on image to see larger and sharper ) Still a work-in-progress really... with only 10 x 4min exposures for the main 'lights' before the clouds came over. I will try to add some more data when the moon has gone I am still experimenting with how to get the best out of the D7500. With the very warm nights ( low to mid 20s all night ) the 'warm pixels' are very noticeable so I reverted to my old practice of in-camera dark subtraction. This worked quite well and produced a nice smooth noise floor in the integrated images - albeit at the expense of more exposures. ................. Identification: The Rosette Nebula ( NGC 2237 ) is a large, circular emission nebula in the constellation Monoceros. It surrounds a cluster of hot, young stars known as the Rosette Cluster ( NGC 2244 ). ( SkySafari ) NGC 2237, 2244 Caldwell 49, 50 North is up. ..................

Nebulae and Clusters in the North East Quadrant of the Small Magellanic Cloud ( Tucana Constellation ) ( Contains: NGC 292, 299, 306, 330, 346, 361, 371, 395, 411, 416, 422 & IC 1611, 1612, 1624, 1641 ). The Small Magellanic Cloud (SMC) is a "small" spiral galaxy about 7000 light years in diameter and is one of our near neighbours. At 'only' around 200,000 light years distance, it shines brightly in the southern sky and is clearly visible to the naked eye even in moderately ligh polluted skies.
